Wifi not detected

[Guest]

I have a home wireless network with 4 laptops and 1 desktop. A new Toshiba
laptop running Vista Home was added about 1 month ago and all was fine. THen
last week we had to replace our wireless router and since then I cannot
connect the Toshiba at all. All the other computers running XP Pro are fine.
I reinstalled the driver for the wireless adapter - no help. I have run the
diagnostic that comes up when you can't find a network to connect to and I
get a message saying that Vista can't find any problems - contact my ISP. 45
minutes with my ISP Tech desk and they have no idea what's going on.

I upgraded to VISTA Ultimate during this process thinking that might be more
robust like the old xp home vs pro issues. no luck.

It will connect to the internet if I pull the connection out of the desktop
and put it in the laptop so it's definitely a wifi issue.
THanks

thte router change and continues to connect just fiine.

Have you tried turning off WEP or WPA?

Alternatively, try typing the key in hexadecimal rather than ascii characters.

I can't get to the point of typing in the key. I'm not sure that I can get
to the point of turning off WEP or WPA. Aren't they part of that same
process. I'm not even getting a possible network to try and join/login to.
We live in an extremely wired neighborhood and I used to have 6 or 7 networks
show up as available. No I see nothing.
