I'm having issues with the Wifi when the computer wakes from sleep. For some reason it can't find my network, or any other network - it just searches for networks without success. The only thing that works is to turn wifi off and then on again. Can't find anything in the wifi log files, or any other log files. Really annoying problem...
If not using an Apple Airport router, it may need a firmware update. Otherwise you may need to clean up the preferred networks in the Network System Preferences customization.
I have:
- cleaned up the preferred networks. Removed all of them.
- removed the Wifi configuration/service in Network preferences and added a new.
- performed a PRAM reset
- updated the router firmware. But I'm acually having this problem with several networks...
None of this has worked.
