Hi. Currently I am using Asus RT AC1300UHP router.

However due to dk what reasons, my router is on first floor and my smart TV is on ground floor. I can say the internet speed for my smart TV is really slow and can hardly load a youtube video. Do I use mesh wifi or powerline ??

Besides, I am using a very old TM modem which I dont know if they are supposed to change it. I am currently running on the 300 Mbps speed and I am getting approx 300 mbps on my phone on the 5Ghz band but 5Ghz cant be received on the ground floor

Speedtest on 2.4Ghz on my phone shows 30+ Mbps... I downloaded a random speed test using my Sharp LC50UA6800X tv, found out the download speed is only hovering around 2 Mbps smhh
