Hi Mayuresh,

WiFi Analyzer<https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer>android
app (free) gives you understanding of radio pollution as mentioned
by Pranav.

problem finding can be divided into three parts

1. Problem with environment
- Replacing router(1) with any other router (router 2, preferably Lava 150
) does not solve the problem.

2. Problem with configuration
- Different Lava 150 (borrowed from contacts etc.) router works well.
Replicating those configurations in your router makes your router start
working.

3. Problem with router hardware.
 - If its not 1 or 2, most likely its a faulty piece issue.


Best Regards,
Rav!kant
