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 : 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)

enjoy !
