Wi-fi 802.11ac USB adaptor

I bought the Edimax AC450 USB Adaptor for my Macbook Air. There is a utility installed with the adaptor, but this will not open up with Yosemite. I have been able to open it on another Macbook with Mavericks, and it worked. Same problem with other wireless utilities like Railink. I have seen how some instructions can be written in into the system to allow this. Any solutions?

Yes, apparently it is a recognized problem with Yosemite with these wireless utilities. I will check again, though. I am not that much of a geek that I change instructions in the Mac, and I just sent an email to Edimax. Thanks!

Will a 802.11ac USB adapter work on IdeaPad U530?

I recently purchased an IdeaPad U530. Around the same time, I purchased a NetGear Nighthawk AC 1900 Dual Ban (R7000) router. All of my other devices connect no problem to the 5ghz wifi network from the router. I realized the 5ghz band didn't show up on my U530, but the 2.4 ghz network appears.
I did some investigation and found my new Lenovo laptop has a 7260 b/g/n card. I thought, "That will be a simple fix, I will just replace it with an AC card." Then I read:
http://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/IdeaPad-u530-upgrade-to-802-11ac/td-p/13106...

https://forums.lenovo.com/t5/General-Discussion/WWAN-and-wireless-card-BIOS-whitelists-Lenovo-COME-O...
That was when I "unhappily" learned about Lenovo's "whitelists" for the first time. I'm shocked that in 2014 I simply can't replace the wifi card in a laptop. Had I learned about this sooner, the Lenovo would have gone back to BestBuy on principle.
I'm a basic user and I don't have the technical skill or time to deal with flashing BIOS, etc. . . so I have three questions.
1. Will the Lenovo U530 allow me to use one of the 802.11ac USB adapters?
2. Any recommendations on which USB adapter to use?
3. Do I have to deactivate the Intel 7260 card before using the USB adapter? If so, how do I do that?
Thanks!
Solved!

1. Will the Lenovo U530 allow me to use one of the 802.11ac USB adapters?
IMHO why not? I use a usb dual wifi adapter myself although it's only a,b,g,n. It is more efficient than the built-in card.
2. Any recommendations on which USB adapter to use?
Try going to Netgear's site and look for an AC dual band usb adapter to match your Netgear AC router.
3. Do I have to deactivate the Intel 7260 card before using the USB adapter? If so, how do I do that?
To avoid getting the system confused and make the setup of the usb adapter easier I think you can disable wifi in the bios. You will still have bluetooth functioning.

Using 802.11ac USB adapter on Mid 2010 Mac Mini Server

I recently read an article about the 802.11ac connection and it mentioned if you use a USB adapter on a USB 2.0 connection you will lose much of the intended speed. Does anyone know if there is a way around this, like a FireWire USB adapter or is it possible to install a USB 3.0 port on my Mac Mini?
I looked at my PHY Link Speed in the Network Utility and it matches the 802.11 Adapter specifications of 867 Mbit/s.

Best 802.11ac usb adapter?

Looking for some guidance here... I need a USB adapter to "test" and demonstrate the 3700 802.11ac AP's in front of customers and I want something that is going to give me the best throughput possible... but also be reliable.
I know I will need to be in close proximity of the AP and I know that I would get better throughput with an internal wireless adapter but one of the requirements is that i need to demo with a USB adapter.
What have you guys used and what would you recommend I use or stay away from?
Thanks in advance!

Ended up purchasing a Rosewill AC1200UBE 2.4/5GHz USB3.0 adapter on Amazon ~$40
The adapter specs state "Data Rates of up to 300Mbps" for 2.4GHz and "up to 867Mbps" for 5GHz
Testing between that and another laptop, through a Meraki MR34 showed actual throughput of 400Mbps from 10 feet away and just shy of 300Mbps 2 (drywall) offices away with the door closed. 25-30 feet down the hall in our office building I got about 175-185mbps throughput.
Not too bad, considering it's only rated for a Data Rate of 867Mbps and not the full 1.3Gbps. I'm guessing the adapter only supports 2 spatial streams.
Anyway... just thought I'd throw that info out there in case anyone can use it.
Attached is a snapshot from DUMeter running on the laptop with the wireless card. DU Meter running on the laptop that the traffic generator was pointing toward also showed the same results.

