I check with a different tool but it should be the same in LuCI
nobody uses DFS, I don't think anybody is changes any router settings around here except me
why does Local interface show as 80MHz but the main AP show as 20MHz
there is nothing on that channel except me
Because the main AP needs to be manually changed to a width of 80 (it sets width, client just does what it is told unless told a smaller width than AP.; little wonder you are getting bad throughput with 20..
its only showing in openwrt as 20MHz, it is 100% using using 80MHz
I can't go much higher anyway, 128 is the limit and anything above 100 takes 10 minutes to apply
It just makes things cleaner and sometimes fixes things.
Then use Wi-Fi analyzer from Android and stand about 1 yard from the PI. Use landscape view (otherwise it is hard do read) and make sure it is set to 5GHz.
Save configurations on both the Cox router and the Pi router; after that you can play around (especially with channel selections) but don't add any packages.
I'd reboot the Ap and then the Pi and test again; channel analyzer is not, usually, that inaccurate.
You get home just as I need to go to sleep, so I'll catch up tomorrow.
You have been told numerous times that connecting two devices through WiFi using DFS channels is a bad idea, yet you continue to do this practice. And then complain when your link goes down at random.
In my opinion, the suggestions given to you in your other posts still apply even now.
It won't take the change in OpenWrt.
Boot to Rasp OS
Choose your country; your choice will be persistently what you choose on all radios..
Now you should be allowed to pick Auto in channel selection and a CCC should pick a clean place to park; if it detects a possible issue later it will warn clients its intent to move to what it decides is a clear channel then change channels and reestablish connections. This should not take more that 13 minutes the first scan.
Run another speedtest and say a little prayer.
Sorry but I don't get how any of that is going to help
before when I have used rasp os, it had the country code set
the country code has been set within openwrt
what causes 5GHz interference because the main AP(RE450) seems to have low download speed again but upload is fine
I had heard HDMI can on raspberry Pi's, but what else
Could I have 2 STA connections to the relayd bridge to increase throughput
