What do you mean "interface will go down"? Down is an administrative state,
settable only by admin (ifconfig up/down or equivalent).
If your wireless device driver does that all by itself, it is buggy.

Elaborate on "interface will go down". Provide
ifconfig, routing and iwconfig data before and
after the event.
