I purchased this TPLink Wifi Router device on 28 March 2019. After using this Wifi Router, I am getting very low internet speed on my Laptop/ Desktop. But when I use LAN cable, I get full speed. So the problem is with TPLink hardware device and Support of TPLink is not accepting this. It should come under warranty period. I want to get it replace with new and working TPLink Router immediately. Otherwise, get my money back anyhow.
I have wasted so much time to fix this issue, but it did not resolve my problem.
