Solved: HP-EliteBook Wifi Adapter ax-200 Issue

Oktay · ‎01-15-2021

Hi

I replaced my laptop original wifi adapter with Intel AX200NGW but I cannot connect any wifi. I cannot even list them on Ubuntu. For a moment I think it tries to connect to my saved wifi (Hotspot xiaomi poco x3) But Ubuntu immediately says it is deactivated. After that point the wifi list seems empty for a couple of minutes.

I read the following post and run the needed commands I am sharing them now

https://community.intel.com/t5/Wireless/wifi-6-ax-200-issues-on-Ubuntu-20-04/td-p/1215902

-AX200 is not my original adapter and I installed/replaced it with the old one:Wifi adapter Realtek RTL8822BE

-Laptop model:HP-EliteBook-755-G5

-5.4.0.62-generic

-Issue always exist, just when trying to wifi I cannot connect or list them

Some commands output for your information:

@n_scott_pearson thanks for reply

I have solved my problem with the wifi adapter. But It has nothing with to do antennas.

Here is the solution path:

In dmesg output I think main problems were

[ 599.424516] iwlwifi 0000:02:00.0: Microcode SW error detected. Restarting 0x0.

[ 561.910974] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-cc-a0-50.ucode failed with error -2
[ 561.911003] iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-cc-a0-49.ucode failed with error -2

It seemed if I try to connect to my mobile phone's HotSpot. Microcode error comes. So I installed a modem and tried to connect it and there was no Microcode error. I was able to connect but somehow it was unstable especially when I disconnected modem. The OS does not list the modem in the wifi list for a couple of minutes. I tried to restart to make it list but again it was very unstable and does not list the modem for a long time. I tried iwlwifi-cc-a0-50.ucode with no luck.

So I have tried to upgrade the kernel 5.10,5.9,5.8 with the appropriate firmware in the dmesg output and lastly 5.7 was more stable(according to dmesg output). But listing was again unstable and to see the available WiFi points, you must be lucky So I have thought it may be related to power saving, and investigated to disable it completely.

after many tries and creating the /etc/modprobe.d/iwlwifi.conf with the contents, listing is now working properly I can always see WiFi list as it before, connect/disconnect them without any issue. and dmesg output has not a continuous log now.(enable_ini makes dmesg output continuous with some log.)

options iwlwifi power_save=0
options iwlwifi uapsd_disable=1
options iwlmvm power_scheme=1
options iwlwifi enable_ini=N

Working Environment

Kernel 5.7.19

iwlwifi-cc-a0-53.ucode

"dmesg | grep iwlwifi" output is below it is constant now, does not change.

The way you are describing it, it sounds like the antennas are not properly connected to the card.
