Time Capsule: Wired connection works but cannot connect via wifi to net

Hi all,
I've had a Time Capsule for a year or so. I've been having problems with connectivity over recent months and I'm not sure where the issue is.
I have plugged in an ethernet cable joining my MBA to the TC, and another from the TC to the wall socket. I can access the internet without any problems.
However, if I unplug the ethernet cable from my MBA (or indeed if I don't plug it in in the first place) then I cannot connect to the internet. I can still back up to Time Machine etc., but nothing can get 'through' the TC.
Also, if I turn Mobile Data off for my iPhone, I cannot then access the internet via WiFi through the TC.
Any ideas as to how to fix this? The TC is in bridging mode, which has worked fine before. All suggestions welcome!

Ok.. let me try again..
Going back to your first post.
I have plugged in an ethernet cable joining my MBA to the TC, and another from the TC to the wall socket. I can access the internet without any problems.

When you plug in via ethernet the MBA works but not by wireless..
Now add that to the new info.
The campus network relies on each PC's individual MAC address and then assigns IP addresses as required;
Is the MAC address actually registered?? Because the MAC address of the ethernet port of the MBA and the MAC address of the wireless are different.
If the MAC addresses are not registered.. how does the Uni know the difference between a computer and a router??
You are not allow to run a router that feeds DHCP into the uni system.. but they cannot know what you have behind the MAC address of the item plugged in. A computer or a router.
So the TC has to be in bridging mode - which has worked perfectly well previously
Try releasing the MAC address to the PORT.. because the uni might have decided they don't want hubs connected either.. therefore the address of whichever device that is plugged into the wall is registered at the switch and will not allow a change for a fix period.. that is one way to stop people changing stuff around.
Try powering off the TC.. when you use another item.. or change from ethernet to wireless.. then power up the TC again and then power up the device .. eg the wireless on the laptop.. If it fails, it is not the TC that is causing it.. because in bridge the TC is completely dumb. It has no ability to control the MAC address being sent to the main router. None whatsoever.
If your TC recently upgraded to 7.6.4 firmware.. though.. well it can do all kinds of nasties.. flash it back to 7.6.1 and factory reset it.. and hope it works as it did before.. if not the uni changed the system to prevent your TC acting even as a hub.

New Time capsule not connecting to wifi, New Time capsule not connecting to wifi

I just got a 2T time capsule, and it picked it up on the wifi the first time, and I went through and clicked what I wanted for it, but now it's not getting picked up on the wifi. It's about as useful as a brick right now.
I'm on an imac and I just want to use it for backup, and not a router. I want to do half for time machine backup, and then half for movie files to access from the time Capsule on my iMac.

Are you using join a wireless network on the TC?? This is a mess..
Please describe the whole existing networking.. and how you are trying to fit the TC into it.

Time Capsule + Wired Connection for Xbox 360 Problom

i just bought a eithernet wire for time capsule since my my wireless network aint working i got it to work for my ps3 no problom but appertly the 360 is doomed all the way around it ses thers a problom with my ip adress when it seems fine im verry comfused at this matter is ther a way to fix this problom or even get the wireless way back aswell much aprecited

XBox360 could connect to an Express which is wirelessly or ethernet to the TC. You should be able to connect wireless to TC anyway w/o the Express. When testing that xbox360 go to "other." Change security password to WEP from WPA2 if you have to...

TIME CAPSULE wired connection=28Mb/s while Wireless Connection=3.10 Mb/s??

As stated above, I have a TIME CAPSULE that is allowing me approx 28 Mb/s wired directly, while only allowing me 3.10Mb/s wirelessly (and the wiress computer MACBOOK PRO) is literally 5 feet from the TIME CAPSULE....
Is this normal? Shouldn't I be getting a better speed wirelessly...? I am using www.speedtest.net.
Your advice is appreciated...
Thanx.
Kevin

Hello kevinperryjr. Welcome to the Apple Discussions!
Your Time Capsule is capable of providing a bandwidth up to 1000 Mbps wired and 300 Mbps wireless ... but this is for devices on the local network connected to the TC itself. Your Internet connection bandwidth is controlled by your ISP & current Internet traffic conditions.
Speedtest, and a number of other utilities like it, attempt to measure the bandwidth from your computer to a file server at a remote location ... and thus, is a combination of both Internet & local network bandwidth. Typically, a wired connection will provide better bandwidth results.

