Usb ethernet problems

I've gone through several USB Ethernet dongles today. One was a generic product that worked for less than a minute and forced me to shut down my macbook air, the second was a Belkin that never worked and the 3rd was an actual new Apple USB/Ethernet dongle. The last two never worked at all. Is there some special procedure to get these adapters to work?

You can try to download the latest ASIX AX88772B/AX88772A/AX88760/AX88772 Mac OSX 10.7 driver v3.5.0 from ASIX's driver download web page (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=97) and refer to the driver installation guide to update the revised driver onto your Lion Mac OSX 10.7 system.
For the AX88178 USB 2.o to Gigabit dongle, please refer to AX88178 Driver Download web page (http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=84) to download the latest AX88178 Mac OSX 10.7 driver v3.6.0 and also refer to the driver installation guide to update the revised driver onto your Lion Mac OSX 10.7 system.

Another USB Ethernet problem

I've read all the post regarding this issue. All of a sudden my wired internet connection can not be established. The USB port and ethernet adapter work fine (I checked them). I try to set up a new connection and it 1st says No Ip address and the light is yellow, but then I get that there is not ethernet plugged into my computer. Frustrating. The air is not reading my ethernet. Any help?Thanks.

I am tempted to do a full OS reinstall as this has helped some people. The reinstall option has been the only one that Apple has provided. I would rather they (apple) not get in the habit of using "reinstall" as an option for their own QA shortcomings.
What if anything have you done to insure that the system installed on your Mac was free of any defects before you applied the update? By far the most common reason reinstalling the OS fixes update problems is that some part of the system was compromised after the OS was originally installed. Unlike installing the OS, which runs under the control of an external copy of the OS, an update runs under the control of the very copy of the OS that is being modified. Thus, a corrupted system file, a third party modification, or any of a number of other problems that can go undetected in normal use can interfere with the proper application of an update in ways that are very hard to differentiate from a problem in the update itself.
IOW, it is Apple's responsibility to provide products free of QA shortcomings, but the user's responsibility to make sure those products do not become damaged or adulterated after they are delivered. Apple provides some tools (like Disk Utility) that can detect & repair some damage but it isn't practical for it to provide tools that can detect or repair every possible problem. For these, reinstalling the OS is a more practical & often much quicker solution.

USB ethernet does not work in left USB port

My USB ethernet adapter does not work in the left USB port on my MacBook Air, but it works in the right side. Other devices, like my mouse, work fine in both ports.
Could I have a faulty left-side port with too little power for the ethernet adapter, or is this normal for MacBook Air?

I have the same problem.
USB Ethernet doesn't work with the left USB port. It does work with the right USB port, and any other USB device works with the left USB port on my macbook air
Any solution to this problem?

USB Ethernet no longer recognized?

Hi
After a reinstall of Leopard to remove languages and the sorts I had a slim installation on my air and everything was running nicely. Now however the USB Ethernet is not being recognized at all .. I have checked with the superdrive and no problems there. I have plugged the USB Ethernet dongle into my MBP and the dongle is clearly alive.
Why will my MBA not recognize the thing anymore? It just sits there utterly unresponsively, claiming that the cable is unplugged .. which it is not??
/Jan

Hmm .. one extra restart seemed to take care of business. How odd. Anyways everything is working here for me again

USB ethernet connection via switch no longer works after installing Mountain Lion

Since installing Mountain Lion, I have no longer been able to use my USB ethernet connection via an ethernet switch. I have deleted and re-added the connection in preferences. The connection reads "Connected" but it is not working as connected (unless I bypass the switch and plug directly). I have tried doing this with two different switches to no avail. Does anyone have a solution? Thanks.

I Read this sollution elsewhere on these forums and found that this worked for me.
However, the "load" time in Safari is not as fast as it used to be. Might be due to some router setting.
Solution:
For all the Dutch users that have a KPN Experiabox router:
1) go to http://192.168.2.254
2) Username: KPN Password: leave empty (You might have changed this yourself)
3) Go to Network (at the top)
4) Go to WLAN (at the left)
5) Set as follows:
Enable WLAN: Enable
Mode: IEEE 802.11g Only
Channel: 7
Transmitting power: 100%
Enable WMM QoS: Disable
This fixed my wifi problems. Good luck

Printing to the network via USB Ethernet

I have a pair of MacBook Air's that are using the USB Ethernet adapter to connect to the local ethernet (wireless is not an option, all workstations must be wired while in-house.)
The problem I run into is that both of these MBA's will loose their connectivity to the printers, or their ability to see bonjour devices at all, or Appletalk devices. In particular, I've installed a set of OkiData printers on the network which support both Bonjour & Appletalk. When I setup the printers as IP printers, they seem to work fine. However, if they, or any other printer, is connected as a Bonjour device, eventually the MBA stops recognizing/seeing/looking up Bonjour items on the network.
Any thoughts on why this is or how to correct it would be really useful, especially since some day the users might like to do some bonjour-based file sharing.
Thanks!

