That is quite a bummer.
The BCM4331 is only supported by b43 not wl. If the BCM4718A1 has the same wifi core as the BCM4718 it will work with b43, brcmsmac or wl. Yes support for newer Broadcom based wifi chips is very poor. > That has me questioning is there any OpenWrt roadmap on supporting the > broadcom based 5 Ghz chips? I am currently working on getting AP mode in brcmsmac working in 5GHz mode but this is just for devices supported by brcmsmac. The problem is that Broadcom does not support OpenWrt in any way and we are not even allowed to update broadcom-wl to a more recent version, because the contract some has with Broadcom does not allow him to do this > Also, the new hardware (based on BCM4706) will support Ethernet (due to > bgmac) but the WiFi is still a question mark.

No one I know of is working on the Broadcom ac-phy, your best changes are that we somehow get a more recent broadcom-wl version or Broadcom adds support for this phy to brcmsmac. If you want a router with good OpenWrt support choose one Atheros based device. > PS. My CP2102 USB to UART is blown and I'm waiting to receive another one. > Do I just connect the TX, RX and GND?
