Leave it run a bit without the client and see if you get any time outs. Then let it run with the client and see what happens.
Do you have another PC you could try on your network to see if it's specific to that one?
Hmm, Is the network connection from your PC only wireless? If so, have you added any new wireless equipment? I know some wireless phones can interfere with wireless networking if they are on the same frequency or close to it.

Not sure what else to ask. Hope ya get it worked out. I can't wait to turn in some old fishing loot. I been hoarding that stuff for years lol.
