Time Machine 802.11n

I am considering buying a Time Capsule and use Time Machine to back up 2 iMacs (specs of both below).
However I see that Time Capsule uses 802.11n Wi-Fi and System Profiler says: Supported PHY Modes: 802.11 a/b/g'.
Hoping someone can elucidate/elaborate...?
With thanks,
Gilly

I checked my TC and in the wireless tab of Airport Utility, the radio mode can be selected. The options are 80211.n (b/g compatible), 80211n (a compatible), 80211n 2.4GHz, and 80211n 5GHz.
If you have wireless phones in the house you might want to check the freqs to avoid potential signal conflict. This shouldn't be a problem though as long as the devices potentially using the same freq use different channels. DECT 6 phone should not be a problem. Older phones might be a problem i.e. 2.4GHz phones.
After all this, actual thruput on the Internet is dependent on your ISP and the loading of the Internet. I tested on http://speedtest.net and experienced no significant changes in thruput to the same test site no matter what 80211n mode (g or n) or freq setting (2.4/5GHz) I used.

Hello, no experience with TC, but...

Can't imaging something not being covered there.

I have an 2tb time capsule 802.11n Wi-Fi base station can I use this as an external hard drive and use a new airport extreme 802.11ac Wi-Fi for my wifi?

You can use the 2 TB Time Capsule as a network drive. That means that it must connect to one of the Ethernet LAN <--> ports on the new AirPort Extreme, or connect to the network using wireless.

When I start my MacBook Air, I get a problem report on the Time Capsule 802.11n. When I click Continue, it asks for a password. I don't know what the password is because I didn't set this up. How can I find out what the password is?

Who set it up?

Apple TV and Time Capsule 802.11n -- idle timeout and group key stuff...

I've been having some wireless issues since moving to a Time Capsule to provide my 802.11n service.
I have my time capsule setup as an 802.11n only router, on a 5 ghz band only, with WPA2 security (AES-CCMP.) My reception is great -- but I've noticed in the logs that there's an idle disconnect that seems to occur about every 10 minutes.
What seems to be happening is that when the idle disconnect occurs, the AppleTV renews its connection. The problem, at least 90% of the time, is that if the "group key timeout" value in the Airport Admin Utility has been passed AND the idle timeout occurs, the unit appears to be unable to connect to the network unless you reboot OR reenter the network password.
The Time Capsule is setup strictly from a networking standpoint as a wireless bridge -- I have an existing network DHCP server, and during the disconnects, a DHCP renewal is not occurring.
Another observation when this issue is occurring: on the "Network" settings page, instead of selecting wireless network, you can select TCP/IP, and select "DHCP" and the unit will state that it has successfully connected to the network, and states the network name. The Time Capsule though doesn't show an active client; I have to assume this is some sort of bug.
Since the unit works fine after a reboot, I have to assume something isn't quite right with the way it is attempting to reconnect to grab an update group key after an idle timeout occurs.
I'd like to test this further, but I can't find anyway in the Airport Admin Utility to change the idle timeout value. There's a place to enter the group key timeout, but not the idle timeout.
Has anyone else noticed this behavior and found a way around it?

Just one more follow-up post to say that I continue to have the same problem. (Just picked up my TC and aTV on Tuesday and didn't get a chance to do too much with it until this weekend.
I have the TC running in bridge mode to my FIOS Actiontec router. The Actiontec does DHCP for the home network (has to because of paculiarities with FIOS on MOCA with a cable TV set-top box) and runs an 802.11 g network for all my non-N hardware (iPhone, older computers, etc.). The TC runs 5 GHz N-only, and the aTV connects to that. I set things up this way because I wanted to keep the aTV and my N-capable computers on a dedicated wireless channel for speed.
Alas, I'm afraid I'm going to have to use the aTV on the G network, or perhaps ethernet, until this problem gets sorted out.

