Problem solved with a new router. Here's what I did:
- Disabled the wireless in the 5268AC and connected my new routers to it (Asus RT-AC5300)
- Configured the router, pretty easy
Wireless printing is now fully restored, clearly it was a compatibility b/w the built-in router of the 5268AC and the printer. Didn't need to go through any of the 14 steps listed above.

Yes, thank you. Dealing with AT&T and getting a straight answer has been the challenging part of this: from the gateway not having the ability of working in bridge mode, to a long list of things that needed to be done, and finally all I had to do was turn the wifi off (2 minutes).

there is new firmware released, you may want to see these details on HP.com, under product page software /firmware download page,
HP Color LaserJet Pro M377 and M477 MFP Series Firmware Enhancements and Fix List for date code 20160331
- Contains all previous fixes and enhancements.
- Fixed an issue whereby wireless connectivity between the printer and wireless access point is typically lost within 5 minutes of connecting to the wireless access point. Other symptoms specific to this issue are as follows. Checking the wireless connectivity on the LaserJet Pro control panel indicates the printer is still connected to the access point but the printer does not respond to pings and the printer’s embedded web server cannot be accessed. Issue is seen with some DSL modem/wireless router combinations provided by Internet Service Providers that include the HomePNA feature. Models include but may not be limited to, Home Hub 2000, AT and T 5268AC (Uverse), CenturyLink 2100T and CenturyLink 2000T.

To my astonishment, I think I have an idea what causes this problem. AT&T just installed a replacement Uverse modem 5268AC, and now my laptop won't talk to my wireless M477. GRRR! Last night an HP tech wondered if I have two broadband channels on the modem. There are two separate lights for Broadband 1 and 2, so I thought maybe yes. The tech said maybe the computer is one one channel and the printer connects to the other, and I ought to check with AT&T about the modem. Then I read somewhere that to control the modem you browse to 192.168.1.254. Well, I found there aren't two channels, but in the WiFi settings there are two signals, 5Ghz and 2.4Ghz. Both have the same name and password. I also found that some of my devices use the slower signal and some the faster. So I'm thinking that I can change the name for one of the signals, and then I can tell which signal each device uses, and I can make sure my printer and computer connect to the same signal. Now, I guess from AT&T's point of view there's no reason to separate the two WiFi channels (if that's the right term) since they just want to make sure you can connect a device to the Internet through the modem. But for the sake of home networking, we probably need all devices on the same signal. I'm sure some readers of this forum know much more about the networking than I do, but maybe this will point someone in the right direction. Thanks to all who share their wisdom!

Well you are never to have the same SSID name for the 2.4 and the 5 Ghz bands. Because you don't know what you are connected too. You can have the printer on the 2.4 band and devices on the 2.4 and 5 band will be able to see and talk to the printer. It's the IP that is important here. All devices are most likely on 192.168.1.2 through 192.168.1.254.
Like I said, don't care about the which band.

Update the firmware on both the router and your printer.
For many weeks and countless troubleshooting hours I had tried everything you mentioned and much much more, and ultimately couldn't find a solution so I finally gave up and connected the printer directly via the USB port and moved on. A few months ago I received a notification to update the firmware on my device (honestly I don't remember if it was the AT&T Gateway or my M477 printer), but in the update notes this specific problem was noted as fixed! I updated the firmware and voila, the issue was resolved. After many months of denying the issue existed, it seems it was finally fixed.
