Problems on connecting my Officejet 5230 via WiFi to the router

[Simone_Boschi]

Suddenly my printer went off line from my wifi network. I try to connect again with commands on printer display, but it can't find any wireless net. I try with another router and it happens same thing.

Maybe is the printer failured?

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.

Thanks very much for reply. I tried all you suggest, but it doesn't function again... My printer has touch display and when I start "Wireless Setup Wizard", it doesn't find any wifi network, even if there are some. I tried also WPS method, but nothing to do.

I start to fear that it is faulty the wifi module of printer.

Any further advice?

When you reset the printer back to Network Defaults, did you check the status of the Wireless Radio to verify it was on?  Please download and read your User Guide for this info.

Solved! I reset all to Default, not only Network data, and restart from the beginning. Then I had some troubles to reconnect Instant Ink at the printer, but after some trying I suceeded in it.
Thanks for your help, better then HP support!
