linksys befsr41 problem?

i have posted this many times on a couple different forums also and i still cant get any answers, so i thought i would try it here under networking.. my problem is i have a linksys befsr41 router connecting 2 computers 1 windows 98 the other windows xp home both using ie6, dsl, my problem is i can connect to the internet great on both computers but i can not access any emails at all, yahoo,hotmail or excite , i was wondering if anyone knows what i could to do or change.... if its something simple under the linksys options or something

 

Could you be a bit more specific--what error message are you getting--what are your IE settings on both. Also--what are your firewall settings--are you blocking any ports. etc.

 

i dont get any error message, well when i try to log into yahoo, i see that i have new emails but when i hit the inbox button it does nothing it just stays there, then eventually i get that white page where it says this page cant be viewed blah blah, hotmail it wont even go to where i can see if i have email it just automatically goes to that white screen and excite i can log into just like yahoo, and as far as the ie settings i dont know what you mean or firewall settings i dont really know how to check those
