Over the past couple of days I have been getting constant disconnections from games when I try to play. Half the time they won't log in. In some games, they log in but it is completely unplayable. The internet still seems to work (albeit sometimes it seems to also have trouble connecting). I have turned the router on and off multiple times, run the online connection test tool (which says there are no issues).
That seems to fix it. I then turned it back onto modem and wireless mode and it seems better (it has not completely disconnected yet and have played for 20 mins) but the game I am playing has a red warning sign saying there is a network issue (related to latency). According to speed test on google, everything is fine for ping. This is what it was doing before though (speed test was fine but games kept breaking).
