Time Capsule airport slow with Intel 801.11n, fast on 801.11b/g

I've been running into this problem since I got my Time Capsule (Jan 09).
Both the Intel Macs (MacBook white old model and Imac Jan 09) have very low (50kbps) network connections over Airport. When connected with a cable speed is normal (2Mbps).
An old iBookG4 has no problem either when connected over Airport (also 2Mbps).
I've tried a fresh install of Leopard (problem was there before Leopard) but even a clean PC has the same problem.
1) Is it possible to turn off the 801.11n on a Time Capsule?
2) Any1 know what possibly to do about this?
I've tried:
- Deleting /library/preferences/system configuration
- adding open DNS
- deleting keys to airport in key manager
- reinstalling computer
- creating network locations (other than Automatic)
- Cleaning and resetting Safari
- Making sure there's a computer name in SystemPrefs/Sharing
- Turning off IPv6
In other words, I'm at a loss.
Please help.
Thanks!

Hi William,
Thanks.
Well this morning I thought I'd try something else.
I reconnected my old Base Station (the UFO model) and tried to connect to that (letting it run a separate network from the TC). And presto! Internet speed normal (2Mbps).
So I now integrated my old Base station into my WDS network, turned the wireless on the TC off (I know weird) and now everything works just fine (except of course the 802.11n).
I very much think this is a software problem as my notebook works fine on other networks, works fine on cable, my iMac (2009 model) has the same problems, but all the older Macs (old iMacG5 and iBookG4) have no problems. So something is wrong with the 802.11n. It seems to me that the chances that the TC and my MacBook AND my iMac all have hardware problems are really small, so I guess it has to do with software.
Perhaps the combination of 4 different Macs, an iPhone (2G) and two Windows PC on the same network causes a very special problem.
Cheers!
Marco

Time Capsule too slow with PLC

Hello.
Currently I have a wifi modem router (802.11g) Zyxel whose ports ethernet (10/100) have connected the following:
- Port 1 mac pro
- Port 2 NAS 2TB Raid 5 where have all the movies in HD (720p and 1080p), home videos, music, photos, etc..
- Port 3 PLC adapter Devolo dlan 200 AV http://www.devolo.com/consumer/7dlan-200-aveasy_starter-kit_product-presentation1.html?l=en
All this is in my home office.
In the bedroom of my oldest son, I have a PLC adapter which connects your PC and / or console. Also use a macbook by wifi.
In the room of my youngest son, another PLC adapter which connects your MacMini and / or console.
In the lounge have another PLC adapter that is connected to a multimedia disc DVICO TVIX M6500 http://www.tvix.co.kr/ENG/products/HDM6500.aspx
This disc I have configured to connect to the NAS and can see all the content (especially HD movies) smoothly cuts or breaks in the image and sound.
Now I buy a Time Capsule 1TB. Following instructions, I connected a Zyxel modem port to the WAN input of TC (I canceled the Zyxel wifi).
I connected to port 1 of the TC the mac pro, the NAS to port 2 and to port 3 the PLC adapter, but I have a problem set transfer rate:
From the lounge, when I connect the disk media and I want to watch any movie (even in PAL) to play me jumping on the image and sound. It is as if the ports were only a 10mb ethernet. They lack the data transfer rate (I tested on all three)
Interestingly, the TC wifi (802.11n) works properly and the macbook can see all the movies in HD without problems of jumps in the image (which with Zyxel wifi was impossible)
I've been looking in all possible configurations and find nothing.
The network works because I see all the computers, but is very slow.
Theoretically, the PLC adapter is transparent in an ethernet network and does not influence the rate of data transfer.
It is as if they were incompatible the TC Gigabit ports with the PLC adapter.
Any idea?
Greetings

Yes, that's what I meant, sorry.
and my internet connection is unstable reqularly disconnecting...
That may be the main problem. Time Machine may be just an innocent victim.
A easy way to tell is to just disconnect from the Internet for a while, and see if the backups improve, via Ethernet. If not, be sure it's not still using WIFI -- turn WIFI off to force it to use Ethernet.
If it does improve, that would implicate something in your setup or connection to your DSL modem. That's out of my area of expertise, but there are some networking gurus here who can help.
If it doesn't improve greatly, see the green box in #D2 of Time Machine - Troubleshooting. Something there should fix it.

