Wireless speed of new iMac

What's the maximum speed of the wireless connection of the new iMac (27") ?
is the Mac running at 2.4Ghz or 5Ghz...
and 20Mhz or 40Mhz?

Welcome to Apple Discussions!
Wireless speed is not measured in Ghz. It is measured in bps. 802.11n is typically between 100 and 200 Mbps depending on local interference. That said, any other device sharing the wireless network at the same protocol will slow it down often by a proportionate amount if it is constantly sharing the network. Any device using it on a slower protocol, will slow down the wireless network to the slower protocol. Draft 802.11n often is only 54 Mbps, and so is the 2.4 Ghz in many instances when it is non-Apple. 802.11g for instance is 33 Mbps. 802.11b is about 12 Mbps. If your wireless router is set for using both 802.11n and a slower protocol, it generally will only slow down when a slower device is connected. Note these speeds are only good for devices sharing the same router. Apple's routers also have 100Mps and Gigabit ethernet, which would decrease the shared network speed with ethernet devices accordingly. You will still see the slower speed of your internet connection still be the maximum speed for data transfer over the internet.

Slow wireless speed with new iMac Intel- problem with 802.11g?

There IS a problem with the new Intel Mac, I have tried both the Intel iMac and the new Intel Mac mini and they both have the same problem with slow wireless speed (or rather it variates, if I do a ping to another computer on the network the speed goes from < 1 ms up to 1000 ms and then down to < 1 ms and so on). The older mac minis, my Linux boxes and my Windows PCs don´t have that problem. I have also read reports on the net and it appears that most users experiencing this problem have wireless card firmware version 101.3 (3.120.28.3) . A possible "fix" is to change to 802.11b on the router and then it works. No speed fluctuations and a stabile network! I know it is a bad solution, I would prefer to use 802.11g and get the speed. However I think this points to a problem with the drivers regarding 802.11g. I am starting up a new thread on this and those of you with problems, please try to switch to 802.11b and if it works let us make Apple aware of this.

Slow wireless downloads on new iMac

I just picked up the new iMac and downloads are EXTREMELY slow and the router is only 10 feet away from the Mac. Any ideas what could be wrong?

I run into the same problem when I got my new i7 imac in December 2012.
It run 10 times slower via wireless on speedtest.net vs my 3 years old macbook pro.
I soon as I plug in the network cable it runs super fast, but wireless is just beyond terrible.
I did test new iMac vs my old Macbook Pro parallerly many times, same network, same time of the day. I did reset the router, modem, wireless card, you name it,
I called apple and they first tried to repair my brand new computer?!!? They did the speed tests via phone and couldn't figure out the issue.
After an hour or so on the phone, and being transfered from one person to another they finally agreed to ship me a replacement iMac.
So now I waited 1 month for my custom ordered replacement iMac.
Now check this out....The new one just arrived today and it has the same issue?!?!
I think we need Steve back to get this straightened out. Someone help please.

What is the best wireless printer for new iMac w/Lion?

I just bought an iMac (Lion) and now, I need to buy a new printer since my old one is not wireless capable (HP Photosmart C5280 All-in-One). My old G4 is still up and running (using it only for Adobe CS2 until can afford that upgrade) and the printer works fine. However, the iMac will not be in the same place as the G4, so I need a wireless printer.
I would also like the new printer to play nice with a PC laptop (husband's for work) as well as be able to eventually print from an iTouch and iPad.
I may be asking a lot, I know.
I would buy AirPort if I knew it worked with my current printer, which would be great... but from what I've been able to research, that isn't possible with this model. I will eventually end up buying AirPort at some point in the future, but right now a printer is my focus and I would prefer not to buy both right now.
So my question is...what printer would be best for both a Mac and PC without having to buy AirPort also?
Thanks in advance!

