So with the lack of Gigabit ethernet options on the Macbook Air, I'm kinda hoping that some bright spark on here is going to shower me with suggestions on what 3rd party adaptors are available/been used...! ;)

I've had a real good hunt around, and the only adaptor which I can find that people have got excited about (back in 2009!) was the Buffalo one... Annoyingly, this is pretty much nowhere to be found...

I'd really appreciate any suggestions from people here! The one thing stopping me from getting an MBA is the gig-e problem. As I use time-machine for backups, and transfer relatively large files around between offices<->datacentres<->home, it's rather important!

Thanks in advance! :)

Remember that USB 2.0 tops out at ~35MB/s in real world while Gb Ethernet can do up to ~100MB/s in real world so USB will be bottlenecking the performance.

I've ordered this from TigerDirect. Sabrent has a 10.5.x and above driver that I'll be using for it.

It's Gigabit, which even with the USB2.0 bottleneck should still be ~3x faster than 100BaseT. For the price it's definitely worth a shot.

Not it's not.
300 mbit/sec is a number on a paper...

Arstechnica had a huge test featuring several different n-routers and from 1 feet from the router the fastest one managed 81.8 mbit/sec. At normal distance people actually sits from the router you'll get even less. 100mBit ethernet is faster than 802.11n wireless in the real world! (http://arstechnica.com/hardware/reviews/2007/11/802-11n-router-roundup.ars/)

I have network storage at home, connected thru GBit-ethernet, and I guess there is about 5m with cables from my MBP to my storage server. You would think that the bottleneck here would be the disks, but no, fastest thought put i can get over the network is about 30MB/sec.

So in real life, how does this compare?
Gbit ethernet is about 3-4 times faster than 100Mbit, which is slightly faster than 300Mbit 802.11n wireless...

Are those internet speeds or the speeds when you connect to your network server (if you have one?)

If it is the first, then even the Ethernet adapter I linked to with its 11MB/s will be faster when connecting to a local network.

The speeds you posted would mean, a 1GB file would take 5 minutes to transfer, 10GB would take 50 minutes. With a wired 10/100 Ethernet connection, it would take 1m 30s for 1GB or 13m 36s for 10GB (estimates). With 30MB/s it would take less than 40 seconds for 1GB and less than 7 minutes for 10GB.

This is really dumb. You are comparing internet speeds.

I can easily get ~300-400mbps from my NAS to HTPC over GigaE. On N-wireless, maybe 50 mbps, if I am lucky.


As for the OP: It is probably not a good idea to buy a MBA, if you need the GigE.

I know what you meant, USB would be the bottle neck. However with the ethernet adapter that Apple is selling the bottle neck is the 100Mbit (which is only ~10MB/sec - 11.25ish to be exact for some people in this thread, but still the same point) USB is capable of up to 480Mbps, but does seem to only sustain speeds a little less than that or about 30-35MB(bytes not bits) per second. So if apple sold a 10/100/1000 adpater which costs just pennies more you would still move stuff at about 3 times faster than you would with the 10/100 adapter they are selling you.

Not it's not.

First off - I was talking about gigabit speeds, not 802.11n - just so we are on the same page. I run gig-e at home with Windows Home Server & several HTPCs in the house. I routinely copy blurays around between the HTPCs and my WHS and sustain 60-70MB/s (~600ish Mbits/sec) and if I used jumbo frames I could sustain even faster than that. My server is on the 3rd story of my house and one of my HTPCs is in the basement. Distance of wired networks isn't as critical provided you use the correct rated cable for the speed.

While it's still the bottleneck gigabit over USB would still be faster than 100Mbit over USB.

OK, so to give you some idea of actual throughput and various bits and pieces which need to be taken into consideration (funnily enough, it's my day job :)). The distance of cabling, the quality of cabling, the type of hardware you're using, and much more. Most desktop switches will handle a good whack of bandwidth, but don't really expect 125MB/sec (or 1Gb/sec).

The main reason for me wanting Gig-E rather than going down the wireless route is exactly what someone above has said, you don't get the true speed. If I can get 150-300Mb out of a USB adaptor, great! Means I'll be able to do my transfers a hell of a lot more quickly. Generally, to speed up a majority of my transfers, files are "archived" into a zip, as trying to transfer many small files vs. fewer larger failes will be much quicker.

Additionally, what I do when I move stuff from home to my girlfriends place (iMac QuadCore i7) I use a crossover with my (pleased to say) almost 3yo MacBookPro. From that I get around 10-30MB/sec, which is fantastic in my opinion. To actually max out 1Gb/sec requires some fancy disks. :)

I haven't actually bought the Air yet, and was looking to see if people had any first hand experience in products/solutions to the problem. Problem I have is, my poor MBP has been dropped, dented, dropped again so needs really to be replaced. The HD is going, and I can't bring myself to buying ANOTHER battery as it's showing "Service Battery" again. I think this would be my 4th battery! So, maybe time for a change...

