Seriously, that should be a single google search, I can’t find it. It’s  
not  
in the documentation. What the hell. This is the trouble I’ve had with  
quite a few things on GNU radio, no startup info is available.

There’s this:

> **[USRP Hardware Driver and Device Manual: Device Manuals](https://files.ettus.com/manual/page_devices.html)**

And the generic information about “device naming”:

> **[USRP Hardware Driver and Device Manual: Device Identification](https://files.ettus.com/manual/page_identification.html)**

And there’s information about re-programming the IP address of your  
devices:

> **[Change the USRP2's IP address - USRP Hardware Driver and Device Manual: USRP2...](https://files.ettus.com/manual/page_usrp2.html#usrp2_network_changeip)**

The UHD manual isn’t particularly well-hidden.

Jon,

Did you try typing “change usrp ip address” into a google search? The  
first hit is [USRP Hardware Driver and USRP Manual: USRP2 and N2x0 Series](http://files.ettus.com/manual/page_usrp2.html), which does  
have  
the information you are looking for.

Since the USRP isn’t specifically GNURadio, it’s generic SDR hardware,  
GNURadio does not have this information; the place you needed to look  
was  
at Ettus R. for the documentation on the USRP.

Hope this helps,

Michael B.
