Certain webpages cause me to lose my internet connection, but I stay connected to my router.

I hope you have your thinking cap on.

I'm having the strangest problem.

When I boot up my computer I can connect to the internet (throught a
WNP111 wireless adapter). I can do a myriad of things online. I can
check my gmail. I can watch youtube. I can browse digg. I can even
do pretty intensive things like video chatting on Skype. None of
these things cause a problem. However the second I try to check my
webmail, or if I try to download certain podcasts (like Scientific
American) I lose my connection to the internet. It's strange because
I stay connected to the router (with a pretty strong connection) but I
am no longer connected to the internet through said router.

Things I've found while trying to fix this:
-At least two other computers on this network can access the webpages
that cause me so much trouble.
-I've used my wireless adapter on my roommate's laptop and his laptop
has no problems.
-This same problem happened at my last house with an entirely
different router.
-If I unplug then reattach my adapter it seems to reset the connection
and I can access those functions that do not cause me trouble.
-I've uninstalled my adapter and reinstalled it with the latest
drivers, it had no effect.

If anyone has any suggestions I could really use them. This is
driving me nuts.

-Thanks

 

I will give it a shot, however, I have tried the adapter on other
computers with no trouble.

 

Hi
It could be that the adapter is defective.
However short of getting a new adapter you can try this.
