I just purchased this router and it has been a complete dissapointment from the start

I have disabled 2.4 and MLO and use just the 5 and 6ghz bands with the same SSID. (seperating it didn't make a difference in any case)

My iPhone 16 connects just fine over wifi 7 6ghz and gives me about 930Mb/s down

My iPad m4 and MacBook m3 both of which have wifi 6E when connected automatially to the 160mhz 6Ghz gives me a rediculous 200Mb/s down and even the upload is capped at 10mb/s. According to the wifi diagnostics, the negotiated rate is 2401Mb/s with very stong signal strength.

In wifi settings on all devices, the "wifi 6E" setting is set to automatic so it connects automatically to 6ghz instead of selecting 5ghz

If I force it to use 5ghz via the tp link app, both the wifi 6e give me a decent 800Mb/s+

However I didn't buy a 6ghz router to use it on 5ghz exclusively

Can someone suggest what could be wrong otherwise its going right back to the supplier.
