I have a mesh network of 3 Deco X55 Pro and 2 Deco X55. I need to use GlobalProtect VPN for accessing my work network from home. For the last year this has worked fine. However, starting two weeks ago when I launch GlobalProtect my laptop loses all internet connection and must be rebooted to regain network access. This only happens on my home TP-Link network; GlobalProtect works fine on networks either at home or on business trips.

Has something changed in the TP-Link firmware/software to cause this change? I have to get GlobalProtect VPN working again for my job.

I don't know if it is related, but I now see exclamation marks next to all except the main Deco (which acts as a router) and the error message asks about channel Width for 5 GHz: 160 MHz or 80 MHz?

Thanks for your help!
