Tha’s weired. Apparently Ubuntu 8.10 kernel includes Agere driver since
my laptop perfectly works ever since I installed Ubuntu 8.10.
But when I try the “fund_usrps” while monitoring the network packet,
nothing goes out though eth0 (Agere ET131).
Unfortunately, my laptop does only has a PCMCIA slot, and
my desktop does not have GigE, either.
Well, maybe I can buy a low cost GigE card with a PCI interface for the
but the thing is that I’d like to work on my laptop…

OK, we got the driver to compile, and spent some time trying to get the
card to talk to the USRP2. If you try enough times, it sort of runs,
but with a lot of noise. It has the same behavior when running through
an ethernet switch. It turns out that the card and/or driver has some
weird sort of data corruption which puts errors in nearly every received
packet. We also got a lot of syslog messages which were warnings from
When I tried to connect the card to my router and do normal TCP/IP over
it, it can’t even get an IP address from DHCP successfully.
Basically, I think that the kernel drivers are simply not working, so
there’s no hope of getting these cards to connect to a USRP2 properly if
they can’t connect to anything else either. The fact that this driver
has not been included in the main line kernel even though the chipset
has been out for a long time (its no longer even owned by Agere – it
was bought by LSI) tells me that there are much deeper problems.
There are much better supported interfaces available. If you are using
a laptop with this chip in it, I would suggest buying an ExpressCard
(next generation of PCMCIA) GigE card with a Marvell chip in it. They
should be less than $50.
