My HP OfficeJet Pro 8600 won't connect to my wireless router

This is bizarre.  I have had my HP OfficeJet Pro 8600 for about 6 months.  It has generally worked fine, and we have used it wirelessly only.  But now it refuses to connect to the router.  It can FIND the router, and it can find other networks in the area, but it won't connect to the router.  I ran the Wireless Network Test, and the results say:

 

Wireless On - Pass // Wireless Working - Pass //

...

Network Name (SSID) found - Pass //  Wireless Networks Detected - 9

Printer Settings Consistent with Wireless Router Settings - Pass / No Filtering - FAIL //

 

So it recommends solution as follows: "1 If MAC Address filtering is enabled, and you would like to keep it enabled, you must add the Mac address of your printer to the list of permitted devices for your router before continuing."

 

Except, guess what, I don't have MAC Address filtering enabled.  I wouldn't know how to do that, much less check for it.

 

Also, before today, this was never a problem.  HELP!

 

Thanks....

 

***********

 

If you are interested, here's more detail and background.  

 

Before today, the only problem we have had is that frequently our Apple laptop (OS X 10.6) has trouble connecting to the printer.  This has been odd because the printer is connected to the network, and so is the laptop, but the laptop can't find the printer - it thinks the printer is "offline" (even though it's not).  Usually, if I wait a while, it will find the printer, and it will resolve itself work fine.  If not, we sometimes have found that it can fix itself if you restart the laptop -- restarting the printer does not make a difference.   In fact, I did exactly that today, and it resolved itself.  And I printed.  Fine, right?

 

But then I wanted to do more printing, and the problem of the laptop not finding the printer came up again, so I decided to really "get to the bottom of this."  I don't remember exactly what I did, but somehow I was persuaded by the online help, that the correct solution would be to go into my System Preferences / Print and Fax, and click on the "-", which de-installs the printer, with the idea of re-installing the printer.  But then when I tried to re-install the printer, it could not find the printer.  Ugh!  Wierdly, it found an 8600 Scanner, but not an 8600 printers.  After installing and de-installing the 8600 scanner a few times, I eventually deinstalled everything, and I decided to start from scratch.  I got my HP disk, and installed all the software again from the beginning (even though it was already there), and then it looked for my printer, but couldn't find it.  So then I got a USB cord, and plugged that in.

 

So, now I have a situation where I do have a working printer via the USB cord, but no wireless connection at all.  In particular, since the Office Jet Pro 8600 won't connect to the router, I don't know what else to do.  My Apple MacBook pro is 2 feet away from the printer, and it is connected to the router just fine (as is my blackberry), and I have never before had a problem connecting to the wireless router by the printer.

 

Any suggestions?

Re: My HP OfficeJet Pro 8600 won't connect to my wireless router

There are two things that can trip the mac filtering test to fail:  actual MAC address filtering setup (sounds like this is not the case) and using wireless channel 6 or automatic for wireless channel in the wireless network settings (in the router).  Since it does show failed for MAC filtering and you do not use this option, try changing the wireless channel in the router to 1 or 11.  Those two channels provide the best compatibility with printers due to less interference.  Almost everything defaults to auto or 6 for the channel and this causes a lot of interference.  This change should not affect anything at all.  To do this, you may need to contact the router manufacturer as the process differs from router to router.

 

What brand and model is the router?

 

Has anything in the network settings changed at all?

 

What version is the Mac OS X?  There may be additional steps to take as it sounds like there are two separate issues involved and this could be revisited later.

Re: My HP OfficeJet Pro 8600 won't connect to my wireless router

Hi - Thanks for the reply.  So, after it was on for a while (overnight), it magically corrected itself - almost!  The screen indicated that the printer is now connected to the router.  And I know it is now actually connected to the Router, because I sent an email message via ePrint, and it printed out fine.  

 

However, we're now back to the original problem, which I noted in my original posting, where the Apple MacBook Laptop thinks the printer is "offline".  :-(  I have tried plugging it in via the USB port, and then it works just fine, but for some reason, when both the MacBook and the Printer are going through the Router wirelessly, it doesn't work.  (The MacBook has no problem at all using the router to put stuff back and forth via the internet - I am using the router right now to post this message).

 

So, in short, the MacBook can talk to the router wirelessly, and the Printer can talk to the Router wirelessly, but when the Macbook tries to talk to the Printer wirelessly through the router, the MacBook thinks the printer is "offline."  This is Mac OS X version 10.6.8.

 

Please advise.

 

Thanks,

 

David

That does indicate the issue is isolated to the Mac printing system since ePrint does function on the printer.

 

Reset the printing system as outlined in this document from Apple.  This will remove any printer installed, so all printing devices will need to be installed.

 

Next, install this HP driver package from Apple.

 

Once those two steps are done, go to Apple>System Preferences>Print and Scan.  Add the printer by clicking on the + sign.  This should get this working on the Mac.

 

Let me know what happens.

Try rebooting your router.

 

Saw a post on a different forum - HP sent out a firmware update and that user had the same problem as you (and me).  Solution worked for me.
