@amit07If you explain that you want to use two laptops in WIFI mode to Airtel CC , they may exchange the present modem for a wifi model 450BX1. Being Festival season, they may replace the modem ! Try your luck .Also complain . that because of USB mode you are getting frequent disconnections !Their latest Beetel110BX1 does not have USB PORT ( given to me recently).I am using it along with Netgear WGR614v6 WIFI router for two laptops. and Vonage VOIP.
