Asked By 20 points N/A Posted on -

I accidently pressed Reset Button on my D-Link 2750u DSL Router. All the setting got erased and now I am not able to Access the Internet. The DSL always blinks and doesn't get stable. Internet Light is RED all the time. Please tell how to configure it with MTNL as my ISP. I want to access the Internet. Due to Diwali Holidays their office is closed so I can't go to them. Please Help.
