Slow data transfer with Time Capsule on 802.11n ?

Hi,
Actually, I don't know where to start. But let's explain my setup first:
My iMac (wired) and AppleTV (wireless) are connected to the Time Capsule (802.11n, 5Ghz)
My girlfriend's MacBook and 2 x iPhone 2G's (wireless) are connected to an Airport Extreme Base station (802.11b/g compatible).
The Time Capsule and AEBS are connected and show two different networks.
Now the problem:
When I copy files from e.g. the iMac to the MacBook or to the Apple TV, it's very slow. I've used scp to copy a 200 mb file and it took about 1.20 minutes (at 2.5MB/s). I've did the same when the iMac was connected over wireless and it took about 3.45 to 4.30 minutes (at 1.0MB/s).
I'm not sure if this IS slow, but it certainly feels like it. 802.11n should be around 100 Mb/s in practice and 802.11b/g around 20-25 Mb/s.
By the way: downloading from the Internet is excellent, I get the full download/upload speed my provider offers for my subscription.
Second, I added the signal strength/noise levels for the Time Capsule attached devices. They vary around -68Db signal, -90Db noise.
The question is: are these levels normal ? What should be higher or lower ?
Thanks in advance !

The new Airport Extremes and Time Capsules suffers from terrible performance over the 5GHz band and it's a problem that not only affects me and you, but hundreds of thousands of other owners.
Nobody knows if it's a firmware problem or the Marvell chips inside that's the problem, and Apple hasn't said or done anything for months.
I'm still hoping for a firmware update to solve this, but if it doesn't get fixed soon enough, I'm gonna return it and go back to backing up to wired disk and my rock solid Airport Express.
Not the happiest answer, but at least you have a clue now.
Cheers,
Koski

Can't connect to Time Capsule + no 802.11n support

I just got my new 13" MacBook (late 2008). Originally, I thought I couldn't connect to my wireless N router which happens to be Apple Time Machine. According to network utility program, my MacBook only supports a/b/g - this is not right! Now, I discover that in addition to the N problem I can't even connect to my Time Capsule wirelessly! Good thing I have 2 separate wireless routers (linksys).
My other Macs (white MacBook and 20" iMac) have no problem connecting to Time Capsule over 802.11n. Both machine indicates 802.11n support under network utility program.
Compound this problem with stuck 'a' key on my keyboard.
I really, don't get this problem. I spent an hour with Apple tech with no avail. I am thinking about returning this new MacBook.

I have the exact same problem you have described. Unable to find a solution. Odd because I have a 2007 MacBook Pro and it works fine wirelessly. Wireless-N on the MacBook works fine and it can connect to other wireless networks, just not it's home one.
If anybody is interested, here's a dump from the console log when airport attempts to connect. Our wireless station doesn't broadcast.