Anyone tried it before?

I have not used this particular product before but I have used usb-> ethernet adapters before and they work ok. I had an old dell laptop that did not have any ethernet ports. This worked ok, but was slower then an actual ethernet port.

I suspect that even with usb2, it will be slower then an actual ethernet port.

I asked already but I'll re-ask. Why buy a laptop that fails to have an ethernet port when you stated that is all but a requirement.

If I were to buy an expensive laptop that failed to meet my initial needs and requirements, I'd envision frustration as I attempt to work around that short coming.

Stingray454
Nov 3, 2010, 07:19 AM
I've tried similar solutions in the past, ie, buying a product I really wanted but lacked important features, and then trying to make up for those features in other ways. What I learned from that is it's not worth the hassle, and the solutions you come up with are often expensive and not very good. The options as I see them:

* Get a MBP and enjoy Gbit ethernet
* Get an Air and enjoy the design / portability, and spend a little while longer transfering files.
* Find a better solution for moving data. This might not be possible, but I'm talking about cutting down on the amount of files you need to move, start using dropbox / similar to only move the active document, always keep your files on a USB drive and work with them from there or something similar.

Because there are USB adapters to provide that. Just like there are dongles for HDMI. Just like there's an external power adapter for every laptop (do you not buy a laptop just because power is a requirement and there's no adapter built directly into it???).

USB 2.0 is much faster than Fast Ethernet 10/100 speeds, it is very easy to saturate 100mbps. Very few GigE connections ever get fully utilized - the 480mbps provided by USB 2.0 is theoretically 4.8x the speed, but basically you can get USB hard drive speed like connectivity to a network share that's capable of operating at such speeds.

Its a question of what you want integrated, vs. what you want as a peripheral device. Everyone has different needs and requirements. Is that really so hard for people to understand? :confused:

Yes, but the OP stated that he speed/volume is an issue and those dongles will not provide gigabit throughput. If he's happy with 10/100 speeds, then yeah the dongle is ok.

neteng101
Nov 3, 2010, 08:07 AM
If he's happy with 10/100 speeds, then yeah the dongle is ok.

But he can get sub GigE but faster than 10/100 speeds with a 3rd party GigE USB adapter. He's asking if there are any available.

Unless you're assuming he's expecting GigE to mean 1000 and nothing less than that will suffice, in which case, then yes he should be looking elsewhere. I don't read it that way - I think most people looking for a GigE USB adapter would understand the limitations - and up to 4.8x over 10/100 is no trivial improvement to be passed up on if its available.

You're saying if he can't get 1000, then he has to settle for 100 or 10 only?

Maflynn, I'm thinking that may be correct. His latest post suggest he's done some more research and this Belkin is the best candidate, which suggests he's either not really read, or not taken to heart, the discussion in the thread up to this point.

But local networks can offer up to 70MB/s (MB as in MegaByte), if one uses Gigabit components. If a USB to Gigabit Ethernet adapter can provide full USB speeds, then one can accomplish data rates of up to 35MB/s, something the OP is after, as s/he is talking about a local network and not the internet.

Yes. The Monoprice one works fine for me. Did you install the drivers that came with the dongle? They are on a mini CD included with the device.

Although OS X seems to recognize it out of the box and the Asix website says that the chip inside is compatible with 10.6 as is, I found that you needed to install the Monoprice drivers for Mac included with the dongle.

Some real life data:

My gigabit-connected PC can transfer files to my NAS at 72MB/s (measurement from teracopy).

With the Monoprice 'gig' dongle, I can transfer files from Macbook Air to the same NAS at 28MB/s (measurement from ultracopy, and bursting to 32MB at times indicating there is possibly some optimization I could do if I cared). I also got 28 MB/s in PC to MBA transfer (teracopy).

Not as good as a true GigE, but better than the 10/100 dongle would do and better than my Wifi can do.

Thanks for this. I had the same problem. The drivers on the CD worked for me. Although accessing the mini CD was an issue because I only have a Super Drive, which doesn't work with mini CDs. I've attached a zip file with the drivers that are on the CD in case anyone else is in the same situation.

a quick question: what is the maximum speed of MBA wireless connection?

So many people don't understand the difference between internet speed and local network speed?

Generally not. I have a gigabit switch so I can maximize the network traffic between computers. Since I'm on DSL, the overall internet speed is quite a bit slower and in fact my wireless is faster then what I get from my dsl connection.

If you are mainly concerned with hotels that only have ethernet this really shouldn't be an issue.

Get the USB adapter and deal with it. I have yet to stay in a hotel that has very high speed internet access (wifi or wired). It is highly unlikely that you will be in a hotel that offers greater than 30MB/s download speed.

Is your post an answer to the OP?