Time Capsule Airport Connection with Deutsche Telekom 300HS VDSL Modem

I just swithched my Deutsche Telekom connection to VDSL 50 but can no longer connect to the internet. There are a couple of configurations I have tried:
a.    The Speedport 300 HS modem connected directly to the Time Capsule.
b.    As above, but with the Speedport W700V router in between the modem and Time Capsule.
The green light on the modem is illuminated to confirm the VDSL is available.
Could somebody please advise the correct settings in the Airport Utility to make either configuration above work?
Thanks,
Paul

This is the easiest one.. just use TC in bridge. You go to the airport utility, manual setup, select internet tab and under connection sharing.. off bridge mode.
a.    The Speedport 300 HS modem connected directly to the Time Capsule.
This is harder as it depends on the authentication system used by your VDSL..
The TC has limited options.. either DHCP.. so the vdsl has to pass the public IP as in half bridge type system.. or it has to be PPPoE authentication.. as that is the only other alternative offered.

Time capsule painfully slow wifi

New time capsule , painfully slow wifi , cisco works lightning fast so the issue is with the TC. Looked at forums and I see it's a common isssue. Any ideas that actually work?

Download the free iStumbler app to examine the strength of your connection.
If it's not good, look for interference with another wireless device, cordless phone, microwave oven, etc. Turn them off temporarily; if you find an offender, move it farther away. See AirPort and Bluetooth: Potential sources of wireless interference for more.
Try different WIFI channels.

Time Capsule/Airport is very slow...

Just bought a new 1TB Time Capsule. I replaced my old G router, set it all up in Airport Utility and Time Machine. My network consists of two MacBook Pros, a silver-door G4, and an Apple TV. I'm using the WPA Personal security - the one that requires 13 characters. I'm having two problems...
1) The performance of my network seems significantly slower than it was with my old Linksys router. Web pages access seems slower, and now a movie that should take only 30-40 minutes to download into Apple TV is now going to take 5 hours?
2) Because I'm going to back up three computers, I decided to only set one to do it's first big backup at a time. I set it (the G4) to start a backup when I went to bed, and when I got up only 3 gigs had been backed up.
Although I wasn't expecting lightning, I did expect the performance between the Time Capsule and the MacBook Pros to be faster. And is the backup really supposed to be that slow? I could be waiting over a week or more to get my first computer totally backed up. Am I missing something?
Bill

Forgive the size of the post, but the suggestions below have helped others with similar issues. Try each topic individually and see if things improve, If not move on to the next one.
*Keep the Time Capsule Cool*
Some posters have observed that when they positioned the Time Capsule for better ventilation and cooling, their network connectivity issues resolved themselves. Also avoid locating the devise within poorly ventilated cabinets or piling items around or on top of it.
*Time Capsule Orientation*
While the location you chose to setup your Time Capsule may be acceptable, but the direction it is oriented can have an effect on signal strength. It appears that the signal of the Time Capsule does not radiate equally from all sides of the devise.
The antennas within the devise are positioned along the 3 smooth sides. That is, there is no antenna on the side bearing the ports and cables. As a result, position the devise with the ports and cables AWAY from the direction of most of the clients that will be connecting to it.
*Cordless Phones*
Some users have discovered that the cordless phones they have in the home occupy or are near the same bandwidth as their wireless network (2.4Ghz or 5Ghz). Try temporarily disabling the handsets and their bases and see if network connectivity improves. If so you may need to change the channel that the phone uses or purchase phones that occupy a different bandwidth.
*Preferred Networks & Airport Services*
You may be experiencing interference from other networks in your neighborhood. When you click the Airport menu are there other networks listed other than your own?
If so, is your network at the top of the list? It should be.
Go to System Preferences --> Network --> Select Airport on the left.
Click "Advanced". In the “Airport” tab note the various local wireless networks that Airport detects. Is the network you prefer to connect to at the top of the list? If not drag it to the top. Are there other networks you never intend to connect to (an old work network, or a neighbors network)? Then highlight them and click the "-" button.
Make sure “Remember any network this computer has joined” is checked.
Click "OK".
For "Network Name" be sure your network is selected and then click "Apply".
Is Airport (wireless) your primary means of connecting to your network? Is so, is Airport at the top of the list of services on the left? It should be.
Click the small “Gear” button at the bottom of the window and select “Set Service Order”.
Now drag Airport to the top of the list.
Click “OK”. Click “Apply”.
Now see if network connectivity has improved.
*Transmit Power & Wide Channels*
If you are using the 802.11n only (5GHz) radio mode, you can also select to use wide channels, which provide higher data throughput in your network.
Launch Airport Utility
Select your Time Capsule on the left.
Click “Manual Setup”.
Select “Airport” in the toolbar.
Click the “Wireless” tab.
Click “Wireless Options...” at the bottom of the window.
Adjust the “Transmit Power” to 100%.
Put a check mark in the box labeled “Use Wide Channels”. (If you are using a 802.11a/b/g (2.4GHz) radio mode then select “Interference Robustness”)
Click “Done”.
Click “Update” in the lower right hand corner.
Wait for the Time Capsule to restart and then see if your network speeds improve.
*Reduce the DHCP Lease Time*
Some have found that reducing the DHCP lease time improves their network connectivity.
Launch Airport Utility
Select your Time Capsule on the left.
Click “Manual Setup”.
Click “Internet” at the top of the window.
Select the “DHCP” tab.
Change “DHCP Lease” to a shorter time.
Click “Update” in the lower right hand corner.
Wait for the Time Capsule to restart and then see if your network improves.
Let us know if any of these suggestions improve your situation.

