Changed MAC filtering and accidentally blocked all my devices

[Brizz76]

I had problems printing,  so added my printer's MAC address to the Vodafone settings, but, in error, appear to have blocked all my devices. I cannot connect to WIFI on any laptop/phone and can't seem to get my laptop to connect to the router using an Ethernet. Help!

You will need to factory reset the router by holding in the reset button for at least 10 seconds.

There really should be no need to add MAC addresses to the router.

You legend! That worked. Thanks so much.
