Hi Daniele,
all of what you describe is intended behavior.
First off, UHD tells you *exactly* what to do. Run:
`sudo sysctl -w net.core.wmem_max=24862

Hi Daniele,
all of what you describe is intended behavior.
First off, UHD tells you *exactly* what to do. Run:
`sudo sysctl -w net.core.wmem_max=24862979`
Nothing else. Just copy the previous line without the ``.
The same goes for the rmem part.
These changes are valid as long as your machine run
The number that seems configured every time I run uhd_usrp_probe is
1048576 that is the value present in the file wmem_max in the directory
/proc/sys/net/core/
I searched also the way to modify this value and I found:
sudo -s -H
echo 24862979 > /proc/sys/net/core/wmem_max
If now I test the number

# /etc/sysctl.conf - Configuration file for setting system variables
# See /etc/sysctl.d/ for additional system variables.
# See sysctl.conf (5) for information.

#kernel.domainname = example.com
# Uncomment the following to stop low-level messages on console
#kernel.printk = 3 4 1 3
