I would suggest for you to connect both routers via ethernet and use the secondary router as access point. If your secondary router have dedicated AP mode, just use it in that mode, otherwise just manually set it as access point. This way, you don't need to care about multiple subnet and/or double NAT issues.

To check local wifi speed, I normally use iperf3. It require 2 device, 1 act as server and another 1 act as client. It is recommended that the server is directly connected using lan cable (cat 5e or higher) to the router/switch (and make sure it is gigabit capable). Then the client can perform the test using either wifi or lan cable.

Ax20 is gigabit capable over lan. Could be your lan cable or your pc mootherboard ethernet port that could only support up to 100Mbps

I think your expectation for the default firmware/software is too high for a consumer level grade router. Btw, may I know is there a router in the market right now that fit your needs with its default firmware and not 3rd party?

For the coverage, I may disagree with your opinion since I'm owner of ax73 and it perform better compared to the slighly pricier but lower specs asus rtax56u.

I personally own rt-ax56u and ax73 before this, out of the box performance ax73 is far superior in terms of peak speed, speed consistancy and a little better on the coverage. End up selling the rt-ax56u and kept the ax73 until now. At that time, both of them are similarly price.


It's the same thing happening on asus line up too, cheaper model like rt-ax55/rt-ax56u is using quad-core chip but the more expensive model is using tri-core chip like rt-ax3000/rt-ax3000-tuf/rt-ax82u.

Not sure the exact reason behind it, but the pattern I notice is asus's quad-core model is using the built-in chip for both 2.4 and 5ghz, but the tri-core model is using dedicated chip for their 5ghz.

Yes, blacktubi was right mr70x is using mediatek, can refer to this article but it's in russian
