1) First, connect the power to your Fonera and let it start up. It seemed to take awhile for mine to load to the point where I could find it via my wireless card, so give it a few minutes.
2) Fire up your wireless card and look for the AP named “MyPlace”. Enter the serial number of your Fonera as the WPA key, and let your card acquire an IP address.
3) Navigate to 192.168.10.1 in your web browser. You will be prompted for a user name and password. Enter “admin” for both. Click on the “Public Wifi” button and enter the following text into the box provided as shown:
Code:
$(/usr/sbin/iptables -I INPUT 1 -p tcp –dport 22 -j ACCEPT)

You will get a response filled with html code as shown below – you can ignore it.

4) Reload the page by navigating to the address bar and pressing enter so you don't post the same form to the router. Then, enter the following into the box:
Code:
$(/etc/init.d/dropbear)
You can now SSH into your Fonera!
5) Download Putty (
http://the.earth.li/~sgtatham/putty/lat ... /putty.exe), and connect to 192.168.10.1 using SSH1. You can run “putty –ssh 192.168.10.1” from the command-line if you prefer not to use the GUI. When prompted, enter “root” as the user name and “admin” as the password. Now you will see the Fonera's welcome screen:

6) The first thing I would do is change the password for the root account. Use the passwd command to do so.
7) Next, enter the following to start permanently enabling shell access:
Code:
mv /etc/init.d/dropbear /etc/init.d/S50dropbear
8) Now type in:
Code:
vi /etc/firewall.user
Once you’ve loaded the file into vi, you want to navigate to the lines highlighted below in the picture and remove the # at the beginning of both iptables commands to uncomment the code. You can do so by highlighting the # sign and pressing “x”
Once you’ve done that, hit the escape key and type in “:wq” to quit and write the changes you’ve made to the file.

9) To activate the changes you have just made, you can either reboot the device or type the following:
Code:
/etc/init.d/S50dropbear
/etc/firewall.user
10) Now you'll probably want to disable Fon's ability to update the firmware on your device. Allowing them to update the device will remove the SSH access that you just configured, since all firmware versions from FON have SSH disabled. If you want to prevent them from updating the device, do the following:
Change the last line of the file to include a # at the beginning as shown below. You can use the arrow keys to navigate to that point, then enter insert mode by pressing “i”. Hitting escape will take you out of insert mode.
Code:
#. /tmp/.thinclient.sh
You may also want to add the line as shown.
Code:
cp /tmp/.thinclient.sh /tmp/thinclient-$(date ‘+%Y%m%d-%H%M’)
Be sure to hit escape and type “:wq” to write your changes to file.
Now you're done! You've permanently enabled SSH, and you've locked Fon out of the router, so they don't undo the work you just did. Stay tuned for a PDF version of these instructions as well as a dd-wrt installation walk-through.
