cannot connect online

I have always had this problem..i can get on and after 2 or 3 minutes tops it kicks me out and says network status error.......I can play all day long with a buddy or two in private games don't know what the deal is...this has been this way ever since I
started playing the game a long time ago..so its nothing about me being a bad player or anything I don't have time to be

Known problem with Activision,
support.activision.com/.../Cannot-connect-to-an-online-game has useful information.

I'm using the USB wifi adapter. Sometimes, when I reset my router & modem & unplug/replug the adapter, I get quite a few games in, but eventually it just stops connecting and the same problem occurs again.

Unfortunately I don't have an ethernet cord long enough from my console to my router.

I just ordered one and hopefully will report back with good news.

I can play but its very slow. I cannot play with any friends, it just says "You could not be added to the party queue". Then When I go to war games, find match it says "The Halo 4 servers are not available. Please try again later. Matchmaking has switched
to using default playlist." I played normally earlier today and just now it started doing this.

So i ran an ethernet cord with no luck. Im stumped...

This only happens with Halo 4. I can play other games just fine.

Any other suggestions?