Whatever you do - do not by the HP8500. I am about to take a baseball bat to mine and bett the living daylights out of it. I used to have a 6500, reasonably god but slow and woudl not scan when linked to the mac...so I 'upgraded'.
Initially it worked well, quality is good and did everything well ....it still will not scan with the mac but will with every other lap top/PC in my house..but hat did not bother me too much. It is fast and quality is good...UNTIL
- It drinks ink faster than than you can imagine
- you cannot buy non hp replacement cartridges easily and not from Staples of PC World etc
- It sense that ink is running down so keeps sending annoying messages
- if you use a non std cartridge it registers it as empty and send more annoying messages
- the cartridges cost about £50 to replace al four - you can buy a new kodak all in one printer for £55
- it will print perfectly well with non HP or HP remanu cartridges, but still sends the dumb messages
- when using HP catridges it keeps telling you to replace them even though they are not empty and theres plenety of ink (marketing scam)
- This morning, the printer decided that the new (non HP magenta cartridge) that put in yesterday and was quite happy with ...is now empty...it refuse to print even black until i replace that cartridge.
I have no problem buying HP catridges if the price is fine - but the combination of a software blip plus high prices make me seethe. I will destroy this piece of junk and buy myself a Kodak or Brother - but never ever again an HP product - having spent over £3000 on PC/Laptops and printers from these bozos over the last two years they can count me out from next years forecasts

I recently bought a new iMac as well as a wireless time capsule and have it connected how can I use this external drive as the location to store all my files for iTunes, or is this even possible?

New iMac user here, I recently bought a new iMac and Time capsule and have the whole network up and running now. I have connected another external HD to the time capsule as well and have a total of 3 TB of storage connected wireless to my new iMac. My question is can I use this location as the default location for iTunes? I doubt I am gonna run out of room considering the iMac has 1 TB of storage already, but I'd prefer to keep my movies and music off the Mac to keep it running smoothly. If this is possibly, I'd like to do this with iPhoto as well.

I would advise against placing your iTunes library on a Time Capsule.
The Time Capsule is designed as a backup device and not for wireless streaming of video.
Before you do anything more, can I suggest you put into place a reliable, redundant backup strategy.
Unless you are prepared to risk loss of your iTunes library due to a hard drive failure, I would not put iTunes on the Time Capsule.
Leave your iTunes library on your iMac until such time as your internal drive is full. Backup to Time Capsule using Time Machine and create a clone of your internal iMac HD to your external drive.
That's my 2 cents worth. Others may have a different opinion.

Has anybody solved the slow wireless connections speeds of the new Imacs

I have just purchased the new imac...and was made aware of the disastrous connections speeds using wireless.. Does anybody know if apple have come up with a solution...or are they just not dealing with the problem?

I am a brand new Mac user with a new 24 inch iMac purchase. Macs are supposed to be hassle free right? Right. No question I was about ready to throw it out the window because the wireless connection to the expensive AP base station was, oh, 100x slower than my Dell laptop side by side about 1 foot away. Nothing changed even if I connected directly to the AP using an ethernet cable. My connection consists of an Actiontec DSL gateway connected directly to my AP extreme that allows wireless to my PC laptop as well as my new iMac. Hours and hours go by until I find this help link on Mac Orchard Forums:

With the new Leopard installed I went to the "portforward" link first and followed the instructions exactly to set a static IP address, then I reset my DNS servers with the exact numbers you see above - IT WORKED IMMEDIATELY!!!!! I didn't have to call my ISP or anything, it just worked exactly as it should with both Safari and Firefox. Now this Mac is flying and I will not be tossing it back to Jobs.
Good Luck!

New imac 27(Intel based,bought 2013) slow wifi connection with my Verizon fios actiontec router. All other wireless devices in the house(ipad 3gen,MacBook Air ,hp laptop) have a much faster connection. Should I change router settings to G only,etc

New imac 27(Intel based,bought 2013) slow wifi connection with my Verizon fios actiontec router. All other wireless devices in the house(ipad 3gen,MacBook Air ,hp laptop) have a much faster connection. Should I change router settings to G only,switch channel from auto to maybe 6,channel width to 20mhz? Already changed security settings to WPA2. Currently router is running in mixed b and g mode.

