We definitely hear you loud and clear.
Are you able to fix your issues by switching to a wired connection or using these steps at all?
I do agree with a test, but it's kind of bad make us use wire if you want to play... I guess it should work with wireless.
I don't believe the weird searching behavior has to do with the wireless, but I'll try.
The system actually finds sessions but then it "gives up".
Anyway I'll try with a wire as well.
I've had the same experience with the 8 person matches; system finds a match and the countdown timer starts... then it starts seraching again.
Not sure what the problem is since I can get into the other match types okay. Could it be that ppl are forming parties prior to entering the lobbies?
