I have just flash openwrt latest version on my tplink c6 v3 but when i get like 15 meters away the 5ghz download speed drops but the upload speed remains good. I have tried doing it for 3-5 times but same results.
Is there any fix for this? The download speed drops really fast but when i am close the speed it's completely fine
Is there any fix for this? (It was completely fine on stock firmware)
You need to set up country codes for all radios.
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
Yes i have set up country code on my router
ubus call system board

Set country on 2.4GHz radio and remove noscan option.
The behaviour looks like NSS1 and consequential beamform fail fixed here
i.e downgrade to 23.05.3 or upgrade to 23.05-SNAPSHOT (not the master SNAPSHOT from firmware -selector, but one on download server)
Just downgrading is going to fix it huh and does the snapshot version has gui?
And how to remove noscan option?
Check the label, whether it is A6 or C6
It is c6 v3
I have downgraded it
Now how to remove no scan option?
Checkbox is cal\ed "force 40MHz"
How to know if beamforming is actually working on on router?
If you see NSS:2 near end of status page (this is defect - NSS1 from AP to client)
Isn't that different than beamfroming?
Beamforming is the ripple beams forming effect when you drop 2 stones in the water, cant happen with one.
Well it shows 2
You can find hostapd config files in /var/run, it is there under capabilities.
It says signal quite average.
As per wiki page - this device does not support radar detection, so you are restricted to usually crowded non-dfs channels. You can try automatic channel, it gets kind of least used, but not guaranteed to be better.
Well it somehow is getting worse range than stock firmware that's the thing but i ain't going to use stock firmware cause that thing is missing a lot of things anyways you actually helped to fix the range enough that I can use it
Yes, this is one of devices with serious limitations. Your speed is limited by weak radio reception. If you want to max wired performance you have to enable firewall offloads, and to have best (still not ideal) wifi coverage set up identical access points in both bands.
