Hello,
I installed openwrt on a laptop and are ussing an Itel 6205 AGN wifi card.
The rotuer is working but sometimes the laptop/wifi reboots.
I saw this error:

I found a article to solve this:
[SOLVED] iwlwifi: Microcode SW error detected. Restarting 0x0. / Kernel & Hardware / Arch Linux Forums
But I don't knwo where to put the options.
- /etc/modprobe.b does not exist
- adding to /etc/config/wireless not used
Question:
How to resolve this issue?
How to add iwmwifi options ?
Thanks.
