You can note your issue below here
My computer can successfully connect to my Wi-Fi (wireless) network using the correct password, but when I try to access anything online (websites, updates, etc...), I am told that the computer cannot connect to the Internet.
This issue occurs even when within one meter (3.2 feet) of my modem / router.
No other devices have connectivity issues with this particular Wi-Fi (wireless) network, even devices physically further away and / or devices close to things that will likely cause interference.
This issue does not occur when connecting via ethernet (physical connection).
This issue is intermittent when using my Apple iPhone 12 Pro Max as a "hotspot"; though it generally leans towards being unable to connect to the Internet (probably 99% of the time). My cellular network has ample 4G / LTE coverage in the area, and limited 5G NR coverage (besides, here in Australia, our cellular network is far superior to our fixed broadband network - which is why my wife and children primarily use that for all of their Internet connections at home!).
I do not have my VPN running (it's not even logged-in yet, because I am not able to go online), and this issue persists regardless of whether my firewall (ufw) is activated or not.
With the exception of my VPN - which is installed, but has not been configured, is not logged-in and has never been used on this particular computer - this is a "clean" system (i.e. it just had a "fresh" installation of Pop!_OS)... All of the available updates or upgrades for a "fresh" installation of Pop!_OS have been installed at the time of writing.

Can you try with a different wifi card?
Also, with the card you already have, have you looked at the system log for any errors related to wifi? Especially firmware errors?

It's one of those stupid "all in one" things. It seemed like a good idea at the time. 🤦♂️
From memory, I think the Wi-Fi card might be a RAM-like "plug-in" module though... Not designed to be replaceable or anything like that, but accessible (the guts of this computer is basically the same as a laptop, slapped onto the back of a giant touchscreen, complete with a battery); so I'll check the seating of the Wi-Fi module in the morning.
I honestly don't think that will be the problem though, because this computer maintains a consistent - and strong - connection to my Wi-Fi network... It just can't connect to the Internet itself.
Were the Wi-Fi module itself the issue, I would expect to see a weak Wi-Fi signal or more likely, complete loss of signal. That's not the case here.
But it never hurts to check, just to rule it out...
This is a good idea, but in what directory do I actually find the system log? I'm not using the affected computer at the moment, but I can see an awful lot of logs on my "primary" computer, so I imagine it will be the same on the affected computer...

* I don't think the card would be enabled or connect if firmware wasn't loaded. But I could be wrong. There's usually messages in dmesg (the kernel log) for firmware.
* There are some odd issues with iwlwifi and a few options to try:
https://wiki.gentoo.org/wiki/Iwlwifi#No_internet_connection
* if the VPN stuff is something not bundled with your distro I guess it's possible for it to screw something up by just being installed, but probably unlikely.
* You don't have to remove/replace the built-in WiFi card. Trying a WiFi USB dongle would help to figure out if the problem is with the iwlwifi driver/hardware or something else. Another option is to try a live USB of another distro to rule out broken hardware.

For network logs something like
sudo journalctl -f -u NetworkManagerbefore connecting to the router should hopefully give some clues. (Assuming PopOS uses NetworkManager?)Also, checking and comparing network settings between the wired and the wifi, using something like
ip routemight be useful.Last edited by whizse on 16 March 2022 at 2:19 pm UTC
I'm not saying you should replace the built-in card, just connect one through USB if you can and see if there's connectivity then.

I don't have one of those... I know they're out there, but the last time I even saw something like that was probably 20 years ago (or close to it), because pretty much everything since then has had Wi-Fi built-in or an ethernet (physical) connection port.
Here's the output:

-Try out a different distribution in Live mode.
-Try out a different router if possible.
-Try a different wireless network from your own (e.g. library, café, ...).
The above things can help you find the root cause.
Do you have working DNS? What does
cat /etc/resolv.confsay? (After connecting the WiFi, Ethernet unplugged).Can you ping the router? E.g.
ping 192.168.20.1(or Google, 8.8.8.8 or Cloudflare 1.1.1.1?)Anything interesting concerning iwlwifi or NetworkManager in the more general logs like dmesg or journalctl?
(Apologies if this sounds like a wild goose chase. I'm trying to thing of things I would try under similar circumstances, and it is very much a throw everything on the wall and see what sticks kind of approach!)

I think this is the issue.

So I tried Manjaro with KDE Plasma, 21.2.4, Fedora 35 and Ubuntu 21.10... All three were able to connect to the Internet, without issue when running in "live" mode.
Interestingly, Ubuntu 21.10 is what Pop!_OS 21.10 is based on and to the best of my knowledge, they use the same network stuff (i.e. anything relating to the networking is the same for both distros)...
Clearly the issue is a software issue, considering the above distros were able to connect just fine in "live" mode.
Yeah, I tried using my iPhone as a "hotspot" with mobile data (i.e. Wi-Fi turned off)... Same issue.

The first time I pinged my router, I got:
PING 192.168.20.1 (192.168.20.1) 56(84) bytes of data.From 192.168.20.32 icmp_seq=19 Destination Host Unreachable
64 bytes from 192.168.20.1: icmp_seq=1 ttl=64 time=5.33 ms
The last line would repeat, seemingly endlessly (I'm assuming it'll just pining repeatedly until I close Terminal?), changing the number after 'icmp seq=' each time by one. The ping timings would vary considerably with each entry.
When I pinged my router a second time, I got the same as the above, but it did not show this line:
From 192.168.20.32 icmp_seq=19 Destination Host UnreachableIf I tried to ping Google or Cloudflare, I got the same resule without the 'unreachable' line above...
Oh boy, 'journalctl' has some content... I got up to about 3,000 lines before I gave up any hope of copying its entire contents!
What is 'journalctl'? A journal of everything that's ever happened on this computer?
As for dmesg, you can find its output over here:
