In win10 evrithing is OK with atheros card but in FreeBSD i have strange
problem. ping works but if i try to load for example www.speedtest.net it
stops loading page...temporary fix is that i have to change mtu. For
exapmle if i change mtu from 1500 to 1400 (or any other value) card start
to work and page loads ok .. if i change mtu back to 1500 evrithing works
Ok for some time and it hangs (ping works but it stops loading some
pages).. So how can i trace what cause that problem??
tnx
