Blinking blue WiFi light

[Kathy81]

My Hp 3730 printer use to print fine but have just had a new router it has 4G on it my other I assume was 3G but my printer won’t print. I have tried switching on and off also the printer but still the blue light is flashing.  Can any one help I am not very technical I am printing from my mini I pad.

Replacing/reconnecting/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.

* Wireless printers only connect to the 2.4G band in your router.  The router must have the 2.4G SSID band enabled with a different SSID name than your 5.0G SSID band in your router.

* 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. 

* 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 it works, it works.  If it doesn’t… 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.

Thank you for your  help but unfortunately  the information you have given me is to complex for me to understand. Originally with my previous router which was the same make  I had no problems connecting all I had to do was check on my mini I pad that my printer was in the list and then I just pressed print and it worked nothing technical for me to do so I will have to show your message to my son when I see him.

I don’t use a computer.

Thanking you once again.

OK, here is your User Guide you need to download and read.  You need to connect your printer to your router so the light is solid blue.

You can do this via WPS method.  If that does not work, you will need your Printers USB cable to connect your printer to your router.
