Scanning, Faxing & Copying

I have a Laserjet M125nw AIO printer/scanner running wirelessly in concert with Windows 7 64-bit OS and 1Gig internet all in the same small room. I have no issues with the wireless internet on any other device, including tablets, phones, Sonos, etc. But the scanner portion of my BFF HP AIO is no longer working wirelessly.

The printer works just fine wirelessly and the scanner works as long as it is wired to the laptop using the HP-provided USB cable. That was okay once, irritating twice, but unacceptable the third time. You see, HP, I have to unplug the device, move it to a spot near the desk, plug it in to the wall and then to the laptop in order to scan.

To the best of my knowledge, there were no changes or updates to my wireless network nor were there changes or updates to the Windows OS (I do not have Windows Updates set to auto). Several times, I went through the troubleshooting steps listed here: https://support.hp.com/us-en/product/hp-laserjet-pro-mfp-m125-series/5396664/document/c00040499. No joy.

The HP Print and Scan Doctor always returns a red "X" on Windows (WIA) Scan, but all possible solutions to that issue have led down a variety of rabbit holes. The last thing I read on the HP forums was something like (I'm paraphrasing): If DIM doesn't show up in the msconfig list, the HP drivers did not install correctly." Well, I've uninstalled and reinstalled them at least six times and spent some 4-5 hours struggling to git 'er done.

My warranty ran out in February (2017), so HP offers crickets in lieu of verbal support. Okay, I get it, but this is for home use and so does not have heavy demand put upon it. So, the warranty period may have expired, but in terms of usage this magic box still sparkles like new. I'd like some support from HP, please.

Thanks.
