Here is a picture of the router's board.
Which ports are for JTAG (serial is J3)?
The WIKI has nothing for this BELKIN router.
There is no guide for JTAG concerning this router in the forum. (I checked)
This thread will help others once the fix is found.
I am looking to edit the wiki for this board and make a diagram like:
So:

That I wouldn't be able to answer. May have to wait for someone with some more experience with JTAG. _________________ Peacock Thread-FAQ -- dd-wrt Wiki
The 14-pin solder pad field does surely conform to the mips jtag standard.
Pins 13 and 14 are of no interest so some other router mfgrs has reduced the field to become 12-pin by removing these 2 highest numbered pins.
I don't think you need to do a wiki entry for this, it is helpful for routers which doesn't have a solder field and where someone then has found out where you can connect your jtag wires.
Pin 11 nSRST is also rarely used and pin 12 is no connection so it is possible to reduce the solder field to 10 pins.
My guess is that the 10-pin field near to the radio chip is such a reduced thingy for jtaging the radio chip.

ty I got the grnds (easy to trace out) but the rest of the information helps greatly.
After school tomorrow I will dive into this some more.

Ok I have the holes cleared of solder. I am ready to solder in the connections. how do these connect to the DB25 male end of the cable to be plugged into the pc?
The Jtag article in the wiki fully explains how to make a jtag cable. _________________ I fix "shortcuts". If you don't have time to read thoroughly, I don't have time to re-type what you missed.
