[Solved] Wireless Network Connection doesn't have a valid IP configuration

Recently I had to replace my 3 year old Netgear JNR1010 N150 router with TP-Link  TL-WR841N the task seemed pretty easy as configuring a new router should be not a big deal I thought, however the show was not a easy one, otherwise this post wouldn't  have been written at all. The first problem was that my ISP allows me to connect directly only on one MAC address, this huddle was easy to get through just a call at customer care and they made it free for some time and allowed me to connect the new router and assigned the new MAC address to my account. Going by the instructions I was able to configure my router for PPPoE account and validated the same on my Android phone. However, when tried verifying the same on laptop I got below error once problem was diagnosed by Windows.