So with the lack of Gigabit ethernet options on the Macbook Air, I'm kinda hoping that some bright spark on here is going to shower me with suggestions on what 3rd party adaptors are available/been used...! ;)

I've had a real good hunt around, and the only adaptor which I can find that people have got excited about (back in 2009!) was the Buffalo one... Annoyingly, this is pretty much nowhere to be found...

I'd really appreciate any suggestions from people here! The one thing stopping me from getting an MBA is the gig-e problem. As I use time-machine for backups, and transfer relatively large files around between offices<->datacentres<->home, it's rather important!

Thanks in advance! :)

anyone?

I think my wireless router can handle 54Mb/s which should be just under 7MB/s.
So is the wireless speed of the MBA over that?

thanks

Some real life data:

My gigabit-connected PC can transfer files to my NAS at 72MB/s (measurement from teracopy).

With the Monoprice 'gig' dongle, I can transfer files from Macbook Air to the same NAS at 28MB/s (measurement from ultracopy, and bursting to 32MB at times indicating there is possibly some optimization I could do if I cared). I also got 28 MB/s in PC to MBA transfer (teracopy).

Not as good as a true GigE, but better than the 10/100 dongle would do and better than my Wifi can do.
This sounds very promising. I was reading in some of the customer reviews that DHCP does not work with GigE on the MacOS. is this really plug- and play after installing the drivers?

Yes.

The driver install of the Monoprice drivers requested a reboot, but I had no other issues. It worked immediately after reboot. Both manual and DHCP settings worked (neither manual nor DHCP worked for me without the custom drivers). One minor but convenient feature of the Monoprice dongle is that the MAC address is clearly labelled -- I set up all my devices on my local network with reserved IPs via DHCP and so was able to quickly and immediately configure the connection with my router.

My experience echoes this one with the Sabrent device, which is based on the same hardware. I was unable to get it to work properly with stock drivers, but the 10.4 drivers on the disc got it working just fine. Top speed so far is 24MB/s with a 3GB file.

It does deliver about 20MB/s compared to 13MB/s for the Airport card on my 13 in MBAir.

Not a huge improvement but it is consistently faster.

That's to TC. Maybe to a server or nas would be faster

In theroy a USB gigabit adapter could transfer at 480mbits (the max transfer speed of USB) vs the apple adapter at 100mbits. In reality I am getting 30.8MB/Sec or 246 mbits with my Monoprice adapter. In reality the monoprice adapter is cheaper too. It was about $24 with shipping.

That's pathetic that Apple would sell the bad adapter. Has anybody confirmed that the Apple one is indeed limited to 10MB/sec? Just wondering if this is indeed a hard limit...

The apple adapter is 100Mbit/sec instead of 1000Mbit/sec so in the case of the apple adapter you are limited by the 100Mbit/sec. With the monoprice adapter you are limited by the USB speed. It should be at least 2x as fast if you are running a gigabit network. If you are only using a 100Mbit network it won't matter.

Thanks guys. The Monoprice one can be bought unbranded, so I've managed to track this down for people in the UK to the Startech.

Vendors who sell it here in the UK are:

Ingram Micro UK V931192
EntaTech STH-USB21000S
UPC Code 065030840064

I've just bought my MBA, really happy with it, rather nice and zippy, a little heavier than I thought... My girlfriend got the 11" which is a rather sweet piece of kit. The screen real-estate was the crunch point for me, so went for the 13".

I'm planning on ordering 4 of these adaptors, so will post back probably on Wednesday/Thursday to let you know if they're working or not! :)

I doubt that. Apple doesn't advertise anything of the sort, seeing as how they just come up with their own random names for everything anyway. They will just call it Ethernet Adapter Extreme or something.

I doubt you could sue them for not having an "extreme" enough network connection ;)

Wow! This discussion is getting too techie for me! I bought the Apple USB Ethernet Adapter with my MBA 11 to use where they only have Ethernet connections at hotels, etc.

I have a content need to be able to use such a connection at my timeshare Condo on the Oregon coast. They supply free internet. One gets a little black bod that plugs into the power socket and then has an Ethernet cable that goes from the black box to your computer.

I haven't been to the Condo since buying the MBA or the adapter; however, I'm hoping it will work just like my 12" G-4 notebook has in the past.

The only test I've done on the adapter is to turn of my WiFi and use my USB Ethernet Adapter connection on my home network which worked just fine! ;) :apple:

If we only ever need it to connect to one router, we just set a static IP on the router and then use the same one in sys prefs?

Though hat will limit you to USB speeds (25 to 35 MB/s).

And the above posts ....

This adapter limits you to ~12.5 MB/s since it has a 100 MBit/s ethernet port.

Plenty of clones of the Asix on offer on eBay at less than 15, so no VAT considerations for UKers or possibly Finns, too, if you are prepared to wait a little for shipping from China.
