There was a question that I posted here [https://networkengineering.stackexchange.com/questions/65695/lan-speed-150-200-mbps-but-wifi-speed-is-5mbps-to-80-mbps] , which was off-topic. Hence I found out that this is the right place to post it.
My initial question was this.
I'm having a 150 Mbps GPON Network.The modem has a 2.4 Ghz Wifi inbuilt, but I am using a TP Link Archer C20 Dual band Router v4, to get the 5Ghz band connecting the Ethernet Cable.
When I use Ethernet Cable Directly in my laptop, it is giving me from 150 Mbps to 200Mbps. But when I connect it using the Wifi, I am getting a measly speed of 5Mbps to 80Mbps.
I am using a CAT5E LAN cable of the connection which supports 1000Mbps.
I have gotten 100 Mbps with the same router, and the router has around 433Mbps bandwidth for 5Ghz network alone.
I was told there will be some attenuation, but this seems to be a lot. My speed is lesser than when I had a 100Mbps connection. Could anyone tell me, if I have to change any particular settings at all?
I found out that, my router event though has the following bandwidth of 5GHz: Up to 433Mbps and 2.4GHz: Up to 300Mbps, I missed the fact that it was not a Gigabit Router.
So, I bought a low-mid range Gigabit Router, D-Link DIR-841 - AC1200. The speed is not very satisfactory, infact less than 100Mbps at most times, but I found out that the upload speed is faster than download speed, every single time, even though my internet plan has higher download than upload. The Ethernet is seemingly fast, and an average of 150-200 Mbps.
I tried switching to 802.11ac mode to see if there is an improvement.
Before starting to write a question of my own, I have seen articles like this [Why am I not getting full Gigabit Ethernet speed in my LAN?
I see that Wifi is half-duplex and cannot provide higher connection but still, can anyone please suggest a proper configuration for the same, in order to improve the Wifi speed? Or maybe a better router model?
