Dual band or not?

Is the BGW 210 a dual band router? Unable to connect to smart plugs that require 2.4ghz

It is, but AT&T combines the two bands into one SSID. 

To separate the bands, go to, then go to the Home Network tab, then to Wi-Fi then click the Advanced Options link near the upper left section of the page.  Go down to the 5GHz section and find the Network Name (SSID) box.  Just add a -5 to the end of the existing name.  Ignore the end of the world warning when it comes up.  Scroll down to the bottom and click Save.

At some point during this you'll be asked for the Access Code, which is on a label on the gateway.

Then power off the gateway, power it back on and when it's up and ready, you'll need to manually go to any device that should be on 5GHz and manually change them to point to the new -5 SSID.
