Usrp2 on windows - network cable unplugged

GNU Radio
1

I tried to use usrp2 on windows with the newest sd card image. Worked on
ubuntu.

But on windows, when I plug in the Ethernet cable and the power,
initially
windows shows acquiring network address, connected firewalled. After a
few
seconds, (I think it is when the image has been loaded from sd card to
the
mother board) windows shows ‘network cable unplugged’

I confirm it is a Gb network card.

What might be the cause of that?

You have to configure the network card for static IP. Same as ubuntu

You need to configure that particular network interface to use a
STATIC IP address, and NOT try to
acquire an address through DHCP. Windows is trying to find a DHCP
server on that interface, failing, and
then declaring the interface “dead” as a result.

Actually windows did show ‘connected, firewalled’. but after a few
seconds, it turned to unplugged. This is weird to me.
Well, if it really is configured for a static IP, you might see if
there’s a way to force the card to only use
1GiGe. I don’t know how to do that in windows, but I do know that
some 1GiGe PHY implementations
don’t auto-negotiate properly, so if you can force the ethernet
hardware to run always at 1GiGe, and
not auto-speed negotiate, that sometimes helps.

Yes, I did configured it as static IP 192.168.10.1

Yes, you are right. When I configure the Ethernet interface to the 1Gb
only
mode. It works!
Thanks a lot.

I have the same question now which puzzled me several days. But when I
configure the networkcard to 1Gbps, it still doesnot work. Can someone
give me some help?

Dear Kyle Z. and Marcus D. Leech,
After my configuring the 1Gb of the Ethernet card, it doesnot work. Can
you give me some help?
