I have a bricked WRT54G v1.1 LinkSys router. Can anyone tell me were I can get a JTAG cable and TJTAF software to un-brick this router? Question

I reflashed a bricked WRT-54G V3 years ago with HairyDairyMaid software and a PC parallel port JTAG cable. I did have to solder the DIP header socket on to the WRT-54G board. I would expect the software utility will allow the use of a USB JTAG such as the Altera Mini USB Blaster Cable Programmer common on Ebay

Fwiw, it's pretty easy to build a JTAG cable if you have access to the resistors and connectors. DD-WRT wiki's have various JTAG and recovery info too:
