I've done a search, but can't really figure it out. I don't have a strong networking background. I have a Linksys WRT54GP2 v. 4 router with a WMP54G wireless card, and a RCA dcm425 cable modem (comcast, not sure which speed). My brother's computer is wired directly with an ethernet cable and gets d/l speeds of around 550 - 600kbps. In the next room over, with an excellent signal at all times, my comp only d/ls at 50-100kbps.
There is no security enabled. Also, my computer is already running SP2.
Even transfers over the network are slow, only getting about 1700k as opposed to the ~7000k when my computer was wired up.I d/led the TCPoptimizer, but that didnt do anything that I'm aware of, and I have no clue what all those numbers mean.
