DHCP connectivity in Windows XP

Hi network experts,
I have a confusing problem with my Sisters wireless.

At my house, her laptop connects to my wireless and contacts the DHCP server no problems. My laptop does the same. At her house, my laptop connects to her wireless and contacts the DHCP server no problems but hers cannot contact the DHCP server.

I have made sure the WEP key is correct, the Key Index is set and tried ipconfig /renew, resetting the modem to no avail...

She can also connect to her university wireless no problem. (And no before you ask, the connectivity problems occurred before she connected to the university wireless).

The wireless modem router is a DLink DI 524

Cheers

Hi gsalier,

can you ping the address of the router in the problem scenario if you set a static ip within the approp range?

Cheers!

No... tried that

how about if you manually wire to it?

ASKER

Yes that works

i would say that you NIC doesnt support working with that type of access point, can you remove all security and then try again

ASKER

The security is identical to my wireless and connects fine to that.

ASKER

It used to connect just fine until I reinstalled windows xp

If its SP2 then there are a few bugs...
