Whenever anyone is using Facebook or Messenger, through apps on their phone - content fails to load and messages fail to send. Connecting to Facebook fails entirely when connecting through web browsers. This has been a recurring problem since we received our router, and only happens when we use our TalkTalk wifi. I have also found out that using a VPN, and connecting to an American IP address allows me to access Facebook. Switching to 4G data is the only other way to access Facebook, how do I solve this problem?