If you have one computer running on G they will all run on G. All ROUTERS are backward compatible, in otherwords if you have a group of computers and all of them are N compatible and one or two are G They will all work but the N computers will run at N and those that are G will run at G speed not N.
It can get confusing but really it is simple. The newest is 802.11 AC and ic used with the newest Mac Computers made available in November 2013. So if you have the newest Airport Extreme that is 802.11ac and the newest computers that are AC compliant your speed will be 5 times faster than anything on the market right now.

New iMac wireless internet crashes repeatedly -- why?

Just set up the following wireless LAN: Netgear WGT624v3 wireless router as access point between a broadband cable modem, a new 27" iMac, a PowerBook G4, and a Canon wireless printer. Everything works great except for one thing: whenever I'm trying to use the internet on the new iMac, my internet connection crashes and I have to manually reset the modem and router. This happens when downloading a file even as small as 2 Mb. As you can imagine, this has become incredibly irritating, as none of us can get anything done on our new computer without me having to come over and flip a switch on the power strip to repeatedly reset the internet connection.
The Netgear router is about as old as the PowerBook (3+ years)--I see it's listed "EOL" (end-of-life) on the Netgear website, and I'm wondering if it may not be powerful enough to handle the new iMac? That's the only thing I can think of, since using the internet with the PowerBook causes no problems at all. I don't understand the subtleties of Airport v. Airport Extreme, 802.11b, g, n or whatever, to figure this out on my own.
Anyone had a similar problem and/or can confirm that the router is the culprit before I needlessly spend money on a new one?

Some things you can try, if you haven't already:
-Make sure you don't have any cordless phone base stations operating near your router.
-Are any other electrical appliances (like microwave ovens or fluorescent bulbs) operating when your wireless connection fails?
-Power down the router and the iMac, then restart each.
-Change the channel your router uses to broadcast its signal. You should be able to do this from the web browser interface most routers support.
-Check Netgear's support website for firmware updates. Some routers can be commanded to check this from the web browser interface.

My new iMac has recently had OSX Lion installed on it and now when I start the machine it looks like its updating something every time, and the wireless doesn't work. So I restart and everything is OK - until I have to start up again the next time?

My new iMac has recently had OSX Lion installed on it and now when I start the machine it looks like its updating something every time, and the wireless doesn't work. So I restart and everything is OK - until I have to start up again the next time - then I have to repeat this again! Any help appreciated.

I've been having the same issue, but have just discovered something on my own that hasn't been pointed out in any of the forums I've visited. In what I thought would be a vain attempt to help myself, I went to System Preferences, Users & Groups, and then clicked on Login Items. I discovered that one of the Items that was listed to open automatically upon login was iTunes Helper and that there was an exclamation point beside it indicating that it was incompatible. I simply deleted that item and now I don't have the situation you described and my wireless is connected. Hope this helps!

Problems setting up my TC. Have just bought new iMac(OS 10.6.8) and TC. I tried to set it up. iMac cannot find it. I have tried direct connection with an ethernet cable to Mac or direct to my wireless router but nothing. Just a flashing orange light. Help for a simpleton please. Have tried reseting TC, but to no avail.

Just updated from 10.6.7 ---> 10.6.8 and had the same issue. Despite having done a clean install from 10.6 and got everything back off my TC, now Time Machine can't find it!
Green light is on, ethernet cable conected, network CP says its conected but nothing. Airport Utility can't find it. Hit reset button, Orange flashing light but still no show in Airport Utility.
But I know its there, as rebooting from 10.6 SL disk shows the backups are still ok?
Hmm, ideas anyone?