I have a client with the exact same problem. No bonjour when attached via USB ethernet (Apple's own) SOMETIMES. However, I've noticed that if she unplugs and tries the other usb slot, it seems to work (immediately, no reboot). I've actually only told her to do this over the phone, but it has worked at least twice.
One problem here is that the printers are NOT accessible via bonjour over WLAN, since the WLAN is at least 2 different C class networks.
The other is that due to the setup of the printers and crap drivers from Ricoh, using personalized printer queues only works over Bonjour and not TCP. Thus, only USB ethernet can be used for printing. It would be very interesting to hear if changing usb ports might help in your case as well. This particular client has a late 2010 MBA 4G/128G, but at the same department there are at least 7 MBAs where no-one has had the same problem. Either that, or they had it but never told me.

Cannot apply OS image to lenovo with usb Ethernet

Greetings,
We have a Windows 8.1 task sequence which works fine on over a dozen laptops that have an ethernet adapter. We recently acquired a Lenovo Helix machine that doesnt have an inbuilt adapter but has a usb ethernet adapter. I found the driver for this
and added it to our winpe image (we are using sccm 2012 r2, adk 8.1, winpe 5). When I use the same task sequence, it always fails on the apply OS image step. Relevant log entries here:

Does OSD have a problem with USB ethernet adapters? It appears so....
Thanks
David Z

Yes, it does have something to do with USB Ethernet. Before conclusion, we may check if there is a workaround or fix for this issue to make OSD work. So, please check the IP Info when the issue happens.
Another way is to use a Standalone media.

USB Ethernet no longer shows in System - USB or on network list

Hey,
I've been using a USB Ethernet to connect my Macbook Air to the internet for around a month. A couple of days ago it stopped working, showing 'Not Connected' in the network list. I followed the standard advice of swapping out locations, didn't work becuase I couldn't add the USB Ethernet to the list. I then took the advice of removing the Automatic location, and now the only network that is listed is wifi... Nothing gets added to the list, when I try to tether over USB with my phone it doesn't get added correctly to the network list either.
I've reset my SMC and PRAM too.
In System -> USB it doesn't seem to be listed either, although it does detect something, it doesn't seem to be able to realize it is my USB ethernet.
ifconfig -a shows the following;

Apple USB Ethernet Adapter after reboot

Hello everyone,
We have a group of 3 or 4 MBAs that are showing this same issue. Whenever we reboot we need to unplug and then replug in the ethernet adapter in order for it to connect to the network. This same problem is seen regardless of the adapter being plugged directly into the computer or through a USB hub.
It also happens when we "undock" and then dock back in from the USB hub.
Has anyone else see this issue? Have you found a solution?

Yes, Yes and NO!
What's worse is sometimes you get full 100Meg/Full Duplex and even Bonjour services, then for no reason it connects at 10base half duplex and NO BONJOUR.
I'm convinced it's the USB-Ethernet adaptor, as I get the same problem using it with a MacBook Pro, at first it works great, then you restart and it looses Bonjour and sometimes you can see all the Bonjour enabled devices drop off the Shared list in the Finder.
I've had this problem ever since I started using the MB AIr (Late 2010) model.
I don't think Apple are bothered about fixing the problem, as they seem to assume all MB Air users are on Wireless (which also has it's problems)
It remains to be seen if Lion fixes it or they just give up and go to ThunderBolt on the next generation MB Airs with a suitable Gigabit adaptor.

Apple USB Ethernet Adapter and VLAN??

Bought the Apple USB Ethernet Adapter today because my built in ethernetport on my MBP stopped working. What I know I need to replace the motherboard to have it fixed, so I thought the USB adapter could be useful until then.
But, it didn't work! I only got a "Self assigned ip-address". No matter what I do. I also entered an ip-address manually with no success.
Later at home I tested again, and Voila!! It worked perfectly!
Back at the office, same problem... I only get a "Self assigned ip-address"...
My conclusion of this is that the Apple USB Ethernet Adapter doesn't support VLAN?? Could anyone confirm that or better of, suggest a solution??
Would appreciate it a lot!
PS. Yes we do have Wi-Fi, but it's restricted and is not a solution for me. DS.

Create a new network location and try again.

Ethernet Problem

Hi.
I have a 800 Mhz iMac flat panel that has had a ethernet port issues for a few years, but I have been using the Airport with no problem. I now have faster Internet and would like to connect it via Ethernet, but have not been able to do so.
I ran the network diagnostics and it did not work. I have attempted to reset the PRAM and NVRAM to no avail. Are there any other options I am forgetting? Do I simply have a broken port? How fast is a USB/Ethernet adapter? Is it quicker than the first generation airport?
Thanks for your time.

