HP 3630 wifi button blinking as can't find new router

[Suehelen]

We recently got a new wifi router and have managed to print by selecting the HP SET UP option in our mobile wifi settings but the wifi blue light is constantly blinking. I subscribe to instant ink and it constantly says the printer is offline. I have tried resetting the printer by pressing X and wifi button and WPS button on router. Nothing seems to work. How to get the printer to find the new router and override the old one? Any help would be very appreciated.

Replacing/changing your wireless router, try here.

* Reset your printer back to Network Defaults.  Then run the Wireless Setup Wizard to connect.  Both can be accessed from the front panel or computer.  If no front panel for configuration, you must use your Printer USB cable to connect.  You can also try the WPS method if your router/printer supports this only if the Wizard or Printer USB cable is not available.  Read your User Guide for info.
* Set router to a fixed wireless channel like 1, 6 or 11, never ‘auto’.  Try channel 1 first then the others one at a time.  
* Make sure printer and router are at least 5 feet apart.  
* The router must have the 2.4G SSID band enabled with a different name than your 5.0G SSID band in your router.  
* Make sure IPv6 is disabled in the printer.

Make and model of modem and router?

However if you have a Gateway (modem+router) device, all Gateway devices are terrible for wireless connectivity.   If this does not work, suggest you think about putting that gateway device in full bridge mode and install your own high quality router that YOU have full control over.

Thanks. I'll work through your suggestions and see how I get on.
