Deskjet2752E keeps going offline

[duffergary]

My printer status with a wireless connection to my windows 11 laptop shows "offline" every morning. I can get it going again by unplugging the printer, then plugging it back in and let it reconnect to my att router, but the next morning, it is in an offline status again. I have tried deleting the printer and re-installing it, but no help. This all started after I installed a new ATT router, model BGW320.

There is a very good explanation of this problem here

I have the same problem with a BGW210 and a Canon TS702 I use to have.  I had to reach over and press the online button to turn it on. 

My cm1415 is hardwired ethernet and has a static (reserved) IP address.  It also has a TCP port.  Both those solutions are mentioned in that URL above.

Log into the modem or router and change the SSID (names) of each band so the names are different. Create a numeric password identical for each band to simplify login. If you must use alphanumeric characters then do not use any from this set: ilL1oO0D8B5S as they are easily mixed up depending on the font used. Be sure to run the application (if any) that finds the best channel for each band. Your ISP should be able to do all of this for you if you need help.

When logged into the modem,  in the modems connection list, look for the printer and assign its IP address as static or reserved.  The printer may not be identified by name.   You may need to look at your 2752 network report, make a note of the MAC ID, and find that MAC ID in the modem's device list. AT&T cannot do this for you as tech support wont know the printers ID.
