Ethernet Broken after update

#1

I have just updated my Rock 5b which is running Radxa Debian bookworm and Ethernet stopped working. Is was working fine but now only wifi will work. Is there anything I can do to get it to work again?

#2 
$ lsmod | grep -i "r8168\|r8125"

You should see this:
$ lsmod | grep -i “r8168|r8125”
r8125 163840 0

If you see nothing
$sudo apt install radxa-system-config-r8125-dkms

You should see this:

$ systemctl status wpa_supplicant

How did you update your ROCK 5B? By upgrade cmd ? Or by Radxa system tool rsetup ?

#4

Hi foxsquirrel, i did as you said and after the first command got nothing tried second command and did a reboot and ethernet was working again. after trying the third command and it was the same except for last line that began with 840 and not 762 and i got the following warning message:
Warning: some journal files were not opened due to insufficient permissions.
thanks so much for your quick response i have tried for hours but to no avail!

Nasca, i through force of habit used both rsetup and upgrade command is this not ok?
thanks for your help.

#5

Since ethernet has been working again it does not seem to work as it should in that when i try to download a file in chromium from Radxa it says there is no internet connection but if i turn of ethernet and use wifi it downloads fine. What is strange is that it works although a little slow for ordinary web pages and rsetup updates.

#6

Using the system update in rsetup to update the system is what we recommend.
if you did that, and ethernet does not work either, I can try to reproduce it, then find a solution.

#7

From a console and post results.

  $sudo ifconfig
#8

Thanks for getting back to me. Not much really! I got: sudo: ifconfig: command not found.

#9

Right i installed net-tools and tried again the result was:

Wire is working, make sure the subnet mask on your gateway is the same as your machine.
Turn off wifi.
Are you able to $ping 8.8.8.8 ?

You should see this:

:~$ ping 8.8.8.8

Are you on a work network or home network?

You could also have an issue with your gateway since you are on wire and wifi. Many of the older gateways have issues and do funky stuff. Do you have admin access to your internet gateway?

Hi foxsquirrel, thanks for your help. the subnet mask is the same (its the default for the router) and the ping results are as follows:
ping 8.8.8.8

I am on a home network and wifi is off, My router is only a year or so old and i have admin access to my router if thats what yu mean by Gateway Access.

It worth noting that i have three different distributions that i run on the rock 5b, Armbian, Ubuntu and the official Debian and its only this official Debian that is not able to download large files. It tries but keeps failing, however i am using it for most every day tasks like internet browsing etc and it works fine its just if i want to download a larger file i have to switch to wifi which works as it should? I have also checked to see if it works in another browser but it has the same problem! I tried a new installation with updates only through rsetup and it is just the same.

#12

Not sure what to say at this point.

#13

I had a similar problem with large files using scp (or anything encrypted really). I was a driver issue. Changing to the r8168 fixed all issues. If you used rsetup to update the system, you should only have to purge the old driver. But you can do it manually as I did. It’s very important to purge the r8125 driver off there either before or after putting the r8168 on there.

#14

Thanks for the reply could you tell me what commands I should use to purge the old and install the new drivers? Thanks
