Ethernet Realtek PHY RTL8201EL problems

#1

This network adapter. Realtek PHY RTL8201EL is having many miss behaviours and causing problems.

  1. never conects to the internet. now matter how i configure it. manual ip. automatic, etc.
  2. sometimes it does not even show in the tray as it was not even detected.
  3. trying to shut down the pc, or restart, with the ethernet cable connected to the port will cause manjaro to not shut down or restart. it will just hang on a screen. sometimes with things writen on it. sometimes a empty black screen.

also i have some other stuff about this i would like to say.

  1. it used to work on windows 10 and 7
  2. i already unistaled linux and went back to windows 10 and the ethernet works fine. i did this many times going back and fourth from linux to windows, and it only fails in linux.

here is what the terminal says about my hardware.

also while i was filing this bug report i found this console has problems that may be related to what is happening with my network. you see. it thinks my mother board is ASRock 939NF6G-VSTA. its not.
my mother board is a n68-s3 fx
this is a link to the official manufacturer of my mother board https://www.asrock.com/mb/NVIDIA/N68-S3%20FX/
and this is for the motherborad manjaro thinks i have https://www.asrock.com/mb/NVIDIA/939NF6G-VSTA/
if you check the specification of each motherborad you will see that they are completely diferent.
chipset is diferent. cpu suported is diferent. the network card is not same.
could it be that manjaro is detecting the wrong hardware, and this is the cause of the malfunction of my network card? and if this is true. my whole hardware may be in trouble.

Fresh Manjaro install, ethernet not working.

Firstly I would check for a bios update. Second thing is if you are dual booting with Windows then Windows can disable your network card. To check if this is the issue, power down the computer. Unplug all power cords, and remove all backup battery power sources. Give your computer at least a couple of minute to drain all residual power. Then boot directly into Manjaro.

Try disabling then enabling your adapter in bios. Sometimes reseting your bios to factory default helps as well.

See if that helps, if not:

Please post the outputs of:

rfkill list all

lsmod

lspci | grep Realtek
#3

my bios was already up to date. 1.20 the last update the manufacturer realesed, should i try it again?
i was not running dual boot. i removed windows last time i changed to linux, because i had given up and decided to go on wifi alone, but changed my mind once the wifi problems started anoying me. and so i came here to seek for a solution.
i already did power down the compputer and removed the battery and disconected from the psu.

after doing this i can no longer boot into manjaro, a black screen is all i got, and is stuck there.

#4

This is a far more serious issue than your Ethernet not working. I would suggest creating a new help thread with full background info on what caused this.

Information on how to post hardware specs and logs on the forum:

#5

by the way when i said a black is all i got, i meant that after the bios screen when the login screen for manjaro is suposed to appears it hangs forever in a black screen. i get the bios screen normaly no problem.

what caused this, i installed linux. ethernet did not work. i came here for help. followed your instructions and there that is how it happened. nothing more to say

editing to ask if my clarification on the black screen thing changes anything before i go created a new help thread

#6

It has been 4 hours since my suggestion to start a proper help request on your current problem, and I see you have not done so. Not only do you not follow my suggestion to get proper help, you make a post inferring my diagnostic commands somehow were responsible for your computer being unbootable. The diagnostic commands I gave you only return information, they change absolutely nothing on your system.

Create a proper help request giving full information about your system if you expect to get your issue resolved. I would also suggest you be more responsive and polite to those who offer assistance (if you expect help).

Good luck with getting your issue resolved.

#7

am i missing something ? to me it looks like inxi says you have a N68-S3 FX and you say its a N68-S3 FX .
where did that other model come into play?

#8

Try reseating the battery and all the connections that were unplugged.

Does ctrl+alt+f3 get you to a TTY from the black screen?

#9

it later on the network part talks about the other motherboard. just read the whole thing and you will see

here is it

Network:
  Device-1: NVIDIA MCP61 Ethernet vendor: ASRock 939NF6G-VSTA Board 
  type: network bridge driver: forcedeth v: kernel port: d080 
  bus ID: 00:07.0

i did not posted a new help thread because i could not acces my computer due to the problem i was talking about. my last post was from another computer from someone else that i could not have access 100% of the time.
also what i did that caused the black screen was the removing the baterry. that is all i did.
i did not get to do the other commands because i was doing things in order it was sugested

but my missfortune may be of use to solve this problem as i did not had the manjaro liveusb i had to use something else. i used a debian, linux mint. fedora 28 and 29, my ethernet will not work on any of them. i think this proves its not a problem with manjaro, maybe its the nvidia driver.

i tried to look for nvidia site a way to report this issue but i only found areas accepting bug report from graphic cards no place to put a thread about networking.
i think they dont support this network driver anymore

i dont think you can help anymore
unless you want to take nvidia job on supporting this
if that is so i will download the installation for manjaro again and we may continue
edit to fix a missing word

#10

there are 2 models of your motherboard, N68-S3 UCC and N68-S3 . one has the ability to Unlock Cpu Core.
N68-S3 has updates to 1.20 like you already have.
N68-S3 UCC has updates up to 1.60.

im not saying this is your answer but you might want to get your eyes on the board itself and double check, just a suggestion.

#11

there are more than 2 models of this motherboard. mine is not N68-S3 nor N68-S3 UCC, mine is N68-S3 FX

this is the ucc https://www.asrock.com/mb/NVIDIA/N68-S3%20UCC/index.asp
this is mine https://www.asrock.com/mb/NVIDIA/N68-S3%20FX/index.pt.asp
and this is the last one https://www.asrock.com/mb/NVIDIA/N68-S3/index.asp

i just figured out. the reason of the black screen after trying to reset the motherboard may just because by default it boots with USB first. i may had a non bootable usb when the problem happened. black screen is what my pc gives me when i boot with usb boot and not bootable usb

#12

everything is working now?

#13

ethernet still not working.
other than that its ok.

by the way since i need internet i had to make this be a dual boot.
while previously i was not dual booting with windows now i am since this is the only os that the internet works. what was the worries about it?

#14

im looking for drivers for the rtl8201, realtek has not even 1 mention of that card anywhere on its site.
im looking elsewhere, your other option would be just buy a cheap network card or usb dongle for like $5-$15 and use that, at the very least it would be an upgrade to the integrated one on your board.

can you post output for
lspci -nn
mhwd -li
dmesg | tail -n 60

#15

better yet

dmesg | grep -i -E 'eth'
#16

it looks like rtl8201el is just another name for nvidia mcp61 ethernet which both use forcedeth driver.

same problem and a solution:

Please post the outputs @dglt requested if your issue is not resolved.

edit: my ethernet cable was disconected when i did this so i could shut down and reboot. i think i mentioned before that if i try to shut down of reboot manjaro with the cable connected it will hang on forever and never reboot or shut down. now when i connect the cable it will not detect as if i did not even had a ethernet card

#19 
ping 8.8.8.8

after your booted up and connected and see if it returns anything

#20

@tbg would know more about this but i think your ethernet adapter needs to be set “up”

sudo ip link set enp0s7 up
sudo systemctl restart NetworkManager
