Tag: fonera 2100

Sometimes pocket money isn’t enought for buy new network devices or we want to save some money changuing no existant money for personal time. In my case I needed to create a wireless bridge in my personal network, pass a ethernet wire between two builds wasn’t an option. Searching in my forgoten stuff boxes i found two foneras model 2100. Fon’s firmware isn’t powerfull enought to get wds and when these things happens Free Software is our solution. I’m a lucky man and I also found a usb to 3,3V serial adapter, one of my superpower is that i can brick everything. First of all we need to plug our serial adapter into fonera’s port, check the attached image for see jtag pinouts

when we have our jtag port connected we need a software for send data over jtag in my case i use GtkTerm.

in debian is simply I open a root terminal and I write

apt-get install GtkTerm

in the same term i write

gtkterm

I use a root terminal because I don’t want waste time configuring /dev/ttSy* permissions

next step is configure port speed 9600,8N1

in GtkTerm menu select configuration/port and fill data boxes, in my case port is /dev/ttyUSB0 if you don’t know your port a dmesg output can be helpul.

now is time to plug powersounce on our fonera and see output.

must be something like this in our gtkterm

we need get access to redboot console  you only need un plug and plug powersource to fonera and press continously ctrl+c until you see

RedBoot>

we need download ou firmware go to
