Ok, heres the deal: Just built a new comp. Put in a linksys wireless pci card. The problem is it will connect to my my router and the internet for about 4-5 seconds then it loses its internet connection. Then about 4-5 seconds later it will reconnect.
I use the same wireless card on the current computer im using now that is in my basement, wheras the new computer is in the same room as the router. I have switched the cards with the same result on the new comp, and old. I have connected wirely with no problems.
If you are using security, which you should your settings may not be correct. Make sure you have the card setup to connect to AP's only. Def is Any and all. You do not want Adhoc. Make sure you are not mac filtering.
If the pc is going to be that close use a cat5e cable the speed will be much faster.
