Wireless Problem

I have an acer aspire one which I got for christmas, and so does my sister.
My mum also has a big laptop.
And we have a wireless network.
But recently mine and my sisters internet stopped working. But my mum's is fine.
It says there is a signal and it's connected. But we can't sign into Msn and internet doesn't work on Chrome or IE....
It works fine using my uncle's wireless network (which i'm now) but not at home...
What could be the reason?

 

Try this with you machine and showing connection turn of or un plug the power going to your Moms modem, wait about 10 seconds and turn/plug it back in. Not sure why but on a few occasions my AAO will sit there trying to acquire the address, if I switch the modem off for a few seconds all works perfect.

No I tried this.
It hasn't just stopped recently, it's been gone for about a month and both things have been turned on off numerous times.
Any more suggestions?

 

I would go over the settings on your Moms check to see if they match yours.
