I setup my new Archer C2300 router to the default settings and when logging in from my iPad it popped up a message that said WPA/WPA2 (TKIP) is not secure. I went to the Wireless\Wireless Settings...

My router is located at an outside corner of our home's living room, consequently the signal has a number of walls to go through to get to the far diagonal corner of the house several rooms away....

This was originally the case but TP-Link renegotiated with the contract and it is now lifetime for all original owners and current/future owners.
