Of late I have seen a lot of third party providers of Reliance Wimax connections in Hyderabad posting their phone number on my blog entry Going WiMax . The wimax connection really did not work out for me for the following reasons It just took a lot of time to get a connection each time I wanted one. It would sit for ages in trying to acquire network address. The speed was decent but nothing like the 2 mbps link that Airtel currently gives me. It was not really reliable. It would get cut of for no reason what-so-ever. On the whole my experience has not been good at all with the wi-max connection and had it disconnected. I now use Airtel which is completely underground in my area and the service that they offer is quite exceptional. Speed is good and I have not experienced any downtime in the last 1 month that I have been using it.
