Wireless Woes - Cannot Browse

[PureLoneWolf]

Hi all

I am having some issues and cannot for the life of me figure this out.

I have come over to the UK to visit family and my work laptop cannot browse for more than a couple of minutes at a time. Chat clients all work without issue, Dropbox doesn't have a problem. The Cisco VPN client connects happily when it needs to. Just the browsers stop being able to resolve IP addresses.

I am connected to wireless correctly, I get an IP (192.168.0.6) from the router (192.168.0.1). DHCP provides the DNS without issue. I can ping the router and the ISP DNS servers...but still no joy.

I managed to get some joy when running ipconfig /flushdns everytime it stopped. But this is inconsistent.

Firefox, IE and Chrome all work for a couple of minutes after a reboot and then just stop being able to browse. As I said, when it stops, I can still ping everything listed above comfortably..but no host names resolve.

My Android phone connects seemlessly and doesn't drop out. I am typing from my parents laptop at the moment..no issues, my brothers laptop, no problems.

Every device seems to work without issue except my work laptop, which I use wirelessly at home, in hotels, starbucks...you name it, I can use it no problem.

I have removed the connection and re-added. I have connected via standard WPA2 key and last night tried via WPS. Each time, the laptop connects without issue, all of my messengers connect...2 minutes into browsing the web...DNS stops resolving. I even added Google DNS servers and set a manual IP...same issue each time.

Any ideas would be greatfully recieved. It is a Windows 7 32bit Enterprise Dell E6400, locked down but I have admin access to anything not controlled by group policy.

Cheers

*****EDIT*****
And in true post a question after spending days looking for an answer style...

I found the Winsock Fix for Windows 7, applied it and restarted. So far so good...obviously, I will come back if it fails again

Cheers

Any ideas?

**EDIT**

Trying a new profile now...so far so good..time will tell lol

**EDIT**

OK, the new profile seems to be fine, but would be good to have ideas on how to fix the existing one...it is my work domain profile...so I can't replace it for a week :S
