The question for me is, if I should replace the Archer C7 with an Asus RT-AX53U and the Netgear with a D-Link DAP-X1860
With the C7 I know, mesh is possible, but not so easy to setup. 2 DAP-X1860 I use already and a 3rd waits for the decision to keep or to send back. I will keep it, if configuartion is a lot easier than with the Netgear. I want to avoid to compile a kernel.
The Asus RT-AX53U has to be ordered, unfortunately no Black Friday offer
Asus TUF-AX6000 is bought and will be flashed with openwrt when the hardware is clear. The AX6000 will be "master router", makes no sense to install openwrt earlier, since work is in progress with this device.
