This is not all surprising to me at all, their tech support sucks, and as a company they deserve every little bit of crap that anyone throws at them. I have had horrible problems with their wired routers before all the wireless stuff has come along, and they refused to help me. Same with Belkin and another company. They all outsource now.
I now have my computers networked via multiple network cards off of the main system (essentially using the main internet connected computer as a LAN box). I also have kept 1 router over the years that ironically works perfect, and has never given me any problems, out of all the brands I have ever used. The ironic part is that it is a Microsoft router. Figure out that one.
