Haven't done it in while..
But it should be in the settings..
Test connection I think is what it says..
Just done that and everything's fine. I've got an 802.11n wireless signal as well, which is supposed to be the best one available currently. I'll pick up a cable to make it a wired connection for the future, just in case.
It's still doing it, it just skipped the end of the Taker match, so one minute Bray was about to finish him, then suddenly it jumps and Taker's performing the Tombstone. It did the same during the Rock/Rousey section, it kept jumping bits of dialogue so you couldn't follow what was going on properly.
Now it's just frozen completely.
