Re: ubuntu access point freezes on conne

> same result

Before a while (half a year), I have complained here that
madwifi-ng freezes in AP mode. There was no interest to fix it.
I did not face kernel freeze, but only WiFi AP become inoperable.

Fortunatelly madwifi-0.9.4 works in AP mode for a long time.

I faced the same problem while I was sending packet from UDP layer at 60Mbps ... probably ATH hardware queue cannot handle this rate for long time.
