Hi Folks... I have got a secondary remedy for my issue which I posted under this blog about a WiFi error. My N9 was giving me this error when I try to connect it to my main network router like I have connected my Laptop. So applying a simple logic, that my Laptop works perfectly fine to connect to the main router, I have created a Ad-hoc or WiFi hotspot in my Laptop which is discoverable by other WiFi devices like PC, Laptop and Mobiles.

.... Now my phone is connected to my Laptop network via Ad-Hoc sharing option.. and works much faster as the laptop is much closer than the router.... Now I can patiently wait for PR 1.3 hoping it wil still fix the WiFi and Connectivity bugs..