Data transfer from Time Capsule to new Mac

I have a MBP which up until 7 days ago had Mountain Lion on it. The week before that, i had major abdominal surgery and when i was in the hospital, i accidentally knocked a bottle of water over and it fried my MBP. I would not turn on after that.
I took the MBP to the Apple Store for it to be repaired, at a cost of about $800. Meanwhile, i bought a new MBP. Both computers are the same with 2.5Ghz intel processor Core i5. As far as i know, the only difference is that the newer one has a 500GB HD and the older one has a 1 TB HD, and the older one ran Mountain Lion while the new one came with Mavericks.
I had the older computer backed up on a Time Capsule. When i got the newer one, i turned it on and went through the set up process. When asked at the beginning if i wanted to transfer stuff over from another computer or drive, i said 'ask me later' or something like that. I have never used Migration Assistant before and did not understand it well enough to use it.
I transferred the backed up data on Time Capsule to the new computer wirelessly. It worked fine. When i got done,
the hard drive looked like the old one, same set, same files on the desk top, dock arranged the same way, same Safari bookmarks, and also, the same third party
programs and data, with one exception, but for the most part it was the same.
Since i set up the new computer, it has been having regular back ups onto Time Capsule.
Now, i have the older computer back, repaired. The older computer no longer has Mountain Lion. It has Mavericks OS 10.8.5. The newer computer has OS 10.9.3.
I want to do the same thing i did a week ago in order to transfer the data to the older now repaired computer, but i can't remember what i did, i'd never transferred data from Time Capsule before. I have not been in the best shape mentally, having been cut open with a 10 inch incision and pain pills.
All i know is that whatever i did, it was very easy, i believe i used Time Machine to do it, and it transferred my third party programs with their data. It did NOT involve using Migration Assistant.
I don't plan on using the newer computer. i plan to go back to using the older one which has the larger hard drive.
Both computers have the same user account names and login info. I just want to replace what is currently on the older freshly repaired MBP with what is on the Time Capsule.
I am not sure if my question is very clear but i'm wondering if anyone can tell me how i can transfer the data from my Time Capsule to my older now repaired MBP without using Migration Assistant (which i think would not transfer my 3rd party stuff). i just want to do what i did a week ago but can't remember what i did. I think i used Time Machine, i connected the computer and Time Capsule (or they were already connected wirelessly).
I did NOT choose Enter Time Machine. I think i went in to Time Machine Preferences and clicked on 'Select Disk.' I think i selected a disk that has the name of my Airport connection and has the word Data on it. Does that sound possible?
Does anyone know what i'm talking about from experience or other knowledge? because i'm inexperienced with this process and am not very clear about what happened, but i know it didn't involve Migration Assistant and it didn't involve Time Machine > Enter Time Machine, because i have never seen those before today.
Whatever i did, it was so easy, just click on the disk i wanted to transfer data from and click some button that meant "ok" or "connect" or "transfer." And then, just wait, and after some time, my computer was set up reflecting the back up from Time Capsule, including third party stuff.
Thanks for any help with this.
btw, in Time Machine now, under Select Disk > Back up disks, there are two boxes. The first box says Backup Disks, and in that box is the name of my Airport connection, i.e. the Time Capsule i guess, and on the icon, it says Data. In the second box, it says Available Disks, and in that box, it has an icon of a disk with the name of my Airport or Time Capsule and it has an icon of a Wifi symbol which has the name, Other Time Capsule. Apparently that is an option to set up another Time Capsule not listed. I wonder if i chose one of those icons and clicked "Use Disk", would that data be transferred to my now repaired computer?

(Sorry, after i posted this, i discovered it posted it in the wrong product forum, i guess when i typed in what i was interested in, it just took me to the Snow Leopard forum. i don't see a way to delete my post. Maybe the answer will be the same?)

Slow USB transfer to Time Capsule

I recently purchased a Time Capsule and have decided in addition to its Time Machine back-up duties to use it to store my iTunes Media, which I had previously had on an external USB HDD (and then use the external USB to back-up Media drive through a folder-syncing app, since Time Machine won't recognise a networked drive). I've connected the USB drive to the TC, and attempted to drag and drop the iTunes Media folder from the external USB to to TC HD.
The estimated time for completion was 7 days for 300GB of data.
Any suggestions as to what is going wrong? Please tell me that the TC isn't sending the data over wireless from the USB disk to my MacBook Pro in order to then send it back over wireless to the TC to write it to that disk! So far the TC isn't looking like a great investment - Time Machine takes so long to back up (spending 10 - 15 minutes preparing the backup and then another 10-15 minutes to write 20 - 30MB of data) that I've turned it off, because the process makes watching my iTunes content jerky. And with this data transfer problem, I'm almost ready to give up.
I'm working with a 2TB Time Capsule, 15" ealry 2011 MacBook Pro (8GB RAM, 250GB SSD), OS X Lion and a 1TB USB HDD

Please tell me that the TC isn't sending the data over wireless from the USB disk to my MacBook Pro in order to then send it back over wireless to the TC to write it to that disk!
Exactly what is happening.. sorry about that chief!! (Maxwell Smart voice).
Unfortunately if you have the external drive connected to the TC and want to write the data to the TC that is what happens.. there is no way it can directly copy since the copy is running from the laptop.
Much better to plug the external drive straight into the laptop.. and plug the laptop into the TC by ethernet cable and do the copy in one shot.. then you can do other backups (your normal incremental time machine) by wireless.
Alway try and eliminate double hop wireless.. it is incredibly slow due to having single channel half duplex operation.
Even if you have to use a separate device to do it.. the speed will be much better.
And it is better to use a usb plugged into the TC just as a backup of the TC.. use the TC itself to store your itunes rather than a drive hanging off it.

Painfully slow wireless connection with Time Capsule

I have recently bought and changed over my home wireless to a Time Capsule 2TB, which I wanted for both the backup and the ease in home networking. I have set up the wireless network and since day one it has been painfully slow! I have created two wireless networks, one for 2.4GHz and the other for 5GHz. I have been reading all over the web and boards but to no avail. Any suggestions? I am about to give up on the time capsule completely! I couldn't even download my podcast tonight.
Help!

