Data link protocol problem

Hello ALL,

I am using Ubuntu-10.04 and the latest gnuradio downloaded via git. UHD
has
been installed. However, I get ‘Destination Host Unreachable’ when ping
192.168.10.2

$ sudo ifconfig eth0 192.168.10.1
$ ping 192.168.10.2
PING 192.168.10.2 (192.168.10.2) 56(84) bytes of data.
From 192.168.10.1 icmp_seq=2 Destination Host Unreachable
From 192.168.10.1 icmp_seq=3 Destination Host Unreachable
From 192.168.10.1 icmp_seq=4 Destination Host Unreachable

I found that the data link protocol on my laptop doesn’t include Gigabit
Ethernet (Data Link Protocol IEEE 802.11n, Ethernet, IEEE 802.11b, Fast
Ethernet). So can I still use USRP-N210 on this laptop? If I can, how to
solve this issue?

Thanks in advance,
Brook

The USRP2 only supports gigabit ethernet, and will not work with a
10/100 Mbps interface. However, a 10/100 Mbps interface can be connected
indirectly to a USRP2 through a gigabit ethernet switch.

You’ll need either a 1GiGe interface on whatever computer you use, or
you could do a “translation”,
and use a 1GiGe Ethernet switch between your laptop and the N210. But
you’ll only be able to sustain
very low bandwidths using that approach–a couple of Msps at most.
