Since getting xb7 2 weeks ago, couldn’t get lifx bulbs or printer connected. Cameras kept dropping connection on wifi. Fixed it... 2.4 Wifi mode was on g/n/ax Switch it to g/n, lifx bulbs & printer connected right away. ax is Wifi 6. Dont know if there an issues with the xb7s wifi 6 or if the bulbs and printer need new firmware updates to be compatible. Either way I solved my issue. If you set up your XB7, with the xFi app, you wont be able to change these settings. I went in and changed them and then activated xb7 through xfinity.com/activate, so i could go back in change them, they aren’t greyed out. Xfinity needs to stop pushing mesh mode and allow everyone to change the mode settings, otherwise people will continue to complain & contact customer service & no one will know how to figure it out. Let someone know
