After I upgraded to 10.7.4, the usb ethernet stopped working. When I plugin the usb ethernet port, it still shows "Cable Unplugged". Any suggestions? Thanks.
MacBook Air, Mac OS X (10.7.4), Mid 2011 model
Try running software updates with the adapter plugged in
I tried but it said my software was up-to-date.
When I click on "About this Mac" --> "System Report" ---> "USB", there is no "usb ethernet" adapeter
in there.
It worked fine before, only stopped working after I upgraded to 10.7.4.
Try resetting your SMC http://support.apple.com/kb/HT3964 and your PRAM http://support.apple.com/kb/HT1379 Let me know if that works/helps 🙂
It turned out that the problem was my usb ethernet port. I borrowed another usb ethernet port and it worked
fine.
The strange thing is that this thing stopped working after I upgraded to 10.7.4. It was only a little more
than a year old.
FIxed my problem!
After years the problem was solved somply!
Go to System preferences
Go to Ethernet
Go to Advance
Go to Hardware
The just make the changes like in the pictures below
USB ethernet stopped working on 10.7.4.
