Check before changing
Use your router app or admin page to see current channel and band. Make one change at a time so you can tell whether it helped.
Use automatic settings carefully
Auto channel selection is often fine, but crowded homes may benefit from manually testing a cleaner channel.
Restart and retest
After changing settings, reconnect the devices that had problems and compare results in the same rooms as before.
Before you buy or book anything
- Record which rooms and devices are affected.
- Test with one known-good cable or one known-good location.
- Keep affiliate buying decisions separate from basic troubleshooting.
