UHD version is 3.008.004.
Looking at the connection properties in the Windows Network/Sharing
Center, I see "Realtek PCIe GBE Family Controller" listed as the
ethernet controller. Looking at the network settings through the VM, the
adapter type "Intel PRO/1000 MT Desktop (82540EM) is listed.
Thank you for crossposting and your continued assistance.

What version of UHD are you using?
Any idea what ethernet controller is used on that dual-port card?
You'd have to go into windows configuration to determine this, since I
think that 'lspci' on the VM side will see some kind of emulated
network card.
I've taken the liberty of copying this to the usrp-users list, since
this is more USRP-centric, than GnuRadio-centric.

I am indeed running inside a VM presently. Details below:
Hardware:
USRP N210 (2x) connected to dual-port gigabit ethernet card:
http://www.newegg.com/Product/Product.aspx?Item=N82E16833166096
Software:
Windows 7 host OS
VirtualBox VM running Mint Linux 17.1 (Mate Desktop edition)
Network settings:
+ Adapter enabled and attached to NAT
+ No port forwarding settings defined
It may be noteworthy that the receive operation of the USRPs works as
expected. Only transmit doesn't appear to be working properly.
Thanks,
George

This is usually due to your network subsystem re-ordering packets,
which is never supposed to happen but certain
1GiGe interfaces, particularly USB ones, do this quite a bit.
Are you running inside a VM?
What kind of network interface do you have?

Hello,
I'm working on developing some gnuradio exercises, some of which
involve using USRP N210 devices as transmitters. When I attempt to run the
related flowgraphs, I get a stream of sequence errors (S) in the GRC log
window. Attached are a pair of GRC flowgraphs in which I am getting this error.
I have tried installing the latest images to the USRPs and updating to the
latest version of gnuradio available on the github master branch. Can somebody
please point me to what I'm doing wrong? I've searched around on the topic for
quite awhile, to no avail.
Thanks,
George
