Wireless connectivity

Hello, I am new to this forum.

Also, kind of new to computers. I have a wireless internet connection problem and I'm sorry if I can't explain everything properly but I will do my best.
My housemate has a wireless router which connects to her laptop no problem. The internet on the PC in the house is working fine.
So I bought a laptop and I am having a problem getting on to the network.

Both her computers are McIntosh and she is running windows live. I have Windows 7 home premium. If that makes any difference........?
Also, I have the option to connect to her network and the password but it's not working.

I've tried following the support assistant on the PC. I've reset the router and still nothing.
My laptop says Problems found: Problem with wireless adapter or access point.

How do I check what the problem is?

I know I am just a girl but I need help too.

Fine; I promise - - GENDER is not the issue :wave:

Macs and PCs can co-exist nicely so don't fret on that issue either.

Let's gather some info for a baseline:
  • please report manufacture and model number of the common router
  • also report the Windows Version/Edition/SP level
    eg: Windows XP / PRO / SP3
    Windows 7 / Pro / sp?
  • and try to document your WiFi adapter see below

[*] right-click My Computer -> (meaning goto ) Manage
click Device Manager
find [+] Network Adapters in the right pane and click on the [+]
one entry will contain blah Wireless blah
copy that line precisely and then

follow-up with a-thru-c
