Ok, so I've decided to go the Qoob pro route. But until the purchase/arrival: would a wireless card be causing issues when trying to stream to my cube via my NIC?
I have my cube conected threw a crossover cable but did have my Xbox conected to my router which I had a wirless card in my computer and backup up Xbox games and it somtimes would work and somtimes not. So I moved my router near my computer hooked it up with a Networking cable and never had a problem since. All backups worked. So im sure the Gamecube would have the same problems as the Xbox did transfering wirlessly. Most likly I was getting some packets not sending right or lossing them when i was wirless. So I would recomend you not do it wirlessly
