Netgear R6260 - OpenWrt 23.05.0 r23497-6637af95aa / LuCI openwrt-23.05 branch git-23.292.78378-27fb6e5
I have two issues after resetting the router and installing new instance of 23.05 from previous version. I use DFS channel for 5GHz, as Airwaves are crowded. (49 APs !!)
A: I never had issues in the past with Channel 100 or 120. Now the connection just drops randomly. I have to restart the interface to make it work.
B: /luci/admin/status/channel_analysis in 5GHz section is unreliable. It sometimes just shows local Interface or the neighborhood channels but not my local interface with neighborhood channels. The list below does not show the local interface too. In addition, the screen does not scale properly. This could be because my channel is not showing up. 2.4 GHz section does work properly showing everything correctly .
