Hi Everyone! I've been getting a few APs set up after flashing to OpenWRT, but I noticed that the menus when adding a static lease under Network -> DHCP and DNS -> Static Leases seem to have a bunch of old addresses from when I was getting the AP initially set up. Is there a way to clean up the ent…

In theory, a reboot should clear those (assuming they're not connected to the network anymore and that there are no static leases currently defined with those MACs).

Well, that's not really what I was going for. See the screenshot below. I've got a bunch of old/stale IP/MAC combos in those lists and I can't figure out where they're coming from. The device isn't attached to the 172.17.1.x subnet anymore, but they're still in the list [image]

Use SSH to connect router: rm /tmp/dhcp.leases /etc/init.d/dnsmasq restart Delete entire lease file. This will clear all current DHCP leases and will request new leases as needed.

Apologies, those entries only show up in the static lease modal in the IP address and MAC address options.

Not sure why it worked that time, I could've sworn that I had rebooted it several times trying to get rid of 'em, but this time it finally worked. Thanks for the assist!

(The non-standard button you seek doesn't exist in OpenWrt.)

You can also lower the lease time.
