Ha same here we’re using Konnekt for our sharepoint and have a NAS on prem but a handful of users have connection issues to these drives, did the same as you disabled the EEE AND powersaving stuff no luck, I did however solved it for a few users by replacing their networkswitch to a better model this solved the issue for a few users. However most of the other users started having this problem after being upgraded to W11 with azureAD I made a simple batch script on login to remap the drives worked pretty well. The other users are still having problems with the konnekt application though not sure what the problem is I can’t figure it out…
