Re: [Discuss-gnuradio] USRPs having the same IP address on a network

I'm confused. How can you have an ethernet cable directly from your computer to your USRP if you don't dedicate a network card to that?

At this point, is it OK to ask you for a drawing that shows all your computers, network cards, USRPs and network cables (and other networking equipment involved, if any)?

Best regards,

Marcus

There aren't dedicated ethernet cards for each USRP. I have just connect the ethernet data cable from the computer to the USRP. 

Oh. But if I can not ping the USRP with the other computer how will I send data from one USRP to the other ? And how do I find the original factory address?

OK, so, dedicated ethernet cards on each computer for the N210s?

If so, those are, unless you turn each machine into a router that "plays nice" with the local network infrastructure, *private* connections--dont' think of them as network connections but a bus connection between your computer and the N210.  In which case, they could each have retained their original factory address.

Each USRP is connected with a different computer and therefore they both have separate Ethernet ports. There is no switch in between the computers and the USRPs.

We're going to need more of a description about how things are connected--do your USRPs have dedicated ethernet connections per computer, or are they connected to the same ports that your computers use to talk to the rest of your network?

Hi Marcus,
 
I have set the IP address of one USRPN210 to 192.168.10.3 replacing its default 192.168.10.2 IP but the I can not ping this USRP from a different computer which has the other USRP conneced to it. I can ping it from the same computer to which it is connected. Why is that? And how do you think I can fix this ?
 
Best,
Annie
