Can someone offer some input? My son has a brand new desktop gaming PC with good specs that is connected wirelessly (he has an internal wireless adapter card.) We also have a new dual band Linksys router that we purchased within the last month with good specs. At least every couple of days - sometimes more frequently - he will be in the middle of playing his online game with friends and Skyping when his internet will lose speed, his game will freeze, and the Skype call will either drop or get very poor. His speed test results show very poor download speeds and ping for at least 1/2 hour or longer before his computer recovers enough to play decently again. In the meantime, I can bring my laptop - which is connected to the same network - into his room and my speed test results are perfectly fine. While this is all happening, his wireless signal stays at 5 bars and doesn't lose connection, and the modem and router lights are fine, not blinking or showing any signs of issues. The ISP (Comcast) has not found any issues with our signal. Can someone give me any idea as to why this might be happening/what to try? It's getting very frustrating. Thanks in advance.
