Hello @mihai_balaci,
Please start here:
1 - Create a new 5GHZ radio profile and don't use the default one
2 - Disable client access on this radio for now and only enable backhaul
3 - Configure the channel manually on both APs (as an override) selecting channel 149 and above
4 - Enable OFDMA in both directions
5 - Enable DFS channels and change channel width to 40MHz
6 - Disable Frame burst
7 - Make sure you have line of sight between the 2 APs and no obstacles at all
8 - Make sure that both APs are on the same firmware version
Run this command on both APs: #show acsp neighbor
You should see the Backhaul neighbor with the VHM name, check the RSSI to see how low it is.
Test to see if this improves throughput,
BR,
Christoph S.
