Wireless says connected, but cannot access internet sites

[cmathies]

Hi,

A few months ago, I was having a problem where when I tried to access the wireless internet on my laptop, it said it was connected, but wouldn't let me access any sites. I fixed this problem by updating my internet security, and it let me access sites again.

I am now having this problem again, however, updating my internet security does nothing to resolve the problem.

The internet is working on my desktop comupter, which is connected via a cable. It is just the wireless internet on my laptop that is not working.

The issue I think may be this:

I usually use my laptop at home, connected to the wireless here. Yesterday, I took my laptop to university and connected it to the wireless there. When I brought it home and connected back to my home's wireless, that was when I could no longer access internet sites.

As I said, it is saying that it is connected, and that I have good signal strength, so there is no reason I shouldn't be able to access sites. When I try and diagnose the problem it says there is nothing wrong.

Please help!

Thanks,

Caitlin

Try a System Restore to when it was working.

Can you get internet access on the laptop with an ethernet connection?

For an attempted connection please show ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.

If necessary use a text file and removable media to copy the results to a computer with internet access.
