Problems with Wi-Fi

Although several improvements have been made recently to Internet speed and Wi-Fi, you may still encounter slow internet speeds and connection problems with the Wi-Fi. This is due to the fact that Wi-Fi operates in unregulated portions of the radio spectrum and Wi-Fi networks currently operate like a “a weak radio station in a busy city market” when trying to tune in. To efficiently tune in and get online, here a few pointers to help solve those Wi-Fi problems:

  1. Try Rebooting the Routers

  2. This may be the simplest solution to your Wi-Fi issues. Just try unplugging the power cord, wait a few seconds and then reconnect, if there are multiple routers or wireless access points(WAPs), reboot them all. Consumer or cheap Wi-Fi gear may need to be rebooted every few weeks to ensure that it works effectively. You can also turn the Wi-Fi off and on again on the computer as it would force the system to rescan for available networks.

  3. You Can Also Change the Location of The Routers and Computers

  4. Just changing the location to just some meters away can make a big difference. Try a higher and more central location. You should keep the router away from large metal surfaces as these act as energy sinks and obstruct Wi-Fi signals. Also, keep the router away from mirrors and other reflective surfaces as these also affect Wi-Fi signals.

  5. Watch for Overheating

  6. It is important that the vents of the router are not blocked by any other equipment placed on top of it. The router already possesses a poorly ventilated box and not keeping these vents open may result in strange behavior from the router.

  7. Updating the Firmware

  8. Firmware updates are often done to improve performance. You should always check if the firmware is up to date if you run into problems. You can also apply available patches especially when using new devices. But be warned! Firmware updates may introduce bugs into the system, so only update the firmware when you run into problems.

  9. Use A Larger or External Antenna

  10. Wi-Fi antennas are typically a few centimeters long on the router and internal on your device. If you are having problems with reception, you can always use a larger or external antenna. Some routers may offer removable antennas which should be easy to buy and replace. An external antenna can help to boost the noise to signal on a desktop or laptop with a metal case. You can also create a parabolic dish antenna by using a vegetable strainer and work accessories.

  11. Forget Previously Saved Networks

  12. Sometimes computers and mobile devices may run into problems even if they are connected to previous networks. The password may be the same but network hardware or encryption methods may change. The best way to resolve this matter is to let your device forget a previously saved network. It acts as a sort of refresh for your device. Once this is done, if you need to reconnect, you most definitely can!

  13. Change the Wi-Fi channel

  14. Signal connection may be a problem especially if you live in quite a populated are as many devices use both 2.4 GHz and 5.8GHz bands. You can try changing the broadcast channel of the router. You can try running your router in automatic mode which will easily assign a clear channel. If you are still encountering problems, try using a Wi-Fi monitor so that you can see what channels are being used and be able to choose a channel that’s much less crowded.
    Try changing encryption methods by using another encryption method. Some of these methods are WEP, WPA, WPA2. Your password encrypts transmitted traffic so you can change the encryption method and see what works best. Try using WPA as it is a huge improvement from using WEP. WPA encryption may not be supported by older 802.11b equipment, so stick to WEP.
