[Discuss-gnuradio] Detecting internal GPSDO.... not found on first connection

Dear All,

my device: USRP N200
System: Ubuntu 13.04

1. I always get this on first connections (the next ones are okay):

$ uhd_usrp_probe
linux; GNU C++ version 4.7.3; Boost_105300; UHD_003.006.000-0-g7788c692

-- Opening a USRP2/N-Series device...
-- Current recv frame size: 1472 bytes
-- Current send frame size: 1472 bytes
-- Detecting internal GPSDO.... not found

2. Besides that I usually lose the connection with the port I was connected.
3. If I wait for some time, I again lose the connection on next command 
and each time I have to type : sudo ifconfig eth0 192.168.10.1.


Do you think these are normal?
