We think could be some situation which the wi driver can't answer > correctly. Removing and reinserting card may have power cycle on the card, but not the system. So the driver may not reinitialize the card if there is a recovering status set. You had better case than I have. If card is removed from my system, the whole system will be frozen. > In our routers there ins't other OS and it is very difficult to test > because this happen after some hours working fine.

From the information you provided, I think it is caused by losing the connectivity, and there are some bugs inside driver to cause wireless system die. My experience is that the wi0 may die anytime just from boot-up to after worked a few hours. I know it is caused by losing the connectivity, but do not know if this is caused by traffic or weak signal. To me, it seems a driver bug. Since I did not use wireless so often, I cannot file a bug report because I do not have time to play with wi0. If you have a dedicated use use with wi0, then you should file a bug report once you can repoduce such problem by introducing some heavy traffic (not hard at all for creating 11 Mbps network traffic from any host). > > MS Windows does not try to look such status, and just re-initializes the card. > > So, > > if BSD cannot recover the wi0, boot to window, then boot back to BSD, and wi0 > > will work again.