Firstly plug in directly by ethernet to be sure there isn't a network issue on wan side.
Are you testing on multiple computers .. Mac and/or PC?? Which ones. and what network cards are being used?
Try and remove anything that uses G wireless and throw away any B wireless. It will not work together with N even if it is an option.
Turn off the guest network if you have it on.
Have you used a wireless analyser like kismac or inssider for pc? Find the free channels and set the wireless to that. Use no security at first to test.. briefly.. and then select wpa2 personal. Is there any difference?
Do you have another wireless router running?? Were you using a different wireless router for comparison?

Super slow internet connection with time capsule.

Time Capsule wireless internate speed is insanely slow its super anoying, i have 15mb from comcast, and speedtest its scoring under 3.5mb down and 0.06mb up with a ping of 1025ms yees 1025ms this is unacceptable its almost impossible to use the internet please i need some help.

How can I get my time capsule to work like it used to?
Your TC is too old.. the power supply is on the edge of dying. The hard disk is probably also on its last legs..
The wireless card itself might be nearing EOL.. it is now 4years old.. or a bit more.. most stuff now is really not made to last more than 3years.. and the early TC tended to die in droves at 2years.
If you are prepared for some DIY.. you can fix it.
https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem s/apple-time-capsule-repair/repair-type3
I have several suggestions. At various prices and difficulty.
I would replace the hard drive.. it is out of warranty and has run in a super hot environment that is outside its spec.. and still it refused to die.. at the very least run a full pass erase from the disk utility, and see if error come up or the drive is slow. It might be weak read areas of the drive.
Frankly .. unless you like the challenge, it is simply time for a new one.

Extremely inconsistent data speeds with Time Capsule

If I set my Time Capsule to N band 5.0 GHz I get around 90 megs down consistently (my service is rated up to 100 megs down). However I need to set it to 2.4 GHz so that my iPhone 4S can use the Wifi as well. With this setting speeds on my iMac and Macbook will vary anywhere between 60 megs down to 2 megs down within minutes of each other. It's completely inconsistent when set on 2.4 GHz, but rock solid when set on 5.0 GHz. Is my wireless card possible failing? Thanks.

With this setting speeds on my iMac and Macbook will vary anywhere between 60 megs down to 2 megs down within minutes of each other.
This is a classic sign of wireless interference.
There is much more interference on the 2.4 GHz band from cordless phones, other wireless systems, wireless security systems and cameras, BlueTooth devices, satellite receivers and who knows what else.
For example, my neighbor's cordless phone...across the street...can really slow down my wireless network if my neighbor is in his front yard talking on the phone. The network speeds back up as soon as he goes back into his house.
Check this Apple Support Document for more details and some suggestions:
http://support.apple.com/kb/HT1365
If your wireless card were failing, it would likely be acting up on 5 GHz as well.

Automatic pc Data Store with Time capsule possible?

I warnt to Bus a Time capsule and want in Addition To my Mac Data Storage automatically Safe the Data from a PCS. Is this possible? How?

Sorry but your question is a little hard to follow.. do you want to backup a PC..
The TC is not now or ever a data store.. you should not use a TC as a file server without serious consideration to the total lack of backups. TC cannot back itself up.. nor can any software you have backup network drives unless you purchase one.
A backup software can certainly backup a PC to the TC.
You need to buy it though.
Genie Time Line Pro is often recommended.

Slow internet connection with time capsule

The only way to have the real speed is in bridge mode, do anyone has a solution?

Hi all,
first of all please forgive my English but I'm sure you'll understand the below.
I bought a time capsule 3T recently and after 2-3 weeks I faced the same above problems with internet speed.
Everything was perfect in the beginning but twoo weeks later I couldn't browse the youtube site so imagine to watch a video.
The setup is:
ISDN modem>speedtouch adsl router> via ethernet timecapsule-bridge mode.
To the home network of timecapsule are connected one imac one macbook pro.
Since there were two wireless networks, the speedtouch and time capsule,
I decided to choose the speedtouch network for iphone and ipad.
After the problem with internet speed appeared for the imac and macbook,
I checked the connection through ipad and iphone and was perfect and very fast.
I was confused and I read all threads about the same problem.
So I decided to join the speedtouch network for imac too and to change network-to timecapsule-
whenever I need to backup to the timecapsule.
I was surprised to see that imac connected to timecapsule, without have joined its network
and also it was possible to enter timemachine without changing the already joined network
of speedtouch router.
I think that the connection is possible because timecapsule is connected via ethernet cable to the
speedtouch so the connection is something like "dublex" or "bidirectional" (I don't know how to write it)
Now the problem has been fixed, timemachine works perfect and the internet speed is fast
as before.
I hope this helps and let us know if will work for you.
cheers,

Does the latest Time Capsule broadcast 802.11n better than original?

