i want to upgrade firmware via tftp in mm2211. but i am not getting the reply from the routers gateway. also i am not able to open the default login page of the router, so i have gone through a few websites and would like to know the following.
1) where is the jtag port on 2211.
2) where is the serial port on 2211.
3) does anyone have a step by step guide on how to connect a serial console to 2211 and then do a tftp and flash the original firmware.
please note that i have tried every type of reset from holding down the reset button to 30-30-30 reset and so on but nothing works.
