Mine was fine for a good couple of weeks, but I started notice issues as time went on. Some apps were all of a sudden very laggy, and then I had endless WiFi issues, which is eventually when things snowballed as I was trying to get it back online, restarting router and CPE numerous times, and of course the media player too. Had no issues with other WiFi devices, was just the media player that was battling to find and hold WiFi connection, with the router a few metres away and in decent line of sight. Was most likely just unlucky, but not willing to risk doing the upgrades that don't really gain you anything to begin with...
