Wired connection problem (Installation of any distro and after)

Leandrogc · 10-18-2021, 09:53 AM

Hi i have a Lenovo G460 with a problem when installing any distro, from the moment i boot with the usb to start with the installation proccess my wired connection stops working, and then when the distro is installed i can't access internet either, i been throught Ubuntu, Linux mint, now im on Manjaro 21.1.5 but i still have the same problem. Before changing to linux i had Windows 10 and the wired connection worked perfect so im guessing it's a linux problem(?

Im relatively new to linux so i don't know what should be the root of the problem

Code:

Device-2: Realtek RTL810xE PCI Express Fast Ethernet vendor: Lenovo driver: r8169

This is my Ethernet Adapter
Here are the outputs for:
ip link list

Code:

: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp6s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether  brd ff:ff:ff:ff:ff:ff

lspci -v

The Realtek RTL810x series is a) quite old, b) a bit rubbish, and c) quite well supported. It ought to work.

Can you boot one of the installation media (or a Live distribution), run the following commands, and post the results:

Code:

ifconfig -a

This should display all interfaces for which a driver is loaded. It's an old (and in some distributions, deprecated) command, so if it doesn't work, try:

Code:

ip link list

And then run this command to display all PCI/PCIe devices and their respective drivers:

Code:

lspci -v

Update: i've searching through similar posts and some talk about a problem with the r8169 driver, along with that doing mhwd on the cli i noticed that i had an available driver configuration which was r8168.I tried blacklisting r8169 driver and installing/modprobing r8168 but unfortunately this doesn't work either.
This is the output of lspci -v when i modprobe r8168:

Code:

It seems that the r8169 kernel module is still being loaded but i don't have any kernel driver.

Update:
After some time of searching trough forums and posts i didn't found any solution, either way in specific cases the connection do works for a couple of seconds which makes me think that there might be a solution.
I leave the output of inxi -Fz here just in case

Here is my old clunker, that works on MX 19.4.

Code:

Network:   Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet 
           vendor: ASUSTeK M4A785TD driver: r8169 v: kernel port: d800 bus-ID: 02:00.0 
           chip-ID: 10ec:8168 class-ID: 0200 
           IF: eth0 state: up speed: 100 Mbps duplex: full mac: <filter>

I insalled (then gave away) MX or antiX on several old laptops/PCs without problem yet with Ethernet.

Thanks for replying!, since the problem stayed in those distros i didn't really think of trying others but now that you tell me about MX i'll try it.
