How To Troubleshoot Your Wireless Router (Wi-Fi) Tutorial

Are you having any problems with your internet connection or Wi-Fi? Whatever the problem – a poor connection, flaws in Wi-Fi, or even no Internet access – these tips for locating and troubleshooting your router should help.

Some of these tips also apply to your modem, although many Internet service providers are already offering an integrated router & modem combination these days. Your wireless router and modem may actually be the same device.

Restart the Router

Have you tried restarting it? Yes, again, rebooting is the solution to many network problems. In cases like: websites that are loading with failure, everything that is related to the network seems slow, connections falling, or your wireless signal is weak; in these cases, try first of all simply restart your router.

This should not be necessary, but most routers seem to need an occasional reboot to keep themselves running fine. Restarting is very simple on most routers – unplug the power cable from your router, wait a few seconds, and then plug it back in. If you have a separate modem, you can also try to unplug the power cable from your modem and reconnect it after a few seconds. Some devices may have a power switch, but the power disconnect and reconnect method work on all routers.

If you have to restart your router very often, the manufacturer’s firmware may simply be unstable and flawed. In this case, try installing an alternate firmware such as DD-WRT.

Check for Overheating

Like any other electronic device, routers can also overheat. This overheating can damage the router over time or simply make it unstable. Check the temperature of your router to see how hot it is. If it looks too hot, make sure it is getting enough air circulation. If the ventilation holes are blocked or you leave your router in a warm place – such as on top of a computer tower where the temperature is highest – overheating may be the cause of the instability. It is also very likely that previous overheating may have caused damage to the router.

Check that All Cables Are Well Connected

This may sound crazy, but sometimes we forget to check the most obvious solution before moving on to the more complicated ones. Someone may have accidentally stumbled or tripped on a cable, causing it to disconnect or to break. You should check all the cables involved and make sure they are connected securely.

Be sure to check the power cables of your router and modem, the cable connecting your router to the modem, the cable between your modem and the wall plug, and each Ethernet cable connected to the back of the router. Check each end of the cable and make sure it is securely connected – it may look connected but may be a little loose.

Reposition the Router

If you are having problems with your Wi-Fi signal, you can try resetting the router. Make sure nothing is blocking the wireless signal, especially large metal objects or interfering devices such as microwaves and some types of cordless phones.

You should also ensure that the router’s antenna is positioned vertically rather than horizontally – a vertical antenna will provide you with a larger coverage area.

Change the Wireless Channel

If you are in a location that has a lot of wireless routers nearby, such as an apartment, chances are great that your router is subject to interference from other wireless routers sending signals at the same frequency as yours. Determining the most appropriate Wireless channel for your area and adjusting your router to operate on that channel instead of a more congested one can reduce this interference by improving your wireless signal.

If you have an Android device, the Wi-Fi Analyzer application can help you analyze your area and find the best channel. After that, you can change the Wireless channel in the settings of your router.

Reset Your Router To Factory Default Settings

You can try resetting your router to its factory default settings if there appears to be a serious problem with your configuration. This should not be necessary in most cases, but this is a good option if you are already exhausted all your attempts. It is possible that you have changed certain settings on your router that you should not and it may be easier to revert to a clean state than leaving by changing the back options one by one.

Keep in mind that you will have to reconfigure your router afterwards, including reconfiguring the name of your wireless network and passwords. You will probably have to press and hold the “Reset” button, located inside a small hole behind the router, using a pin or similar (fine enough) to reset (reset) your settings, but the exact details will vary from router to router. This is the same process you have to do to reset / reset your router’s access password.

Other Possible Problems

Like any process of detecting and solving problems, there are virtually endless things that could go wrong: – Your router or modem may be broken; The Ethernet cables you use may be damaged and require replacement; If only one device you own is having problems with your network connection, it may have a software problem and you may need to have to troubleshoot specific device issues – or maybe just restart it if you’re lucky.