Can't copy with LaCie Network Attached Storage and Time Capsule/Airport

Hi,
I bought a Time Capsule to replace my recently faulty modem/router Linksys AG241 and in preparation of buying my first mac in the next few months.
Right now the network is as follows:
— 1 Linksys AM200 modem connected to the TC by ethernet and set to bridge mode
— 2 windowsXP pcs attached by ethernet to the Time Capsule
— 1 NAS (LaCie 2Big Network) attached by ethernet to the Time Capsule
Despite some initial problems configuring the modem in bridge mode, the present problem is the following:
Everytime I try to copy a file (it can be either an 4MB file or an 800MB one) I get this error window:
— Cannot copy "Filename": the specified network name is no longer available
Even when copying a file from one Share of the disk to another! However, have no trouble copying 1KB file, for example.
I've been searching throughout the internet for some days now but couldn't find any answer.
This LaCie NAS External Disk is ethernet-only and can only be connected to a switch or a router. It worked before with my older modem/router. I changed the ethernet cable by another one and I get the same result.
The Time Capsule is cofigured to distribute IPs through DHCP. Right now, I even have enabled the DHCP reservations to assign a static IP to the NAS, and to the Pcs. STill the same result.
This happens on both pcs. Still haven't tried with a wireless device yet (I don't have one).
Can anyone help me solve this?

Ok. I've ran a test on a friend's network in order to clarify if the LaCie NAS was the hardware causing this issue.
Well, it isn't. The NAS worked fine on this other network setting - which uses a different router, modem and 2 different computers.
The test ocurred in Wireless G, though, not by Ethernet connection with the computers.
*So I guess the problem must be on my Time Capsule or Modem?*
*Possibly a configuration issue.*
Does anyone has/had some problem connecting Ethernet External Disks on a Time Capsule/Airport that can share some Solution ?
Please, Help!?

Best configuration to extend wifi with Time Capsule & Airport Express

In my house I have a Fritzbox wifi router on the ground floor as my primary internet access. I have an ethernet cable going to the 3rd floor study where the Fritzbox signal is relatively weak. I purchased a Time Capsule as a backup device, but also wanted to extend the Fritzbox wifi network by plugging the ethernet cable in to the TC. I was not successful in extending the network, so I had to create a new network. When moving from downstairs to upstairs, my iphone keeps the connection to the (now weak) wifi network and I have to manually change to the (stronger) TC wifi network.
Additionally, I used to be able to successfully extend the downstairs wifi using my Airport Express (and also managed to have my speakers plugged into this for wireless usage), but do not want to additionally complicate my set-up.
So, what is the best way to connect the following equipment, ideally with the same network name, to ensure I always use the strongrst signal automatically:
Third floor:          iMac,    Macbook,   Time Capsule, Airport Express
          Ethernet cable from ground floor to 3rd floor
Ground floor:     Fritzbox wifi connected to internet

You must configure the Bridge Mode setting as the very last step before you Update the settings, otherwise the setting will change automatically.
In other words, you can change the setting to Bridge Mode, but if you make any other changes before you click Update, the Bridge Mode setting will not take effect.
Or, if you see any error messages about DHCP conflicts or Double NAT....the AirPort is not in Bridge Mode...even though you might think it is. Check the settings again.
will I still be able to set up an additional 5GHz network in parallel?
Yes

