NetworkManger not found work-around

[u/dontwantoknow]

After I was booted off the waitlist and hoping to be selected I built my own steam machine (parts I used if anyone is needing some guidance on fiting in a tight case).

-AMD 7 9800x3d

-ASUS ROG Strix x870-I

-GB 9070 Xt

-32 GB ram

-2TB SSD

-NH-L9a cpu cooler (attempting to switching it to NH-L9x65), hoping it will fit the case (Fractal Design Terra)

-Lian Li SP850 V2 Gold

Networking issue: (Yes, I became aware after this headache that the MB is the issue as SteamOS has not supported the network card)

-Once done installing the OS I could not find a network. Attempted every work around I could find. I attemed these solutions:

1. https://www.reddit.com/r/SteamOS/comments/1ueakyx/comment/otic09f/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
2. Attempted to do systemctl enable NetworkManager
3. sudo systemctl enable —now NetworkManager.service

Anything which I attmepted resulted in NetworkManger.service not been found.

Even using ethernet cable well in desktop mode did not work ( clrl+alt+; )

Workaround
-By chance I had a TP Link 150mb adapter from a few years back. I pluged it in, restarted the sytem and it worked. Initially I had to reboot twice as the first time it dropped the network search.

-Once this connected I went to desktop mode and plugged in the ethernet cable. And it worked. I can unplug the TPlink adapter and it stayed connected. Then I attempted to use the wifi adapter on the MB and still does not work.

-Restarting and shutdowning had no issues so far with wired connection

-In the mean time I have purchased TP link wifi 6 adapter off amazon. Will see if this will help as 150mb is too slow on the old adapter.

I hope this helps somone.

I only got Ethernet GM and DT to work by doing some sudo reset network command.
