My Internet connection is driving me batty. According to every broadband speed test I've ever run I have nearly 9Mbps but just lately (last week) I have to refresh a page every time to load it and it takes forever for pages to eventually display - sometimes not even bothering to do so. I've tried with different browsers and that's not done the trick (currently using Firefox 3.5).
Any ideas on what might be going on? Virus checkers haven't found anything and I am beginning to lose my rag as I work from home so my Internet connection is crucial.