Yoga 13 Wireless Fix - far better range and speed using 5G Linksys AE6000 .11ac usb nub

$60 Linksys model AE6000 802.11ac USB hub has made my Yoga 13 a useful device. Benefits are as follows, along with a quick "how to" tutorial.
Far better range from my access point (80 feet with reasonable speed on Linksys vs. 30 feet using built-in Realtek WLAN card.
Significantly faster speed 55 meg/sec using 5G, compared to stock Yoga/Realtek's 2.4 GHz-limited 14-16 meg/second download speeds - both tests done same day using Ookla Speedtest.net)
No longer crashing after resume (I suspect the crashing that began with Win 8.1 is due to driver issue)
Recognizes both 2.4 GHz and 5 GHz WLAN networks (Windows 8.1 failed to recognize 5GHz signal until I backdated the Linksys WLAN driver to use Windows 7 driver).
TUTORIAL / STEPS:
Turn off (or at a minimum - review before downloating) windows updates - otherwise Win8.1/Yoga will over-write the good driver you're about to install and revert you back to slow WLAN performance. Give Microsoft 6-12 months & maybe they'll get the drivers right for their POS Win 8.1.
Create a restore point.
Download & the Windows 7 (yes, seven) drivers to a folder on your Yoga.
Then open the following folder:
C\Windows\System32\drivers
Locate the file named "netr28ux.sys" and move it to a new folder you create on your desktop (for safe keeping)
Download the Windows 7 x64 drivers for the Linksys AE6000 and the installation/setup program from the Linksys support pages here
http://support.linksys.com/en-us/support/adapters/AE6000
Extract those Win7 x64 files (including the netr28ux.sys file) into their own folder, then copy the extracted files to the
C\Windows\System32\drivers folder.
Run the Linksys AE6000's little setup utility, insert the little nub into your USB port, complete running the setup utility, type in (or select) your network, type in your password & select your encryption type, and you should be in good shape.
I turn my onboard "WLAN 1" card off using the right-swipe/charms, and the Linksys shows up as "WLAN 2" with the networks it's picking up.
CAVEATS:
The Linksys AE6000 occupies one your USB ports, but the Linksys AE6000 seems to have the smallest size (barely 1" sticking out) and was rated the fastest of its size by PC Magazine. Very good performance for .11n and .11ac environments.
This mod may not be for everyone. I was able to barely tolerate the Yoga's wireless limitations since purchasing in May, but the Win 8.1 rollout (along with what must be craptastic drivers) was the last straw. The system began behavng erratically, crashing after resume, and wireless was even worse (speed degraded to 1 meg/sec or less up and download, within an hour after a reboot).
I have not checked the impact of this nub on battery life. I suspect it may be a little worse than stock, but it may be a reasonable tradeoff for me to actually be able to travel more than 30 feet from my router/access point (and have YouTube stream in FHD without stutters/crashes).
BACKGROUND:
After Windows 8.1 update, my Yoga 13's wireless performance went from barely adequate to useless (crashed on resume, speed degradation an hour after fresh boot, etc.).
I'm sharing this info because I've enjoyed this machine's other assets so much. It's too bad we can't replace the Realtek WLAN card, and obviously Lenovo though enough of our issues suffered that they chose a different card for the Yoga 2 (although the antenna design still may be partly to blame for some of those performance issues as well). Love the keyboard, display, etc. and can put up with the fan noise (if someone has a fix for fan noise though, please post to this thread or point me to the fix).
Best of luck with this potential (relatively inexpensive) work-around. It's not as ideal as switching out the internal card, but I'm pretty pleased so far. If there are other wireless fixes, please share on this thread.
Thanks,
Stanford

Having used this thing for a couple of weeks now, I'm still amazed at how great the network performance is and how it's transformed my Yoga 13 into a near-instant device around the house (incl range that extends to the garage and perimeters of front & back yards. And traveling is pretty phenomenal too - great speeds at the hotels we've visited (instead of having to tether my 4G phone because Lenovo's weak-sauce wireless couldn't hang onto a 1-bar connection for 3 minutes).
It's a small tradeoff in having a 1" by 1/8" inch "nub" stick out of a USB port, but one of the best $60 upgrades I've ever done. Highly recommended.

What network adaptors support 802.11ac?

I want to purchase the new airport/time capsule mainly for it's 802.11ac capabilities. I have a mid-2009 macbook pro.
Wondering what network adaptors are out there that I can plug into my usb that can support 802.11ac? I found some but they only support Windows.

Newer AC wireless would need to support USB 3 standard but of course that is not available.
I want to purchase the new airport/time capsule mainly for it's 802.11ac capabilities. I have a mid-2009 macbook pro.
You only have one port that is near capable (actually more than capable if real numbers are used) and that is ethernet. So the best device for you is a second Airport Extreme working as bridge or extend wireless in apple terminology.. really it is not such a bad option since the cost of AC usb 3.0 will be over $100 anyway.

