Thanks for your inputs dashanan....but i think WiMax is different from USB modem, right??

And USB modem connections are not efficient from any service provider, whether Reliance, Tata or Airtel. I have tested it!!

Also, I won't say sify is the best/better/good because i have to call my net operator every noon to get my connection working since its giving me problems for past 2 months.
Sometimes its the hub on the Pole, the wire is disconnected, a crow sat on the wire and bit the wire off....and such stupid excuses i get from the net operator which i seriously doubt are even true.

And to top that, Sify CC is not at all helpful, its similar to Reliance CC so not at all useful!!!

Anyways hoping for best with this WiMax service!!!

cheers!
