Hello,
my wireless router wont allow me to connect to the internet through my xbox but alows me to connect with router its self, i dont understand why not as its aloowing me connection on my laptop plus moble ????
Try pressing Xbox button > Settings > Network Settings > Wired or Wireless > Configure Network > Additional Setting > Restore to Factory Settings then test connection! Your best bet would be use an ethernet cable though less lagging in partys and games!
