Hi, fairly noob here and need some help. A BIOS update over six months ago broke something, and I cannot get any networking functioning (device ethxx not found).

I now finally found the time to try and fix, but after looking through many similar threads, I've not found anything that works for my case. have tried deleting network.cfg et.c. The only thing that works so far is making a fresh install (using 6.12.8 that I was on back then) - I can access the LAN and internet without any issues immediately, both from the GUI and I can also log in via the webGUI.

 

I have the flash backup and I assume I can copy over config files for array et.c. to a fresh install? (ie all the stuff that took time to configure)?

Question - which files should I copy over? 

 

Thank you very much for any assistance - I have limited time to start with and have wasted plenty of my free time already without getting anywhere 😭

Typically you restore the complete /config folder, but if the issues returns after that, it suggests the config is the problem.

Thanks, apologies should have specified that - yes I did try to just copy over the entire Config folder, but the problem persists... (I did also pull the diagnostics, attached here as well if that helps in any way).

 

I came across this post, where you suggested for OP to try and copy over settings, possibly a few at at time to try to isolate the issue: https://forums.unraid.net/topic/123672-upgraded-from-692-to-610-device-eth0-does-not-exist/?do=findComment&comment=1128067

 

That ties into my questions, I guess - which files/folders from the Config folder should I try to copy over? 

I have also tried deleting the network.cfg file and replacing it with the same from the fresh 6.12.8 USB but that didn't help (the file actually was identical to what was in the base 6.12.8 install package...).

You can just restore the bare minimum, like the key, super.dat and the pools folder for the assignments, also copy the docker user templates folder, if all works you can then reconfigure the server or try restoring a few config files at a time from the backup to see if you can find the culprit.    

Awesome, thanks for the details - will do that and see how it goes 🙂
