I spent an 1hour and a half with my mom on google meet with screen sharing trying to make it work again... Are you guys pushing updates in the routers?
It worked well for a couple of month. Last time i had to use it was early 2020 or late 2019.
tried disabling the firewall did not work. the setting for the port forwarding is still there, but the ports never opens. Do you have any solution? This is terrible. Covid19 prevents me to go to her home. This is very annoying
