I'm a very tricky situation,i'll break it up to make it understandable...1.I've been using BSNL Broadband from around 6 years and that is why i've got a very old model of modem (R.B.Comtec X7005Q).It is a DSL modem that requires user/password.2.It came with an installation CD that works only on Windows XP (not in Vista..not in 7). I've tried o search for its newer drivers but its not available at all.3.Now i'm thinking of switching to a Wifi modem but i'm afraid because of my outdated connection that won't work on my PC...any ideas on whether i'm right or wrong...its very urgent...!!
