[KenshinX]

i just set up U.S. Robotics router and usb adapter 5470 and i hooked it up correctly cause i can go to websites and surf the net but when i go to sites like ebay and yahoo and login in it gets stuck and says page cannot be found or is extremely slow loading it does not do this when i disconnect the ethernet cable from the router and put it directly to the 1 computer so that it is connected to the modem.................any advice help me cause i goto these sites frequently

i also thought it was my encryption which was 56bit so i up graded this hoping this would solve the problem but it didnt

Are you experiencing any packet loss? This is what it should look like when you ping a site such as google.com:

bash-2.05b$ ping [url]www.google.com[/url]
PING [url]www.l.google.com[/url] (64.233.167.104) 56(84) bytes of data.

rtt min/avg/max/mdev = 51.235/56.413/61.748/3.880 ms
bash-2.05b$

Notice the 0% packet loss, i'm running Linux so in windows this probably looks a little different but thats the main idea.
I would suggest you get a packet sniffer such as ethereal, and see what's going on with those packets. To me it sounds like your routers firewall is your culprit.
