I am using this router since 1 year. it comes with 1 year warranty. I never encountered any network and connection problem. I am using 1 phase router which covers 600 sq ft area and 2 phase router which covers 1200 sq ft area. The price ranges from Rs.1000/- to Rs.2500/-. it delivers transfer rate of 150 to 300 mbps. you can do video streaming, online gaming etc.it become 2 times obsolete till now but because of warranty I am relieved from payment.
