Interesting Wifi issue
-
Hi All,
It's been a while and I just did a clean install to the newest Retropie image (4.6 on Buster) as I was still running on Jessie. I've got a a supported Tenda Pico wifi adapter installed on my Pi 3. It's working, but just not quite as well as I'd hope.
My wireless network is a single SSID consisting of both 2.4 and 5ghz frequencies. When I setup wifi on this new install, I disabled the onboard wifi via /boot/config using "dtoverlay=pi3-disable-wifi". Now only the Tenda adapter is active and is listed as interface wlan0.
When I connect to wifi, I see two SSIDs for my network, even though only one is present. I can connect to both and everything works as expected. However, regardless of which of the SSIDs I connect to, when I check iwlist wlan0 frequency the only frequencies are in 2.4ghz and I know this adapter supports 5ghz.
This all leads me to my question - is there a way I can force the adapter to connect at 5ghz or something I can do to troubleshoot this further without changing mySSID configuration?
Thanks!

Well poop. The adapter DOESN'T support 5ghz. I guess it has been longer than I thought since my last update. Time to buy another Pi!
