Ich bin Telekomkunde mit MagentaZuhause L VDSL Internet. Ich benutze ein ASUS DSL-AC56U (Modem+Router) mit der neuesten Firmware:

• DSL Driver Version FwVer: 5.6.36.0_A_A60901 HwVer:T14.F7_0.2
• Firmware Version: 1.1.2.3_993-g9de7917

Jeden Tag bricht die DSL-Verbindung mehrmals für einige Minuten ab. Auszug aus dem Logs:

Wie kann ich das lösen? Ist das ein Modem- oder Telekomproblem?
