Norton, Kapersky or other protection has expired. Ping and email might work. There are also other issues such as the date/time on the PC is too far off but I don't see much to work with in your post.
For example, does this laptop work at other hotspots?
I'm having an issue connecting to the internet. I use a wireless USB card to connect to my landlord's router. I've never had an issue with connection and I'm going on day 4 now. I have no trouble connecting to the network, I just cant get on the internet after. I have no problems on other devices: xbox 360, wifi on 2 iPhones, laptop...just my desktop won't work. I run Vista, if that makes any difference.
I went out and purchased a new wireless USB adapter last night and I have the same problem. I've pinged google.com via a cmd prompt and that works. Router has been reset, internet worked for 5 min after router reset, then stopped again. I've reset everything I possibly can think of and nothing.
Thoughts? Ideas? Anything would be appreciated.
