I posted this over in the MCC forums to help people, but it doesn’t actually apply to me… The game has been working great for me and the updates you’ve applied have immensely improved my online gaming experience. This is just based off my limited I.T. education and experience, combined with research on the subject that may help you guys continue to refine and fix the MCC. Keep up the great work!!! (BTW Feel free to message me directly if you think I’m off with any of these suggestions… Ideally, I’d like to be giving out good information to people to help them resolve their issues…)
"If you’re not experiencing networking and/or connection issues then this does not apply to you… But for people still unable to play in online matches take a minute to read this!!
Remember to enable Open NAT Settings… But keep in mind that this may not be the root cause of your issues. Moderate and Strict NAT Settings narrow the search for people that you can play with. So if you have an Open NAT, than you’ve effectively expanded your search for players. This fix helps out a lot of people that are experiencing difficulties finding players, but isn’t the only solution that will fix every networking issue.
Still not fixing your issue?? Also remember that latency makes all the difference in online play for the MCC… In laymans terms, the best way to describe what latency is (and I know anyone with an I.T. background is going to cringe at this comparison) is like sonar waves… Imagine how sonar works- a signal gets sent out and has to return back to the source. You can have an average, or even above-average internet download speed and still suffer from high latency that is really only noticeable with most FPS games. This means that games like Minecraft or Forza may confuse you into thinking that you don’t have a network issue which may also cause you to believe that the developer of a FPS game may have sold you a faulty game… When in fact you should really be pointing fingers at your Internet Service Provider (Satellite/DSL ISP’s are notoriously HORRIBLE for advertising high speeds, while brushing high latency under the rug with their customers). You may not realize this could be an issue because some games don’t need low latency rates (sub 50) in order to afford a good online gaming experience but Halo really, really does… Especially the campaign and H2A Multiplayer. I played four player campaign with someone from Austria a little while back and he tested his connection to discover dreadfully high latency, despite his high Mbps download speed. You can check this out in the settings app under network - test. For more information about latency, read this: Yahoo | Mail, Weather, Search, Politics, News, Finance, Sports & Videos
Sorry for not hyperlinking- I’m on my mobile so there’s not an option… And I know yahoo may not always be the best source for veracity but in this case they have some great, accurate Q and A regarding latency and gaming.
Also make sure you’re not on wireless if you’re experiencing network issues!!! If this applies to you then immediately find a way to switch over from wireless internet to wired. You may not know this but wireless internet severely hampers your internet speeds and can even result in packet-loss.
There may be additional settings on your router that you don’t know about that are affecting your P2P connection. Your ISP that you pay every month is responsible for delivering you working internet so I highly recommend that you call them and demand them to walk you through trouble-shooting methods to ensure you have the proper settings for a proper online gaming experience."
