Hi,
Few days back, I subscribed to Tata Indicom Broadband ( www.tataindicombroadband.in ). I chose the Infinity 1 Mbps plan. This apparently comes with no installation charges even if you don't give commitment for more than 1 month. For other plans you have to commit for 4 months to get that 1K INR waiver. I found that they do the feasilbilty quite fast and response time was quite fast as well ( this might depend on locality). But co-ordination between the tech and marketing dudes was not so good. Oh and neither of them knew if they supported Linux :O. Surprisingly the callcentre dude confidently said they do and the tech dude would setup everything when he comes to my place.
Cut to my home ( few days later, i.e. yesterday ) - the tech dude arrives. When I tell him that I have linux on all the boxes he made a few calls and finally said he doesn't know how it works on Linux but he will get a mail from his boss and will come back and do the setup. After some random conversation, I asked him if he can do the setup on Windows atleast and he managed to do it on my windows partition in my laptop ( yes, I didnot delete it yet :).
The general process these chaps follow is - login to some webconsole of theirs where they find data about the customer - go to the tata indicome bb website and register with the Serial number and PIN code. After which you have to select your username, password and the usual cruft. Then the create a account on your box and check if everything works and leave.
The Linux way works much faster :). I followed [1]. But all that is needed is "sudo pppoeconf". If you already have a /etc/ppp/peers/dsl-provider, back it up if you care for existing settings. After that is mostly selecting yes or no. For user name - please select username@vsnl.net or whatever domain they have given you. But point being the complete userid+domain has to be there, afaik. Type in your password. ( when the dudes set it up, they generally put passwd as tata123, change it using the website )
Don't know if this is worth adding into the wiki. Maybe it should be,
