hello,
i am using a 1043nd-router as access point (operating system: OpenWrt Barrier Breaker 14.07 / LUCI)
For a short time if i enable wlan on my mobile phone or tablet pc (android-, windows-os), the ip adress will not be allocated (message on mobile phone: "try to allocate ip-adress ..."
If i assign a fixed ip-adress for each mac-adress, it does work (luci -> DHCP and DNS -> Static Leases).
why the router is not able any more, do assign a random ip-adress automatically?

We will need some more info to be able to help with this.  Please check your system logs for errors when you experience a dhcp failure.

is dnsmasq running?  not a single message from it in the log you posted.

Barrier Breaker is very old, please consider upgrading.

The discussion might have continued from here.
