Was able to connect to my network fine a couple of days ago. Now It doesn't want to work.

Everytime I try it seems like I connected (the little blue globe symbol displays) but when I try and go to a webpage, the connection times out or moves slow. When I run diagnose and repair it tells me that this computer has "limited or no connectivity" even though I'm able to connect to other networks. Selecting the "automatically get new IP settings" and "reset network adapter" options don't work. After selecting these earlier it was telling me "unable to connect to primary DNS server", then it was telling me "windows has confirmed this computer is currently experiencing a network connectivity problem". Now it's telling me there is no problem in spite of the slow connection.

I don't think my wireless adapter is the issue, I'm able to connect to other networks fine. I don't think the router/modem is the issue, there's another computer in the house (that I don't own) as well as my xbox hooked up wireless to it with no problem.

Make sure you have the latest wireless driver from your laptop manufacturer's web site.

Disable encryption on the router and try to connect. If successful you can probably re-enable encryption and reconnect.

Terry, It turns out I didn't have up to date drivers for my wireless adapter. Thanks for pointing that out. I downloaded and installed the most recent one from Intel's website. That seemed to alleviate the problem for a few minutes, but now I'm still getting the same problems.

How exactly would I go about disabling the encryption on my router? I think I'm supposed to just type the IP address into my web browser (Firefox), right?

Intel says (e.g., near the bottom of this page):
Intel is a supplier of laptop components and does not manufacture or sell complete laptop systems. The software provided by Intel below is a generic version. Each laptop computer original equipment manufacturer (OEM) may have altered the features, incorporated customizations, or made other changes to the software or software packaging they provide. The software provided has not been verified by your laptop manufacturer as to compatibility or other operation.
Years ago I learned the hard way that Dell had modified the driver for the Intel 2200bg adapter in my Inspiron 8600.

Type the router's IP address into your browser's address bar, login, navigate to the wireless section and find the encryption (or security) mode setting. The user manual, usually on CD and the manufacturer's web site, has details.

But there is no need to play with the encryption if you can now get a connection.

I hadn't considered that part about the drivers, thanks. I'll keep that in mind in the future.

I think I've resolved the problem with my network. Apparently, all I had to do was go into network and sharing, remove the network and then re-add the network.
