Q: Connecting Printer to Thunderbolt Display Ethernet on El Capitan?

I have a complex setup and just upgraded from Mavericks to El Capitan and now my printer no longer works. I had it connected via ethernet on a different subnet through a Thunderbolt display that is connected to my Macbook Pro where the printer was 192.168.2.2 and the ethernet for my Thunderbolt Display was 192.168.2.1 with 255.255.255.0 and no gateway.

But now with El Capitan I can no longer ping 192.168.2.2 from my MacBook Pro but I'm not 100% sure I have it configured as before. I had previously found somewhere online that gave me the idea to set up this way but Google fails me now and I cannot find that the answer online again (I should have bookmarked it!)

Below is my full config. It was the only way I could get the new generation Apple TV to actually connect to the Internet which is why it is set up this way (and I spent over 8 hours getting that to work. Makes me feel very snide about this):

  1. Comcast Router for connection to Internet and providing WiFi and DHCP as NAT gateway 192.168.1.1
  2. Apple Time Capsule #1 connected to Comcast Router via ethernet and Wireless Network offwith manual IP address 192.168.1.x
  3. Apple TV with manual IP address 192.168.1.x and using Time Capsule #1 as gateway (this was the trick to get Apple TV to work)
  4. Apple Mac Mini as a media server connected to Time Capsule #1 via ethernet with manual IP address 192.168.1.x and using Comcast Router as gateway.
  5. Apple Time Capsule #2 connected via WiFi and Wireless Network joined to the Comcast Router WiFi with manual IP address 192.168.1.x and Comcast Router as gateway.
  6. MacBook Pro connected via WiFi using DHCP from Comcast Router on 192.168.1.x with Comcast Router as gateway AND connected via Thunderbolt display ethernet as 192.168.2.1.
  7. Canon Printer connected via Ethernet to Thunderbolt display with a static IP address of 192.168.2.2 and a gateway of 192.168.2.1.

My memory was that that 192.168.2.1 and 192.168.2.2 previously worked for printing but does not any longer. Did I forget to reset something El Capitan's install threw away, does El Capitan not support this, or is there some other approach to get the printer working? (FYI I stopped using WiFi for the printer because it was very unreliable.)

Thunderbolt Display (27-inch), OS X El Capitan (10.11.2), See the question

    Hey mikeschinkel,

     

    I'm sorry to hear you are having an issue with printing after updating your operating system to Mac OS X 10.11 El Capitan. Let's see if we can get you back up and running.

     

    I would suggest that you start troubleshooting using the steps in this article - Get help resolving printer issues on your Mac.

     

    Thanks for using Apple Support Communities.

     

    Happy computing.

    TThanks for the reply.

     

    However, my question is really a networking question, not a printer question.  In hindsight I can see that the title that I used would have led you to believe otherwise.

     

    What I neede to know is how to configure networking  such that my Macbook can communication using PING with a printer that is connected to the Ethernet port on my Thunderbolt display.

    Can't really assist you because my network is probably more complex than yours but I don't use manual ip addresses. I'm guessing your TC#2 may not be in bridge mode and it should be.

    Thanks for the attempt.

     

    Turns out it worked as configured.  Now sure why but the next day I found the printout on the printer!
