3Com’s SuperStack II Hub (3C16593A)

We just bought from an auction 2 of these hubs. Hooked them up and now it seems that these hubs will only randomly allow users access to our LAN. (I can’t find any unbiased reviews on these in the internet.) A perfect example and true story; Our accountant could not login in yesterday so he went home, but can login fine today. The changes I made, NONE! Swear to God! Is anybody else sharing in my frustration with these hubs? This is happening with several users, including me. I could login yesterday and can’t today. No software added/deleted or any other changes were made!
