Update (6/23/12): I found out what the problem was. It seems that an imperfect connection can keep you from all you wish to achieve. Don't think it's a simple issue because I got damned lucky, i contacted my "router provider" (cisco) which is different than the internet provider (Time Warner Cable)btw. I'm having NAT type issues, I got them partially resolved as my NAT type is now moderate instead of strict. However, the erratic speed of my connection is also an issue, I'm upstairs and have been told that the difference of metals in the walls between rooms could be a determining factor. At this point i have to assume thats the problem with me using a wireless connection, i'm not done though.
While that seems to be the reason why my wireless does what it wants that doesn't give me an answer to my problem of fixing it. Cisco had at the time provided me with a list of possible ways to staighten out my connection, most of which seemed to have been tried instinctively to no avail. Unplugging your router, turning off everything in the house that uses the net wirelessly, these things have all been tried before but I never got the chance to do these things while having my 360 turned off or after Cisco fooled around with my NAT settings as was initially instructed. I'm still not sure if doing that fixed the problem as my wireless connection works fairly randomly but after "doing absolutely ALL I could" my connection coincidentally upped it's game slightly. Though only enough that I can barely join friends parties online i previously couldn't (the day before) and Halo Waypoint showed my Reach character which had been visible AND invisible throughout this experience. The Waypoint stats and Reach character WAS visible when I first noticed I hadn't unlocked the Military Police Helm after beating Reach on Legendary months ago which has me concluding that this is a weird internet/router-related issue. Thanks members of the 343 Industries Forum for all for your support and I hope for the sake of 343 that no one has a weird unexplained internet/router issue in the future
