Can't access internet after wireguard uninstall

Hello,

I had a working wireguard peer on my laptop, which I didn't want anymore, so I decided to uninstall wireguard. All was well until I restarted the laptop and now I can't access the internet anymore.

I think it's because of some config left over from wireguard, but I'm not sure how to fix it.

Running pop os 22.04.

Any advice?

~~Nope. Destination host is unreachable when pinging~~

I changed to a different router and can at least ping that now, but still no internet

So that looks similar to what I have. Wonder why it's not working

Did you try to ping the router IP, 192.168.1.1 and see if it responded?

@anytimesoon With that different router, now try a traceroute 1.1.1.1, if you get a response from the first hop, 192.168.1.1, then something is wrong with the NAT on the router or your cable service or fiber or whatever it is, is not working.

Unlikely to be something wrong with that, tbh. Everything else on that network has internet access. The issue is limited to the laptop

@anytimesoon I'm a bit at a loss then. I do have a Comcast router that is weird in that ARP only works at boot time so if I plug a new device into it, it won't route for that device unless I reboot it.

No worries. Thanks for your help! I'll post here if/when I find a solution

Hi

Did you remove wireguard the meta package or everything wireguard installed? I don't know Pop but other distros install additional tools and configs like wireguard-dkms.

Also, if possible, after completely purging every wg you could try booting into a previous kernel on your system to see if that changes anything.
