I recommend buying a miniPC that has at least 2 network ports and install OpenWRT on there. You can do it on ARM-based PCs or even x86_64 based PCs.
Then connect this miniPC to a cheap 8-port switch, and get some WiFi APs and connect those also to the switch.
This way you will get a much more powerful and reliable "router" that can't ever "brick". Better WiFi quality with good Prosumer / small business APs, and the ability to upgrade your WiFi independently of your router as needed.
Something like this for example:
