This si a similar thread to one posted by another user a couple of days ago. I try to boot any game and i get disconnected. Then I tried viewing the marketplace to see what was on sale and after it'd search for a long time it'd come up with No Items listed. I try to access thr Sky player and i get kicked from Xbox LIve. I can see my friends and access my messages just fine. I performed tests, some went fine, some failed at Internet, some failed at connecting to Xbox Live. I did multiple tests, rebooted modem on numerous occasions, disconnecting network connections, etc. I contacted Xbox support but nothing could be done for me. Any advice on what to do would be much appreciated, pulling my hair out at the moment.
