Max Speed for 2.4ghz is half Archer A1600
I purchased an ax73 router to replace an older Billion we were using as an access point off the Archer VR1600v suplied by our ISP, TPG
The VR1600v is Hardware v2, Firmware 0.1.0 0.9.1 v5006.0 Build 200810 Rel.53181n and obviously it is maintained by TPG.
The New ax73 is Harvware v1 Firmware 0.1.0 0.9.1 v5006.0 Build 200810 Rel.53181n
We had to set the new router up as an access point because my wifes work laptop is windows 7 HP elitebook and couldn't see the SSID in her wireless connection manager.
I beleive the problem there is updated wireless driver.
However in debugging the issue with inSSIDer i find that while the VR1600v 2.4ghz max rate is 300Mbit but the ax73 as an access point only provide 144Mbit max data rate.
I tried unsetting some of the smart new features in the ax73 like the combination both 2.4 and 5ghz networks.
So while I may be able to get my wifes work to upgrade or replace her computer she's actually better off connecting to the ISP supplied VR1600v