I'm in a 1700 sq ft house with my original 500 GB Time Capsule upstairs and a MacBook Pro unibody downstairs in the living room. With 802.11n only or 802.11n/g/b enabled on the TC, the MacBook Pro can't detect a network.
Would a new Time Capsule broadcast the 802.11n significantly better than the original in this situation?

Bob Timmons wrote:
The newer version of the Time Capsule has an "improved" antenna design that may help things a bit. But, if you have no signal now, I very much doubt that a new Time Capsule would provide you with a usable signal in your situation, given the information in your post.
Have you verified that the MacBook Pro is working correctly? Can you get a good signal when it is close to the Time Capsule?
Yes.
If things check out when the MacBook is close to the Time Capsule, then this would indicate that you have too many obstructions...walls, ceilings, etc. between the Time Capsule and the MacBook when it is downstairs.
Yes, if I set the TC to 802.11n/b/g or 802.11n only, the MacBook Pro won't see the network. If I set the TC to 802.11g only, it shows full signal strength. This isn't surprising to me, as I have an older Airport Express whose signal also could be easily picked up downstairs.
Is there such a difference in range between 802.11n and 802.11g?
You may want to consider an AirPort Express to position it at an approximate mid-point between the Time Capsule and downstairs so that it can "extend" the wireless signal downstairs.
To get an idea if this might work, move your MacBook to a position that is 1/2 to 2/3 of the distance from the Time Capsule to the downstairs area where you want to use the MacBook. If you can get a good signal on the MacBook at that point, this means that an AirPort Express should receive a good signal as well so that it can "extend" the wireless network.
It's never possible to predict performance in advance, so if you want to try the AirPort Express, it would be a good idea to know the store's return policy in case things don't work as well as hoped.
Thanks.

How do i know if time capsule is 802.11n?

how can i check if airport express is 802.11 g or n?

Every Time Capsule that has ever been produced is 802.11n capable

Time Capsule & Vista - 802.11n drivers?

I've set-up the TC to use the wireless-n only on the 5ghz spectrum. Everything is running fine under the Mac OS -- but booting Vista in the boot camp partition and using the wireless-n network is very slow and the signal is very weak.
Do I need load new Vista drivers, or reload the Broadcom drivers from the Mac OS disk in Vista? Any help is appreciated.

I've run into this same issue with a new MacBook Pro. The wifi drivers on my Leopard install disc don't work in Vista on this new machine, so I'm stuck without wifi for now.
From what I've seen so far, we might have to just wait for Apple to release a Boot Camp update to create new drivers for these machines. In the past, this typically means burning a new CD of drivers with the Boot Camp utility in Mac OS X (or dumping them onto a USB drive), then switching over to Windows and installing.
Vista tells me the actual manufacturer of the 802.11n hardware, so I'll try checking their site later this weekend to see if they have a newer driver version themselves that could work.

MacBook Air and problems with Time Capsule in 5GHz Radio Mode

We have our Time Capsule configured to 802.11n only (5 GHz). We've done this to work more efficiently in a particularly noisy wireless area. The problem is that the MacBook Air can't maintain a connection to it and when it loses the connection, the wireless interface seems to disappear from the Mac altogether - the wireless status indicator just shows an empty cone. The only solution is a restart. Sometimes it loses the connection after a couple of hours, sometimes within minutes, though it always goes eventually. All other machines on the network are fine, and switching the Time Capsule to 802.11n only (2.4 GHz) solves the problem, though there's a lot of noise at that frequency and our network performance as a whole suffers.
I know there's similar threads around dealing with the MBA and wireless issues (I've tried all the solutions vaguely related, e.g. deleting and recreating the wireless interface), though none that deal with this specific problem, which I'm convinced is caused by the radio mode of the Time Capsule.
All software / firmware is the latest:
MacBook Air 10.5.2 Wireless Card Firmware Veriosn Broadcom BCM43xx 1.0 (4.170.46.5)
Time Capsule Version 7.3.1
I was hoping the recent firmware updates would sort this... any one else running a Time Capsule in 5GHz mode with a MacBook Air?

I'm running my TC in 5ghz mode with my MBA. My original problem was the lack of signal strength coming from my AEBS caused the MBA to have a slow connection. There are a number of pipes in the wall that separates the two rooms where my MBA lives and the AEBS is.
So, I hard wired the TC to the AEBS and placed the TC in the room where my MBA lives most of the time. Now that the signal strength is really good I'm not having any issues.

