Our latest build under openwrt backfire, we see dhcp requests failing to get a response. We see the this on UBNT routerstations and UBNT Picos. <div><br></div><div>An open ticket with openwrt exists at <a href="https://dev.openwrt.org/ticket/7917">https://dev.openwrt.org/ticket/7917</a> as well</div><div><br></div><div>Were ready and willing to dive in to help identify where to look to at least determine if this is a wpa_supplicant issue, kernel issue, or something in between, but are not sure where to start. Any help would be appreciated.</div><div><br>Setting a static IP to the bridge yields success and traffic flows fine. We have tried udhcpc and dhcpcd and both time out.<br><br>Connecting to a hostapd AP we can see the dhcp requests on its ingress i/f, and see its response, but on the station side we only see the request leave.<br><br>Other stations (our macs) connect to the APs fine.<br><br>Is there any known issues or any ideas on how to resolve?<br><br>Thanks in advance... Were stumped...<br><br><br>.conf file<br><br>ctrl_interface=/var/run/wpa_supplicant<br><span class="Apple-tab-span" style="white-space:pre"> </span><span class="Apple-tab-span"
