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 !

enjoy 😉

fixed : SPL-C ERROR page printed by Samsung printer

Question :

when I tried to print to my Samsung printer via my Home-network today, the spooling process was very slow, then hung, and then a printed page rolled out of the printer with this text only :

SPL-C ERROR – Disconnected from Host. Please check the connection and try again.

POSITION : 0x3dc5 (252981)

SYSTEM : src_5.59/os_hook

LINE : 1978

VERSION : SPL-C 5.59 05-04-2012

So I restarted the printer, made sure there wasn’t any paper stuck, and tried again. This time I the spooling process was very slow again, hung again, and a similar page rolled out of the printer with this text :

SPL-C ERROR – Disconnected from Host. Please check the connection and try again.

POSITION : 0x15ea5 (89765)

SYSTEM : src_5.59/os_hook

LINE : 1978

VERSION : SPL-C 5.59 05-04-2012

So despite the difference in ‘position’, the problem remained.

What can I do to solve this ?

 

Answer :

This seems to be a weird bug popping up on some Samsung printers connected to Macs once in a while. To solve this problem, do this :

  • quit any printing jobs that are active
  • shut down the printer (take the power cable out)
  • on your Mac, go to System Settings > Printers & Scanners
  • there, delete the problematic printer (by selecting it in the list and clicking the minus-button)
  • then, restart your Mac
  • switch the printer back on (reconnect the power cable)
  • login on your Mac
  • go to System Settings > Printers & Scanners
  • add the printer to the list again (by clicking on the plus-button, and selecting it from the printers found)
  • then close the System Preferences and try printing your document again

That’s it !

fixed : USB-to-Ethernet-adapter not working on Nintendo Switch

Question :

I would prefer to connect our new Nintendo Switch gaming console to the Internet using a cable, as I did with our Nintendo Wii-U. But the USB-to-Ethernet-adapter that was working perfectly on our Wii-U isn’t even recognized by the new Nintendo Switch.

What is wrong ?

 

Answer :

There are 2 sides to this problem, and you might even have to take care of both :

-1-

To use a wired ethernet-connection on the Nintendo Switch, you need to keep the Switch tablet inside the base station. If the tablet isn’t inside the base station, the Switch can’t access the wired ethernet-connection, as there is no wireless connection between the tablet and the base station. Even when docked in the base station, it is the Switch tablet that connects to WiFi directly. There is no WiFi-module inside the base station.

So, follow these steps to get it to work :

  • open the lid on the back of the base station and unplug the power adapter-cable
  • make sure the ethernet-cable is connected to your modem router
  • plug the ethernet-cable into your USB-to-Ethernet-adapter
  • plug the USB-to-Ethernet-adapter into the base station (preferably the USB-port under the lid on the back, as that is a USB3-port)
  • then replug the power adapter-cable into the base station and close the lid
  • then put the Switch tablet into the base station and turn on your TV
  • Go to Settings, then Internet, then Test Connection
  • If the info listed says “Wired Connection” you’re okay and your Internet connection speed will be displayed in a few seconds
  • If not, repeat the above steps and make sure all cables are plugged in properly

-2-

The Nintendo Switch gaming console will only accept USB-to-Ethernet-adapters that are based on the ASIX AX88179 chipset. The only officially supported USB-to-Ethernet-adapter is the Hori NSW-004U Switch LAN Adapter, but any adapter based on the ASIX AX88179 chipset should work perfectly.

buy the officially supported Hori Switch LAN Adapter on Amazon.com here

buy the officially supported Hori Switch LAN Adapter on Amazon.co.uk here

buy the officially supported Hori Switch LAN Adapter on Amazon.de here

Or you can spare yourself some money by buying one of these (note that these are all USB3, which makes them a cheaper and faster alternative to the Hori-adapter that is only USB2) :

fixed : broken power adapter for Umax SOHO ethernet switch

Question :

I have an old Umax SOHO 1OHO8 ethernet switch that I would like to use in my LAN-network, but the power adapter has a very strange problem : one of the pins that go into the wall power outlet has come loose, and now ‘retracts’ whenever I plug the power outlet.

I already tried gluing the pin back into the power adapter with superglue, but I can’t fasten it, so it keeps coming loose. I also tried using an adapter plug, but I couldn’t find one that enabled me to keep the pin from retracting…

What can I do to fix this ?

 

Answer :

Just buy a new one.

You probably won’t be able to find the original one, but you will be able to find a new generic one with the correct specs.

