Asus RT-N18U problém s odpojením

Zdravím,
poradil by mi někdo s tímto?
Router Asus RT-N18U spojený (mimo jiné) s TV Samsung LE37D550 - kabelem, na které běží pohádky ze Zyxel NSA310 přes DLNA, problém je, že se TV čas od času od NSA odpojí, přijde mi to jako zcela náhodné (někdy OK, teď 2x během hodiny), ale kouknul jsem na log z routeru a jsou tam mraky těchto záznamů (adresa 192.168.1.52 je TV)
Díky