Configuring the time capsule airport wlan function as "connect to wlan", the time capsule gets a correct IP adress from the other wlans IP range, but does not assign this to the ethernet ports. With Airport express it worked, the single Ethernet port got the IP Parameters passed through!
My setup is a Vodafon Esaybox connected to ISP. Time Capsule is not able to extend the wlan of the easybox, neither airport express can do.
Only the option "connect to wlan" is succesful.
With airport express I was able to connect my Sony Bravia TV to the lan via ethernet to stream pictures, the TV set got an IP adress from the easybox.
With the time capsule the easybox dosn't find devices connected to the ethernet ports to submit IP adresses. The TV set get another IP adress (169.xxx.x.x.) in subnet mask 255.255.0.0 and I don not now where from.
My notebook is a MacBook pro.
Any idea????
Thank a lot in advance!
Kind regards
Ingo

Neverthe less, could there be the chance, that this feature could be implemnented with an firmware update?
That would appear to be a question for Apple to answer. You can make suggestions to Apple here:
Apple - AirPort Extreme - Feedback
If the AirPort Extreme and Time Capsule are configured to "extend a wireless network" they will provide additional wireless coverage....and...the Ethernet ports are enabled in this type of setup.
The "catch" here is that you must have an Apple router providing the network to be extended.

Time Capsule 4 gen. with iMac OS X Lion 3 Windows PC (XP OS, Vista OS, Seven OS) cable modem with TC as Wi-Fi. Time Machine on iMac found TC for backup easily. Have Wi-Fi access on PC XP with Airport utility but cannot create TC.

Installed today Time Capsule 4 gen. with iMac OS X Lion. I also have 3 Windows PC (XP OS, Vista OS, Seven OS). Internet Access is cable modem with TC as Wi-Fi. Time Machine on iMac found TC for backup easily. Have Wi-Fi access on PC XP with Airport utility but cannot create TC. Does the Airport utility under Windows is way to access backup capabilities with TC ?

The TC is really just an external networked hard disk plus router.. you can access the hard disk and place files on it from any computer. You can backup any computer to the TC but it will have to use a backup software in windows.. there are literally thousands available. The built in msbackup is horrible.. but you can download lots of different software and buy then online for not a lot. Macrium Reflect has a free disk image backup, and when you pay for it includes incremental. I think disk images are well worth it, as they recover much better.. and their is a proper method of recovery using a boot cd.
BTW the TC space is not endless. And it is designed to hold a large number of incremental backups.. so anything you do in backing up several machines will make the number of backups limited. Remember you can also use a usb hard disk plugged in as a Network accessible disk. But it has to be formatted HFS+ or Fat32.. the later being highly undesirable.

Do i need to set up the time capsule airport before i start backing up using time machine with my time capsule?

Do i need to set up the time capsule airport before i start backing up using time machine with my time capsule?

Some setup is generally required.. because the TC is a network device.. not a plug in via usb.. therefore it has to exist somewhere in your network.

Guest network feature of Time Capsule/Airport Extreme in conflict with DNS on OS X Server?

Hi, I want use the guest network feature of Time Capsule/Airport Extreme which requires an external DNS server but my OS X Server is the dns server...Can I configure server and airport with an external dns without messing up my OS server?
Thx Ron

If you want to use the guest network while also using your server for DNS - you will need to do the following: It's a bit painful - but it works.
On your Airport Device (Airport Extreme or Time Capsule) - in the Internet tab you will need to do one of the following:
1) Leave the DNS Servers Blank - which they will default to the DNS servers provided by your ISP.
2) Actually enter your ISP's DNS servers.
3) Enter Open DNS servers (I use 208.67.222.222 / 208.67.220.220).
The DNS servers specified in the airport device must be internet routable addresses (if you are going to use the guest network functionality) - and cannot refer to private ip address (e.g. 10.x.x.x, 192.168.x.x, etc).
Here is the painful part...on all of the devices (Macs, PCs, phones, ipads - that will be used on your "private" network 10.0.1.x - you will need to provide static DNS setting (but still allow DHCP to assign the devices IP address). You will specify 10.0.1.13 as primary DNS and 208.267.222.222 (or your ISP's primary DNS IP).
One you do this - your devices that you permanently use on your local network - will still use your server for DNS - and the external DNS - should your DNS server happen to be down.
Anyone visiting your house - will connect to your guest network - and automatically be DHCP assigned a guest IP address - and the external DNS servers that you specified in the Airport Extreme device.
This has been working great for me. I suspect that the guest network functionality is flawed in the Airport Extreme/Express and Time Capsule. Since I do not have another router that provides a guest network - I cannot say whether this issues is limited to the Airport devices - or whether this workaround would need to be done - regardless of which brand of router is providing the guest network.
In a nutshell - your household permanent devices will have to specify static DNS servers - but your guests will connect seamlessly without having to change and risk messing up any of their device settings.
If this solution works for you - Please be sure to click either "This solved my problem" or "This helped me".

