Model: Archer AX90  
Hardware Version: V1
Firmware Version: 1.0.6 Build 20201020 rel.75204(5553)

I have Comcast as my ISP with 1GB service

 

MODEM:

Arris Surfboard DOCSIS 3.1 

 

ROUTER

Model: Archer (AX90) AX6600 Tri-Band Wi-Fi 6  

Hardware Version: Archer AX90 v1.0/v1.20

Firmware: 1.0.6 Build 20201020 rel.75204(5553)

Smart mode off

Tri-band enabled

Channels set to Auto

 

CLIENT

Model: 2020 MacBookAir M1 with MacOS BigSur and a 802.11ax WiFi card.

 

Anti-virus: turned off

 

PROBLEM

AX wifi download speeds dropped drastically when measured using speedtest.net with speed dropping on other bands as well.

 

870 Mbps down - Cat7 plugged directly to modem

720 Mbps down - Cat7 plugged directly to router port (via Cat7 to UBC-3 adaptor)

450 Mbps - 5GHz-2 (ax only) - client speed next to router 

200 Mbps - 5GHz-2 (ax only) - client speed 25-feet away in next room

 

Upload speeds same across tri-bands at 38 Mbps to 40 Mbps.

 

I WANT TO SOLVE the 5GHz-2 (ax only) download speed issue. The Archer (AX90) AX6600 Tri-Band Wi-Fi 6 is NOT performing as advertised.

I changed the 5GHz channel to 44 and it cleared up the speed issue. Now my Wifi speed matches my ISP service speed.
