Equipped with a wireless router from your ISP, most WiFi networks are usually fairly efficient. For at-home setups, a quality router will usually be more than enough to run a decent network. After all, even your close neighbors can normally see your wireless network. Of course, there are some exceptions.
If you live in a very large house or your ISP installed your router in a strange location like your closet, your WiFi signal may not reach every part of the house adequately. When it comes to streaming media, a weak WiFi signal result in extreme lag and choppy videos.
Luckily, there are several things that you can do to help boost WiFi signal strength. Here are some of my top recommendations for improving weak WiFi. Note that this article focuses on WiFi specifically and not on your Internet connection.
Use Latest WiFi Protocol
Wireless AC has pretty much become the standard, but if you have not yet upgraded to a Wireless AC router and are still using Wireless G or N, you may want to consider upgrading. Wireless AC has proven to be a much more capable technology that not only produces greater WiFi range, but improved and more consistent signal strength as well.

Of course, a Wireless AC router will be most efficient with Wireless AC devices. If you are using a newer device with a built-in wireless card, such as a laptop, check to see what wireless protocol it supports.
It’s also worth noting that after AC, there will be AD, AH, AJ, AX and so on. You don’t always have to be using the latest protocol, but you also don’t want to be several protocols behind. Wireless N and AC also support MIMO, which allows for multiple antennas.
Get a Dual-Band Router
You may have noticed that some routers offer a feature called dual band. This means that it supports both 2.4 GHz and 5 GHz networks. So what’s the difference? 5 GHz allows for much greater speeds than 2.4 GHz, but over a shorter distance.
A dual band router can be helpful because you’ll get faster speeds when you are closer to the router, but you can switch to the 2.4 GHz network when you are farther away since 2.4 GHz signals can travel farther and penetrate more walls. Unfortunately, you mostly have to manually switch between these two networks.
Call Your ISP
Since most people use the default router given to them by their ISP, it’s a good idea to make sure you have the best one they have to offer. Most ISPs will install a cheaper router with less speeds and less features and then try to get you to upgrade later.
If you are getting service connected, you can usually make them give you the best router before you sign up with them. If you are already a customer, you can always try to threaten to leave. Unfortunately, to get a better router, you normally will have to pay a monthly cost or buy it upfront.
However, if you buy the router upfront, never buy it from the ISP. Instead go to Amazon or eBay and buy it from there. You can always call out a technician to come and install the router, if you don’t feel comfortable doing it yourself.
Use a Cable Signal Booster
If you have cable internet, several factors can play into the actual cable signal strength coming from the cable company to your home. If you live in a busy neighborhood with many households, the actual cable power that your home receives may not be optimal. Aside from this, things like splitters that allow for a cable outlet in every room tend to weaken the signal, and the more splitters you have, the weaker the signal will become.
A cable signal booster can help give your home WiFi network the best possible signal by acting as an amplifier. Basically, these devices look and work just like normal coaxial splitters. However, they are engineered to distribute cable signals in the most efficient manner. Cable signal boosters will also improve the signal strength to your television.
Optimize Router & Update Firmware
This one is pretty much a given, but it’s always best to have the most up to date firmware for your wireless router. As technology changes, firmware updates are needed to keep the router running at peak performance.
http://blogs.montevideo.com.uy/thomasbattery
You should also tweak the settings on your router for maximum output. For example, if you are getting a lot of interference, you may want to switch channels. Most of the time it is set to Auto, but sometimes it’s worth manually configuring. It is best to consult a router’s user manual for firmware and settings tips.
Re-position the Router
For best WiFi coverage, a wireless router should be placed in a central location within a home. It should also be positioned not too close to the floor, but not too close to the ceiling either. WiFi signals travel in a lateral pattern, and most of the time, WiFi devices, such as laptops are used at midpoint within a home. For example, you usually sit on the couch when using a laptop; you don’t lay on the floor (most of the time), and you do not stand on a ladder.
