wifi band
I have a Inspiron 3780 (Intel(R) Core(TM) i7-8565U CPU @ 1.80GHz 1.99 GHz) and an Epson EcoTank ET3750 printer. The printer is only available for 2.4g wifi band and my laptop is dual band. My ATT Gateway router says the SSID for the 2.4 and 5G are separate. On the laptop, when I connect to the 2.4G SSID and click on the properties for wifi, it says I'm connected to the 5G band, therefore it has trouble connecting to my printer via WiFi. How do I change the settings on the laptop to be connected on the 2.4G band?
My printer has a Direct wifi option that I can connect without a network wifi and when I select that on my laptop, it says it's connected to the 2.4G band.

Hi RichieRich83:
I have an Epson XP-7100 printer and found wireless printing from my Inspiron laptop via the Cisco router provided by my ISP (Shaw Communications Canada) was ridiculously difficult to configure. Creating a wireless connection to this printer is still erratic and I've found that my Epson software is usually unable to detect the printer on my local network unless I power on the printer before my laptop is booted up. When I first installed my Epson software and drivers on my laptop this created two separate printer devices with different names in Win 10 at Settings | Devices | Printers & Scanners (and a second Epson printer device will sometimes re-appear in my Win 10 settings when my Epson software is updated) and I had to open a support ticket with Epson just to figure out which Epson printer device could be safely deleted in my Windows settings.
Regarding your specific question about wireless radio bands, you might want to post your question in the AT&T Internet equipment board at https://forums.att.com/topics/att-internet-equipment/5def8ee330b80f78b6772606. Other users have posted in that forum about wireless connections to peripheral devices that require a 2.4 GHZ radio (see AquaScor's Dec 2018 thread 5 GHz or 2.4 Ghz for one example) and your ideal solution might depend on the exact make and model of your AT&T router.
This might not be relevant to your problem, but the AT&T support article Combine Wi-Fi Network Names has some information on the pros and cons of using a single network name (SSID and password) for both 2.4 and 5 GHz radio bands to take advantage of the band-steering technology included with newer AT&T router models.
