Thanks for the recommendation. I installed a Linksys LNE100TX today. Speeds are a bit better, and the "hanging" seems much improved, but it still does it occasionally, still at that same point (20% on 3 MB file, 10% on 6 MB file, etc.)
Also, oddly, the other computer on my net (using a wireless connection, whereas mine is wired) still has higher speeds than mine! (older computer, older CPU, less RAM, etc.)
Clearly, there is still some problem with my computer itself, or so it would seem. Could it be the cable from wireless router to PC?
Any other thoughts?
Still only getting about 3400 kbps, whereas I'm paying for 6000. (Other computer regularly hitting 4100)
Thanks, again, for any help.