Troubling extending wireless network with Time Capsule and Airport Extreme

I am trying to set up and extend a wireless network in my house, but it’s not working right. I have two Airport/Capsule units in the house:
2TB Time Capsule (Dual-Band II)
1 Airport Extreme (Dual Band)
I have the Verizon Fios router as my gateway to the internet, and also as my DHCP server. I have also tested the ethernet ports in my house to verify that they work, and that I can get a DHCP-issued IP address.
Now, my Verizon router has WiFI, and it’s still on. I am not using it though except to troubleshoot. So far as I understand, this should not cause a problem.
Base station setup
So I setup the TC to Create A New Wireless Network, on the ethernet network it’s on (Dlink switch plugged into Verizon router). I set it up in Bridge Mode (as opposed to having it dole out IPs, since the Verizon router does this already). The TC gets a valid IP, and my wireless device connect to it without a problem. I have checked “Allow this network to be expanded” under Wireless settings.
Extended station setup
The AE Dual-Band is plugged into the Ethernet, and is reset to Factory Settings. I name it “Airport Extreme 2” and I chose “I want Airport Extreme to join my current network.” The other two options are: “I want to create a new wireless network” and “I want to replace and existing base station or wireless router with Airport Extreme.”
I chose to “join,” I select “I want to connect Airport Extreme to my network using Ethernet to extend my existing wireless network.” The other options are to disable wireless entirely, or to “wirelessly join my current network.” On the next page it asks me to select the device or network that the Airport Extreme will connect to using the Ethernet. I set it to the Time Capsule.
Results:
Access near the Airport Extreme 2 is incredibly slow. Speedtest shows I am getting less than 1Mbps. Worse yet, my mail client won’t connect. It just times out.
What I had hoped was that the AE would connect via Ethernet to the network, and just bring the wireless network to the other side of the house. Instead it almost seems as though it is just re-amplifying the TC’s signal. Otherwise, why is performance so bad?
Thanks to anyone with some insight here!

Hello Kennuff. Welcome to the Apple Discussions!
Since you have the ability to connect all of the routers by Ethernet, there is no need to configure the Time Capsule (TC) & 802.11n AirPort Extreme Base Station (AEBSn) for a dynamic WDS (aka, extending a network). This option is only when the routers do NOT have an Ethernet connection between them.
Instead, you want to configure the TC & AEBSn in a "roaming" network. I suggest starting by performing either a "hard" or "factory default" reset on both.
Next be sure that both the TC & AEBSn are on the same Ethernet subnet coming from the Verizon-supplied router.
Configure the TC & AEBSn as follows:
AirPort Utility > Select the TC or AEBSn > Manual Setup > AirPort > Wireless
o Wireless Mode = Create a wireless network
o Allow this network to be extended: <not checked>
o Radio Mode: <leave the default or if you require a specific mode make sure both routers are configured the same>
o Wireless Security: <configure both routers the same>
AirPort Utility > Select the TC or AEBSn > Manual Setup > Internet > Internet Connection
o Connection Sharing = Off (Bridge Mode)

Using Airport Extreme as Bridge with Time Capsule

I recently replaced an Airport Extreme with a Time Capsule, which has been great. However, I would like to use the Airport Extreme in bridge mode to extend the range of my wireless network. I don't want to use WDS, so I've connected the two via ethernet. So, the setup is this:
Cable modem connected to Time Capsule WAN Port
Time Capsule creating 802.11N (b/g compatible) network
Airport Extreme connected to one of the Time Capsule's LAN ports
However, the Airport Extreme doesn't have an option for "Extend a wireless network" under Wireless Mode - it just has "Create a wireless network" and "Participate in a WDS network".
My goal is to have the Airport Extreme essentially acting as a remote antenna for the network being created by the Time Capsule. Is this not possible? Is it because of the difference in wireless speed (N vs. G)?

However, the Airport Extreme doesn't have an option for "Extend a wireless network" under Wireless Mode - it just has "Create a wireless network" and "Participate in a WDS network".
The "extend" option is only applicable to 802.11n capable devices. However this doesn't matter since the "extend" option and WDS are both used for wirelessly extending a network. Since you are not doing that, you will not use either of those.
You should configure the AirPort Extreme base station (AEBS) to create a wireless network. You would configure the AEBS to use the same SSID (Network name) as the Time Capsule as well as the same wireless encryption type/level/password. To reduce interference, you would configure the AEBS to use a channel as far from the one used by the Time Capsule as possible.
