From what Dan posted it said the bug happens when the DNS server
doesn't respond. Are you finding something different?

No, we do our own DNS (always have). But, even though the DNS is
accessible and working perfectly, the SM craps out (no local
Ethernet data works) when we put our DNS numbers in the SM. Take
them out and the SM works fine. The RF interface works fine
either way.
I was just stating that Cambiums comment about “and the DNS server
does not respond to the device” would seem to imply that you have
an invalid DNS server. And, I am saying that is not the case.

Hmm. Looks like Paul isn't doing his own DNS server ;)

Hi,
We have determined the defect.
The problem occurs when there is a valid DNS server on the
device and the DNS server does not respond to the device. To
avoid the problem until we come out with a fix, either make
sure the DNS server always responds or make sure no IP address
is specified for the DNS server either statically or from DHCP.
We are working on a fix now and will post this as soon as it
is ready.
If the problem occurs, the device will become accessible, but
it will take about 15 minutes.
Dan

This ONLY applies if you add DNS to the device.

Guys,
Just be aware there is a known issue with 2.6.2 that can cause
the radio to not respond on the Ethernet side. It’s a known
issue on Cambium’s site. It bit is in the butt a couple times
this week. We have found that its best to NOT but DNS in AT
ALL to be safe, as their description of the problem and
“solution” doesn’t necessarily match our experience. We had
working DNS values in several radios and they wouldn’t respond
until we removed them.

Has anyone seen DFS false positive issues in 2.5.2? Newer
firmwares pretty safe?
