Well, I gave up on my cheap, off-brand router, went down to Best Buy, and bought a Linksys router which was conveniently on sale.
I plugged it in, got it configured, and had everything up and running, including hotmail, in about half an hour. That's opposed to hours of troubleshooting and endless grief with the other router. Take it from me: don't buy cheap, off-brand computer equipment. I got very suspicious with the old router when I talked to their tech support and after several failed attempts at solving my problem, the technician said the router was not compatible with my modem, and I should go buy someone else's router! You know it's bad when the tech support sends you to the competition to buy their products instead!
So now I can watch the Africa cam all day long, and immediately see the emails that people send me about it! Just kidding...sort of. The Africa cam does seem to be causing a rather peculiar contagious addiction to go around among my family, friends, distant acquaintances, and even total strangers and their friends, family, and distant acquaintances. Oh dear.
Oh, look! A herd of water buffalo is there now!
