I would suggest Reliance Broadnet(WiMax)...
Are you really using Reliance Wireless Broadband service?
@ Karthik
Please don't even consider Reliance WiMax based internet,
We are using it in our office.
* Down times are little frequent,
* Technical support is poor each issue needs at-least two days for it to be fixed.
* They don't have enough local people to provide instant on-site support,
I suggest BSNL Dataone or Airtel Broadband if you can take one,
I am using BSNL Dataone in B.T.M Layout since around two years and their service has been vastly improved.
Reliable speed. (No-less, No-more)
Down times are very rare,
Customer support also improved much after they switched to 1-800-424-1800 .
BTW which stage are you from 🙂 i am in second stage.
