This problem has just suddenly happened. I can connect to my xbox 360 and talk to friends etc. But when it comes to playing games or sky it just lags really bad now. I have had the same connection for around 18months now, no problems and open connection.
It says open connection on games but i get a red bar so lag is extremely bad.
My laptop, iphones etc have perfect connection to the internet.
Wireless adaptor and ethernet cable both have the same issue.
Have switched off the router many times but has made no difference.
Have done all the open ports stuff and everything.
I know my internet did go off for a couple of hours and to my knowledge is hasn't worked since then, can there be some sort of connection?
Does anyone have any ideas?
