If you are one of the MacBook Air owners who’s official Apple USB Adapter is giving you a few problems, there may be a fix that can help you work around the problem.
A post on the Apple support forums has been gaining length as users report problems with the USB Ethernet adapter. With some users reporting that it does work but only in the right-hand side USB port while others say it doesn’t work in either.
Understanding the Issue
However, the problem is not the USB Ethernet adapter itself, since all seem to work on other Mac systems. This suggests that the issue is specific to the MacBook Air’s hardware or software configuration. Users have speculated that it could be related to the power distribution to the USB ports or a software glitch that affects the recognition of the adapter.
One user mentioned that the adapter works intermittently, which could indicate a loose connection or a problem with the USB port itself. Another user pointed out that the adapter works flawlessly on their older MacBook Pro, further supporting the theory that the issue is isolated to the MacBook Air.
Potential Workarounds
A simple workaround might solve the issue for you. If you create a new location in Network Preferences and then try connecting the USB Ethernet adapter again, this does seem to solve the problem for many users. To do this, follow these steps:
- Open System Preferences and go to Network.
- Click on the drop-down menu next to “Location” and select “Edit Locations.”
- Click the “+” button to add a new location and give it a name.
- Click “Done” and then “Apply.”
- Reconnect your USB Ethernet adapter and check if it is recognized.
This workaround essentially resets the network settings, which can help in re-establishing the connection between the MacBook Air and the USB Ethernet adapter. Some users have also found success by resetting the SMC (System Management Controller) and PRAM (Parameter RAM), which can resolve various hardware and software issues.
To reset the SMC, shut down your MacBook Air, then press and hold the Shift, Control, Option keys on the left side and the power button simultaneously for 10 seconds. Release all keys and then press the power button to turn on your MacBook Air. To reset the PRAM, restart your MacBook Air and immediately press and hold the Option, Command, P, and R keys for about 20 seconds.
Being such a small problem, it shouldn’t take long for Apple to issue an official fix. In the meantime, these workarounds should help you get your USB Ethernet adapter working again. If the problem persists, it may be worth contacting Apple Support for further assistance.
Additionally, some users have reported that using a powered USB hub can help in resolving the issue. This could be because the powered hub provides a more stable power supply to the USB Ethernet adapter, ensuring it functions correctly.
It’s also worth checking for any available software updates for your MacBook Air. Apple frequently releases updates that address various hardware and software issues, and an update might include a fix for this specific problem.
In conclusion, while the issue with the USB Ethernet adapter on the MacBook Air can be frustrating, there are several potential solutions you can try. Creating a new network location, resetting the SMC and PRAM, using a powered USB hub, and checking for software updates are all viable options. Hopefully, Apple will release an official fix soon to permanently resolve this issue.
