I just got my Obi in today, and I plugged it into my network. Everything went well during the configuration, and I was pleasantly surprised at how simple everything worked. I noticed that the firmware update button was enabled on the obi webpage, so I went ahead and updated the firmware through it. It claimed that it upgraded successfully, but once it did I noticed my internet connection totally died.
I thought this was a coincidence, so I did the standard router check (a Tomato'd Linksys e2000) and even rebooted it to no avail. I noticed the WAN was disconnected and would never connect. I checked the logs to no avail. On a hunch, I unplugged the Obi and boom, the router got a WAN IP and everything began working. I then plugged back in the Obi and few seconds later the WAN disconnected all over again. Unplugging the Obi fixed everything again. I even did a factory default reset on the Obi and it did nothing to help. For reference I have Verizon FIOS and log in via a PPPOE connection.
For some reason, it looks like the firmware upgrade may have screwed my brand new Obi up. I'm not sure how it's doing what it's doing. There is no IP conflict or anything obvious like that. Has anyone seen anything like this before? I'd hate to return it for something I could fix here.
