This modem works great but I have one problem. When my son uses the xbox this motorola surfboard modem sb6121 will reboot about once every 20 minutes. The whole house runs fine, the tv wifi, computer wifi, tablet, phones and no problems even if they run all at the same time. But when the xbox gets turned on the modem will reboot every 15 to 20 minutes.
WHY?? help.