Time Capsule and Thunderbolt HDD very slow access via wifi enabled MacBook Air

I have a Q-RAID thunderbolt external drive attached to the Time Capsule. I use it to archive movies for viewing via a media server around the house (mostly via WIFI). Using my MacBook Air to access the files, performance is very spotty. Sometimes it's very fast (monitoring the "Data Received" via Activity Monitor typically > 3MB/sec) and sometimes it's very very sluggish (Data Received < 200kb/sec). Any idea? It's not a home network issue b/c when it's slow, i test it immediately against a networked iMac and i can access large files just fine (Data Received > 2MB/sec). Thanks.

I have a Q-RAID thunderbolt external drive attached to the Time Capsule.
You are killing it.. The connection on the TC is USB2. USB is slow.. slow .. slow interface. It is very CPU intensive.. and depending on what the TC is doing it can slow it down like crazy.. the fact is, the TC was designed to plug in a simple drive.. not a raid array. The access to files in the array .. frankly it is a wonder it works at all. But you should move the Q-RAID to a computer with thunderbolt port and share the disk to the network.. it will go at 10times the speed. or maybe 50times or 100times when you have slow speed. TC is not suitable.

Help! Time Capsule not connected to the Internet

Hi everyone!
I have this problem, and hope someone can help me.
In my house I have this network
Modem/Router Netgear DGN2200 connected via ethernet to Airport Express.
Airport Express is set to create a wireless network, bridge mode.
In the house I also have a Time Capsule set to extend the wireless network, bridge mode.
Time Capsule is connected via ethernet to my TV decoder to have extra services through the Internet.
Ok. All worked fine until a couple of days ago.
Then, I didn't change anything but Time Capsule (and so the TV decoder) seems to have no acces to the Internet anymore.
But Time Capsule is still available on the local network, so I can access to it, make backups and so on.
What should I do?!
Thanks for your help and sorry for my bad English.
Matteo

Did you try a simple reboot of the network devices.. turn off all the network stuff..
Restart in correct order..
1. Modem.. wait 2 min.
2. Express.. wait 2min.
3. TC.. wait 2min.
Then try the TV.. if it doesn't work reset both the express and TC to factory.. and redo the setup.. you had them setup correctly but please use SMB names.. since the TV will not talk apple.. SMB names are short.. 2-20 characters.. no spaces and pure alphanumeric.
so for example the name of the Express.. AEx Name of the TC.. TC1
Name for wireless. Aex24ghz
Use a different name for 5ghz if your Express is a dual band latest model. Aex5ghz
Use fixed channel so that it is locked.. eg. 2.4ghz on channel 11 5ghz on channel 40.
The TC will follow the wireless exactly.
See how you go.

Can I connect an external hard disk to time capsule? I tried but it doesn't show up. What would be the reason??

Can I connect an external hard disk to time capsule? I tried but it doesn't show up. What would be the reason??

The USB drive must be formatted for Mac in Mac OS Extended (Journaled), or if you want to use both Mac and Windows files, the drive can be formatted in FAT32.
A number of drives are formatted for Windows only in a format called NTFS. This willl not work on the Time Capsule.
In addition, the USB port on the Time Capsule is under powered. You almost always have to use a powered USB hub when you connect a drive to the Time Capsule...even if the drive has its own power supply.

Can i get the time capsule to automatically back up my file from my Mac Book Air but have certain files which are only stored on the time capsule and not the computer? Then can i access these files only on the time capsule without connecting it?

You can, but how are you going to back up those other files? When (not if) your Time Capsule fails, you risk losing them. See #Q3 in Using Time Machine with a Time Capsule for details.
Then can i access these files only on the time capsule without connecting it?
Not sure what you mean. You have to connect a computer, either via Ethernet cable or wirelessly, to read or write to the disk.

