FS#3409 - can not connect to wifi after "WARNING" in klog #8267
Comments
ezar: Same here! No more wifi using archer-c7 |

bittorf:
On "TP-LINK TL-WDR4900 v1" with trunk r14723, i could
not connect to wifi anymore. I found this message in klog.
Executing 'wifi' fixed it.
I'am not 100% sure if this 'WARNING' is the root cause.
