I have a LG P690 mobile phone which is about one year old. It is connected to Wi Fi at my home. Service provider is MTNL. Modem is 450TC1. I have the following problem:

Every time I try connecting mobile to internet, I get a message that Wi Fi connection is not available. After this, I connect mobile to whichever signal available and then again connect back to my Wi Fi connection. With this exercise, I start getting the signal. I am required to do this every time I need to connect to internet.

My laptop is also connected to the same modem. It works very smoothly without interruption (for more than 2 years).

Request for your help.
