What you're trying to find out is if it's a problem with your ISP, Modem, Router, Wireless card or something else. Then you can try replacing the issue.
Keep in mind that WiFi runs on the same frequency as your microwave, cell phone, most portable telephones and a lot of other radio based equipment. At my house we have a Sony phone which jams all frequencies to contact the handsets when the phone rings. Took me a while to figure out why whenever there was a call I would be DC'd. I ended up taking all the portable phones, putting them next to the antenna and paging the base from the handset. Found out which phone caused the problem.
heh, my phones do that too, pisses me off
Didn't try all the stuff you listed, but I was messing around on the laptop we have, and turned on the setting which allows other computers to receive internet through the laptop, and suddenly the internet works fine. I forgot to mention earlier that the laptop internet always works fine. My computer isn't reading the info from the router or what? o.O
Edit: or it was an odd coincidence
I'll do all that suggested stuff tomorrow when I have time
