Was looking for some advice on where to look for a problem that I have regard wireless. New to Arch (this is my first install on physical hardware tried a few times on Virtual box with success), and can use some help. Old laptop that I was running Ubuntu on and wanted to try Arch on it.
This issue has to do with the system hard crashing, cursor just stops blinking and device is completely unresponsive. No keyboard input is accepted at all, and need to do a hard reset on the device to clear. Suffering from a lack of info to help determine cause of crash.
After some trial and error I have seemed to have it isolated to when I connect to wireless with iwctl and wpa_supplicant.
This was occurring on the live image 2021.07.01, after connecting to wifi to run pacstrap I would have between 30 seconds to 2 minutes before the system became unresponsive.
Since the crash was so hard and using live image, no logs to collect. (to my limited understanding)
I have tried the wireless card built into the laptop RTS5229 and a usb wireless device that I had on hand RTL8188EUS. At first I was using iwctl for config but shifted to configuring wpa_supplicant on the live image to connect, going back and forth with various tests. All times it would hard crash in an unknown amount of time. pacstrap would be downloading system and fail.
I have left the device running for a day or two in the live environment to see if it was stable without connecting to wireless, and minus wireless things seem fine.
Cleared out all files copied to ssd via pacstrap, between install attempts.
Started looking further at if it was a driver issue, or some feature on my wireless was incompatible with the available drivers. Modified my wireless config (on AP) to remove various features if I could seeing if something like beam steering would be an issue with no success.
At this point I have almost completed/have completed install a few times with it crashing. If I was to disconnect from wireless the system would be stable, but maybe the system wasn't fully built because I shut off the wireless too soon.
I configured Pacoloco to cache the install files and managed to successfully (?) configure the system; being able to complete the steps fast enough to avoid a crash.
Booting the ssd install, I found that I had the same issue. Both with iwd and wpa_supplicant. System is stable so long as I do not connect to wireless. Can configure most of the wireless settings and leave it and things will be fine until after I "enable" wireless and get IP address from dhcp server. (Have tried with static IP too) Began looking for info on these forums, google, that related to my issue. Ordered wired usb ethernet adapter and system will run fine plugged into wall an connected. Can run updates etc that way.
Tried an additional wireless usb adapter I had, but both my local system and live system are missing drivers. Realtek 8812AU/8812AU. per lsusb. Thinking of trying to get these drivers via git and use them to see if same problem, but honestly seeing that it also Realtek as the chipset is discouraging and want to hear what is said here before proceeding down that path as I have already sunk a fair amount of time into just getting to this point.
By this point the 2021.08.01 live iso was available. Same behaviors on this image. For all 3 wireless adapters that I have. Was lookin on Amazon for yet another wireless adapter to try, looking for a very different chipset. Could use some ideas here.
