I have 4 ASUS routers in a Mesh setup, and additional TP-Link routers at the periphery of my home network. The ASUS devices must all be on the same channel, which each TP-Link device lets me choose a channel. I had been achieving Speed Test results on my iPhone 14 in the 600-700 range, but this seems to have dropped to 400 max (1 gig fiber, wired gets to 900+ consistently). And one of my users reports his video calls are suffering drops. I am guessing that I have WiFi collisions causing issues. Its all a difficult problem for me because to get good 5gHz speeds, I need the routers closer than I might otherwise like them. I have the ASUS at channel 100 and the TP-link at lower channels. But I am not sure what is ideal. Most clients will connect to the ASUS. Is it better to use higher or lower channels than 100? I am on the woods so no interference from neighbors etc.
