|He is on youtube and downloading music on mp3 rocket. I do not have a problem with him doing that, it's just when we want to use our computer, we would not like it to act like it is on dial up.|
That's what's eating your bandwidth right there. Downloading any large files will do that.
The wireless router we have is a Beklin. About 4 yrs old, should we look at upgrading it to a newer one?
If it ain't broke, don't fix it.
The issue isn't your router, it's your son's bandwidth hogging that's slowing you down. If it were me, I'd just unplug him while I'm online, and plug him in again when I'm finished. That or limit him to times of day when you're not using it.
I've done both in the past with my kid. He didn't like either very much but I'm the one paying for the internet so he had two choices....live with it or get a job and pay for his own. He lived with it until he moved out.
Ironically, he now has a roommate that downloads constantly and it makes me laugh every time I hear my son complain about how his roomie's bandwidth hogging activities annoy him! LOL
