I am considering upgrading my router but I am undecided which route to go

first, I really like the Archer AX11000, I like how many Ethernet ports it has and that it has port aggregation.

My current problem is that I have a lot of TP-Link switches and amazon echos in the house so they are starting to cause issues. I have a total of 41 devices with 25 in the 2.4Ghz band and I hope to add a few more IoT switches.

My questions are:

with my expected growth, would the AX11000 be enough to handle all my devices on the 2.4 Ghz channel?

If i get the Deco X90 with two units, what's the maximum number of devices I can connect to the 2.4Ghz band?

If you think the DecoX90 is the way to go, is there a nice Ethernet switch I can pair with the main device that would do port aggregation?

thanks
