Hi guys, sorry to have been absent from my own post for so long, I have been working at this in between other things.
A brief resume but by no means everything I have tried.
New minimal install of XP Pro.
Checked date and time.
Followed to the letter all instructions here http://support.microsoft.com/?kbid=813444#4
Tried Opera browser.
Tried altering MTU settings on the network (this was a last ditch attempt, I am on dialup but as someone said, I had nothing to lose)
I am beginning to think this must be a network adapter problem, somewhere in the settings. The 865 is the only one on my wireless network that doesn't have a USR card.
Any experience of thoughts to share guys? Been at this a while now!!
