Last time I called I was fobbed off by tech support, saying that I had to directly connect my PC to my modem. When I mentioned I was using wireless, and that my computer was at the opposite corner of the house, he hinted that my problems may have been caused by someone else using my WiFi!!
I tried to explain that this just was not possible (I'm rather au fait with IT

).
So, he told me to go get a really long CAT5 cable (I'll need about 30metres) and to call them again once I've done that.
Doing that is not really an option. I don't have such a lead, neither did work.
I'm left with:
a) Move PC down to living-room (thankfully, plasma can act as a monitor).
or
b) use one of the many 'spare' PCs I have (bit of a self confessed geek) to build a PC specificially for testing and to keep Tech Support happy.
Gah!
