Ever since I switched to the XFi router (TG3482G). My PlayStation is unable to maintain a proper connection nor is it highspeed in a way. I average about 80mbs download with upto 5mbs uploads. Though I have a 400mbs line or as of today a 1000mbs line. All other devices work with max speeds except for the PlayStation.
I’ve even had technicians here to pull new lines to the house with no luck.
