network connection is randomly disconnected after sleep.
I have a iMac OS X (10.5.8) I purchased in 2009 brand new. For the last 6 months, I have to go thru network diagnostics to verify my network name and re-enter my password for the network. I have an Ipad, Ipod, and laptop PC that have no issues connecting to the network after I have contacted my network to troubleshoot problem, it is not the network. My system software is currently up to date, I did notice that 10.7 Lion had a software update for this problem that I am experiencing. Can anyone give me a solution to troubleshoot this problem?
