Hi, currently i am running my desktop using window vista business edition (32 bit) which have no problem in internetion connection. However, after a few months, i encountered problem to connect internet with a warning sign stated" limited internet connectivity"

Basically, i am using D-Link USB wireless adapter to connect the D-Link router.

i can assumed that the router is working well or no defects because my housemates are able to connect internet through this router. I can connect to the internet using my laptop which is running window xp as well.

For your information, the limited connection occurs not in regular basis. Sometimes i can connect through the internet but sometimes i cant.

In this case, what sort of information i need to provide u guys so that u can assist me in solving this problem. thanks for your help and sorry for my poor english.
