RE: Router help
Netgear and Linksys are both fine, actually. No problems with either. Dynamode make some good kit. In fact most of it's pretty much a muchness these days.
One thing you could try is replacing the micro-filters (perhaps borrow one from a friend to test?) because they cause a lot of problems like this when they fail. I'm talking about the small box that "splits" the broadband and telephone signals, usually plugged into a telephone socket.
These small "consumer" broadband routers seem to have a service life of only a year or two, for some reason.
Please don't take what I say too literally. I'm a clown, when it's all said and done. Sometimes I say things with my tongue in my cheek to make people laugh, but please rest assured I am not laughing at *you*!
