I'll buy a new ethernet cable and test it again. Why 5g is slow? I tested from two computers, and iphone.
Thanks
tough to know off limited info.
saying 2 computers and an iphone is like a mechanic asking what vehicle you have and saying its a car and a truck.
Details are key. What wireless cards are in the computers? What iphone is it?
Did you try changing wireless channels? Try the higher 149+ 5ghz channels
How far from the router are you testing? 5ghz speeds drop quickly and don't broadcast through much materials
I think I figured out the issue. I think my tv was causing internet slowness. I don't know how or even that's possible, but today I moved my modem/router from the living room to another room where I work. I thought cable is faster than wifi so I'll use a cable with this router till I'll able to fix this one or buy a new one. So I tested internet speed it was close to 300 Mbps with the ethernet cable. I tested 5 g from my phone it was close to 150 Mbps. I tested the tv, its speed was 143 Mbps. The modem is about 30 to 40 feet away from the living room. the living coaxial cable was fine, these cables were installed recently.
Thank you for helping me to figure this out.

How was the TV connected? Most TVs with a wired LAN option are limited to 100 Mbps. That's fast enough for anything thrown at them.
Wifi speeds are never a reliable guide to what a router can deliver. It depends on the technology in the wifi client. These never reach the same speed as a wired connection, especially 2.4 GHz wifi devices.
