All, When I connect my USRP N200 to a PC running Suse, run ifconfig eth0 192.168.10.1 command, and then run command uhd_usrp_probe --args="addr=192.168.10.2", I see the famous error message: LookupError: KeyError: No devices found for -----> Empty Device Address The weird fact is that I have 9 other USRP N200 radios which get detected when I run the command uhd_usrp_probe --args="addr=192.168.10.2" on the same PC (so it shouldn't be a firewall issue). For the problematic USRP N200 I have done the following: ping 192.168.10.1 which is fine ping 192.168.10.2 which shows the error message that destination is unreachable I have also used switch S2 to enter into safe mode, burn the right binaries (3.4.4 from maint branch), power-cycle the device but the problem persists. Any ideas on what might be preventing the USRP N200 from being identified by the host PC? Thanks in anticipation, Mahboob

Hi Marcus, I assume you are talking about the green LED on the top left of Ethernet port on USRP N200. If so, then it remains On. However, I don't see any yellow activity light at all. Furthermore, only LED D and F are On. Thanks, Mahboob ________________________________ From: firstname.lastname@example.org [email@example.com] on behalf of Marcus D.

Hi Marcus, Thanks for the helpful suggestion. The USRP is indeed using an IP address of 192.168.10.3. Sure, I will restore the defult address by running usrp2_recovery.py later.

I suspect that your device had its IP address changed.
