Chromecast on time warner cable

[sutton241]

My chromecast works great except when I try to connect it to a arris router. The internet service is roadrunner on time warner cable.it just won't communicate with this arris wireless router. Any other router no problem ,I tied connecting to this arris router at several different peoples houses and same thing. Chromecast will not connect to router. Anybody having this problem and how did you fix it ,(if you did.)
