Can anyone specify an actual JTAG pinout for Linksys E4200v2/EA4500 router? The EA4500 and the EA4200v2 are actually identical hardware. There is unpopulated 8-pin JTAG header on PCB, 4x2 rows. This Cisco/Linksys switch has a DB-9 male console port and I dug out a female-to-female DB9 serial cable, but I have no idea whether it's a null modem cable or not and it doesn't seem to work using the official serial port settings for the SRW2024P.

upgraded MW to 1.30 - maybe things are slightly less broken

Maximum Performance Dual-Band N Router

• Support page • (Template link outdated)

'3763-40700105R' and the Cisco logo is silkscreened on the board.

This router uses Galtronics antennas.

Note: Three antennas are used by the 2.4 GHz radio, but it's still a 2T2R radio.

The default SSID pattern for this device is CiscoXXXXXX on both bands,

where XXXXX is the last 5 characters of the serial number.
