Wifi connection issues

Earlier today I was able to use wifi on my computer just fine, but now I can’t. I’ve tried using the ethernet cable I’ve connected to a wifi extender, but that doesn’t work. I’ve had limited success by using a wifi adapter - I’m able to connect to the internet but the connection is spotty and sometimes I’m unable to even browse the web.

What can I do to find the source of this issue?

Hi. Sorry you are having this issue with connecting to the net.

Please post the output of:

inxi -F

This will help with a few questions. Apart from that, have you done any recent updates? — Today specifically.

I’m using my phone right now, and don’t know how to copy the output from my computer to my phone when it’s like this. The most I can think to do right now is to take photos of my screen.

I did update my computer twice yesterday, once before the internet problems, and once after, hoping an update would solve things.

If an update broke it, try downgrading the relevant packages to go back to where you were. I’m not sure what you updated, so I can’t tell you what to downgrade without more information.

Just discovered that turning on my VPN seems to allow me to connect, though I’m not sure why.

Check your router DNS settings.

It sounds like your VPN has a killswitch which has been set. Sometimes VPNs will enable this by default. It prevents any network activity from getting through without using the VPN connection. Often the killswitch will remain enabled even if the VPN is off.

I thought the same thing too, but both the “VPN Kill Switch” and “Advanced Kill Switch” options are unticked in the settings of my VPN, which confuses me (though I suppose that’s more an issue with the VPN than EndeavourOS).

Maybe your problem is here:

Device-2: Realtek RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet
driver: r8169

Should it not be the r8168 driver?

I hadn’t actually noticed that myself until just now. How would I go downgrading the driver/getting the correct version installed?

You might want to consider adding:

 -z, --filter  Adds security filters for IP/MAC addresses, serial numbers, 
               location (-w), user home directory name, host name.

I think you can do it in eos-welcome, otherwise check out:


Switched back to r8168, but that only seems to have caused more problems (I couldn’t connect even with the VPN active) but upon toggling back to r8169 I was able to connect again.

Thought things were okay for a bit, but did another update and now my wifi isn’t even showing up in the network manager. I can still connect to the internet using my ethernet cable, at least, but I’d like to know I have the wifi available still.

inxi -F -z gave me this:

Your WiFi is intel chip using iwlwifi module.

Edit: In post 3 you show realtek rtw_8821cu which is a usb wifi adapter? This one is working?

Edit: You could try

sudo rmmod iwlmwm

sudo rmmod iwlwifi

sudo modprobe iwlwifi

The USB wifi adapter doesn’t seem to be working.
Tried the three commands you posted - when I did rmmod iwlmwm I got “Module is not currently loaded” and when I did rmmod iwlwifi I got ‘module is in use by iwlmvm’. When I did sudo modprobe iwlwifi I didn’t get a feedback message.

Have you checked this?

Gave it a try just now and it seems to be working, at least for the time being. If any other problems arise I’ll let you know.
