8600 inkjet will not connect to wifi error code is No filtering fail.

[MTankersley]

My HP 8600 printer worked great with old router but does not connect with new, TMobile router.  Can only print from 1 of 2 computers via the ethernet cable.  The error message is No Filter - Fail.  However T Mobile tech support said several times the filter is off.  Any suggestions?

Hi @MTankersley,

Welcome to the HP Support Community

I understand you are getting an error message No Filter - Fail on your HP officejet 8600 Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• Please make sure your router firmware is up to date

While you respond to that, Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle
