Hello, I am running ubuntu 20.04 on an MSI GS66 Stealth, running kernel 5.9.10-050910-generic #202011221708 SMP Sun Nov 22 18:07:21 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

I was playing around with libpcsc and somehow accidentally deleted the network manager.. Fortunately, I was able to get it back by connecting to ethernet with
Code:
sudo dhclient eth0
, and then
Code:
sudo apt install network-manager
This brought back my wifi to some degree--it now detects networks and is able to connect to my wifi network. However, I am not able to access any websites. The internet is working normally on ethernet, it's just the wifi that isn't working.

Any ideas how to get it back?

Code:
ifconfig -a

Notably, my wifi settings is set to Automatic (DHCP) under IPv4, while the ethernet is set to a manual static IP of 192.168.1.5 (something that I had left over from a previous project). I've tried changing back to Automatic (DHCP) for ethernet, but the change doesn't take for some reason.