USB Printer with Time Capsule (with 802.11ac)

Hello Guys,
I have a Canon MP258 inkjet printer and it's not working with my airport time capsule (with 802.11ac) .
I had tried a lot of method to solve it but it can't be done.
Pls, help me to solved this puzzled.Thx
Best Regards,
Johnremy

If the name of your printer does not appear in the printer list when you click the + button, try contacting Canon Support to see if they have an updated printer driver that you could download and install.
Download Free Driver Pinter Canon Pixma MP258
http://filedir.com/drivers/printer/canon-pixma-mp258-mp250-printer-driver-downlo ad-516940.html
If this does not work, then Canon has not provided the printer driver for their device to operate on a network USB connection.
Do you understand that if you can get the print function working, that fax, scan, copy, maintenance, etc functions will not work when the MP258 is connected to the USB port on the Time Capsule?
Only the print function is supported on the Time Capsule, so if you need the other functions, you should connect the MP258 to your computer.....not the Time Capsule.

Connected a usb HD to the new airport extreme 802.11ac; how can I see the HD on my iPad?

I just purchased and set up the 802.11ac airport extreme. I have connected an usb HD; I can see it from my iMac and my MacAir laptop. Can I see the connected HD from my iPad air 2?

You can, if you install an App like FileBrowser on the iPad. Info below:

Airport Extreme 802.11ac and USB disk failure

hi,
Had an Airport Extreme 5th gen with a USB disk attached for over a year of which my Mac was using Time Machine and creating backups no problem, didnt skip a beat.
Just bought a new Airport Extreme 802.11ac, attached the same USB disk and Time Machine works once or twice then fails saying it cant find the disk. True enough if I open finder and try and find the disk its not listed.
Opening the airport utility it shows the disk attached. If I reboot the Airport Extreme the disk shows up again in finder for a short period of time.
Looks like they released a firmware update 7.7.1 which was supposed to fix this but it seems in my case it hasnt. Even factory reset after the update but no joy.
Normal wireless activities like internet access etc are fine.
Not sure if anyone else has experienced this yet? If not I guess ill try a non self powered disk or something, either that my AE is faulty.
thanks
matt

My experience with the 802.11ac extreme with 7.7.1 firmware suggests Time Machine doesn't work when the name assigned to the device (not the SSID) contains a period, which the out-of-the-box name does.
Out-of-the-box, with the default device name still assigned, I could not get Time Machine to recognize the remote disk on multiple 10.8.4 Macs until I created an empty folder on it. Yet once registered with Time Machine, backups never occurred to the disk--TM status was always "waiting". The server name displayed in TM had the period in "802.11ac" escaped with a backslash (i.e., "802\.11ac").
I renamed the extreme, but used a name that still contained a period. The same difficulty was encountered registering the disk with TM. Once registered, TM status for the disk was still "waiting".The server name again had the period escaped with a backslash.
Finally, I just removed the period from the name. Registering the disk with TM then occurred normally and backup began immediately.
(In an earlier case with the 7.7.0 firmware, I had no trouble registering and backing up to an 802.11ac Time Capsule that had previously been given a name without a period in it.)

New Time Capsule (802.11ac) issues reading files on USB drive

My 802.11ac Time Capsule reguarly fails to read .mp4 files stored on an external HDD drive connected to the Time Capsule via USB. All the files were tested as working when they were copied over, then for some unexplained reason the Time Capusle refuses to recognise them when they are accessed at a later time. This happens for about 1 out of 3 files (sometimes more). All the files are .mp4 format video files. Detacthing the Seagate drive from the Time Capsule and connecting it directly to the MacBook Air fixes the problem and allows the files to be read and played normally – this indicates the problem is with the Time Capsule, not the Segate drive.
Symptoms;
1) iTunes generates a file error with trying playing the video from iTunes,
2) selecting the file from Finder no longer generates a playable preview thumbnail as the Finder preview box remains blank (white),
3) attempting to play the file from Finder generates an unrecognisable file error in QuickTime,
4) connecting the external drive directly to the MacBook fixes the problem (the file can be read and played normally),
5) the files remain readable after reconnecting the external drive back to the Time Capsule, however the problem just reoccurs again later.
My normal use case is playing movies and TV programmes from iTunes to my television via Apple TV. Apple TV plays the video files over WiFi from the iTunes Library on my MacBook Air. The video files in my library are physically located on the Seagate external HDD attached to my Time Capsule.
I use a mid-2012 MacBook Air 13" running Mountain Lion 10.8.5. I have an 802.11ac (2 TB) Time Capsule (latest firmware 7.7.1) with a Seagate (1 TB) GoFlex drive attached (to the Time Capsule) via USB 2.0 (USB powered). The Seagate is my media drive and holds all my movies and TV programmes (all in .mp4 format). Both drives are Mac OS Extended (Journaled) with single partions. Time Capsule network is set to Bridged mode to resolve double NAT. I have an Airport Express extending the wireless netowrk to my MacBook Air. Prior to errors occuring, all files tested ok as follows; file plays ok locally on MacBook Air, files play ok from Finder after being moved to the Seagate, files play ok from iTunes library (pointing to Seagate).
Disk Utility verifies the Seagate drive has being OK. No other network issues.

