USRP N210 - Calibration Utilities failing due to underrun

Hello,

 

I am having trouble in configuring an USRP N210:

OS Windows 11

UHD 4.6.0.0 release, Win32

FW version 12.4

FPGA version 11.1

 

First, I tried the benchmark rate script where I get underrun already at 1Msps (generally one) to 10Msps (around 700).

On top of that, at the end of the script I get some caught exception indicating "ValueError: bad art header or packet fragment".

 

Then when I try the calibration commands I get some underrun with a "TX error detected!" message. 

 

I already changed the "FastSendDatagramThreshold" to 2048 and I am with a 2.5Gbps LAN port on my computer.

 

Do you know what can be wrong?

 

Thank you!
