Browser not functioning with Wireless

My web browsers are stopped working when am connected to the wireless internet in my office. the browsers however respond when i use the ethernet or even a internet dungle. How do i fix this?

When you say they stopped working. Do you mean they won't start (error messages?) or that you can't browse pages on the internet?

Assuming it's internet browsing that's the issue does it work ok on other wireless networks? coffee shop, friend house, home etc?

If the answer is yes to any of those then I suspect it's a security policy on your work network and something to take up with your network admin.

If not, post back.
