A manual scan using a free app like NetSpot reveals actual congestion across 2.4 GHz, 5 GHz, and 6 GHz bands. For 2.4 GHz, stick to non-overlapping channels 1, 6, or 11 and limit width to 20 MHz. For 5 GHz, channels 36–48 are broadly compatible but congested; 149–165 offer higher power with less interference; DFS channels (52–144) should be avoided at home. For 6 GHz, use the Preferred Scanning Channels and assign different channels to each mesh node. Manual selection isn't a guaranteed fix but is a practical first step in network troubleshooting. ## Full article daily.dev links to this article rather than hosting it.
