@Irina4 reboot your Sky hub by disconnecting ghe power for 10 seconds which will probally clear tge issue. If it doesnt reset the hub which on the black versions is dine by pressing in and holding the reset pin until the power led flashes. On the new white hub press and hold in the wps button, which also acts as the reset pin, for 15 seconds.
When the hub restarts it will be back to the settings on its label. If that works thinkmabout who has nbenn fiddling with the settings and maybe change thecadmin password to stop it happening again.
