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.
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.
- ✓Download a WiFi scanner app on your phone to see what channels nearby routers are using
- ✓Make sure your router is set to 'Auto' channel, or you've manually picked one before
- ✓Note which channels are empty and available in your area

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
- You can't log into your router — the default password has been changed or reset to factory settings. You changed channels but speeds got worse instead of better — we can help you try other channels. Speeds are still slow even on empty channels — the problem is your internet plan, not WiFi interference.
