Can someone please recommend a reasonably priced router I can buy and flash to build a router that supports IEEE 802.11's Time Advertisement feature?
I tried to do this with a Raspberry Pi 3+ and hostapd, but the Broadcom chip has its own ideas about what a Beacon frame should look like. It deletes the fields hostapd puts in and builds its own Beacons. I wasn't able to find documentation for the Broadcom interface, much less open source to update their firmware. So I'm hoping for a router with a wifi chip that will be more friendly to open source. (Also, I need a router with a few wired ports and antenna, so a Pi isn't ideal.)
