router problems with win 7

Hi,all I just joined.my question is,I just upgraded my computer to windows 7 home premium 64 bit,and my wife's computer has the router,a Linksys E-1000 and her computer is running,windows 7 home premium 32 bit.Her computer shows the home network is working,but I can't get my computer to link to the wireless router,so I can't download all my stuff from Carbonite.Any idea's ?? this is driving me crazy!!.I had windows 7 home premium 32 bit on my computer and I had no problems.OO, and windows 7 64 bit is a fresh install. Thanks for any help,i don't know that much about computers.

Is the router showing up when you try to connect in the network and sharing center ?

I just gotta ask, If you had no problems with the 32 Bit why did you reinstall ?

no its not showing up at all.I changed from 32 bit,because the hard drive was making some noise,so I did a fresh install of 64 bit.

As Lemur suggested check your wireless adaptor in Device Manager to make sure it`s there and the drivers are installed. I assume this is a laptop ?

No I am sorry,I should of said,its a desktop.Iam writhing from my wife's computer.

So your using the wireless card in your desktop to try to connect to the router then ?
Have you checked Device Manager ?

I just checked my computer,and their are two yellow marks,sorry iam not very good with computer nolage

it takes me awhile to understand some of the stuff

Right click on that and update driver. If it does not work you will have to go to your pcs makers website and look for the drivers. They may not have them for 64 bit. What is the make and model of the pc.