Can my time capsule 802.11n (4th gen) affect performance?

for several months i have been having trouble with what i think is excessive read/writing and a slowdown creating the dreaded beachballs. i especially have trouble when safari is open.
can my time capsule cause these symptoms? about a week ago i got a message that i was not connected to the internet even though i had just been using it. i called my isp (wow) thinking they were down. the rep said that they weren't having trouble, but he was getting a week signal from my router (time capsule).
in the last few days i have been experiencing beachball delays on my laptop, which uses my home wifi. i have not had trouble with my laptop before, only my intel imac.
when i run the airport utility, it tells me that my time capsule is ok.
is it possible that a failing time capsule is causing my problems? i bought the time capsule in early 2012.
here is my etrecheck report, if this helps.

thank you for your help.

i'm writing to report. i downloaded the java update that a brody suggested. i ran fix disk permissions and then tried the internet. i started out using firefox and then chrome. they were nimble and responsive (sounds like a car review). then i tried safari. it was slowwwwwwwwwwww. no beachballs, now gray revolving circles. safari is /was so slow it often takes a while for a character i have typed to show up on the screen.
i have rerun etrecheck and the outdated javaapplet plugin message is still there as though i have not updated my imac.
i am going to remove some of the 3rd party software, but i'd like to be sure that i have accomplished what i needed to do re java.
does anyone have any other ideas about safari besides using another browser?
thank you.

Time capsule 802.11n

I bought my time capsule a few weeks ago, it´s working fine. My question is what happens if I erase a file from my computer and a new back up is made in time capsule, will the file that was store in the previos back up also be areased?

that's the whole point of time machine, you can go back in time and hunt around your system to find a file deleted.
The best thing you could do to prove this is to do a backup, delete a file, do a backup again, then go back in time and find the file again... To prove this, I've just gone back to JUNE to find a file I deleted a while ago!

Time Capsule 802.11n WiFi Hard Drive 1TB

Does this act as a Wireless Router as well?

Which wireless router will perform better XFINITY or my Time Capsule?
It is impossible to answer without a full breakdown of the network and what you do with it.
It may not even be possible if the XFINITY wireless is not bridgeable.
And there is usually no real need to choose. If your modem router is supplied keep using it as router.
Plug the TC in by ethernet and run it in bridge mode (that is router bridge). But you can still use the wireless on the TC. Simply set it up the way you want and make sure the two do not interfere with each other.. you can do this by locking radio channels. You can use identical SSID (wireless name) and security on both and the clients will join to the strongest signal. But it is better to use this setup with the two separated by a few meters at least if not in different rooms.

Replacing an airport express 802.11g with an airport express 802.11n

Hi there,
I'm about to replace my airport express base 802.11g with a new airport express base 802.11n.
Is it difficult? Is there a guided procedure? Is there something that I should ABSOLUTELY NOT do (or ABSOLUTELY DO) before, during and/or after the replacement?
My home network is made up by MB 13'', MBP 15'' (both with Intel processor and Leopard) and a Time Machine 802.11n 500Gb.
Thank you in advance.

will the express be your main wireless router or the time capsule ?

usually not. see the setup guide

Setting up Time Capsule with existing AirPort Extreme 802.11n and AirPort Express.

I already have and am using an AirPort Extreme 802.11n with an AirPort Express. I want to set up a Time Capsule 802.11n. Which is the best way to configure this?

... Which is the best way to configure this?
The answer depends on what you need the TC to accomplish. If all you need it to do is perform Time Machine backups, simply have it join your existing network in client mode. It would be if it were to connect to your existing router (presumably your Extreme), not through an "extended" wireless network (presumably your Express).
If you need the TC to "extend" your network so as to serve additional wireless clients, you can do that also. Configure it to "extend" the network created by your Extreme.
As you can see it's quite versatile.

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 !
Rutger

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

Sharing Time Machine Back Up with Desktop and MacBook

Hello,
In preparation for my work on the road I back up my desktop using Time Machine on my Time Capsule, wipe my MacBook clean and Migrate my files to the MacBook so I can take everything. In recent years I notice when syncing my devices, that process has improved and the iPhone,iPad recognises the MacBook as basically the same as my desktop and I don't have to wipe and sync the device. Thank you Apple engineers for that improvement.
This year is a bit different. I have done the migration, but am delayed departing. I would like to share my Time Machine back up across the two computers. Sort of a poor mans macbook sync. I would treat the Macbook as disposable and the Desktop as primary. Make changes to the iMac then update the MacBook before I leave.
Can I use my desktop , back it up to Time Machine, then update the macbook as required? I would do this until I leave.
Also I noticed for the first time the MacBook is running a different OS to the iMac. Will this matter to me?
Thanks,
Ken
Desktop is an iMac 24 running MacOS10.6.8, 2.4 GHz C2D
MacBook is an early 2008 running MacOS 10.6.3, 2.4 GHz C2D
Time Capsule 802.11n, 1st Generation, version 7.6.4
iPhone 3GS iOS 6.1.6
iPad 2 , iOS 7.1.2

So, the macbook today, I did get this message from the OS re TimeMachine
"Would you like to reuse the backup "/Volume/....sparsebundle"
The backup was created on a different computer. If you reuse this backup it can no longer be used by the original computer.
I selected Reuse Backup. This is very convenient. I am wondering now.
How do I select back and forth on the computer to reuse the various back ups?