Use a Multi Router Network Setup
All the methods mentioned above still won’t help you if you live in a very large home and the distances are simply too great, even for the latest wireless protocol with MIMO technology. In these types of cases, you probably need to setup a second router.
This can come in the form of a wireless extender/repeater, wireless bridge, or simply a second wireless router. I’ve already written about setting up a second separate network using a second wireless router, but you can also add a second router to the same network.
For example, if you have Verizon FIOS, you can purchase another identical router and configure it as a MoCA LAN bridge. You can configure the second router with the same wireless SSID and password, so devices will connect to whichever router is closer.
Purchase a WiFi System
These days, there are a lot of companies selling WiFi systems. These are basically wireless mesh networks. They include multiple identical routers that you connect in different locations in your home.
The main advantage these systems is that they configure themselves and talk to each other automatically. This makes them really easy to setup and you can add as many devices as you want to keep extending the range of your wireless network.
Eero is one example of a WiFi system. It comes with three access points for about $500. You can control and configure everything via an app and it takes half an hour to set it all up. Of course, you lose all the flexibility and control that you have when you purchase a traditional router.
Another company that I know is popular is Open-Mesh. Luckily, consumers can buy it too and it works just fine for residential purposes. Again, these are much more expensive solutions, but you’ll be one happy camper at the end of the day.
Add a WiFi Booster Antenna
Depending on the exact model of your WiFi router, it may be compatible with an add-on WiFi booster antenna. WiFi antennas seem to have a varying degree of mixed reviews from purchasers, but for approximately 50% of people, they are worth the purchase. WiFi booster antennas work with the same concept that retractable antennas on old boom boxes work. While the default antenna may be built-in or minimal, a standalone WiFi antenna may help improve WiFi network signals.
Use Powerline Adapter
For some people, you just can’t get a wireless signal into a certain area of the house. Maybe the wall is made of a material that blocks WiFi and therefore nothing but a direct cable connection would work. You can always try to drop a network or coax line to that location, but if that’s not feasible, then a Powerline adapter might be a good alternative.
Speeds are nothing to write home about, but it’s definitely better than nothing. You basically plug them into the wall, one where your router is and one where you need an Ethernet connection. Most have just one Ethernet port, but some like the Actiontec one above, have several ports to connect multiple devices.
Turn Off Other Devices
If you are a heavy gadget user and have tons of devices connected all around your home like cameras, phones, monitors, IOT devices, etc., it might be worth turning some things off to see if there is some kind of interference.
Other appliances like microwaves can also cause interference, so try to keep your router away from any other electronic gadget.

If your formerly shiny, new Windows 10 PC has begun to lose some of its luster, there are ways to put a little pep back in its step. Here are some quick, easy ways to improve its performance without swapping out any hardware.
1. Go opaque
Windows 10's new Start menu is sexy and see-through, but that transparency will cost you some (slight) resources. To reclaim those resources, you can disable transparency in the Start menu, taskbar, and action center: Open the Settings menu and go to Personalization > Colors and toggle off Make Start, taskbar, and action center transparent.
2. No special effects
Making the Start menu, taskbar, and action center transparent is one thing, but Windows 10 still has a lot of other snazzy, built-in special effects. To really go bare-bones on the special effects, right-click the Start button and click System.
Click Advanced system settings to open the System Properties menu. On the Advanced tab under Performance, click Settings...
This will open the Performance Options menu. In the Visual Effects tab, either choose Adjust for best performance to turn off all unnecessary animations and special effects, or choose Custom: and deselect the visual effects you think can live without. When you're finished, click OK to apply your changes.
3. Disable Startup programs
If your PC is taking a long time to boot up -- and you've enabled Fast Startup and everything -- you may have too many programs starting up when you turn your computer on. To fix this, right-click on the Start button and click Task Manager. Click the Startup tab (click More details if you don't see the Startup tab) and peruse the list of programs that start up with your computer. If you see a program that doesn't need to be there, right-click it and click Disable. You can also arrange the list of programs by Startup impact, if you'd like to see the programs that are taking up the most resources (and time).
