HP C510A eStation Printer - Zeen: Not Connected - Can No Longer Connect To My Wireless Network

Question

Up until a couple of weeks ago, my C510A was working well.  Every so often the wireless sync would fail and I would have to resync the Zeen tablet, or unplug/replug back in the printer to regain sync, but now...  Nothing!
My Firmware is: ZEP1CN1130AR
Printer IP: 192.168.1.74
Zeen IP: Not Connected
SSID: Visible
Mac Filtering: None
Security: WPA/WPA2 PSK
Signal Strength 3-4 Bars (I can move closer to the router and watch the bars increase, and move further away and see them decrease.  So the wireless radio is on and functioning within the Zeen!)
The Zeen cannot connect to my network and is never given an IP address, so I can't set the printer up with a static IP address.  It just keeps trying to sync with my network and failing.  Over, and over, and over, and over again...  I have reset the Zeen to factory using the Power On/Volume Up combo.  I have uninstalled my HP printing software suite, redownloaded the latest version of the entire suite from the HP Support site, and have installed the drivers/printer both wirelessly and via a USB connection.  I have powered down my wireless access point and powered it back up to see if that helps, but nothing does.
uVerse Cisco 2Wire i3812V Gateway/Router
Netgear WNDR3700-V1 configured as a wireless access point (Thanks to the crappy 2Wire POS above.)
I have numerous laptops (Mac and Windows), a Mac Mini, 3 tablets (WebOS, IOS, and Android), IOS and Win8 mobile phones, a Roku 2 XS, various TV's and Blu-Ray players, a Wii, and this malfunctioning HP printer connected to my network via 802.11 DB wireless AND a wired gigabit network.  I run a Plex Media Server on the Mac Mini which is my HTPC for our home.  The printer was working fine in this setup until a couple of weeks ago.
From reading the many Zeen threads here, and on other forums, it's obvious that there is some sort of ongoing connectivity issue with the Zeen tablet on this printer.  HP has been conspicuously silent on the issue, and there is precious little to go on in the HP Knowledgebase, or in replies on this forum.  I've suffered through being hung up on, as well as trying to explain my problem to tech support reps who both do not speak English very well at all, and are unable to grasp concepts and analogies in English.  
My frustration level is HIGH at this point.  My printer is out of warranty, and if there is a hardware issue with the printer then I fully expect to have to make the decision as to whether it's worth repairing or not, but I do FULLY expect to be able to talk to someone in technical support who speaks English about the issue and try to diagnose and fix the problem if it's just a software/networking/configuration issue at NO CHARGE, just like I do with every other product that I own!
So I'm coming here to try and find an answer to my problem before I reach the point, and it's very close right now, of totally severing ties with HP, Compaq, and all the rest of their subsidiaries both here at home, and at the company I manage (where I pretty much make all of the hardware decisions).  This just isn't the way to treat your customers.
Any help and suggestions are greatly appreciated.

Answer 1

Hi,
When Zeen's battery level goes below 5 %; it tends to Reset to Default where it looses all the connections and sync to the printer or router.
So its very important to make sure that Zeen's battery does not go to low. To avoid this I would suggest to charge Zeen regularly.
You may try the steps below as of now and check the results.
We need to Factory Reset the Zeen making sure it is connected (Docked) on the C510a printer.
Once it is docked try the steps below:-

Open the above link; and then perform the Factory Reset as shown in Solution Two.
Once completed try connecting to Wireless and check the results.
though I am an HP employee, I am speaking for myself and not for HP.
