Placing it in a more central location can ensure that all devices fall within its signal range. Of course, one simple solution might be to simply move the entire router. That may be the right solution if it lets you get WiFi to where you need it, while taking it away from places you don’t. Rotating them and pointing them in particular directions also changes the shape of the WiFi “bubble”, which might help eliminate dead spots. If you have external antennas on your router, you might want to try adjusting them. That should significantly improve range and signal strength. This is usually called Tx power or something similar, but varies from model to model. Within your router settings there should be one related to the transmission power of the signal. You may also be able to set the device to the 2.4Ghz band in its own settings, ensuring that it only connects to the stronger signal, without affecting anything else. If that’s the case, make sure that the devices that are having trouble picking up the 5Ghz band connect to the right one. Many dual-band routers actually offer two separate WiFi SSIDs – one for each band. So if forcing the 2.4Ghz band turns out to work, you’ll want to do one of several things. Of course, we don’t want to use the slow band for everything. If it does, it might be a question of distance or simply material that blocks the 5Ghz band between the device and your router.
However, you can try switching your router to using the 2.4Ghz band only, to see if that improves your poor signal strength. Usually the device and router will automatically manage which band is best. The 2.4Ghz band is slower, but has better range. Many modern routers are “dual-band” and will operate at 2.4Ghz and 5Ghz.
If it was already set to a specific channel, you might want to change that setting to automatic instead. Then log into your router’s interface via a browser and change its channel setting to one no one else is using. Use an app like WiFi Analyzer to check which channels other WiFi routers in your location are using. For example, your neighbour’s new router could be set to the same one yours is using. Usually modern routers will pick a channel that’s clear, but it could happen that you’re experiencing a conflict. WiFi is separated into distinct channels, which allows two devices on the same band to operate without interfering with each other.
