Every time that a Client get connected to the internal Radio (AR2417) configured in AP mode, the RB411 board crash randomly, sometimes in 5 secs, somtimes after a couple of minutes.
I've tried w/o sucess:
- 2 boards.
- Backfire's images, but also, tried with Trunk.
- Initramfs and Nand.
To duplicate the problem:
- Image used: openwrt-ar71xx-vmlinux-initramfs.elf created from trunk with default openwrt config. Or use NAND image from http://downloads.openwrt.org/backfire/
- #vi /etc/config/network, comment the like that disable the radio
- #/etc/init.d/network restart
- Connect a client to OpenWrt AP.
- If you are lucky and the board didn't crash yet. Open a browser to 192.168.1.1
Results are kind of unexpected (Looks like memory corruption), Sometimes
it reset itself and other I got this:
