After having it sat in a box for 4 months, waiting for me to fix it, I've finally fixed my wireless router. It's a
Netgear MR814v2, and it is, quite frankly, a pile of poo. But it was cheap, and it does the basic job of unencrypted wifi perfectly well, so its enough for me. My problems began when I realised that someone in my flat at uni was packet-sniffing me. Not a huge problem, I don't really have anything to hide, but I thought I'd set the Netgear pos to use wep and keep him out. Now I'm not sure if I set it up right, but got the key wrong, or set it up wrong, or if it just didn't like the idea of running wep at all and crashed. I suspect the latter, since it became unresponsive even to wired access.
Netgear handily provide a little factory reset switch on the back. You're meant to be able to hold this for 10 seconds, and have it reset everything and greet you with the setup wizard. I tried this, many, many times. It appears that my switch is broken. I finally managed to reset to factory defaults by opening it up, and grounding the leg of the reset button. It would have been so much nicer if they'd put a jumper on the inside, the way most pc bios's get reset. Ah well, live and learn. I don't think I'll try wep-locking it again.
