IT Support !!!!

Finally sorted out my wireless router today despite all the so-called "help" from both the ISP and manufacturer's support team. The latter group actually surmised that it was "broken" and had a "hardware failure" - which was, of course, out of warranty - blah, blah, blah..

Well blow me sideways but a "factory reset" and the original settings seemed to get it going again with a few tweaks. The question is do you actually have to have a knowledge of IT to work in it?
