I have a dual boot system (Ubuntu 22.04 + Windows 8.1 pro) running on Dell Precision M3800. Suddenly, network has stopped working, both wifi and wired, on both Windows & Linux.
Following are two events that might happened over the last 2-3 days:
Windows update (the forced update it does occasionally on reboot) was interrupted in between. I knew it could be risky - but it seemed stuck hence I terminated. However, I am 99% sure network was working even after this.
I might have left my system on, with power adapter turned off, overnight. So it might have hibernated OR forced shutdown due to battery discharge. However, I am not sure of this.
In any case, the biggest problem / surprise is - I reinstalled Ubuntu 22.04 just now - and still - the network adapters were not found. I am pretty surprised what could have happened at the system level that suddenly network adapter is not detected.
Any help would be highly appreciated - either to enable the adapter in windows or linux.
Thanks much Regards, Janak
