Killer wifi card messed up from respin #106

Closed roushrsh closed 5 years ago

roushrsh commented 5 years ago

Hi,

I had initially got some cuda/nvidia problems when at 19.04 which basically killed grub/ any display driver.

So I clean installed as 18.04.2, ran the respin curl, and everything was working great. A day later I noticed my wifi was dropping. I would have to restart to fix the issue. I changed network-manager, changed the killer drivers, so on and so forth, for days. I then found a lot of threads of people with similar issues, and they ultimately ended up having to change their killer card for an Intel 9260 to solve this problem. I thought maybe it's a kernel issue and went up to 19.04, and although the frequency of disconnections decreased, it still occurred at least every 10 minutes.

I re-installed again, everything seemed to be working, I ran the respin and installed everything again, and right after wifi was dropping again requiring me to restart network manager.

This time, I clean installed, exact same as before, but did not run the respin. No issues, killer card is working no problem. I've manually installed all my drivers (nvidia and whatnot).

I'm not sure if the respin is installing an update for the card or not, but it's breaking the wifi for many people on 18.04 and 19.04.

Uhm, this is very strange! I'm currently running 19.04 (with CUDA) + my own respin script. The xps-tweaks.sh simply downloads latest firmware for our WiFi card. If you have time, you could simply comment out the rows downloading the firmware (comment rows 163-165)

Strange. The display error only occurs after upgrading to 430 and according to someone who contacted dell it's a known issue and their only solution is a clean install. I'm not sure what the precursor is to cause it.

Edit: I commented out the lines 160-165 to not update the WiFi card and after running the script without the wifi driver update portion the problem returns. I'm going to clean install again. It seems to be something else the script is doing.

Edit 2: After installing everything manually from the respin (+cuda) results in the same issues. I reluctantly ordered a 9260. I'm still not sure what point is exactly causing it. This time it occurred after I installed cuda. Another was after I changed the grub loader by adding nomodeset. Both times I had installed the other before doing it so it could be one of those, or any of the other things I updated prior (such as running upgrade after every install).

Good luck to others who run into this issue. I'll update if the new wifi card doesn't fix this issue.

I'm sorry I can't understand what is causing the issue... The weird thing is that a lot of other users upgraded to 19.04 without problems (apart from the random freeze experienced with the nVidia driver). I myself use also CUDA (for 18.10) for the University

I just wanted to say changing wifi cards to 9260 works. No surprise there I guess.

I've upgraded 18.04 to 19.04 and downloaded additional ath10k driver WLAN.RM.4.4.1-00140-QCARMSWPZ-1. The connection stopped dropping constantly. So far so good (knock on the wood). Only downloading wifi 6 driver on 18.04 did no good.

EDIT*: Problem not fixed entirely, but connection is much more stable. Now I can at least run apt upgrade without d/c.

I’ve always had issues with the killer wireless card, I upgraded to intel’s latest AX200 WiFi card instead of the 9260. It works well after installing the latest 5.2 kernel and corresponding drivers from intel. The script never caused me issues with the killer card, it was always the killer card that caused the issues on both windows and Ubuntu for me.

Intel is known for making very good network cards, but am I the only one who never had a problem with Killer cards?

aidanthewiz commented 5 years ago

My GUESS is that killer does in fact make good cards, but they have a bad manufacturing process or bad quality control, and definitely not the best drivers. Intel seems to have it down to a science, never had an issue with an intel card dropping or having bad performance. Killer is just smaller and probably doesn’t have the same resources available to make almost every chip perfect or make quality drivers.

An update: I've replaced Killer with Intel AX200. It works great. However, I had to upgrade kernel to 5.1+ and download newest drivers for Intel from linux firmware git tree.
