I have an Xbox 360 Slim and i have tried wireless and wired connections with no luck. Every 15-20 minutes I get disconnected from xbox LIVE. I have tried restarting router, modem, and console, with no luck. Also, i've enabled DMZ, UPnP, and tried port forwarding but when i open the XBL ports all my internet goes down including my wi-fi until i close the ports again. I have the Linksys EA2700 router, and the Cisco SPA2102 modem. If as soon as i turn on my Xbox, and go to netflix , i can watch movies and shows for hours but if i play online games before watching anything on netflix i get disconnected just the same on netflix. It's very odd and I've tried everything, any help is appreciated.
