Hello,

I'm the proud new owner of a set of Orbi triplets, running the latest Voxel. I was wondering if anyone had any insight or suggestions in order to successfully change the backhaul channel while retaining it's HT80 settings.

I previously had a r7800 but the house I'm now living in is a 4 floor row home in a dense neighborhood, with a condo building on one side of me.. so I had to switch to something with more coverage.

I currently have them setup in a star configuration, connected to a 1GB FIOS connection. Implicit BF is off, MU-MIMO is off, channel coexistence is on, Daisy-chain is off.

I have a lot of channel interference from the neighboring Condo building which seemed to be causing lower throughput, but more importantly, spikes in latency while connected to 5G.

I managed to force the frequency to switch to 56 (DFS) by using the wla_channel and wla_hidden_channel nvram variables, and was successful. I saw increased performance and reduced or non-existent latency spikes when connected directly to the router. The problem is the backhaul, I got it to switch to 140 (DFS) but the channel width would only stay at 20MHz. I tried setting hwmode to ac11, htmode to HT80, and enabled enhance_dfs but it wouldn't budge.