4. Find (and fix) the problem
Windows 10 has a built-in performance troubleshooter that can help you find and fix any problems that might be affecting your PC's speed. To open the troubleshooter, right-click on the Start button and click Control Panel. Under Security and Maintenance at the top, click Troubleshoot common computer problems. Next, under System and Security, click Run maintenance tasks.
5. Reduce the Boot Menu Time-out
When your computer starts up, the boot menu is displayed for a certain amount of time before the operating system loads. This gives you time to do things like start Windows in Safe Mode. You can shave a few seconds off your startup time by changing the boot menu time-out, which is set to 30 seconds by default.
To do this, right-click on the Start button and click Control Panel. Go to System > Advanced system settings, and, under Startup and Recovery, click Settings.
Next to Time to display list of operating systems:, change the value from 30 seconds to 10 seconds and click OK.
6. No tipping
In an effort to be helpful, Windows 10 will sometimes give you tips on how to get the most out of the OS. It scans your computer in order to do this, a process that can have a slight impact on performance. To turn off these tips, go to Start > Settings > System > Notifications & actions and toggle off Get tips, tricks and suggestions as you use Windows.
7. Run Disk Cleanup
This one's a win-win. It'll improve performance and free up space on your hard drive. Disk Cleanup has been around forever, but this trusted Windows utility can still help clean out the temporary files, installers and other junk littering your hard drive. To run it, just search for Disk Cleanup, run it and click the button labeled Clean up system files.
8. Eradicate bloatware
If your PC came with preinstalled apps you don't want or need, get rid of them. Same goes for any apps you installed that you later found to be of little or no use. Right-click the Start menu, choose Control Panel and under the Programs header, click Uninstall a program. Peruse the list from time to time and select the programs you no longer need and click Uninstall at the top of the list.
9. Power plan
Make sure you aren't using a Power saver plan if you don't need to. Even desktops will sometimes feature a power-saver option, which doesn't do you any good unless you are trying to conserve battery life. Open the Control Panel and go to Hardware and Sound > Power Options to see which power plan you are currently using. For better performance, make sure you are using a High Performance or Balanced plan (or a plan from the PC manufacturer that says it's balanced).
10. Restart your PC
Is speeding up your computer as simple as...restarting it? Maybe. Restarting your PC clears out its memory and stops any processes that might be taking up resources. Also, shutting down your computer is not the same as restarting it -- shutdown is affected by Windows 10's Fast Startup, which saves a snapshot of your PC and its processes in a hiberfile for faster boot-up. Restart is not affected by Fast Startup, so if you have Fast Startup enabled, restarting your PC is the only way to fully clear the memory and shutdown processes.

Years after it first appeared, wireless charging has finally arrived on the iPhone—but what is this magical charging method that’s been on other big phones for a couple of years now? And is it really all that superior to just plugging your phone into the wall every night? Here’s what you need to know about wireless charging, and the kit you need to make it work.
How wireless charging works
The key to wireless (or inductive) charging are electromagnetic fields, used to transfer energy from one place (a charging mat) to another (your phone) through the magic of electromagnetic induction.
Essentially you’ve got two physical coils, one which converts energy into an electromagnetic field that can travel wirelessly, and one which converts that floating field back into energy again—the two coils form a transformer. That’s why the wireless charging cat was out of the bag as soon as a coil was spotted in leaked schematics for the iPhone 8.
If your phone doesn’t support wireless charging out of the box, you can often get a case or adapter that takes care of all of the necessary power transfer processes and feeds the juice straight into the handset—you don’t have to miss out on the wireless charging. Considering wireless charging pads are usually optional extras anyway, you can just add another adapter to your basket.
We’ll get on to standards in a moment, but in addition to the popular magnetic induction method we’ve explained above, you also need to know about the magnetic resonance method—in essence, it’s not all that different, but it increases charging distances, makes it easier for multiple devices to charge up at once on the same charger, and can work through more, and thicker, materials.
