Hi, The N210 we had was returning ping requests after we managed to burn the latest firmware and fpga images on to it from [http://www.ettus.com/downloads/uhd\_images/UHD-images-most-recent/](http://www.ettus.com/downloads/uhd_images/UHD-images-most-recent/). At that point the green light on the ethernet port on the N210 was ON and the orange light was blinking. But now we see a solid orange light ON with no blinking and the green light is OFF. The ping requests are not being returned but the N210 stays connected to the PC. Is there anyway to reset the device? My colleague is not able to remember if he could have possibly burnt some incompatible/wrong firmware images as we have 2 N210s we’re trying to set up. Is there any way to revive our N210? These creatures entered our lab only a couple of days ago! Thanks, Siva ---

As noted in the usrp-users list: [http://lists.ettus.com/pipermail/usrp-users\_lists.ettus.com/2011-February/000686.html](http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2011-February/000686.html) We have seen a few people inadvertently suffer from this mistake. Good news is its fairly easy to get you fixed up. I will follow up with you offlist to get this corrected For others updating their N210 firmware, please make sure to use the usrp\_n2xx\_net\_burner.py from January 28th or later Thanks Jason ---

Hi, This is the first time I work with USRP N210. I can’t ping it (Destination Host Unreachable). I see a solid orange light ON with no blinking and the green light is OFF on the port. The leds D & F are ON too. I haven’t burn any firmware image yet, so I don’t know what I have to do. Can anyone help me? Regards Juan P. ---