Wifi with Time Capsule really slow

I have a brand new Time Capsule, macbook pro 13", and iPad (all of them less than a month old, purchased the same time). Everything work together great with the exception of my iphone 4. Using a download apps, if I download using 3G I get over 300kb/sec. Download using wifi, I get about 30kb/sec and sometime less. If I reset, I mean hard reset the time capsule and reconfigure it, I'll get amazing speed for a day or two on my iphone. Then it slowed down to crawl again. Using speedtest apps shows the speed is great at 8 to 9 mb/sec. I'm baffled.
I set my macbook pro to connect 5GHz, and the rest is automatic.
Any tips?

You have the dual "n" band enabled with your Time Capsule - the 5GHz band for your MBP, and the 2.4GHz band for your iPhone?
I have not experienced the same with my iPhone 4 when connected to my Time Capsule set up with dual band for my MBP and iPhone.

Time Capsule-AirPort Express-WDS not working together

According to everything I've read here, I've configured this properly, but it doesn't seem to be working. If anyone can help me troubleshoot this I would greatly appreciate it.
I have a new Time Capsule acting as my main wireless base station; it has a manually-configured static IP address, is plugged into my Verizon FIOS router, and is set to distribute IP addresses over wireless using DHCP. I have it set to run a 5 GHz network in addition to the regular 2.4 GHz network. I have an older AirPort Express that I want to use to extend the range of the 2.4 GHz network (the Express can only do 802.11b/g, not 802.11n), in part because we have some older devices in the house that I don't want to slow down the 802.11n network, and in part because the 802.11b/g signal doesn't reach all parts of the house very strongly. So I told the Time Capsule to make its network extendable, told the AirPort Express to participate in a WDS network as a WDS relay, and entered the MAC address of the Time Capsule's 2.4GHz network as the WDS main. Result: flashing amber light on the AirPort Express, which no longer shows up in the AirPort Utility; I had to do a hard reset in order to get the Express back (and then it had to be reconfigured again, of course). At the moment I have it just joining my wireless network, and that works -- green light -- but of course doesn't allow the Express to extend the range of the wireless network.
What am I doing wrong here?

Before there was dual band, we always told users that if they used WDS, the entire network would revert to "g", even if the Time Capsule, AirPort Express, etc were capable of "n" performance.
Your findings seem to confirm that this happens with a dual band as well.
I think it's well worth it to get the AirPort Express 802.11n. Then you can reconfigure the Time Capsule back to "Create a wireless network" and check the box to "Allow this network to be extended"
The Express"n" would then be configured to "Extend a wireless network". I use this setup and would highly recommend it. There may be a slight bandwidth loss due to overhead, but the performance is light years ahead of WDS.
If you are using the same network name for both bands on the Time Capsule, then I believe by default the Express will extend the 2.4 GHz "n", "g" and "b" band. This makes sense for most users since 5 GHz signals do not travel well over distance or penetrate obstructions well.
IF...you want to extend the 5 GHz band, the only way that I know how to do this is click Wireless Network Options on the wireless setup page for the Time Capsule and enable the option to assign a different name for the 5 GHz network.
Then you will have to configure the Express to extend this specific 5 GHz network. I never had much luck extending 5 GHz, and I wanted my iPhone to be able to use the network across the house, so I went with the simpler one network name for both bands and extended the 2.4 GHz network.
If you have a "g" device joining the extended network, it may tend to slow the "n" devices down slightly...when the "g" device is active, but it won't drag everything down to "g" levels. When the "g" device is not active, "n" devices will run at "n" speeds.
BTW, the ethernet port on the AirPort Express is active when you configure it to "extend a wireless network". This can come in handy for hooking up DVD players, etc that need an internet connection for firmware updates and extra features.
Follow up....I tried a very quick reconfiguration of my dual band AirPort Extreme (same router that the Time Capsule users) and AirPort Express using the WDS arrangement and everything did indeed drop way down in speed and performance.
Post back if you have questions. Happy to help.
