I have a new Sony Vaio laptop with Windows 7 and I am having problems playing videos fron Youtube, Huhu etc. with a wireless connection. When I connect to my router with an ethernet cable the videos play smoothly. When I try to play videos with a wireless connection they stop and wait endlessly for buffering . I have another laptop that plays videos smoothly using the same wireless router so I don't think the wireless signal is the problem. When I first got thes Sony videos played smoothly so maybe something I installed is causing the problem. Do you have any thoughts on what the problem may be or how to fix it?
