Any suggestions on how to better upload speed. The ISP I currentlIuse has an 18/2 download to upload speed. I am using a linksys wrt 300N wireless router. I have already tried updating firmware. There are no available updates for this unit. I have also tried having any devcie on my network disconnected from the net so it is solely my console plugged in. It is the slim line so it is wireless. Ethernet doesn't change it.