Hello,
Very few home Internet connections are faster than even the oldest Airport cards. The original Airport card is 11Mbps, USB1.1 is 12Mbps, Ethernet (in these iMacs) is 100Mbps. Most ISPs in the UK only offer "Up to 8Mbps" and this will be shared between your iMac and MB.

USB Ethernet will not configure

Hello,
Today I started to have problems with my USB Ethernet dongle on my Yosemite Macbook Pro Late 2013 Retina. I deleted the device from Network Utility then rebooted thinking I would re-initialze it. After rebooting, the System Info recognizes the USB LAN device but Network Utility does not list it. This appears to be software issue. I have confirmed the dongle works fine on another laptop (Windows). Any ideas how to fix this issue?
TIA

The driver is built into Mac OS X. The dongle worked fine for weeks on Yosemite. It is a Cable Matters Cable Matters USB 2.0 to 10/100 Fast Ethernet

After i updated to mavericks, my usb ethernet adapter stopped working.

I'm not sure why, but when I updated my software to mavericks, my USB ethernet adapter stopped working.

I'm using that adapter:

After I updated to Mavericks, I installed the driver in this page, but it didn't work. Then I googled "AX88772" which is my adapter's part no. or something like that, and I installed that one:

I wasn't expecting that work but that did work. So, I think the solution of the problem is finding the right driver. I hope you solve your problem too.

Network drive: move between USB/ethernet modes causing icon loss

hi
i am still setting up my new ethernet network drive.
the drive is both ethernet and USB compatable, and is HFS+.
files are losing their icons etc when i switch from USB mode to ethernet and vice-versa
ie, when i save a file with the drive connected by USB, then disconnect and restart in ethernet, many files have lost their icons and i can't open them without assigning an application via get info.
the same happens in reverse—many files saved in ethernet mode lose their icons etc when i go back to read the drive via USB.
the problem is only happening to files without extensions and also to alias files.
is this a problem, or normal behaviour?

greetings from a sunny morning in sydney australia
ok — i have reformatted the drive using disk utility (connected via USB) to HFS+. i have copied about 50GB of data. all looks good. then i shutdown, remove USB connection and connect to drive via airport>wireless router>switch>ethernet cable>drive. in this mode, files with generic extensions (.mp3, .mov, .jpeg, .doc, etc...) are visible as usual with the usual icons. folders are also normal.
BUT, any file the name of which does not have an extension, and any alias file (not having .alias) has changed to a 'unix executable file', the icon changing to a small black 'terminal window' picture or a what looks like a little creature with big eyes and horns (not kidding!). there also additional files with such icons — desktop DB files and the like.
this is done with only one share (top level, the drive itself) and no users or groups, just an admin login in both times.
so everything works fine, except some kinds of circumstances resulting in weird icons and 'unix executable files'.
thanks again for your patience and assistance

MacBook AIr usb ethernet slow when connected to second switch

Hi,
We have MacBook Airs with 100 Mbps Apple USB ethernet adapters.
We have managed Cisco switches for the LAN.
We experience fast speeds when a USB etherenet/MacBook Air is connected directly to the switch.
However... if we introduce a second switch between the MacBook AIr and the main Cisco switch we experience horiffic slowdowns for some (not all) network activity.
For example, we have IP phones with ethernet passthrough. They work great with iMacs and Thunderbok Macbook Airs. However, if we connect a MacBook AIr/etherenet adpater to the ethernet phone, we expereience a horrific slowdown when using Apple Remote Desktop Manage > Copy items... (and also on connectoins to an in-house database). It's probably 15 - 20x slower than when connected directly to the Cisco switch. Other network operatoins work at expected speeds an the Air.
It's not just connecting to IP phnones that causes this problem. If I use a Netgear 1000/100 switch on the desktop, set up as
MacBok Air USB ethernet > Netgear > Cisco
we have the same horrible slowdown for some network operations.
I purchased a 3rd party USB adpater, but had the same results.
Can anyone shed any light on this issue, please? Is there a setting onn teh CISCO switch that is causing the problem? Any know problmes with USB etherenet on MacBook air.
Many thanks,
b.

Is this a question? A complaint? Nothing any of us can do about that, and this is a well-documented and well-known issue.
It doesn't effect most MBA users who most likely use wireless for most of their transactions, and the times you need to use ethernet, you are right, it will run slower.
Just curious I have a pretty fast 5N wifi network. If I'm setting up a new MB Air from another laptop is it going to be faster through the ethernet adapter or the wifi network?