For most smartphone owners, that’s as much as you’ll need to know, but pay attention to the quoted voltage of your phone and your charger—the charging speed will be limited by whichever is the slower, and it’ll usually be significantly slower than plugging your phone into a wall. That said, you should also bear in mind that these specs and standards are improving all the time, as the technology gets more efficient, and the prices of the required components come down.
Wireless charging standards
As we said at the outset, wireless charging has been with us for years, in everything from electric toothbrushes to the Nokia Lumia 820 from 2012. Of course, tech wouldn’t be tech without a few differing and incompatible standards to stay abreast of.
The big one, as far as wireless charging goes—the one supported by most phones and the new iPhones—is Qi (pronounced “chee”) charging. Qi is developed by the Wireless Power Consortium, and its 247 members include the likes of Apple, Google, Samsung and just about every other big name in electronics manufacturing. The latest phones from Apple, Samsung and LG all have Qi built in.
The other main contender is AirFuel, formed from a partnership between the Alliance for Wireless Power and the Power Matters Alliance. Like Qi, the standard supports both magnetic induction and magnetic resonance, but its implemented in a slightly different way, so the two technologies aren’t compatible with each other (you can’t charge up a Qi-enabled phone on a AirFuel-enabled mat).
AirFuel (previously known as Powermat) isn’t as widespread as Qi, but some major handsets support it (the Galaxy S8 family can work with both Qi and AirFuel), and it’s the wireless charging technology that Starbucks has installed at its outlets—although the coffee seller is now adding Qi support as well.
As long as you buy accessories using the same standard as your smartphone, you can’t go far wrong, but if you’re wondering why you’ve put your iPhone X down on an AirFuel charging pad at Starbucks and it’s not working, now you know.
What you need for wireless charging
Despite the complex technologies underpinning wireless charging, and the competing standards fighting it out for market share, it’s not that difficult to figure out what you need to set up your own wireless charging solution—check the standard supported by your phone, get an accessory to match, and you’re away.
Plenty of phones now support the Qi standard, including newer models from LG and Samsung, and the new iPhones. Meanwhile, AirFuel wireless charging is available in this year’s LG G6, all the Samsung Galaxy phones of recent years, and some less well-known models. If you’re desperate to use the technology, you can invest in a power ring that slots into the bottom of your phone and enables it to be charged up by any AirFuel charger.
It’s not quite so essential to buy official accessories from the same company that makes your phone when it comes to wireless charging: All Qi-enabled chargers will work with all Qi-enabled handsets, for example, so take your pick. As we mentioned earlier though, double-check the maximum power ratings—you really want your phone and charger to match, otherwise one will be holding the other back.
Apple being Apple, it’s bringing out its own bespoke charging mat called AirPower, which is based on Qi technology. It will charge up any 2017 iPhone, your AirPods (as long as they’re in Apple’s official charging case), and the Apple Watch Series 3 (though not the Series 1 or 2). It’s not clear exactly how AirPower builds on Qi—it has some special features like multiple (Apple) device support, and charging status indicators across all your devices—but you can also charge your iPhone 8, iPhone 8 Plus, and iPhone X on any standard Qi-enabled mat if you prefer.
Samsung, for its part, also offers a “fast charging” wireless pad based around Qi technology—it charges up compatible Samsung phones faster in return for running hotter, something that’s mitigated with an integrated fan. With Samsung’s handsets supporting Qi and AirFuel tech too, you’ve got plenty of choice.
The pros and cons of wireless charging
Just dropping your phone on a mat (or piece of furniture) is obviously more convenient than hunting around for a wire and then fixing it in place, and convenience is the biggest reason to use wireless charging over the cabled alternative.
It has its downsides though: You can’t really use your phone very easily while it’s charging (not yet, anyway), and the charging is slower than it is when your phone is plugged in. Magnetic induction charging is faster than magnetic resonance, but as we’ve mentioned your two devices also need to be closer and more exactly aligned.
