More on this.

I installed inSSIDer on a windows 10 desktop with a archer ax3000 in it.

The max on the 5g wifi went up to 2041Mbit and the max on the 2.4g went to 238Mbit still less than the vr1600v 2.4g at 300Mbit however The 5g on the VR1600 is 1300Mbit

I installed inSSIDer on a brand new M1 Macbook pro and it had the same as the 2012 Macbook pro 144 2.4g and 1733 for 5g

As a smart connect with both 24 and 5g bands combined it just lists as 2041Mbit

Regardless of what inSSIDer reports as the max throughput if i do a TPG speedtest via wifi it says my connection is 70-80Mbit with an upload of 12-15Mbit

If i do the same test on a wired connection i get 250Mbit down and 20Mbit up. Here's two screen prints showing wireless and wired.

I'll look at it all again when they pump out some new firmware for his router.

@Kevin_Z I was able to get my wifes laptop wireless driver updated by pestering the desktop support guys. She now sees the new router wireless. That will be a common issue with this router.

I realised why the VR1600 has a higher max data rate on the 2.4ghz band it's because it uses 1 +1 channels whereas the ax73 just uses two of the six antenae for 2.4ghz and only one channel.

Regardless the point is moot. Even though the router has a max speed value on it's wireless connections, I never get that to an external site.

I am on a 200Mbit plan with TPG and get 250Mbit down and 20Mbit up when i do a test on a wired connection. If I do the same test on a wireless connection, regardless of wifi version or physical 802.11 standard, i only get 90Mbit down.  

So to test the advertised speeds for this router

I would have to have an ax3000 in two desktop computers or another wifi 6 adapter in a laptop or similar on the same wireless network to see what the transfer rate is.

Now that my wifes work laptop is working I can swap out the VR1600 temporarily to see if the ax73  performs better as a router as opposed to an access point.

The other thing I noticed is that the ax3000 tx50e installs and shows up in windows as a tx200 160Mhz with a windows driver that the windows 10 operating system says is newer than the ones I downloaded from tplink

More screen  prints  before my inSSIDer trial expires
