I've been using bsnl wimax for past few years. I am facing lots of problems like slow speed, frequent network dropping, connection breakdown and poor support services. It drops the connection quite oftenly almost 6 to 7 times in a month and when I complaint against that nobody tries to help me out. They don't provide me right services, guidence and assistance. They hardly send their technical support staffs whenever I face any technical problems. They always make lame excuses that no one can buy.
