Priority: normal Milestone: Barrier Breaker 14.07
Component: base system Version: Trunk

Description

Tested on wr741nd v4.3 r30919. When the router boots up, it does not search for IBSS networks, but just creates a new one, although it is existent. After wifi command is called, it finds the existing one, if called again or any number of times it does not find it again.

wireless config as reported in #11209
dmesg output, at 51 called wifi command
