LOL. Been there. Network stuff can be a real mind bender. So many places things can go wrong, but also traceable by eliminating different phases of the chain. Try everything else I suggested. Start with keeping Console open to try and see if the system is complaining about anything at the time the connection drops. Then next step I would suggest is go straight to the modem via Ethernet if you're using your own router.
