View Full Version : Weird MAC address issue on Squeezebox Classic.

2013-10-06, 05:47

So my Squeezebox installation have been running stable in what seems forever. (LMS 7.7.2)
However, yesterday I started having issues with two of my SB Classics. The screen on one was blinking and the other one kept crashing.

I rebooted the SBs + server etc. but the issue kept coming back.
During one of the SB reboots, I noticed that it got a wrong IP, (All my SBs are registered in my DHCP server and run with a “Static DHCP assigned IP”).

I then started looking into the issue, checked my DHCP server, tried both wired and wifi – but the one SB kept getting the wrong IP.
I then tested the other SB, same issue got a wrong IP – and the same IP as the first SB!!

I then tested with wireshark, and sure enough, both SBs were giving off a wrong MAC address.
For some reason these two SBs have decided to identify them self with a wrong MAC address.
They were supposed to have 00:04:20:07:--:A8 and 00:04:20:07:--:9C but now they both uses 00:04:20:ff:--:01

I have tried a factory reset, and I have tried downloading the firmware from the server again, but the issue still exists.

Any idea on what might have caused this, and more important how do I fix this?

Thank you in advance.


PS - Both SBs work, as long as only one is connected to the network at a time.

Thank you for your reply.

Since I had already tried the different firmware version that I had lying around, I thought I could give "mysqueezebox.com" a try.
When connecting the player to mysqueezebox.com it gave me the message "Your player needs to have its mac address reset, contact support".
Goggling that error lead me to this thread: http://forums.slimdevices.com/showthread.php?94015-Your-player-needs-to-have-its-mac-address-reset
that had the answer.

So thank you :)

I've seen this happen to my SB2's after a power glitch where a byte or 2 of the MAC will flip to FF. You can set the MAC address in the firmware menu.

You should edit your post that contains Mac addresses to remove them. People can cause you problems by using those Mac addresses inappropriaely. .
