Hi my wi-fi is extremely slow on all the devices. It all started when I received a error message stating that www.wifiext certificate is not to be trusted. I have no idea what that is as I’ve never used it. This message only shows when I’m using the wi-fi.
Yes we are using a netgear extender. It seems the third party net gear has been hacked? As whenever I switch it on, only then I receive this error message and the internet is super slow. My sisters phone is also receiving the same error message so it’s not just my device.therefore I believe it’s been hacked? What can I do about this? I need the extender as it reaches my bedroom.
