PC Connects to Wi-Fi, But Only Has Internet Over Ethernet

My System Info

Linux Distribution: Pop!_OS 22.04 LTS
Desktop Environment: GNOME 42.9
Graphics Card: Mesa Intel HD Graphics 4000 (IVB GT2)
GPU Driver Version: i915

Have you checked for system updates?: Yes

If this is not Steam, you can still give us a system readout using inxi with "inxi -SbCGxx" in terminal (please put that into Pastebin/Gist as linked above!):

You can note your issue below here

My second computer, a Sony VAIO Tap 20 SVJ20215CB "sees" and connects to our Wi-Fi network, but it doesn't actually have Internet connectivity. No other device in our household, including other Linux-based laptops, have this issue. This particular computer also has perfect connectivity (i.e. no issues) when connected ti my modem / router by ethernet.

I thought it was something related to the modem / router I was previously using, but I just changed to Starlink and it is the same issue with the new modem / router. Again, no other device in the household, including other Linux-based laptops, have issues, suggesting the problem is unique to this computer.

Obviously I can leave it connected by ethernet, and that is my "Plan B", but it would not be ideal.

Any ideas?

Try updating your wifi card driver separately.

Edit:
how to do that:
lspci -vq
look for the one with wireless in the name
post the name and kernel-module here
sudo apt install -only-module [kernel-module]

Output of ip addr and ip route might be helpful.

Could be poor driver support for your Wi-Fi chipset.

I have this problem with my Lenovo ThinkPad T440p laptop as well. Like you, the Internet is rock-solid on Ethernet but completely unreliable/unstable on Wi-Fi. I traced the problem to poor driver support for the Intel Wireless-N 7260 chipset.

This problem was present regardless of the distro. I'm currently on Pop!_OS like you. Prior to that, I was on Manjaro. Interestingly enough, Manjaro seemed to have stabilized the driver over time but, initially, the Wi-Fi was just as unstable as on Pop!_OS. Ironically, the Wi-Fi driver is rock-solid in Windows 10.

Unfortunately, I never did resolve the issue in Pop!_OS. The problem with the Intel Wireless-N 7260 Linux driver is a notorious one all over the web. I gave up and I just use the Ethernet connection instead.

Edit: Verified chipset model.
