The problem is possibly with the lan card.
Is the lan card of your computer intel 82577 or intel 82579?
When I used computers with these two types of lan cards, I always saw
Later when we buy new computers, we avoid these two types of lan cards and
we never see the problem again.

Subject: [USRP-users] about overflow on laptop
Now I met a very strange overflow problem with my new laptop. My code works
fine on my old desktop but now I have got a new laptop. I always get
overflow when I connect to usrp N210. Even if I just test the benchmark with
very low bitrate (250khz, gmsk), I still met overflow.
I am quite sure it should not be because of the performance of CPU, because
the use of CPU is just around 50% (CPU is i7-3520M 2.9ghz*4). I have tried a
lot but still can not find out where is the problem.
The uhd I used is 003.005.000
Anyone has met the same problem? Any suggestions would be appreciate.
