fixed : internet on wireless but not on LAN according to AirPort Utility

Question :

Lately I have had a bad and unstable internet connection. I have a Mac and it has been working fine for years. My internet provider is Vodafone-Ziggo.

I tried to find out what was wrong using the AirPortUtility.app on my Mac, and I found something strange : when selecting my wireless WiFi-network, my internet connection is presumed working, but when selecting my wired LAN-network, I get an error message saying there is no internet connection.

If it would have been the other way around, I could think of an explanation… but having wireless internet connection from my router and not LAN-internet just doesn’t make sense…

I’ve tried numerous resets of the Ziggo-modem, of my TimeCapsule and of my Mac. Nothing helps.

Do you have any suggestions on fixing this ?

 

Answer :

Even though you’ve tried most of the available options already, there is one other thing I would suggest to try :

  • make sure the UTP/Ethernet/LAN-cable is correctly connected into both your Mac and the ‘local network device’ (be it a TimeCapsule, a router, a modem, a network-switch or a wall-socket)
  • then, on your Mac : click on the Apple-icon (top-left on your Mac’s desktop screen)
  • in the pulldown menu, click on “System Preferences”
  • in the window that opens (“System Preferences”), click on “Network”
  • in the window that opens (“Network”), click on “Ethernet” in the list on the left
  • in the info that appears on the right, check if it says “Status : Connected”
  • if it doesn’t, your UTP/Ethernet/LAN-cable isn’t connected properly, so check all network-cables again until it says “Status : Connected”
  • then, click the Advanced-button
  • in the window that opens, click on the DNS-tab
  • in the info that opens, at “DNS Servers:” make sure that you have at least included one of the following DNS Servers : 8.8.8.8 (Google), 8.8.4.4 (Google), 208.67.222.222 (OpenDNS) and/or 208.67.220.220 (OpenDNS)
  • if none of those DNS Servers are listed yet, add them by clicking on the +/Plus-button bottom-left
  • then click on the Proxies-tab (of the elongated TCP/IP-button)
  • in the info that opens, make sure to remove the check-mark at both “Web Proxy (HTTP)” and “Secure Web Proxy (HTTPS)”
  • in case both were already switched OFF, I would suggest to switch both of them to ON
  • then leave the rest as is, and click on the OK-button
  • in the previous window that appears, click the “Apply”
  • now check the AirPortUtility.app again, and you should see that the internet connection is back up for both the wireless and wired/LAN connection
  • also check by opening Safari (or another internet browser) and refresh the page by clicking on the circular arrow in the address bar

That’s it !

fixed : use one printer in two networks at the same time

Question :

I have a network printer on my (private) network that I would like to make available to the people on my AirPort Guest Network, but I don’t want guests to access my private network.

Is there a way to do this ?

 

Answer :

There are options to do this, but it can’t be done the way you would find most elegant probably… the problem is the restriction in AirPort Guest Networks that users can’t connect to each other, so adding the printer to the AirPort Guest Network won’t make it available to any AirPort Guest Network user.

On the other hand, an other restriction on most network printers is that they only have one Ethernet-card that is shared between the UTP-cable port and the WiFi connection, so the cable-connection and the WiFi-connection will always have the same IP-address, making it impossible to connect the cable to your private network and joining the Guest Network using the WiFi-connection at the same time…

Your best option is to connect the Ethernet/UTP-cable and/or the printer’s WiFi to your private network and creating a separate network to be used as a Guest Network to which the printer can be connected using it’s USB-cable. Since you will need an extra wireless router or an extra (secondhand) AirPort Base Station or Time Capsule to create this separate Guest Network, you can plug the printer’s USB-cable into that wireless router / AirPort Base Station / Time Capsule.

You could also use a printer server, if it isn’t possible to connect the printer’s USB-cable into the wireless router / AirPort Base Station / Time Capsule. You can find relatively cheap print servers on Amazon.com, Amazon.co.uk or Amazon.de

Regarding the setup of your networks, you will probably be best off doing it like this :

  • set your internet modem in router mode (if you would set it in bridge mode, you wouldn’t be able to connect two separate networks behind it)
  • connect both routers (or AirPort Base Station or Time Capsule) to the internet modem
  • setup one router (or AirPort Base Station or Time Capsule) to create the private network and private WiFi network
  • setup the other router (or AirPort Base Station or Time Capsule) to create the Guest Network and Guest WiFi Network
  • make sure that the IP-ranges issued by both routers are completely different (to prevent easy connection from the Guest Network to your private network (and the other way around)
  • if any of your routers give a “Double NAT” error, just ignore it

That’s it !

the only downsite is that having such a complex network setup with multiple routers will have negative influence on your (internet) connection speed ; this difference in speed will probably not be very big if you have few devices connected, but if you have a lot of devices connected that also use a lot of bandwidth (like video streaming) you will probably have slower internet speed than you used to…

fixed : Time Capsule shuts down almost immediately after startup

Question :

I have a 1st generation Time Capsule that always used to work fine, but recently it shuts down almost only seconds after I turn it on.

