5GHz Wifi AP does not show up (TL WDR4300)

Installing and Using OpenWrt
1

I've read all the posts on this issue and can't find an answer.

The 5GHz simply does not show up on clients. But the 2GHz does, no issues.

I've searched online and here, no luck.

I'm running: OpenWrt 22.03.2 r19803-9a599fee93

Thanks and I appreciate your help.

What channel do you have set on the 5g radio and what country code?

Thanks a lot @Peter!

I would suggest to rm /etc/config/wireless and run wifi config, reboot to start with a new default (wireless-) config again. Start out simple (country-code=DE, WPA2PSK/CCMP, PSK2 without fancy control characters). The reason I'm mentioning this, is because I seem to remember that radio0 might be the 5 GHz radio (and radio1 2.4 GHz), but I don't have my tl-wdr4300 online (or even unpacked) right now to check.

@slh @psherman what I discovered is that the network, the 5GHz, shows up on an iPad, but not on any of Apple's macbook pros. This is rather interesting. I did not try connecting to it, but will do and report back. I think the 'showing' up is interesting, as is.

Which generation? Pretty much anything modern should have no issue, but we can start with verifying that the versions you're talking about are indeed 802.11n (5G) or 802.11ac enabled.

@psherman Hi, Peter, for example: MacBook Pro (15-inch, Late 2011) 2,4 GHz Quad-Core Intel Core i7.

That one has 5G support, although it is only 802.11n (so is your router, though, so that is neither here nor there).

Did you follow @slh's advice to regenerate the wireless config file?
