This is one of the reasons I've separated the router from the AP on my network. I'm running OpenWRT on a normal computer as the router because I'm familiar with setting it up and then using some TP-Link Omada EAP devices for the Wifi part of things. I don't like that they're completely closed as far as firmware/software goes but I'll live with that compromise because it gives me the ability to manage the wifi separately, and then the APs also support VLAN and some other features that lets me handle things nicer than I could with consumer grade routers (with or without stock firmware).
