@Leo_H Hello all I am also seeing this issue with AX1800 router and AX5700 Mesh. This is an across the board issue with TP-Link and I am returning both of them. C

@CHUHY My wireless device that I use to test is iphone 12 Pro Max. The app that I use to test on the phone is Speedtest app and on my wired desktop is via the same Speedtest.net site. Phone is right...

Here is the problem. I have 400/400 Mbps from FIOS. I am able to get the full speed using wired connection. but for wireless connection on either Wifi 5 GH band 1 or 2, I am getting 400 mbps download...
