I have installed (l)ubuntu 20.4 on a HP 250 G3 laptop.
Since the internal WLAN adapter (RT3290LE) has also problems in Windows, I am installed a USB WLAN adapter with RTL8188EUS. I believe that I have disabled the internal RT3290LE WLAN adapter, but I am not sure about it. How does one check this out?.
The signal strength with is great now, but at the moment I am losing connection every 1 to 5 minutes. It reconnects and it is possible to work with works, but is it quite annoying.
Similar issues were all for older versions of ubuntu and usually called for updating the WLAN driver. I imagine that the new driver was in the lubuntu distribution, so I don't think this will be the problem. I also switched off IV6 in the nm-manager (ignore). I also saw something about preventing the system from turning off the adapter to save energy, but I could not find anything particular for the RTL8188 adapter.
From what I have read, maybe this information is helpful:

Where to go from here?
