Is SSID on the modem
If you live in Italy (like me) and your ADSL is provided by Telecom Italia, then you probably got this wireless router as a welcome gift.Initially I though that it is, like any other router provided by the phone companies, a castrated version of a badly working modem. Therefore I just put it into its box and away.
However lately my usual router stopped working and as I needed an immediate substitute, that gift came in my mind. When I started configuring it through its loveless GUI I felt confirmed in my aversion against it, however when you're willing to invest a bit more time into it you'll find more and more options present in Netgear or Fritz!Box routers, just badly presented in that awful GUI.
You can have DynDNS, Port-Forwarding, 256-WLAN-encryption, Print server via USB... so basically everything you need...
So, basically I had to change the name of it. Simple you guess? Me too, however there is no option to change the name of the WLAN in that GUI which was really surprising me, but there is a solution to that problem too.
Basically just create a backup of your routers settings using the GUI, which will be saved as something like "AGConfig20121212.kry". That one is an encrypted version of the settings which we are going to decrypt using the following command
openssl aes-128-cbc -K 30 -nosalt -iv 0 -d -in AGConfig20121212.kry -out AGConfig20121212.xml
In the XML then you can just search for the name of your WLAN and change it to a name you like it to be. After that we need to encrypt the changed file using the following command (note that "-e"(encrypt) now changed to "-d"(decrypt) and the filenames are in reversed order)
openssl aes-128-cbc -K 30 -nosalt -iv 0 -e -in AGConfig20121212.xml -out AGConfig20121212.kry
Now you can just restore your router with this newly created file (pay attention on your power supply during that action) and provided that you did not change any other values in the file, your router starts up in the same configuration as before just with a new SSID.
