Since you didn't reveal details about your connection (cable, dsl), modem make, model, firmware version, WIFI router make, model, firmware, settings and details such as that PLUS there was no question in your post, was there a question?
I have two computers in my house and my connection speed is really slow. I assumed it was my computers, but I then bought a 3rd new computer and the same glitchy connections still happens.
note: You can't notice the slow connection unless less your downloading something or trying to watch a video on the internet (youtube, myspace, hulu, etc...) I say glitchy beacause the videos will work for 5 secs than start skipping. Its increadbly annoying. I can never watch any videos.
