Sinds de snelheidsaanpassing van afgelopen donderdag 26 maart 2020, heb ik herhaaldelijk en reproduceerbaar Internet verbindingsproblemen.
Een constante ping bevat veelvoudig packetloss. Vooral te veroorzaken als ik een groot bestand wil uploaden maar ook al als ik de Speedtest uitvoer. De download gaat dan prima, ruim 200 Mbps, maar de upload breekt al na 2-3 seconden af, haalt even de 40-50 Mbps maar daarna valt deze volledig weg.
Tegelijkertijd heb ik de ping lopen en die geeft dan direct een time-out.
In het kabelmodem logboek zie ik deze meldingen voorbij komen:
