5ghz auto changes channel

I been having issues with my router changing the 5ghz channel from 40 to another channel like 149 or 161. This is happening on a RAX50 router and there is no option for auto channel for 5ghz, only 2.4ghz. I want to keep the channel at 40 because it is the least congested channel around me and the other channels makes wifi signal weak in some areas in my home.

Does anyone know why this is happening and what can I do to fix it? I don't have it on a DFS channel and I can't find anything else to fix it.

Thanks!

  • How big is the home? 

    Maybe look into getting a wifi extender for help in coverage in the weak areas of the home. EAX series should be checked into. 

  • The RAX50 is a 4x4 with 160hz wide channels. To use 160hz wide channels, its uses the dfs channels. You can disable that option by going in and setting your speed from "up to 4800mbps" down to 2400mbps". That narrows the broadcast to 80hz wide channels and then it avoids those dfs channels. For the most part, it won't impact many devices as many devices didn't use 160hz wide channels until you started getting to higher end or newer Wifi 7 devices.
