Hi @Mick161,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand how frustrating it can be when your printer works perfectly on one network but refuses to connect after installing a new modem. I’m here to help you get your HP DeskJet 3630 back online.

When a new router or modem is installed, the printer must be reconnected to the new wireless network since it still attempts to communicate with the previous one. This is a common situation and can usually be resolved with a quick wireless reset and setup.

Please try the following steps:

1. Restore Wireless Setup Mode
Press and hold the Cancel (X) button and the Wireless button together for about 5 seconds until the blue light begins blinking. This places the printer back into setup mode.
 

2. Reconnect the Printer to Wi-Fi

• On your computer or mobile device, download or open the HP App – For HP Printers, Laptops, and Tech Accessories | HP® Official Site.
• Select “Set up a new printer” and follow the on-screen instructions to connect the printer to your new AT&T network.
   

3. Check Network Compatibility
Ensure your router is broadcasting a 2.4 GHz network, as the HP DeskJet 3630 does not support 5 GHz-only connections. If your router combines both bands under one name, you may need to enable the 2.4 GHz band separately in the router settings.

I hope this helps.

Take care and have an amazing day!
