Sounds a bit like this: https://bugzilla.kernel.org/show_bug.cgi?id=195299 So if it is that it should be fixed in 4.14 kernel. Not sure what current mint uses. A search seems to indicate it may be 4.10. It sounds like the trigger is a router using an illegal channel width on some channels on 5GHz. At least that was what one person found. -- Len Sorensen --- Talk Mailing List [email protected] https://gtalug.org/mailman/listinfo/talk
