No Network after installation of 20.4.1


I just newly installed lubunt 20.4.1 on a HP 250 G3 next to windows 10.
The initial USB boot for the installation has problems with the WLAN,
but from what I have read this is due to the RT3290 chip which is in this
laptop and I would like to get to this after the wired LAN is working.

While the wired LAN worked from the USB boot, I can get no connection
to the wired LAN now when booting from the new HD installation. When I boot
windows 10, the LAN connection works fine, so it seems to be a lubuntu
issue. The driver in windows is Realtek PCIe FE Ethernet Family Controller.

Sudo lshw -C network gives:

I have some notions about linux, but the network stuff is really confusing
and I am not sure where to start.

Any help is appreciated.


The wired LAN now has a connection. Honestly, I don’t know why, but the conneciton is available now. While I am happy that it is working, because I can now work on the WLAN topic, I always feel a little bit uneasy, because I don’t know what the cause or the fix was, so of course the fear that it might suddely stop working is there.

Could it be possible that the nework services work in the background an an attempt to make a connection somehow?


I’ve never had cause to try it, but your drivers should be on this page:

I checked and you’ll need to enter an email address (doesn’t seem to need to be valid) and then the download will start. Inside, there are some files but there’s a readme that has the directions to follow. It looks fairly straightforward.

Hello KGIII,

thanks for the link. I’ve downloaded and will give it a try :slight_smile:


It’s a bit late here, but I figured I’d check back in and see if you got everything squared away? If not, someone here will (probably) know how to resolve any additional troubles you may have.
