ATT Router - Wifi Printer connection issues

I appreciate input from other customers. But, I was looking to hear back from ATT Help Desk with their official SOP on what needs to be done so the printer doesnt drop after 1 job

My bad. I thought ATT occasionally posted their official SOP/stance to a persistent problem on this forum.

I think the bridge mode might work. But, I suspect something on ATT's router is blocking the printer/2.4GHz connection.

Which is why I decided to bypass the ATT router all together and hook up a seperate router (my old router) just for the printer. The printer does have a Wifi Direct option. But, that option seems not very functional either.

If you have another router connected to the gateway, and the gateway is not in bridge mode or passthrough you could develop issues like a double NAT which can cause problems. I would strongly recommend that you disable the WiFi functions of the AT&T gateway and just use the Netgear. AT&T's WiFi on their gateways appears to not be very robust. WiFi Direct may work but there are issues with that as well, not necessarily related to AT&T.

I use a Netgear Mesh WiFi system with my own modem (don't have AT&T as my ISP) and it works great.

Plan/goal is to make the ATT router functional enough for the printer. I dont want to disable the ATT wifi and connect everything to the Netgear, primarily because I notice significantly lower speeds on Netgear router than ATT router (test was performed on Speedtest.net)

Thanks for responding

Using two routers with both of them "active" is not a good practice and will affect speeds/functionality. We've made suggestions on how to properly configure your setup but if you choose not to follow our advice, then you'll just have to work with AT&T Support, clearly explain your setup, and see what they have to say. I doubt very seriously if there is a firmware push that will allow AT&T's gateway to work successfully with another connected router if not in bridge mode.
