Low wifi performance of WPA4220
I have a TL-WPA4220 KIT and two additional WPA4220 wifi in the house. Also I have a 94mbit internet line. I am having very low wifi speed with these weird devices. Here is how;
When I am connected to any of these WPA4220 wifi devices with an ethernet cable, I get 85mbit speed which is pretty good to me. So electric line is fine.
When I am connected to any of these WPA4220 wifi devices with wifi, I get max 15mbit which is a disaster to me. They say these are 300mbit wifi devices but I doubt it. Just these devices are bad.
By the way, I have a new computer with a good wifi on it. I get 87-88 Mbits on 5Ghz and 52-55 Mbits on 2.4Ghz. So my computer is fine too.
So, is there anyone who gets 40-50 mbits on wifi with these devices?
Tp-Link support line here doesn't know anything or doesn't care at all. They said devices might have problem and they want me to send them in. They think all 3 devices might be bad. Statistically impossible! And I am sure devices has nothing bad at all, just they low speed, devices and they don't do what they are supposed to do!
Probably i will never buy these things again. Looking for other options.
