Hello friends
I am looking to upgrade my Nokia Siemens Network C2110 Adsl modem firmware because there are many feature missing in this model and I think upgrade will provide some good features. But searching online I was not able to find any upgrade for this firmware. THis modem is very old and I think there should be firmware upgrade available. I had got this modem from BSNL but I can't find their site to do the upgrade.

Please help friends.
