Very similar to problem report 32536

Using wpa supplicant, the connection drops when I download something, i.e. pkg_add some package remotely with PKG_PATH pointing to my nearest mirror in my country.  It seems to happens when ever there is high traffic as mentionned in the other problem report.  I do not do any ssl tunnel and I get the same trouble.

I use the wpi driver.  If you want I will try with some atheros card eventually to see if it also happens with it.  I don't know if it is related to the driver, wpa_supplicant or something else. Nothing appears in the logs, just no network when it's heavily sollicitated.

I tried wpa supplicant on FreeBSD 10.1 release and there is no issue with it, it holds the load just fine. Too bad I would like to use NetBSD on that laptop. Thank you.


called with:
wpa_supplicant -B -i wpi0 -c /etc/wpa_supplicant.conf
dhclient wpi0

The AP provides WPA/WPA2 AES-TKIP.
