Sep 20, 2014 8:04 AMby 1magine,Hi ,
Thanks for the reply . Only USB device connected is the Lg SuperMultiBlue drive ; HDMI out to Tv ; Thunderbolt out to 1st HD Storage .
The unit is on top of a table in the Living Room beside Lg and Bluetooth Keyboard/Trackpad .Drives are underneath along with BD Players
and HiFi kit .
When it worked , it worked beautifully but this time nothing can get it back again . Doing Hardware Test as we speak , Green across the board ,
Very Frustrating ,

Sep 20, 2014 8:18 AMby 1magine,Nope, Ram apart and that was the week it was bought in November 2012 . It was returned for a replacement to a failing HD under warranty about a year ago and that was the last time the cover was off . Im beginning to fear that I may have to wipe it and Start Over from scratch which can invariably end up losing other settings and software . This problem has gone on so long I have no faith in any of my backups unfortunately .

Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter tab, if there is one. Uncheck the box marked
Wake for Wi-Fi network access
if it's checked.
Step 5
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 6
Reset the System Management Controller.
Step 7
Step 8
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
Step 9
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Sep 20, 2014 12:57 PMby 1magine,Many Thanks for your detailed rely , I will be keeping it for future reference I haven't found Wireless Diagnostics much help as it just gave ' Cannot be joined ' messages without saying why ? I did delete any previous Airport references in the Keychain and I will disable Bluetooth in future though it will leave me without control if Screensharing should fail as it does when the Mini drops off the network .
Funnily enough , I did disconnect the only USB connected unit ( old Lg drive ) and ran the Apple Hardware Test as CS advised and after rebooting , deleting the old network and adding it again all is well ..........for now . Ive been here before but at least I will know how to troubleshoot next time .
Thanks again
M
