I have been having this problem with where it will allow external connections for about 30 minutes but then doesn't allow any? I have port forwarded and all that. I turned it on last night and I wouldn't allow external connections but I came home today and turned it on and it would for 30 minutes but then it stopped so i restarted it and shut it down and booted up again but it still wouldn't allow them again?
My ISP is TalkTalk
