Why is my internet so slow?

[MikaSch]

4 devices ( 2 Computers, one is connected and the other is off of WiFi, a PS3, and one laptop ) and we don't know how many smartphones etc. all running off of a 19 Mb pipeline, so definitely it is going to get slow.

You should also take into account that in your area or neighborhood there might be many people who got on the internet recently, with the same company. So this also divides the total bandwidth (not the 19Mb that you get) in your area.

It is also possible that you are still using a Docis 2.0 Modem instead of the latest Docsis 3.0 modem. Further on you should check whether you are using a Wireless G adapter instead of the latest Wireless 802.11N or Wireless 802.11AC adapter in the computer with WiFi.