That might not sound the most resounding endorsement of wireless charging, but once you actually get to use it, that extra convenience can really pay off—buy two or three pads, and any time your phone isn’t in your hand, it can be charging, at home or the office or in the car. If you need to take a call or check a text, you can pick it right up and set it right back down without yanking out a cable or tripping yourself up.
Now that both Samsung and Apple have embraced wireless charging (over to you, Google), the technology should advance at an even greater rate than we’ve already seen, and that means wireless charging that’s more ubiquitous and that closes the gap in terms of speed and voltage on wired charging.
Take for example the Pi Charger, due to launch next year, which is promising to charge devices as soon as they get close, thanks to specially tuned magnetic fields. As companies figure out ways to make wireless charging even more useful and even more frictionless, it’s finally set to become the new norm for smartphones—after a very long run up.

When was the last time you cleaned your laptop? Yeah, we thought so. This simple computer maintenance task doesn't just get rid of accumulated dirt and dust--it keeps your laptop running in tip top shape.
Laptop Parts to Clean
The five general parts of the laptop you should keep clean are the case, the LCD screen, the laptop keyboard (and touchpad), the ports, and the cooling vents.
You can also open up your laptop to expose and clean its cooling system (the fan and heat sink), but only attempt that if you're comfortable opening up your laptop.
Cleaning the cooling system can help solve laptop overheating problems and related symptoms like your laptop freezing or having issues shutting down.
As always, defer to your laptop manufacturer's manual for the recommended procedure for laptop cleaning.
Materials
You'll need the following things to clean your laptop (click on the links to compare prices and buy them online):
l Isopropyl alcohol, available at drugstores and supermarkets. Because it evaporates quickly and doesn't leave a residue, isopropyl alcohol is safe to use on electronic equipment and LCD displays. Not safe to use: ammonia, tap water, mineral water, and household window cleaners.
l Distilled or purified water or bottled water. Avoid tap water, which can leave permanent mineral spots.
l Can of compressed air, also commonly available at many types of stores.
l Lint-free cloth, like the kind used for cleaning eyeglasses. In a pinch, you can use a soft, 100% cotton cloth. Do not use: paper towels, facial tissues, or scratchy or abrasive cloths.
Prepare to Clean
l Make sure the computer is off and unplugged, and remove the battery.
l Make a 1:1 cleaning solution using the water and alcohol.
l Dampen the cloth with the cleaning solution--it should be slightly moistened rather than very wet. Also, never spray anything directly on the computer; the liquid should go on the cloth first.
Clean the Laptop Case
Use the damp cloth to wipe down the exterior of the laptop. This will help you make it look brand-new again. Then open the lid and wipe the areas around your keyboard.
Clean the LCD Screen
Clean the display using the same cloth or a newly moistened one if the original is too grimy (again, don't spray any solution directly on the screen). Use gentle circular motions or wipe the screen from left to right, top to bottom.
Clean the Keyboard and Touchpad
Use a can of compressed air to loosen and remove dirt, crumbs, and everything else that may be stuck in the keys. Alternately, you can turn the laptop over and gently shake out any loose debris, running your fingers over the keys to aid the process.
If you have stuck keys or a very dirty keyboard (due to spilled drinks, for example), you can also remove the individual keys and wipe beneath them with a cotton swab dipped in the cleaning solution. Be sure you check your laptop manual to make sure the keys can be removed for cleaning, and, of course, put them back the right way.
Some laptops have drains built into the keyboard tray. If yours is like that, you can pour distilled water into the keyboard and let it air-dry. Check your manual to be sure.
Finally, use the damp cloth to wipe the keys and the touchpad.
Clean the Ports and Cooling Vents
Use the can of compressed air to clean the case openings: the ports and cooling vents. Spray from an angle so the debris is blown away from the computer, rather than into it.
Also, be careful when spraying the fans, because if you spray too hard liquid may get in the fan blades. To prevent the fans from over spinning while you're blowing the air on them (which can damage the fans), place a cotton swab or toothpick between the fan blades to hold them in place.
Last But Not Least
Make sure your laptop is completely dry before turning it on.
