Thank you for your response.
1. I tested with both 2.4 and 5ghz, as well as I tested with the ethernet cable. With 2.4 ghz I was getting less than 30 mbps, with 5ghz I’m getting less than 40 Mbps and with Ethernet cable, I’m getting 85 to 90 Mbps.
2. I tested from my laptop, using wifi and Ethernet cable both, I mean tested with wifi, then with cable. I also tested from tv where I installed a speed testing app, though I connected the tv with an Ethernet cable. I also tested from iPhone.
3. I connected with wire and took this screenshot.
Appreciate your help.

A couple things.
1. your ethernet connection is only showing 10/100mbps. Not gigabit. So not sure if your device doesn't support gigabit or if you have a sketchy ethernet cable (poor quality cables can cause it to drop from gigabit to 10/100mbps). so try a different cable or a device that supports gigabit
2. most tv's aren't gigabit because they don't need it. 4k streaming only takes 25-40mbps so most manufacturers don't include gigabit and just 10/100mbps because they don't need them. so your tv isn't trusted
3. your 2.4ghz seems about right for that device. 2.4ghz is a slow network and sensitive to interference.
4. your 5ghz seems a little slow. What device are you testing 5ghz on? have you tried changing what 5ghz channel you're broadcasting on?
