Upgraded router firmware... now dead

I recently upgraded my firmware through hyperterminal and now the router will not even turn on the WAN. The LED for the LAN connections are still on but nothing else works. I cannot ping the router or access it through hyper terminal. PLEASE HELP!!!!!
 
If you can't even console into the router (what kind of router is this anyway) then you're screwed. Call the manufacturer, see if there's a way to reset it so that it like reads a hard coded stored copy of the original firmware and boots from that. Or, so that it will read boot information from a bootp server, and then read the firmware from a tftp server. However if it's a cheap home DSL/Cable router, you're probably screwed. Probably need to replace the chip if it's made like a motherboard BIOS or send it in for service.
 
Did you try connecting through the serial port on the router yet?
When the network connection goes to hell the serial port is there to bail you out.

Most of the new routers have a "service"-serial port to fix the exact thing your talking about, it's a failsafe backdoor into the router.
 
I assumed when you said access it through hyperterminal, that you meant using the serial console port. Obviously if you can't ping the interface anymore then telnetting through hyperterminal isn't going to work.

If you can get an interface via the serial port, then you should be able to flash the firmware again. (Or just make sure the configuration wasn't reset to defaults or something.)
 
With my Netgear, I have screwed the firmware flashing a few times and used serial to get back. The backup when I flash my router was that it accepted an xmodem transfer, without doing anything else. I would just connect via com1, and reupload via xmodem and I was set.

Your router may have something similar, but I dunno.
