About a week ago my xbox started acting up internet wise, the updates were going slower, the dashboard wouldn't load certain things, etc. So I take a look at my internet in network settings and the only difference is the signal is bouncing from 1-3 bars, where normally i get 3-4. I've also tried downloading demos and other content and the downloads just keep freezing (not stopping, but absolutely freezing). My internet has been working fine on all my other devices in my house but my xbox just seems to be having a heart attack here, can someone please help. Also i have a wireless connection.
