Can't figure this out. It's almost like the firewalla can't grab the ISP's address via DHCP but two laptops I have on me will.  Purple shows blinking red status light.

Not sure what to try

EDIT: I run network diagnostics and the "Ethernet Port (WAN)" says "connected" but "Obtain IP address" fails

  I have created a case for you, and will need to grab some logs

  I have retrieved the Purple from the other location. I've added it to my network here (home) and it does the same thing. It blinks red.

  I can get the Diagnostics to run and I get this:

  

  Just to be complete: this Purple is on my home network which is manage by a FWG.  The cable used is the same cable that works fine with a laptop.

  OK, five minutes later, I ran the Diagnostics again and it got one step further.

  

   

  EDIT: I waited 10 minutes and the Diagnostics worked all the way through, then tried it again and it failed at Ping Test.

  You have a case open on this already, best just reply to our support directly, it is going to be a bit faster than posting

  Bit of a late reply but does your ISP use MAC address locking?  This is an annoying thing that some (like mine) do, they lock access to a specific MAC address or small pool of MAC addresses and so won't respond to traffic from anything else.

  Did you ever get this solved. I am experiencing the same issue.

  The resolution was that I worked with support and my box had a bad ethernet port. It was under warranty at the time and they swapped it out.

  That was 2 years ago and the replacement Purple has been rock solid ever since.

  I believe they isolated it to a batch of serial nimbers, but not 100% sure.
