I've recently installed OpenWRT 21.02 RC3 on my TP-LINK Archer C6v2 but I'(m having lots of issues with my wifi signal (both 2.4 & 5 ghz). Wifi connection is dropping constantly.
I want to look if 19.07 is running more stable. How can I swith to this version? Is it as simple as goint to system -> flash new firmware image & uploading the 19.07 'sysupgrade" img, or would that break things?
Just make sure you don't keep the configurations when flashing from one major release to the other. Most likely there will be configuration options in 21.02 which will not be compatible with 19.07 and might have unpredicted behaviour.
I saw your message too late
I've flashed 19.07 keeping the configuration but now I cannot access my wifi router anymore: I can't find it on the network (not on the old ip, not on the default ip 192.168.1.1). I still have internet connect with the cable (DHCP, DNS.. is configured on my other router)
What can I do to make my router visible again please? Is there a way to reset?
