performance was somewhat crappy on xp (3mb/3mb in speed testing), but even worse in win7...im using vista drivers (no win7 drivers avail)
im on the opposite side of the house, and the cable modem wont come online all the way across the house/up 2 floors. so im using a usb rosewill wlan-nic, which gets about an 11mbit signal from my linksys 54gl router with dd-wrt.

qos config is standard, nothing too special or out of the ordinary.
my question is whether it is a driver issue, or tcp stack issue.
essentially, my web pages are fairly responsive (dns, http - with the added wireless latency)...but simultaneous connections really kill it.
browsing lots of large res photos (open in multiple windows), for example - will completely kill the connection..and it will want to download/focus on one image at a time...then on to the next, versus pulling down data from all at the same time (albiet, at a slower rate).
youtube is painfully slow (or any other flash/video app)...and download speeds have dropped since going to win7 - which i assume is because of the vista drivers/non-true win7 drivers.
on xp, i was seeing about 3mb/3mb, sometimes a little higher on the upstream.
on win7, im seeing about .5-1mb/1.5mb...why am i getting better upstream performance than downstream ???
is there a tcp stack issue, or am i overloading the usb wlan nic with too many concurrent tcp connections? or is that a limitation in wireless as well (getting/responding ACKs, etc...just overall latency loss in wireless?)
