[SOLVED] Missing enp0s25 device (cable modem) after installing LAN card

Crotalid · 02-24-2023, 07:12 PM

Recently I ordered a new Motorola MB8611 cable modem, to replace an older, slower NetGear modem (the NG modem is limited to about 650mb/s, while the MB8611 supports up to 2.5gb/s).

In order to get the most of out it, today I installed a 10GTek 2.5GbE card with the RealTek 8125 chipset, since my onboard LAN on my older MSI X470 board is limited to 1GB/s - and my internet plan is set to 1.2GB/s, so I wanted the card to take advantage of its full speed, with the new Motorola modem. I tried installing the RealTek drivers for this card, but couldn't get it to work. So for the time being I tried plugging my modem back into the onboard LAN port.

After I installed those drivers, things seem to have went awry, and now the modem (enp0s25) can't be found, and it won't show up in my network manager on KDE, unlike before. I was successfully running it for a few days here on that onboard LAN port, though. Somehow, it disappeared and I don't know what to do to find it or re-enable it. Running 'sudo lshw -c network' shows that it is missing:

Code:

(base) base@ryzen7-2700x:~$ sudo lshw -c network

Similarly, 'sudo ethtool enp0s25' spews an error:

Code:

(base) base@ryzen7-2700x:~$ sudo ethtool enp0s25
netlink error: no device matches name (offset 24)

netlink error: No such device
netlink error: no device matches name (offset 24)
netlink error: No such device

I'm running Kubuntu 22.10, on an older Ryzen 7 2700x. This is the first time I've run into this problem of not being able to find the cable modem device. It just appears to be gone, and I'm not sure how to find it. Fortunately, I dual-boot with Windows 10, and there's obviously no issues with the physical LAN port itself since I'm using Windows now to make this post, without any connection issues.

Any ideas on why enp0s25 might disappear like that? For that matter, I need to know how to the RTL8125 card working properly, although for now I took it out of my PC thinking it might have been the issue, but it made no difference.

Can you show us the complete output from

Code:

lspci -nnk

That should provide exact chipset details and what driver (if any) is bound to the device.

Yeah, my onboard LAN also uses a RealTek driver:

Code:

(base) base@ryzen7-2700x:~$ lspci -nnk | grep Ethernet
22:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 15)
        Subsystem: Micro-Star International Co., Ltd. [MSI] RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [1462:7b79]

After I uninstalled my RealTek LAN card, though, I deleted the driver files without thinking - and I'm pretty sure I deleted the ones for my onboard LAN as well. My motherboard is the MSI X470 Gaming Plus, which uses the RT 8111H gigabit LAN chipset.

I did reinstall the drivers, using the script provided in the bzip download, from the RealTek page here: https://www.realtek.com/en/component...press-software

I'm pretty sure that is the correct driver and I also tried loading it with modprobe ('sudo modprobe realtek'). It didn't work, even after resetting my system.

You didn't post the complete output as requested. All you appear to have posted here is the entry pertaining to the NIC already enumerated by the lshw command in your first post.

Yeah, sorry, I didn't think anything else in the output was important, and it was pretty long - this is the complete output, though.

I expected to see the "10GTek 2.5GbE card" you say was installed. It should appear in the output, regardless of whether it is supported by any kernel driver or not. Did you remove it?

Yes, I removed it, for now. I was just trying to get my onboard LAN port (the RTL8111H one) working again, after that. As I said, I think I deleted the drivers earlier, but I can't seem to get the newly re-installed drivers for the 8111H to work.

ferrari · 02-25-2023, 02:39 AM

Sigh...it makes what you have posted irrelevant. I wanted chipset details (which obviously depends on the hardware being present).

Ok, so you'd now just like to get the onboard NIC working again?

Yeah, I'm sorry about that - my post was originally about getting the onboard NIC working, or at least I wanted to do that first, until I can find out why the 10GTek 2.5GbE card isn't working. I suppose there was a misunderstanding in the original post, or at least I wasn't being clear enough. Basically, after I couldn't get the 10GTek card to work, I uninstalled it, and switched my modem back to the onboard LAN port, and then I couldn't get *that* to work, either.

But if I can get the card to work, then I suppose it's moot, although I'd have re-install it here, first. I think they both use the same drivers, from what I've found.

ferrari · 02-25-2023, 03:46 AM

I'm not sure whether the r8169 driver supports your card, or if r8168-dkms is needed. Nothing blacklisted?

The r8169 might, but RealTek has a Linux driver specifically for the 8125 card. It's here - https://www.realtek.com/en/component...press-software

I still can't get it to work, even after installing the driver. I already have that 8125 driver installed, as well. I just don't know how to get Linux to recognize it.

I really don't want to have reinstall Kubuntu.

I was referring to your onboard NIC. Let's stay with getting that going for the moment. The r8169 driver is included as part of the kernel. You'd just need to check whether it got blacklisted during the addition of the other driver(s). Check /etc/modproobe.d/ directory for any files containing blackist entries involving r8169.

You could check using something like

Code:

grep "r8169" /etc/modprobe.d/*

Ah, ok. Will here. I'll post the results in a few minutes, I'll have to reboot.

Edit: Running the above command on /etc/modprobe.d/* returned no results. It's not apparently blacklisted.

Ok, please show

Code:

lspci -nnk | grep -iA3 net

If you have inxi installed, you can also do

Code:

inxi -nia

for comprehensive network device and interface status output.
