Nostalrius Begins - Quality wow vanilla realm (1.12)

I just began using Auctioneer so as to try out a new way of money-earning. The issue I have, which completely ruins this plan, is that I get disconnected frequently when scanning the AH. Sometimes it disconnects me to the login screen and sometimes just to the character screen. I guess it might be because my character is AFK for too long while scanning? A scan usually takes 1h-1.5h for me. Other Auctioneer users, what do you do to prevent this?

Split up your scans into smaller more manageable scans. Instead if 1 90 minute scan, do 3 30 minute wcans.