Time Capsule Not connecting to internet

Hello. So recently I received a new iMac for Christmas and knowing that my wireless network is setup with MAC address filtering, I used my working laptop to connect to both the Airport Extreme and Time Capsule to add the iMac to the network. That worked and my iMac has been able to connect to the network no problem.
Let me explain what my network setup is before I tell about the problem:
I have the latest generation Airport Extreme (Dual Band II) and a first generation Time Capsule (1TB).
The Airport Extreme is connected to the internet by cable modem and the Airport is the main router sharing a single IP address.
I connected the Time Capsule to the Airport Extreme through Ethernet and set it up automatically with Airport Utility to extend over ethernet.
Now up untill now, I had no problems but since I got my iMac, I haven't been able to ever get a list of the Airport devices connected to the network, while connected to the Time Capsule, however, when connected to the Airport Extreme 5GHz network, I'm having no problems.
And today, the Time Capsule wouldn't connect to the internet over wifi, and all other devices wouldn't either. Of course, I tried to connect to the base station, but Airport Utility wouldn't display any devices connected. This happened with my MacBook as well.
Since connecting to the 5GHz network from the Airport Extreme, I have no problems with internet or Airport Utility. After a while though, the Time Capsule connected to the internet again.
Would someone shed some light on the situation?

I normally use the manual setup mode so I'm not sure what exactly is the end-state when choosing to extend a wireless network with the Time Capsule (TC) connected to the AirPort Extreme Base Station (AEBSn) by Ethernet.
I am guessing that the AirPort Utility configured the TC as a bridge to allow the AEBSn to still provide both NAT & DHCP services for all wired or wireless clients connected to either router.
Let's start by double-checking some settings on your TC. Please provide the following TC settings from the AirPort Utility:
AirPort Utility > Select the TC > Manual Setup > Time Capsule > Wireless
o Wireless Mode = ?
o Allow this network to be extended = checked or unchecked?
o Radio Mode = ?
o Radio Channel Selection = ?
Time Capsule > Access Control
o MAC Address Access Control = ?
Internet > Internet Connection
o Connect Using = ?
o Connection Sharing = ?
Internet > TCP/IP
o Configure IPv4 = ?

Configure time capsule to connect to my wi-fi router?

I have my 1Gb Time Capsule connected to my iMac using an ethernet cable and it is now FINALLY backup up my iMac.
However, no matter what I do the light on the front will ONLY flash yellow and there is seemingly no configuration that will allow it to talk to my wi-fi to let it talk to the Internet and so stop it.
Is there any meaningful documentation anywhere (other than the scant manual that it came with) that can help in anyway?

Yes, I understand but how is the TC connecting to the Dlink. If it doesn't connect it will have no internet.. without internet it will give you all the error messages.
Looking at the network preferences for Wi-Fi, my iMac is given the IP address 192.168.0.104; subnet mask; 255.255.255.0; router, 192.168.0.1. The DNS server is shown as 192.168.0.1. This configuration allows me to communicate wirelessly to the Internet.
The Ethernet connection (in network preferences) is shown as using DHCP; IP address, 169.254.206.220; subnet mask, 255.255.0.0.
In AirPort utilities, the IPv4 address is 169.254.156.234; subnet mask, 255.255.0.0; and it connects using DHCP.
Wireless from dlink is working..
The TC is not setup correctly.. so it is failing to give the computer an IP address. This is expected. The 169.254 address is self generated.. the two happened to find each other as both are on 169.254.. but it will not be stable.. this is because you have selected the wrong mode.. I suspect extend wireless.. but you cannot extend wireless unless the other router is another apple.
What are you trying to achieve?? If you want to just use the TC for backup by ethernet.. then give the computer a static ip.. 10.0.1.10, subnet 255.255.255.0 do not use dns or router IP. Turn off ipv6.
If you want internet via the TC, you must connect the TC to the dlink.. and by far the best way is ethernet.. if that is impossible.. then you can join the TC to the dlink.. you cannot extend. When you join ethernet ports will be turned off. It will become a network item via wifi from dlink and slow.. very really slow.

Time Capsule Internet connection issues??

I just got a new time capsule and it works great with my computer. Im trying to connect another computer to it and it connects to the wireless but says it is not assigned an IP address so it wont go online. But i know that the TC has connectivity because i'm using it with my other computer. Please Help! probably something easy..

