Btw. The VPN issue turned out to be ExpressVPN’s Arch app. I decided to use OpenVPN instead and now VPN works great.
So that might be something I should contact ExpressVPN about.
Glad I was able to fix that, because now the Eithernet issue became slightly less important. Would still love to get it fixed though.
The thing I would suggest trying is:
-
boot the iso that you installed from and see whether it works there
(note which driver is loaded and compare with your installed system) -
boot pop os - or the iso you used to install it from if you still have it
(and do the same - compare the driver) -
boot any other live OS iso and do the same thing
They vey likely all use the very same driver ( r8169 )
See which one works and which one doesn’t.
I only use wireless - and I’m not sure wheter NetworkManager will automatically use a wired connection or whether you actually need to tell it to use it.
You can give one or the other priority in Network Manager- General Tab for the individual connection , On my (xfce) system, it is checked with -999. I don’t know if that -999 was by default or I put it there for some reason or another.
@Nachlese Thank you. Btw, I’m sorry about yesterday. I was just really fad up with this whole situation and I kinda took it out on you when I didn’t even provide the correct info. I apologize.
Anyway. How do I force networkmanager to use a specific connection?
Can I perhaps force the connection based on its UUID? Because it does list the UUID for a wired connection.
So here’s what nmclt shows me:
ExpressVPN - Washington DC 6a76a4ad-a93e-44a4-81c9-1cd817c30cf7 vpn wlp0s20>
tun0 06254d5f-c80c-4f4f-9453-8481c4f78223 tun tun0 >
Wired connection 1 9a552d13-c442-38aa-b28f-ec1955d14090 ethernet –
Btw, I tried the r8169 driver. Didn’t work.
Wired internet did not work from the Manjaro live USB btw.
You said I should note which driver is loaded and compare with my installed system.
How would I go about doing that?
I was just thinking
since I do have a few different iso’s of other OS’s around …
and if you had, too
you could just relatively easily try one after the other
… as if you’d want to install pop OS again, or Mint, or whatever …
boot each one up and see whether Ethernet works.
It should.
You said it was working on pop OS.
It’s important to know whether it is actually working
and only then try to find out why it might not in specific circumstances.
Always do the easiest thing first.
… easy to do in that case (live system) - just don’t set up a wireless connection at all …
I don’t know how to force it - I guess by just disabling the wireless - or by having it not set up and configured at all - or by selecting this connection …
I don’t know and can’t test either because I do not have the option of connecting to a router by cable.
Not right now and not for the next two weeks, at least.
It’s just to see whether the Ethernet card indeed works.
No vpn.
It just adds complexity.
Just see whether the thing works in one OS but not in the other.
As for how to check for the driver used:
inxi is only installed by default in Manjaro.
No other distribution will have that on their live iso.
(but all have the option to install it. Just try.)
So you could check which modules are loaded by looking for that specific one with either:
lsmod | grep phy
or
lsmod | grep r816
Will work on any distribution.
It would just be good to know whether the thing works at all
before trying to troubleshoot a already broken device.
Much more likely is a faulty cable or it’s connection!
Triple check that possibility.
One more easy option is:
install another kernel or two - older ones.
5.4 and/or 5.10
and try booting your system with these.
Always do the easiest thing first.
Thank you @Nachlese.
I believe I’ve finally been able to figure out what the problem is.
I’ve tried without the wireless connection and I’ve tried older kernels too with no luck.
Then I tried an old laptop I had laying around. The ethernet cable that I was currently using did not work on that one either. Then I tried a different cable, and it worked.
However, it still does not work on my Manjaro installation.
But I guess you were right about it being a faulty cable. Or perhaps it’s the router.
I’m gonna have to look further into that.
I believe this case is closed, even though I still cannot use wired internet on Manjaro. But it has to be the cable or the router or something like that.
Thank you so much for you guys’ help.
