My internet has been lagging very frequently for the past 2 weeks and often it would completely crash. I use it at night for homework, and that's the time everyone is sleeping, so I don't think it is because its being shared by multiple computers. It doesn't only lag on my laptop, its like this with anyone who uses the connection. We already called for tech support, but I want to understand what the problem may be.How to know where internet lag is coming from?
Make sure your connection is secure and/or change your WEP key. Chances are sense you said it's on all devices that it may be some one running massive downloads on your network.
It could also be ICMP flooding, ARP cache poisoning, or equivalent.

On the software end, you could simply disconnect or shutdown ALL PCs in the house, then connect from a mobile device and do a lag test. That would tell you if it's one of the computers vs. your network. Pingtest.net is a great way to test.
If it is a computer on your network, isolate it and run multiple security tools. (MBAM, SuperAntiSpyware, all the standard) It could be a virus sending spam and causing lag.
Hope these ideas help.
