BSNL FTTH Rs.777 plan (100 Mbps till 1000 GB and 5 Mbps after 1000 GB + free Hotstar premium)
I am using BSNL FTTH Netlink HG323DAC version 1.3 ordinary modem. Plan details are : Rs.779 plan (100 Mbps till 1000 GB and 5 Mbps after 1000 GB + free Hotstar premium)
When connected with 5 GHz, my Samsung A9 pro 2016 device connects at 370 Mbps WiFi speed so that I am getting exact plan speed in the speedtest.net app.

But my Samsung A9 pro 2016 or any other device is connecting only at 65 Mbps WiFi speed in the 2.4 GHz band and the speed test app shows less than 35 Mbps each for UL and DL even though the WiFi speed is 65 Mbps and not sharing the connection. I am getting above 95 Mbps each for UL and DL when tested on laptop with 100 Mbps LAN. But same problem occurs like my A9 pro even if laptop is connected with WiFi.

My questions are 1) Why do the devices connect only at 65 Mbps LAN speed in the 2.4 GHz? ; 2) Even if it connects at 65 Mbps, why is the speed less than 35 Mbps each for UL and DL? ; 3) What is the maximum supported speed in the 2.4 and 5 GHz bands (if the signal is 100%)?.

This is normal and expected from 2.4 band.

Vishal Rao :
Do you know about the maximum supported speed for each frequency?
You'll have to check online as I don't know the specs but what I have seen is max 72 mbps link speed on 2.4 ghz band and 866 mbps link speed on 5 ghz band, and on top of that the actual data transfer speed is around half the connection link speed.

Yeah I guess if both router and client device support it then speed can be multi gigabit on wifi AC 5ghz band, but with all my devices so far I have only gotten 866 max and I have mostly mid range specs.
