I have a Dell Vostro 5590 with Intel 9560 NGW network chipset.
I had a problem where my WiFi card wasn't being recognized by Elementary OS Hera (5.1), used this question in order to get it recognized (installing the
backport-iwlwifi-dkms as adviced). However, now I have two issues:
- I have a low bandwidth, since the connection itself is poor, and I get errors loading pages.
- I cannot connect an external WiFi card, which I could have done before.
Since it is already running Kernel Version higher than 5.3 (
5.4.0-45-generic), the kernel issue doesn't seems to be the problem.
The computer itself shipped with OEM Ubuntu 18.04, and it worked fine with that and Kubuntu 18.04. I had no bandwidth issues with the built-in chipset on these.
