Why is my internet bad for gaming?

So i have Excede and Wildblue internet with a Cisco E2500 router. I have great Wi-Fi signal and the internet works good on my laptop and iphone and ipod. But when it comes to gaming on my Ps3 i can sign in and watch youtube normally, youtube loads up videos good. But when i try to play Black ops 2 or Mw3 or Injustice, or any other online game, i can't do multiplayer i just can't do it. Why is this? I thought this internet service was supposed to be good?

Confirm your internet speed. What is it?

Check and make sure the router's security is not in mixed mode.

  • Why does my laptop get such bad internet download speed while my Iphone gets 10 times more? My router is downstairs connected to a Windows vista PC. That PC connected with an ethernet cable gets around 90-100Mbs download speed. I did another speed test on my iphone upstairs next to my laptop, and it got 80-90 Mbs. But When I did the speed test on my laptop, it was only 10Mbs down. It's really annoying because it takes like a billion years to open youtube and everything lags.
  • Why does my iPhone still charge for Internet even when I'm not using Internet? So, I recently got a pay monthly plan with my new iPhone 4s. When i'm out and about I'm usually updating my twitter and Facebook account. But, when I'm put my phone down, 3G still says I'm using it and charging me. So do I have to turn it off when i'm finished? Or is there a much easier way?
  • PS Vita vs iPhone, which is better for gaming? I heard that the PS Vita has almost no games, and the few it does have all suck. While the iPhone on the other hand, has possibly thousands of games, some of which are for hardcore gamers and are actually really good. Comparable to the PS3 and Xbox 360.
  • Is this optus internet fast enough for gaming? https://www.optus.com.au/shop/broadband/naked/200-monthtomonth This is the link, it is 200gb a month and 256kbps. I use it for gaming, streaming and downloading movies and games. I don't want high ping or lag when i'm playing games, we usually have 2 computers 3 iphones and an ipad connected at one time. Will i be lagging. I play games on computer like, "Garry's Mod, TF2 and xbox GTA5, COD" etc thanks