Migration assistant stalled ( 110 hours, after 30 hours ). How else can I transfer my data from PC to new iMac without wireless migration assistant?

i am a new mac user
i have a new imac
was trying to transfer data from old pc to imac using migration assistant ( wirelessly )
i had done it once already, but i noticed that although it took about 8 hours, very little data from the c drive was actually transferred ( i had not noticed i had to designated folders to copy )
so i did it again, targetting folders on the D drive and my external hard drive F - lots of data ( about 300 GB )
after an hour i noticed that the estimated time for completion was 88 hours ! i did let it run for about 30 hours anyway and hoped for the best ...
this morning when i woke up the time remaining was estimated at 42 hours, but then it suddenly jumped to 110 hours !!!
when i came home 8 hours later, it was still at 110 hours, so i stopped it - i assumed it had crashed ...
i got a message that one folder on my pc might have been lost - corrupted
incredibly, after more than 30 hours, no data had actually been transferred to my new mac !!!!
in any case, i see now that migration assistant created a new user account anyway, which i do not want
SO
how can i transfer data from my pc laptop to my new imac, preferrably with a direct cable connection as opposed to wireless, directly into my main account
and i how can i delete the other account migration assistant created in the initial "successful" transfer
thanks
chris

Ah yes, forget the Firewire cable then, use ethernet.

Brand new Imac and wireless is saying no hardware installed? really confused as it was working fine yesterday, brand new Imac and wireless is saying no hardware installed? really confused as it was working fine yesterday

Hi Guys, I juts bought a new Imac and jad it connected to my wireless router yesterday but now when i click on the wireless button on the top screen, it comes up saing wireless hardware not installed, have any of you had this problem? Thanks Tracey

You can quickly see if there is a problem in reporting the AirPort card by going to the apple in the upper left corner, About This Mac, More Info, System report and look at the information on Hardware and the AirPort report...make sure it is not indicating a fault.
If all looks ok, try removing the network information and reentering it and see if the AirPort responds.

Just bought a new iMac and it is telling me it will take 27 hours to transfer documents from the old one!! Is this normal? Can I speed this up some how??

I just bought a new iMac and it says it will take 27 hours to transfer documents from the old mac! Is this normal? Can I speed this up??

If you are transferring with Wi-Fi or Ethernet and you have to transfer a lot of files, it's normal. Wi-Fi and Ethernet are the slowest methods to transfer files.
Instead, you can check if your old Mac has got a FireWire 800 port. If so, you can get a Thunderbolt to FireWire adapter and a FireWire cable, so the transfer will be done by FireWire, making the migration faster.
If you don't want to spend money, continue the migration. Another thing you can do is to get an external drive, make a Time Machine backup of your old Mac and use the backup to transfer your files to the new Mac. Read > http://support.apple.com/kb/HT4889?viewlocale=en_US&locale=en_US

I have a Panasonic FZ38 HD camera. I can load and view my hd movies onto iMovie with no problems via my camera or a card reader. When I try to copy my hd videos from my old Windows pc to my new iMac, the picture speed has doubled but the sound is normal.

I have a Panasonic DMC-FZ38 HD camera and have lots of hd movie clips stored on my old Windows Pc using Photofun software supplied by Panasonic, which I want to transfer to my new Imac computer. I am able to copy my most recent movies that are still on the memory card from my camera onto Imovie and view them with no problems at all. When it comes to copying my old existing hd movies stored on my Windows Pc (and which are no longer stored on a memory card), I discover that when I view them on the Imovie, the speed has doubled but the sound is normal. In order to transfer my old movies I have copied them back onto a memory card (SDHC - the same card as previously used) and then put the card back into my camera and then copied them onto my Imac via the camera USB. I have also used a card reader but get the same result. If I view the same movie through my camera, or look at it on my old pc, it plays at normal speed. Does anyone have any ideas as to why this is happening please?

have you read and watch the Tutorials..? :
http://www.apple.com/ilife/tutorials/#imovie
iM is a bit.. iffy, when it comes to the definition, what a 'camera' is. historically, only tape based machines were a movie-camera. nowadays still-cams allow movin' images too..
but, as mentioned above: the intended workflow is: material from photo cameras (even when they move) => import via iPhoto; material from video cameras (even when they don't move.. ) => iMovie
when the import is done, you'll notice in all iLife apps the 'media browser' - in iM09, on the very right, the icon with a camera on.. click it, presto, all (incl. your 'videos') your iPhoto Library at hand for usage in iMovie.
