I have MTNL adsl 512 unlimited 1500rs plan. My Internet does not seem to work most times, I have tried playing around with the settings too. At first I kept obtain ip add and DNS add automatically. Then Mtnl asked me to enter 192.168.1.175 DNS 203 95 227 70Everytime I restart my computer the Internet starts but then goes offI have a Vonage device which works perfectly via the same modem. Please help resolve as my network knowledge is limited
