Bug #231

Everything worked including from my phone.

After using it for an hour or so, I started getting errors saying my net was broken. It came back briefly but now once again I cannot get a lease.

This is somewhat reproducible at least…

I plan to take the box into ISC tomorrow to see if a clean network will help.

Bug #231: Identically configured wireless does not hand out DHCP leases

Target version:


I have IPv4 and IPv6 configured for all of the sw00, se10, gw00, and gw10 interfaces. The 2.4 Ghz public interface does not hand out IPv4 addresses to any clients. The 2.4 Ghz closed network does not hand out DHCP leases to my iPhone but WILL to my Mac laptop. The 5 Ghz hands out addresses to my mac. (iPhone cannot speak 5 Ghz.)

Here is a packet capture from the 2.4 closed interface:

If you put these interfaces on the same subnet, bad things will happen.

if that is what you did?

Go ahead and close this, chalking this up to user error, for now.
