Interference from other wireless networks in the area can cause issues with your wireless signal. To determine whether interference is occurring, you can use an app like Wi-Fi Analyzer for Android. It will show you the wireless channels nearby networks are using and recommend the ideal network for you to use — one that isn’t being used by as many networks. This app will also allow you to walk around the area and see where you get the best signal and where the signal is weakest – you can do this with any other device, too.

If multiple wireless networks are competing for the same channel, this can cause problems. To fix this, you can change the wireless channel in your router’s web interface. You can do this even if you don’t have access to a wireless-analyzing app – change the signal to a different channel and then see if your wireless connection improves.
