You probably need to connect to your new wireless router.

Open the Alexa app.
In the Alexa app, open the left navigation panel and then select Settings.
Select your device and then select Update Wi-Fi. If you're adding a new device to your account, select Set up a new device instead.
On your Echo device, press and hold the Action button for five seconds. The light ring changes to orange, and your mobile device connects to your Echo device. A list of available Wi-Fi networks appear in the app.
Note: The Alexa app may ask you to manually connect your device to your Echo device through your Wi-Fi settings.
Select your Wi-Fi network and enter the network password (if required). If you don't see your Wi-Fi network, scroll down and select Add a Network (for hidden networks) or Rescan.
Optional - Save your Wi-Fi password to Amazon: Any Wi-Fi passwords saved during setup automatically appear when you connect a new Alexa device to the same Wi-Fi network. The password is also remembered if you switch between saved Wi-Fi networks. For more information, go to Saving Your Wi-Fi Passwords to Amazon FAQs.
Optional - Connect to a public network: Enter any required information if you are connecting to a public network that requires a web browser to sign in, like a school or hotel. The information could be a pre-shared password, room number, or just a button to accept conditions for using the network. This information cannot be saved to Amazon. Contact the network owner for more information.
Select Connect. After your device connects to your Wi-Fi network, a confirmation message appears in the app.

How to connect to a Wi-Fi network

• If you selected a secured network a password box will pop up. Enter the required password and then press 'Done'.

When you're connected to a wireless network, the wedge-shaped Wi-Fi connected icon appears in the status bar and shows you the signal strength - indicated by the number of bands that light up.
Unless you have wiped your phone, you won't be required to re-enter Wi-Fi details again as your handset should remember them.
How to connect to hidden networksA Wi-Fi network might be hidden, which means the network name isn't broadcasted. In this case, it won't appear in the list of available networks on the Wi-Fi Settings screen and a notification won't appear when the network is in range.
To connect to a hidden Wi-Fi network when it's in range, you'll need to enter the network name and password. Remember that the network name and password are case sensitive.

you need to setup airprint on the printer, see:

http://www.usa.canon.com/CUSA/assets/app/pdf/airprint/How_to_Print_Using_Apple_AirPrint.pdf

I suggest you reset the Lexmark Z2420 wireless network adapter. To reset, do the following: With the printer on, press and release the power button. The printer will enter power save mode. Now, press and hold the paper feed button. While holding down the paper feed button, press and release the power button. Continue holding the paper feed button for 30 seconds. Release the paper feed button. This will reset the internal network adapter (INA). When the printer has been reset, a solid orange Wi-Fi indicator light should appear. If Wi-Fi light goes back to flashing red, you have not successfully reset the printer. Start the procedure again. Once you have a solid orange Wi-Fi light, reconfigure the printer for wireless connection. Thanks.

Resolution If you know there is a nearby Wi-Fi network, but you are unable to locate it on the Settings > Wi-Fi screen:

• Move closer to the Wi-Fi router or hotspot.
• If you are using a personal Wi-Fi network, verify the Wi-Fi router is connected to power and turned on.
• Wi-Fi networks configured as "closed" or "private" do not broadcast the network name to Wi-Fi devices.
  • Join a "closed" or "private" network by tapping Settings > Wi-Fi > Other and entering the Wi-Fi network name, security, and password.

After joining a Wi-Fi network, if you notice the signal strength is low or intermittent

• Move closer to the Wi-Fi router or hotspot.
• Check for any sources of potential interference.
• Remove any cases or attachments on your device that could interfere with a Wi-Fi signal.

If you are unable to access the Internet while connected

• If you are using a commercial Wi-Fi network that requires a special login or subscription, see this article for more information.
• If you are in a location with multiple Wi-Fi networks, verify that you are selecting the correct network.
• Verify that the Wi-Fi network settings are correct:
  • Tap Settings > Wi-Fi.
  • Locate the Wi-Fi network you are currently using and tap
    

• You can configure network-specific settings, including IP address, DNS, and Search Domain settings.
• Use "Forget this Network" to reset settings for this particular Wi-Fi network, including the password. This is also useful if you identify a network issue and want to prevent the device from automatically using this network in the future.
• Use "Renew Lease" to acquire new IP address, DNS, and Search Domain information from the Wi-Fi network.
• Note: If the Wi-Fi network uses MAC address filtering, you will need to add the MAC address to the access list for the Wi-Fi router. The MAC address for your device is listed as the Wi-Fi Address in Settings > General > About.

If you are still unable to join a Wi-Fi network, or are unable to access the Internet while connected, try the following

• Restart the device
  • Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the power button to turn it back on.
• Reset network settings by selecting Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings, including passwords, VPN, and APN settings.
• iPhone only: If you continue to experience issues, consider turning off Wi-Fi and using the cellular data connection instead of Wi-Fi.

Additional Information If using a Wi-Fi router at home, refer to your user manual/documentation to assist you with some of these suggestions.

• Check the manufacturer's website for your Wi-Fi router for firmware or software updates.
• Verify the Wi-Fi router can broadcast an 802.11b/g signal. If using a 802.11n Wi-Fi router, consult the manual/documentation for how to configure the Wi-Fi router for 802.11b/g compatibility.
• If you are using multiple WEP keys on your Wi-Fi router, try configuring your Wi-Fi router to use only a single WEP key.
• Try or resetting (or turning off and then on again) your Wi-Fi router. Note: If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
• Disable wireless encryption or security on the Wi-Fi router to rule out encryption issues. If this resolves the issue, try using a different encryption or security protocol.

Wi-Fi Protected Setup Button
If you have client devices, such as wireless adapters, that
support Wi-Fi Protected Setup, then you can
use Wi-Fi Protected Setup to automatically
configure wireless security for your wireless
network(s).

To use Wi-Fi Protected Setup, run the Setup
Wizard, or refer to the “Wireless > Basic Wireless
Settings” section of “Chapter 3: Advanced
Configuration".

Wi-Fi Protected Setup LED (Blue/Amber) It
lights up blue when wireless security is
enabled. The LED flashes blue for two
minutes during Wi-Fi Protected Setup.
The LED lights up amber if there is an error
during the Wi‑Fi Protected Setup process. Make
sure the client device supports Wi‑Fi Protected
Setup. Wait until the LED is off, and then try again.
The LED flashes amber when a Wi‑Fi Protected
Setup session is active, and a second session
begins. The Router supports one session at a
time. Wait until the LED is off before starting the
next Wi-Fi Protected Setup session.
