How to change your WiFi channel to reduce interference
WiFi channels are like radio frequencies. If your neighbor is using the same channel, you get interference and slow speeds. Use a WiFi scanner app to see what channels your neighbors are using, then pick an empty one. Go to your router settings, change the channel, and save.
Your WiFi router broadcasts on a specific channel, like a radio station. If your neighbors' routers are on the same channel, the signals interfere and your WiFi slows down. The solution is simple: pick a different channel that nobody nearby is using. The best channels to use are 1, 6, or 11 on older WiFi networks, or a wider range on newer WiFi 6 routers.

Skip — I just want a technicianCommon mistakes to avoid
- Picking a channel that overlaps with a neighbor's. Channels 1, 6, and 11 don't overlap, but anything in between does
- Not waiting long enough after changing channels. WiFi needs about 30 seconds to fully reconnect
- Forgetting to click 'Save' or 'Apply'. If you don't save, the change doesn't stick
- Assuming 'Auto' is the best option. In crowded areas, manually picking a quiet channel is better
Signs you need professional help