Time Capsule/Time Machine Help

My Time Capsule is set up to run my wireless network, and is also shown as the external drive to house my Time Machine backups. But, it appears that no Time Machine backups are making it to the Time Capsule, and are instead all saved locally. All of the Time Machine backups are listed in White/Grey (no purple datapoints to be seen). I've re-set up the Time Capsule as the drive for Time Machine backups, but nothing changes. I have to do a full backup of my hard drive tonight because my hard drive has to be replaced this weekend. Any ideas? Appreciate the help.

Time Capsule 802.11n (3rd Gen), Mac OS X (10.6.8)
Are these still true?
I would guess you are on Mountain Lion at the very least.
Are the backups over wireless?
Plug the TC directly into the computer by ethenret.. do a full reset and minimal setup.. TC should be in router mode.. This will not delete or harm the backups in any way.
Do a full reset of TM.. See A4
http://pondini.org/TM/Troubleshooting.html
This could be vital to getting a working TM backuip.
Then restart TM and point it again to the TC.
If a hard disk has to be replaced I would also do a disk image. Do trust just TM.
You can do a disk image from disk utilty but superduper even free download version can do it.. !!

Help Help..Can not back up my Macbook Pro with Time Machine

I have Mac Book Pro Mac OS X version 10.6.8 and Time capsule 802.11n (3rd generation), I used to do back up wirelessly but then it stopped. so i connected it directly to laptop, it did not work. so i did reset on Time Capsule/Machine and didnt work. Show error 1) Time Machine could not comple Back Up (The back disk image "/volume/data/macintosh.sparsebundle"could not be created (error 1) and then different time i tried got different error 2) Time Machine Could Not Complete (the back disk image "/volume/data/macintosh.sparsebundle"couldnot be created (error 60)..please advise

The TC drive is network and will never show up in disk utility.
You can mount the sparse bundle into the utility and do a check on it.. but that serves little purpose.
I used to do back up wirelessly but then it stopped. so i connected it directly to laptop,
It is highly likely the setup is wrong.
Please do a full factory reset of the TC.
The Factory Reset TC Gen1-4. Or AE Gen1-5
Unplug your TC/AE. Hold in reset. and power the TC/AE back on.. all without releasing reset and keep holding in for about 10sec.
Release it when the status light flashes rapidly. If it doesn’t flash rapidly you have missed it and try again.
Be Gentle! Feel the switch click on. It has a positive feel.. add no more pressure after that.
TC/AE will reboot after a couple of minutes with default factory settings and will wipe out previous configurations.
No files are deleted on the hard disk.. No reset of the TC deletes files.. to do that you use erase from the airport utility.
Redo the setup using the airport utility. For older OS and TC you can do this by ethernet with wireless turned off if you like.
Tell us the main modem router and how the TC was originally setup.. if it was in bridge mode.. then put the TC back in bridge and plug it into the router.
If there are issues they will show up in the airport utility. Please list any issues it has.

Help needed with "Time Machine could not complete the backup" because it is too large

I'm receiving "Time Machine could not complete the backup" because it is too large for the backup disk. I have a 500 GB Time Capsule 802.11n (2nd Gen) and a MacBook Pro running on 10.6.8. I just replaced my laptop's original hard drive with a new 1 TB and restored that with what was on my Time Capsule. Now, I have no backups on my Time Capsule prior to the new hard drive. When I click get info on my hard drive, it states only 296 GB of the 1 TB is used. However, the Time Machine error message states that the backup requires 315 GB but only 221 GB are available. It has deleted all of my old backups, so I would think my Time Capsule should have plenty of room to backup the 296 GB on my computer. Is my old backup from my prior hard drive stuck on the Time Capsule and instead of Time Machine trying to just update those files, it is preserving the old hard drive backup separately and trying to make a new backup of my new hard drive using the remaining space? If so, how do I fix this? Any advice greatly appreciated.