Problem Solved!
The 1TB external HDD attached to my Time Capsule was divided into 2 equal partitions. The first partition used to be my Time Machine backup which I deleted and made available as free space. The second partition was the one I was copying to. It seems the Time Capsule has a problem with blank partitions on an external HDD. Once I repartioned the drive into a single 1TB partition, everything worked fine and my Time Capsule no longer crashes.

Does anybody know of an USB 802.11ac Wifi adapter that is supported by Yosemite 10.10

Ever since upgrading to Yosemite 10.10 my WiFi is slow on my 2007 IMAC. I am trying to find a USB wireless adapter that supports 802.11ac and runs at MHz. So far I cannot find anything

Late 2013 rMBP 13" 802.11ac problem

I've got a brand new 13" Retina MacBook Pro 13" (the 512GB i5 model)...and after a rather strong showing at first, it falls absolutely flat when attempting to connect to the 5GHz side of my wireless router.
Specifically, this:
Current Network Information:
yannnet 5G:
PHY Mode:          802.11ac
BSSID:          10:fe:ed:xx:xx:xx
Channel:          149
Country Code:          US
Network Type:          Infrastructure
Security:          WPA2 Personal
Signal / Noise:          -56 dBm / -92 dBm
Transmit Rate:          27
MCS Index:          1
As you can see, this isn't a weak signal problem. In fact, I've got multiple other devices (mid-2009 MacBook, 27" 2011 iMac, Nexus 5, iPad third-gen) that connect to that network just fine, whether at 11ac speeds (the Nexus 5, at a full 433 Mbps since it only has one antenna) or at 11n speeds (for all other devices).
2.4GHz appears to have sporadic issues as well, but it's better than 5GHz. Ethernet via a USB 3.0 adapter seems to work fine.
I've got Mac OS X 10.9.2 installed. Any idea what's going on here? I've cleared preference plist files etc., and that only seems to help for a minute or two.

Go ahead an exchange it for a different machine - 95% health is just not acceptable for a new machine.

HT202807 I have a MB Air 128gb and a Time Cap.802.11AC. My HD is maxed out because of 30GB of photo storage after migration to 10.3.3 Photos. Please recommend an external drive best for connecting to TC and moving the iPhoto Lib off my HD

I have a 13" mid 2011 MB Air 128gb and a Time Cap.802.11AC. My HD is maxed out because of 30GB of photo storage after migration to 10.10.3 Photos. I have reduced apps and files as much as possible so the only thing left is to move the photos. Please recommend an external drive compatible for connecting to my TC 802.11ac and moving the iPhoto Lib off my HD which will free approx 15 gbs. of space. I don't plan on using it for any other purpose so a small capacity drive will suffice. I know the "optimization" is supposed to adjust for this condition but I don't trust that assertion.I only have 2gb free space remaining.

I don't plan on using it for any other purpose so a small capacity drive will suffice.
If you really only want such a small capacity drive.. what about just buying a 32GB or 64GB USB memory stick.
You should still have a back up to the internal hard disk of the AC TC.
Or just buy a WD Passport.. don't waste your money buying 500GB as it is only a bit more to buy 1TB and a bit more again for 2TB.. For future use if you do buy a USB hard disk buy 2.5" type.. and buy 1TB or if the budget stretches 2TB..

Will time capsule support Airportextreme 802.11ac and an external hard drive on my iMac (late 2011) with Yosemite?

I want to set up a new Airport extreme 802.11ac with an external drive as a wireless back up for time capsule. I have an iMac (late 2011) running Yosemite. Will this work, and if so, what are the recommended external hard drives that work the best.
The rationale for not buying a time capsule is that I have had 2 hard drive failures and replacements on both my iMacs and I am afraid if the time capsule drive fails, it will be yet another apple hard drive that has failed on me. I currently back up on G drive external drives.

Apple does not make hard drives. They may be using the same drive that's in your G-Drives.
You can backup to an external drive connected to the newest AEBS via USB.

Speed Tests Results for 802.11ac Wireless Connections

Using the new Apple MacBook Air with 802.11ac wireless, I tested copying a file and a folder to both the new 802.11ac AirPort Extreme router housing a USB-connected hard disk and the less recent 802.11n Apple AirPort Extreme router housing a similar USB-connected hard disk.
The results of the tests are summarized in the table below. The movie file was ripped from a DVD movie, and the Microsoft folder is simply the Microsoft Office 2011 folder in my Applications folder containing 14,231 items.
The MacBook Air computer was located 6–8 feet away from each router with no intervening obstructions. While this was not a scientific test, it demonstrated to me that 802.11ac wireless is clearly superior to 802.11n in a real world setting. I assume that the lower relative performance of 802.11ac versus 802.11n for the large folder containing many files is due to overhead in copying and writing files from and to the hard disks. Ditto for the Gigabit Ethernet test.
