Hi rubymcqueen,
Thanks for your post and welcome to the forums. It's really great having you on board with us in the Community.
I'm sorry to hear you are having an issue with connecting the printer to your wireless network.
As all the other devices are working, it suggests the issue is with the printer rather than the Hub. There is a great link from goslow that may help you in their post above.
Should that not work, it may be beneficial for you to separate your WiFi bands and then connect the printer to each of these to see which one it connects to best. To do this, follow these steps:
• Access your Hub by navigating to 192.168.0.1
• Login with the default login info (on base of Hub) unless you've already updated it.
• Go to Advanced Settings > Wireless > Security
• Under Wireless Frequency 2.4GHz change the Wifi Network Name (SSID) and the Wifi password (network key).
• Repeat for the Wireless Frequency 5GHz and click on Apply changes.*
* Make sure that both frequencies are named differently and are still identifiable
Come back to us and let us know how things go.
Thanks,
