[iloveu2_21]

i brought my laptop to europe with me, and when i got back, i havent been able to access the internet. I am connected to my houses' wifi, and it says connected, but i cant get onto the internet. i tried to deal with the firewall settings and system restores, but it gives that page, "please refresh/not connected", even though i am. and mcafee says i need to fix im/email settings, and i click fix, but it never officallt says fixed. does that have to do anything with this? any suggestions?? thanks!

Go to a friends computer / take a memory stick / go to the microsoft site, and download the latest Internet Explorer, to the stick, and install on your computer.
