Every game but WoW gives me packet loss

[Rytox 0]

Hello, I hope you guys can help me. I have been experiencing a weird issue for a little over a week now. But I have finally diagnosed the problem. When I try to play games like Combat Arms, Arma II /OA, BF3 and run a ping test on pingtest.net my ping is steady, and my jitter is fine but the packet loss is ridiculous! I will have a packet loss of 90-100% causing the game to be unplayable. But when I run this test playing WoW I have 0% packet loss, steady ping, and good jitter. I am completely lost on what to do, other than contact my useless ISP that will not know what to do. I am really frustrated by this and am not sure what the cause of this is or what to do. I have been researching for over a week and have no where else to turn.

I really hope I can get some quality responses that will help me.

should check with your ISP, maybe have them refresh your signal can sometimes be on their end, also if you connect through a router can try to reboot that or (and this is what I would do) get rid of the router and direct port into your modem for best quality.

if you are DSL, try reducing packet size from the default 1500 to 1495 and go down by 5 until the packet loss stops.
