Asus DSL-N10E Wireless-N150 ADSL Modem - Link and connectivity problem?

Hey, few days ago i just ordered a new modem for me from online retailer flipkart. The modem name which i had ordered was Asus DSL-N10E Wireless-N150 ADSL modem, it was working well for 2 month and now suddenly it has started giving a big problem like it lost connectivity all the time not supporting wifi. Actually earlier i thought this problem was from BSNL side but they check out the whole line and my connection with other device and it was working well.

So, i want to know that what should i do now. Please help?

Why don't you get your modem checked with company , may be device has developed problem. Sometimes WIFI devices gets weaker.. sometimes due to time or due to fault in device. I think if its new you can ask for replacement or service / repair for it.
