Hello , I am a new user and I have applied for MTNL 848 NU. I have opted to purchase an adsl modem. Which is the best among D-Link -502t ,airtel-beetel 220x and Linksys am300 . I am sceptical about d-link due to past experience with lan router.I have a few queries1) If I choose to use bridge connection wherein i manually start the connection from windows (the modem will be left on 24/7) is it still necessary to switch on & off the modem physically at 12:00 midnight to avail unlimited access as instructed on mtnl website2) worst case scenario if for some reason my pc hangs and it fails to shutdown/or i forget to switch off modem at 8:00 am ,all the data downloaded from 12-8am will be billed. Is this true? pls help
