Hostnames missing on most devices

Installing and Using OpenWrt Network and Wireless Configuration

I see host name for only a few of my connected devices. Why is that? Can i get more hostnames included somehow?

root@OpenWrt:~# cat /tmp/dhcp.leases
1678502091 82:xx:21:xx:90:xx 192.168.2.106 * 01:xx:2e:xx:e9:xx:xx

Thanks in advance!

If the host devices don't advertise it in the dhcp request messages, your other option is to create static leases and add the name manually.

Thanks for the suggestion. However, before i flashed OpenWRT, most devices, e.g. iPhones, iPad, laptops etc. had hostnames visible in the Linksys stock firmware. What am i missing?

I've noticed that this can be a bit flaky. When new devices connect, they're often missing a hostname - but it can appear at a later date.

I now add a static address for every new device on my network.

You can run a tcpdump first to verify that a device is sending the hostname. Because it's visible that some devices have a hostname and others don't.
