My pc does not recognize my router

Hello,
I have just spoke with Lynksys about my problem and they say everything is
fine with my router and I believe they are right. Whats happening is my
desktop pc used to see my router under networking / Vista home premium. But
now I cannot find it and when I search for wireless devices such as my new
laptop / running vista home premium as well it cannot find the laptop. I have
internet access on both the desktop and the laptop. How do I reconfigure my
desktop to share between the 2. When I go to ip config from the start menu I
notice on the black screen there is nothing listed for default gateway and on
my laptop there is a default gateway number...

please advice

Posting the result of ipconfig /all may help. Or check this post:

Hi
Successful Sharing involves some general consideration in Network settings,

As well as specific adjustment of each computer according to what it is
allowed to be shared.