The specs of the Umax SOHO 1OHO8 power adapter are :

  • AC input 230V (so 100-240V will do)
  • DC output 7.5V 1A (= 1000mA)
  • output plug/pin 5.5×2.1mm (= 5.5mm outside diameter & 2.1mm opening diameter inside)
  • output plug/pin polarity : MINUS outside & PLUS inside

You can get a US-version replacement here : US power adapter 7.5V 1A 5.5×2.1mm

You can get a UK-version replacement here : UK power adapter 7.5V 1A 5.5×2.1mm

You can get a EU-version replacement here : EU power adapter 7.5V 1A 5.5×2.1mm  (note that this one actually has a 5.5×2.5mm plug that is compatible with 5.5×2.1mm)

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 : “No Volumes Found in backup”-error

Question :

I was trying to get Migration Assistant-app to put all my data on my new Mac, but when I select the sparsebundle backup-file from Time Machine in Migration Assistant, I get an error : “No Volumes Found in backup”.

How can that be ? I’ve made a new TimeMachine-backup just minutes before, and I didn’t get any errors there… what is wrong ?

What can I do to fix this ?

Answer :

Time Machine is great. But there seems to be a bug in the backup-software that causes this “No Volumes Found in backup”-error you’ve encountered. Normally, this error-message should only be displayed when a sparsebundle backup-file is corrupt (for some reason), but it turns out that it is now also displayed when a sparsebundle backup-file is incomplete…

This is probably due to a disconnection from the backup-disk during the TimeMachine-backup process (for instance because of shutting down the Mac, or switching from WiFi- to Ethernet-connection or vice-versa, during backup).

If the original files are still available on your Mac, the solution is rather simple : just go back to your Mac and use Time Machine to make a new backup. If you want extra insurance to prevent this error, either make a new Time Machine backup to a new/fresh harddrive (preferable an external USB- or FireWire-harddisk), or follow the backup-routine outlined in this post.

If the original files are no longer available on your Mac (e.g. your Mac is stolen, sold or you’ve just done a clean install on it, wiping off all of it’s data), you are in trouble…

…in that case, you could try using Disk Utility to repair the sparsebundle-file. If that works, you are in extreme luck… if that doesn’t help, you have very few options other than using the Terminal-app or a specialized expensive retrieving app like DiskWarrior (the cheaper knock-offs turn out not to work in most cases… too bad…).

I will be posting instructions on how to use the Terminal-app for this shortly (in a new post).

tip : make sure your TimeMachine-update is useable

Question :

While doing a regular check on my Mac with Disk Utility, it just informed me that I have a potential hardware failure, should save a many data as I can and reinstall.

So I was planning on doing a TimeMachine-backup and disk-reformat, followed by a clean install of OSX and copy-back from TimeMachine.

But… I recently found reports on a bug in TimeMachine, that might prevent TimeMachine from recognizing the latest backup…

Is there a way to make sure that my latest TimeMachine-backup is useable ?

 

Answer :

This bug seems to occur with unfinished TimeMachine-backups, either due to disconnection, unplugging or switching from WiFi to Ethernet or vice-versa…

As with all things in life, nothing is 100% sure or secure…

But if you want near-100% assurance that your latest TimeMachine-backup will work after a ‘clean install’, do this :

– make sure your Mac is connected to your TimeMachine-backup-disk in only one way, so if it’s an external harddisk disconnect the Ethernet-network cable and set AirPort/Wifi to OFF, to have the connection ‘only via USB’ or ‘only via FireWire’ and if your TimeMachine-backup-disk is a NAS or TimeCapsule, disconnect from AirPort/WiFi (and preferably connect the Ethernet-cable from the NAS or TimeCapsule straight into your Mac, and if possible, stop all other network-connections over Ethernet, by disconnecting all cables, and shutting down AirPort/WiFi) to have the connection ‘only via Ethernet’

– do a new “Back Up Now” in TimeMachine, and make sure it finishes completely before you do anything else (preferably, shut down all other apps before backing up also)

– then startup the Migration Assistant-app (from the Utilities folder in the Applications folder), and type your Mac’s administrator-password when asked

– in the first window, select “From a Mac, Time Machine Backup or startup disk”, and click “Continue”

– in the next window, select the disk that your TimeMachine-backups are on (if you’re on a Time Capsule, you will need to type your TimeCapsule-password when asked), and click “Continue”

– in the next window, a list of all backups (a.k.a. sparsebundles) available on the disk will be displayed ; now you will have to wait a little for each sparsebundle to display what the date is of the backup-version that can be retrieved… if that date matches today’s date, you have a perfect backup available, and you can exit the Migration Assistant-app by repeatedly clicking the “Back”-button

…but if the date is different, or the “No Volumes Found in backup”-error is displayed, your backup is useless for easy recovery ; you will have to exit the Migration Assistant-app, and start over the entire backup-routine explained above, and then check again in the Migration Assistant-app …you have to keep repeating this entire routine until you get today’s date displayed below the backup’s name

If you do not do as described above, you are in serious, enormously time-consuming trouble…  (even though this doesn’t always mean that your personal data is lost… everything might be lost, but… it could also mean you will have to repair the sparsebundle-files and/or it could also mean that you will have to copy everything back ; folder-by-folder or even file-by-file… either in the Time Machine-app or in the Finder ; and all applications will have to be manually reinstalled again…)
