Invalid WPA Passphrase

[sballer]

Cable company replaced wifi modem.  Printer recognizes the network name but not the password.  Was told that for all devices to disconnect the network and then reconnect it.  Did this for all iphones, ipads, and laptops and everything works.  I can not figure out how to disconnect the network from the printer. Have tried everything that I can think of and nothing is working.

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 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.

Thank you for all of your suggestions.  I spent all day yesterday on the phone with HP support and Spectrum support.  Everything you suggested was tried and nothing worked.  The modem/router is a Technicolor TC8717T.  It was suggested by HP that an ARRIS model might be more compatible.  We have a bundle package with Spectrum so our phone lines are connected to the modem/router.  I hate to go spend money on a new router when I am already paying Spectrum for the modem/router but if thats the only solution then I guess that is what I will have to do.

Let's check.

In the router temporarily turn off and disable all security.  Now try to connect to your 2.4G SSID with no password.  Are you successful?

If yes go back and add WPA2-AES with password and try again.  Status now?

I disabled the security and was able to connect the printer to the network without a password. 

I tried printing a document from my laptop and nothing printed.  I tried printing a document from my iphone and it did print.

I then set the network back to the original settings with a password.  The printer recognizes the network but still says invalid wpa passphrase.

So my original problem is still there plus I have a new problem since the laptop didn't print anything.  If I plug the laptop into the printer with a USB cord it works. 

Thanks for your suggestion.

Looks like your Gateway is the issue.  Like I said they are terrible for wireless connectivity.

You could try setting the Gateway to WPA only to see if that works.

Best thing to do is what I said.  Put that Gateway in full bridge mode and buy your own high quality router that you control and connect up.  Good luck.

Thanks again for all of your suggestions. 

I went to my cable company and switched the Technicolor modem to an Arris modem.  Came home, plugged it in and everything works now including the printer.

Yay!!!
