I’ve bought a router in April-2014. For the first 2 months it worked well. From June onwards the speed varied and also 50% of the time I am not able to connect to the network and see often get the message "Resolving Host".
Despite many complaints(Phone calls/e-mails) the issue hasn’t been resolved.
I was Airtel’s Broadband customer for 4 years and even the service was good but 4G service is pathetic.
