I recently had my USRP N310 sent out for repairs to fix one of the SMA
connectors, and when it came back, there was a new SD card in the slot.
When I turned it on after getting it back, I was unable to connect to it
via 'uhd_find_devices'. I figured it was something with the SD card, so I
eventually decided to rewrite the whole thing, in case it needed an update.
That still did not fix the issue, and after trying just about everything,
and following every possible tutorial on the ettus docs, and checking the
forums, I have decided to ask you guys for help.
Below you can find all the information about the UHD versions and the
ifconfigs... hopefully that is enough to spark some ideas!
The USRP can find itself on localhost as you can see here:
*root@ni-n3xx-3177E63:~# uhd_find_devices[INFO] [UHD] linux; GNU C++
version 7.3.0; Boost_106600;
UHD_3.14.0.0-0-g6875d061----------------------------------------------------
UHD Device 0--------------------------------------------------Device
Address: serial: 3177E63 claimed: False mgmt_addr: 127.0.0.1
product: n310 type: n3xx*
But when I run the command from the host machine, this is what I get:
*admin@PC:~$ uhd_find_devices[INFO] [UHD] linux; GNU C++ version 8.3.0;
Boost_106700; UHD_3.14.0.HEAD-0-g6875d061No UHD Devices Found*
*Here is ifconfig from the USRP:*

*And here is ifconfig from the host machine:*

I tried broadcast pinging 192.168.10.255 and 192.168.10.2 from the host
but didn't get a response from the N310 or anything for that matter.
I hope someone out there can help me out! Thank you in advance :)
Best,
Austin
