Hardware: Qualcomm IPQ8072
Software: 15.05
Issue description: DHCP client hostname was shown as ? in luci, in tmp/dhcp.lease, it was shown as *
Additional info: Wireshark capture shows client hostname was successfully transmitted to AP during DHCP exchange. Updated dnsmasq from 2.79 to 2.80, issue remained.
I understand static lease might solve the problem, however, the device will be deployed in non-fixed-clients environment and this feature is required to identify clients easily.
Any inputs are welcome!
