I was flashing the router with the Tomato firmware, but something went wrong; I'm not sure what. Now, the router responds to ping at 192.168.1.1 (my Mac's on a static IP 192.168.1.21), but the web-interface doesn't come up.
I have read that this situation is recoverable in a [couple of places][2], but I haven't been having much success and so I wondered whether anyone could help.
From my Mac (OSX 10.5) I have tried to tftp a new vanilla-Linksys firmware to the router and reboot; according to the trace, this sends it but the router behaves no differently after a reboot.
I've read that if boot_wait is turned on, I'll have an easier time, but I haven't been able to find any instructions that tell me how I can tell whether I did this or not (I don't think I have, but I might have, when I tinkered the first time months ago – the router has worked since then, though).
I have found a couple of references to [something called JTAG][3], which seems like some kind of [homebrew diagnostic cable thing][4], but that's a little beyond my ken. Happy to try it, with muppet-level instructions, though (I do software, not hardware!).
So, I'm at a bit of a loss, really, and wondered whether anyone could provide me with the route (ha. ha.) out of this mess?
Hm, I can't post all the links I wanted to until I have some more reputation.

Have you tried failsafe mode. http://wiki.openwrt.org/oldwiki/openwrtdocs/hardware/linksys/wrt54gl
Check your arp cache. I found the openwrt pages useful for a similar problem.
Also note references to problems with the power supply. Everything seems ok but system doesn't come up. I swapped in an old power supply temporarily until I could order a new one.
