Bests & Worsts Reviews from Amazon

I have a a 400mbps internet connection thru Suddenlink. This router will put out the 400mbps speed on wireless and the range is fantastic. But, after a few hours the speed will slow down to about 50mbps. After a reboot the speed returns. But again, after few hours the speed falls back. I have my router programmed for a reboot everyday. Apparently TP-Link recognizes the problem but has not been able to fix it. Otherwise, very easy to set up and the speed and range when it doesnt slow down is fantastic. Update 1/31/2020: went back to my second home after about 8 days and my ring ring doorbell had quit working because of no internet connection. I checked the internet speed and ookla said it was -0-. I unplugged the power and waited about 5 mins and plugged it back in. I after the router connected to the internet the speed was 433 Mbps. I had programmed the router to reboot everyday which does not work, to restore functionality power needs to be disconnected. I disconnected the router and brought it. I reset it per tp-link instructions. I then hooked it up to my internet at my main home and found all 4 Ethernet ports no longer worked. I then packaged it up and sent it back. I really wanted to love this thing, it is amazingly fast but it simply does not work.
