I'm having some wifi Issues with Bullseye / BrosTrend AC1200 / Le Potato 1gb.
I figure my problem is more related to Raspberry OS / my adapter than my board, but I could totally be wrong here.
Here's where things are at
Flashed a clean/uncompressed RPI OS 11 Bullseye from Libre's website onto SD as per the guide
During setup, I forgot that I had a cheap wifi adapter plugged into my Le Pot / no ethernet. The Pi OS setup spotted my SSID out of the box with that cheap adapter, I tried to connect, but it failed to connect. I chalked it up to the crappy adapter, plugged in my ethernet, and unplugged the adapter. The only reason I mention it is maybe some weird config things happened here.
I continued setup, got to the desktop, chromium installed, and bam I'm browsing the internet with zero problems on ethernet.
I then plug in my BrosTrend AC1200 (AC1L) adapter, unplug the ethernet, and find my adapter is not immediately recognized out of the box.
Ethernet back in, download the drivers via their official guide, namely:
sh -c 'wget deb.trendtechcn.com/install -O /tmp/install && sh /tmp/install'
Rebooted, took out ethernet. Sure enough, the wifi can scan for SSIDs and connect to my SSID.
The Problem However, here is the problem: without fail my pi will stop communicating ALL network traffic within minutes. When I try to ping 18.104.22.168 or even any local devices on my network, I only receive Destination Host Unreachable. I've searched the common options such as
making sure wifi power management is off (it is)
double-checking I'm not forcing a static IP in /etc/dhcpcd.conf
alternatively have tried forcing a static IP
changing my nameservers from my router IP to 22.214.171.124 in resolv.conf
tried alternatives such as network-manager
tried using a powered USB hub
checked in my router's list to ensure IP is accurate and given via dhcp
added freq_list to limit to 2.4ghz in wpa_supplicant.conf (unsure if this is working, I read some reports that the pi (and maybe, therefore, a potato) didn't like 5ghz band)
this is required because I use a google wifi router (just one, no mesh) with a combined 2.4/5ghz. Additionally, I'm working on an IOT concept device that would need to be plug and play with any network
I've also heard that setting your Wifi Country to something like Israel or China can force it to not scan for 5ghz wifi? Haven't tried that
Wifi country is set to US in wpa_supplicant and looks identical to ones I've seen on other posts as far as "what is correct"
None of these have solved it. With ethernet in, I'm steady as she goes.. But on the wifi card, it displays as connected in the UI but I only receive Destination Host Unreachable when pinging anything.

Please let me know if you have any ideas of what could be going on here.
I'm happy to dump copies of .confs or whatever if you have any suggestions as far as where to look next!
