Very dissapointed after getting this product for the first day and first time. 

Expecting it can help to improve the speed and stabilize the connection, however ended up disconnecting and slow down my speed.
Saw TP Link Admin shared a thread of guide, followed everything still slow and disconnecting in games. Very unable. --> without extender. im stable and ping are not jumping
Below are the screenshot as requested for both extender and router speed.
Im praying hard not to waste any money and ended up with bunch of  guides and tips provided by ADMIN that cant solve anything. 
Kindly provide a help that can satisfy your consumer and make your product valued.

With RE200 Extender:

 

With Router only:
