Hi everyone,  just bought 1 AC1750 RE450, 1 month ago, everytime im watching youtube video or downloading something from Steam or watching Twitch, im getting connection lost, like my internet is gone for like 5-10 seconds, i tried everythign i can thing :

- I called my internet company and verified everythign is okey, they changed my router to a better one to see if everything is fixed.
- I tried to connect my rotuer directly to my computer to check if the connection is lost, but nothing happen, everything is okey.
- I updated the firmaware to last version.
- I call tp-link support and they said go to your store and use the warranty, i did it and today i have a new one, but still haveing the same problem, i don't know what to do.
In the tether app, check the range of router to see if there is a good distance bettween, and the app is okey for it, it is aprox 6-7 meters between Router and tp-link RE450, and there are no walls in between.
Im desperate, any help or advise on what tp-link to buy to solve this problem.
Thx in advice,
