Did scan to Diskstation stop connecting with firmware upgrade CLP1CN1516AR

Question

I use my HP 8600 N911g almost daily to scan to LAN network attached storage, in this case a Diskstation. As of today I cannot scan to the Diskatation any more, it just will not connect. I have tried powering off in turn the printer, the router, the diskstation, letting each sit for 1 or more minutes before restarting, to no avail. I can print from my laptop to the printer, i can ping it via IP address and computername, I can open up its web interface and test the network locations - four are defined on the Diskstation, none of them connect. I created a new definition of an existing folder on the Diskstation and tested that, it also could not connect. From my laptop (Windows 7 SP1 64) I can access the Diskstation folders fine through both Windows Explorer and a command line interface. HP diagnostic tools on my laptop all run fine except for the scan test, which pulls in both sheets of paper from the ADF tray but the second sheet does not quite get ejected and the test locked up my printer; cancel and power button did nothing so I had to unplug it. I noticed yesterday that my printer said it was downloading an upgrade but eventually it aborted. Today I ran HP 8600 tools and it said I was up to date. It reported firmware version CLP1CN1516AR, which I understand was released 7/20/15. Could this upgrade be the problem? My printer is connected via ethernet to a LinkSys router that is bridged wirelessly to  a Verizon FiOS ActionTec router to which the Diskstation is ethernet attached. This system has been in place for a year or so. My laptop, bridged router and printer are all within 3 feet of each other, the ActionTec is 30' away through two walls, my latop rates the ActionTec 4/5 bars in Windows icon or -59 dBm from  Xirrus WiFi Inspector, from near to the printer. Vey frustrating. Any ideas, please?

I was called by HP Support, they reached me Friday just as I was about to leave to go on vacation for two weeks. They had read this thread and knew it was more than just me. They acknowledged a problem and assigned me a case number but closed my ticket, I need to call them when I am back on the 24th August so we can work to find a solution. They will open a new ticket then.
I hope HP will contact you and open a ticket for you and resolve the problem and issue a new firmware upgrade including the fix so that I can try it when I return, but that might be a stretch as presumably it goes through some QA testing before they release it. At least they should start working on it with your help.
Please keep us posted on any developments.
For a workaround I enabled scan to computer and email scan. I tried webscan interface and it scans but when finished it says click the save button to save but there is no save button, the two scan and cancel buttons remain unchanged from before initiating the scan. I tried both of those and they do what they say they do and don't save. I can see a preview mini image of the page and if I hover over it it presents a series of icons including a diskette but when I click that I can go through the motions of saving but the file is empty. The email scan is easiest to use, I send to myself and it takes a few minutes after scanning to appear in my inbox and sent folder. From there I can download to NAS or forward as an email. But compared to scan to network it is much slower and more labor intensive.
Good luck, both of you (pcni & greylisted).
