Question: Airport Extreme Oddness

I've having a very odd problem and I think it's with my airport extreme. It started last night when I tried to print to my wireless HP printer and was told the printer wasn't found. However, I could find the printer in the control panel but when I tried to re-add the printer I just got an error.


Then my NAS, which is connected to the Airport via Ethernet went offline - couldn't be found. And slowly over the past couple of days all my Nest alarms and thermostat have lost the wireless connection and I can't get them re-added. The weird thing, though, is that the internet seems to be working find through the Airport - I'm using it right now. I've tried restarting the base station several times and de-connecting / re-connecting the items connected to the unit via ethernet but it doesn't seem to be working.


Has anyone ever experienced anything like this before ? Usually a peripheral either works or it doesn't, this thing seems to be half-a$$ working and I'm at a loss.

Sorry, but I’m at a loss to know what else I can offer at this point. You may need to hire an IT expert in your area to take a look at your situation and potentially offer a solution. Good luck!

Power off the modem completely by pulling the power cable from the back of the device or pulling the power supply from the AC wall jack.


Leave the modem off at least 60 minutes to allow the equipment back at the cable company to fully reset and issue a new fresh IP address. Better to wait longer......2-3 hours.....if possible.


Power off everything else on the entire network as well.


After the modem power down period, start up the modem and let it run for 5-10 minutes by itself.


Then, power up the AirPort Extreme and let it run for 5-10 minutes.


See if your Mac will connect. If it will, power up another device. If it connects, power up another device. Keep powering up devices one at a time checking as you go. Report on your results.

Yes, it may be possible; however, I would suggest that you do the following:

  1. Try using a static local IP address for your printer instead of using DHCP to assign it an address. Choose an address outside of the default DHCP range of: 10.0.1.2-200, to something like: 10.0.1.210
  2. Change the IPv6 setting to: Link-local only.

What happens if you open AirPort Utility on your Mac and click Edit in the smaller window that appears?


Can you see the tabs for Base Station, Internet, Wireless, Network, Disks at the top of the screen?

If yes, click on the Network tab, and report on the setting that you see for Router Mode. It will likely either be DHCP and NAT......or.....Off (Bridge Mode).


Next item......we need the make and model number of your modem to know whether the setting for Router Mode is correct for the type of modem that you have.

OK I did as you said, everything is working except for the printer. On the printer display I"m getting an "invalid WPA passphrase" error, but I know I'm entering my wi-fi password correct. I hard reset the printer before I powered it down last night, and did it again this morning. No help there.

Since all of your other devices will connect, this is clearly a printer problem, not an AirPort Extreme issue. But, we can try to help.


What is the make and model number of the printer? We ask because other users who see this post might have the same model and be able to offer some tips on getting the printer working again.


In the meantime, please check online support with your printer manufacturer for troubleshooting tips and suggestions on the printer.

The report indicates that the security has been changed on the AirPort router, but this is not possible if all that you did was power off the AirPort and then power it back up. So, the report is not correct unless you have manually changed some of the settings on the AirPort.


Very few users have MAC Access Control set up, but if you do, chances are you would know it, since you would have had to have gone through a long and detailed process to set up "rules" for each device that connects to your network.

As Bob has mentioned, HP has a support page for this printer.


You may just need to factory reset this printer, and then, set it back up to work on your network.


Page 114 of this printer's User Guide covers resets and pages 155-157 covers how to set up the printer to connect to a wireless network.

I've spent the last two hours trying to get the printer connected to my network, when I finally did get it connected and added to the system nothing will print. I get this error "Unable to connect to ‘HP Color LaserJet MFP M477fdw (51C8FC)._ipps._tcp.local.’ due to an error. Would you still like to create the printer?"


I answer 'yes' to create the printer, but nothing will actually print. The print window shows the printer offline and/or states it is not responding.

Ok, a few things come to mind:

  1. Did you configure this printer to use a static local IP address or to get an IP address from DHCP?
  2. Is your Mac configured for "IPv6 Link-local only" or "IPv6 Automatic?"

    System Preferences > Network > Wi-Fi or Ethernet (depending on how you connect this Mac to the network) > Advanced > TCP/IP tab > Configure IPv6

  3. Do you use any type of software firewall or anti-virus application on this Mac?

1. DHCP

2. Automatic

3. No


Is it possible the printer just went bad ? I haven't tried connecting it to my MacPro directly because that really wouldn't solve the problem, I need to print wirelessly from the MacPro, MacBook Pro, and my iPhone.
