I recently happened to write the uConsole_CM4_v1.3g_64bit.img.7z image to a microSD card and performed the initial update, but after that, the Wi-Fi settings could no longer be configured via the GUI. So I’m sharing the solution here in case it helps someone.
Then, right-click on the top panel and select “Panel Preferences” → “Items” → click “Add” → select “Wireless & Wired Network” and click “Add”.
I tried using network-manager (sudo apt install network-manager), but for some reason, I couldn’t tether with my iPhone 15 using that method. With dhcpcd, however, the connection worked perfectly with the iPhone 15.
