@Pope What software do you currently have? I have 1.3.7 beta and I'm waiting for new ones. The good old non-beta software is 1.2.1 for me. If nothing new comes out soon I will come back to it again....

Check out 1.3.7 Beta. Up to 1.2.1 the wifi worked fine, then only in Beta. I lost link to 1.3.7, you have to search on forum. I had much bigger problems with wifi at 5ghz

@noseran I don't know what could be wrong, did you turn off the firewall ..? https://static.tp-link.com/2020/202001/20200123/Archer%20C6(EU)_V2_020110.zip

@noseran Where I read, they recommend the switch, if it does not work now, try it. I always went back to 1.2.1. I doubt they will make a mesh switch. I wrote a few months ago with a senior engineer...

Factory Reset? Online update via router options? If everything works, it might be better not to update, sometimes there are more problems than the benefits of newer software.