If you don't have full admin access to the computer then there is nothing much you can do about anything.
If your connection is not "home" then the firewall can block you..
I did ask the question.. do you get internet ok before you turn on the VPN?? If so as per Tesserax comment.. it is a setting in the VPN. And it sounds like there is nothing you can do about it anyway. If you cannot get internet no matter if the vpn is on or off.. then the computers firewall is blocking you. Turn off the firewall if you have sufficient privileges to do so.. otherwise.. put the Asus back and bridge the TC to it. There is nothing wrong with that setup.. !!
As a general piece of advice should I just keep my former Asus router and use the TC for backup only, or can this be fixed and is it a better router?
Since you have not given us specifics for the Asus we cannot offer any opinion on its comparative worth vs the TC. But Apple routers are great for Apple networks.. they are much less good for PC networking.. especially things like upnp are missing. The best is what works. If it doesn't work and you don't have admin access on the PC.. then for now, you are better returning to the setup that works.

I can't get my airport time capsule to connect to the internet

I can't get my new airport time capsule to connect to the internet. It works fine with my linksys router

We cannot help with that amount of info..
What internet type and modem do you have? Exact modem make and model may help.
Is the linksys router also the modem? You do know there is no modem in the TC?
How is the Linksys authenticating if it is plugged into the modem??
If cable did you shut down the cable modem for at least 20min to change the router.. this is always required with cable system.. often the time is longer.. one hour or overnight even.

I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data and it does not show on the desktop when connected.

Ok if disk utility was able to verify the drive I doubt there is any problem.. are you trying to open a TM backup??
You need to mount the sparsebundle then check the actual info inside the bundle.
Don't use disk warrior.. if the disk has verified then unless you deliberately deleted files there is nothing that is going to do.
Pondini has a lot of stuff about getting access to the sparsebundle.

But if you have copied info to the TC that is now gone.. and the disk is ok.. I am not sure.. the TC will not have deleted the files itself.

Time Capsule not connected to Ethernet?

Hello,
I walked in to my office two days ago and the amber light was blinking with an occasional green (on my Time Capsule).
The reported error was that the ethernet was not connected. It was. I ultimately disconnected the ethernet cable from my Time Capsule and connected directly to my iMac. After some configuring issues I was on line. Did what I needed to do and shut down.
Next day I decided to try powering down the Time Capsule and re-connected the Ethernet cable. Everything worked fine just like it has for well over a year now.
I figured maybe the cleaning crew bumped the power and everything was fine.
No dice.
Came in this morning and the Time Capsule is blinking amber again (with an occasional green) same issue. "no ethernet connected."
Now I am connected directly to the IMac and asking for help.
Please.
Thanks in advance for your help.

On our TC, the TC shows a green light even when it refuses our computer/device wireless connections and says the password is invalid. However, I left the house for three hours and am now on my laptop and it is apparently working normally. I plan to watch it very closely for the next week and see what happens.
I have read on here (and other Mac-centric review sites) that TC's are very unreliable, have slower than average wireless connections (and short ranges in apartments, especially through walls/several rooms), and fail within 18 months -- all of which is considered "normal" lifespan by Apple (as confirmed by the Apple employees at the San Diego Store in Fashion Valley).
I don't plan on purchasing another TC, and likely not even an Airport extreme. I will look at buying a more reliable wireless router with stronger (farther) connections and connection ranges. I love apple products and have used them to the exclusion of others for over 15 years, but this is really annoying (and my friends have much better wireless networks!).

Must Time Capsule be connected by cable to the DSL Router?

The answer to this question maybe obvious, but not to me: I have a router DSL, via which I get my WiFi internet connection to 3 MACs at home. I'd like to use the versatility of Time Capsule to back up wireless and even do so for each MAC that I have. My question is: *_must Time Capsule be connected by cable to the DSL Router_*, or will it detect it wirelessly once it is plugged into the power mains?

I think that if your router supports [WDS|http://en.wikipedia.org/wiki/WirelessDistributionSystem] then you might be able to get it to work. The problem is that WDS is not a very good standard so there's no guarantee it'll work.
[Here is a site|http://jeremy.zawodny.com/blog/archives/002812.html] discusses the topic at length.
