Yes. Works good run a cat 5 cable from the AT&T router to the Orbi main router. Run there app and in a few minutes you have a new wifi signal. Then you want to turn off the WiFi coming from that ATT router. You will need to log into your ATT router and turn off The wifi signal. Att.com explains how to turn off wifi.I do not recommend call ATT for help. I spent 5 hours on the phone with them trying to figure out how to do this prior to buying the system . They were no help. I opened the box and I was up and running in less than 10 minutes.
