Im having the same problems. Randomly can't sign in to XBOX live, yet other times I get on no problem. Each time I can't sign in, it says I can connect to my network and the internet, but can't sign in to LIVE

Go to your PC, go to my computer, find the device itself and open it. Check if there are any files after you format it. I'd so, delete them manually. After that reformat it to FAT32 by right clicking it and choosing format, not quick format. Take a few extra
seconds to ensure its done right. Afterward, ensure no random files are on it. Stick it in the front USB port and go to settings, memory devices and chose to format your USB device for only Xbox use. If it still is not working after all that, perhaps the thumb
drive is corrupt for Xbox use. Go buy another SanDisk with official Xbox packaging to ensure its 100% compatible. Use the old thumb drive for music and videos you can use in system player when it's formatted to fat32. Just a suggestion.

I can't even sign into xbox live on hughes net...When I turn my console on, it says that an update is required to sign in to xbox live, but it's currently unavailable...I installed the update via flash drive after downloading it on my computer, so I know
that the update stuck, but I can't sign in to xbox live at all...I can download updates and everything else, just can't sign in...so GAY!!!!
