Can't load forum page

I have a annoying problem.
At work on their wireless network. I can’t load our forum page. It hangs between 77 and 86% And goes no further.
I have a Thinkpad running 10.3 32 bit.
I have tried both Firefox and Konqueror and both browsers stall at that % .
Their networked computer connects no problem.

Both the old forums loaded with no problems.
I also have problems with Gmail hanging at that percent also.
Hoping someone will have an answer or advice to help sort this problem out.