How can I solve this ?

 

Answer :

Most of the time, this problem can be solved rather easily.

The cause could be a broken HardDrive inside your Time Capsule (if that’s the case, go here to see instructions on how to replace the HD), but most of the time this specific problem turns out to be an overheated (and therefore broken) power unit.

Even though this type of Time Capsule is marked obsolete by Apple, it will still function in your current WiFi network and can still be configured using the current AirPort Utility app version 6 and newer.

The main problem is probably not going to be to replace the power unit, but finding a new power unit. You might find one on Amazon, but since it will probably be a secondhand item, your will probably have more luck searching for an “A1254 power unit” on eBay, AliExpress or Google Shopping

When you have found a new (secondhand) A1254 power unit, you can build it into your A1254 “1st generation” Time Capsule this way :

  • put the Time Capsule upside-down and use a hairdryer to heat up the rubber base plate and loosen it’s glue (if you don’t do this, you will probably rupture the base plate when you try to take it off)
  • then follow the iFixit manual for replacing the power unit and make sure not to skip the important comment at Step 2 : “The two screws in the top center of this picture should not be removed at this time. They are locating pins on the hard drive.”
  • after taking out the broken power unit and putting in the new (secondhand) power unit in, put your Time Capsule back together doing the iFixit steps in reverse order
  • after plugging the Time Capsule into the power, you can reinstall it into your WiFi network using the AirPort Utility app on your Mac (or on your iPhone/iPad)

That’s it 😉

fixed : upgrade broken HD in old Time Capsule

Question :

My 1st generation Time Capsule always used to work fine, but now the internal HardDisk is broken.

Can I replace the HardDisk easily ?

 

Answer :

Yes you can.

In the ‘old’ flat Time Capsule (like the A1254 “1st generation” Time Capsule), the HardDrive is rather easy to replace. And even though Apple has marked this TimeCapsule ‘obsolete’ it is still able to preform properly and it can be maintained using the current AirPort Utility version 6 and newer.

To do so, follow these steps :

  • get yourself a new HardDisk, preferably a low-energy HD like the Western Digital WD Green 2TB or 3TB (get it on Amazon.com, Amazon.co.uk or Amazon.de) ; these low-energy HDs are especially suited not only because of their low power consumption, but also because of their ability to stay cool during operation since these old TimeCapsules tend to overheat when a regular HD is installed
  • then, place the TimeCapsule upside-down and warm up the rubber bottom plate with a hairdryer to loosen the glue (if you don’t do this, it is nearly impossible to get the rubber bottom plate of without rupturing it)
  • then follow the steps as outlined in this manual by iFixit and be sure to read the important note at Step 2 : “The two screws in the top center of this picture should not be removed at this time. They are locating pins on the hard drive.”
  • then replace the HD and rebuild your TimeCapsule doing the MacFixit steps in revers direction
  • when done, plug your Time Capsule into the power and access it using the AirPort Utility app on your Mac (or iPhone/iPad)
  • in the AirPort Utility app, select the TimeCapsule’s icon and click Edit
  • in the window that opens, go to Disks, then click Erase Disk
  • when that’s done, your new Time Capsule’s HD is ready for use

That’s it 😉

fixed : retrieve WiFi-password from iPhone [without hacking]

Question :

We have a password-protected WiFi-network at our local sports club. My iPhone automatically logs on when I’m near, but now my son is a member too and he would also like to connect to the WiFi when he’s around. Problem is, nobody seems to know the password… I’ve typed the password once long ago, but I didn’t write it down… Is there any way to see the password that is stored on my iPhone ?

 

Answer :

Yes, but you need a Mac and iCloud for it.

To be more precise : you can’t retrieve passwords on your iPhone (or iPad) the way you can on your Mac, by just opening the Keychain utility.

But there’s a way around this :

  1. on your iPhone, go to Settings –> iCloud
  2. there, make sure “Keychain” is set to “On”
  3. then, on your Mac, go to Apple [top left corner] –> System Preferences –> iCloud
  4. in the window that opens, make sure there’s a checkmark in front of “Keychain”
  5. then, on your Mac, click anywhere on your desktop
  6. then make sure “Finder” is displayed top left, next to the Apple-icon
  7. then press the [SHIFT]+[CMD]+[U] key-combo on your keyboard
  8. in the window that opens (named “Utilities”) double-click on the “Keychain Access” icon
  9. in the window that opens (named “Keychain Access”) select “iCloud” from the list on the left
  10. now, find the name of the WiFi-network you are interested in, and double-click on it
  11. in the window that opens (named like the WiFi-network), make sure the “Attributes”-tab is selected
  12. then, put a checkmark in front of “Show password:”
  13. in the (unnamed) window that opens it is said ‘Keychain Access want to use the “Local Items” keychain.’ typ your Administrator’s password and click “OK”
  14. now, the WiFi-password you are looking for will be displayed in the previous window (at “Show password:”)

…that’s it !
