Hi,
Sinds kort bij T-Mobile glasvezel. Ik heb een synology server. 2 deco systemen achter mijn modem voor de wifi apparaten. Mijn synology doet elk uur een speedtest. Zie foto. Mijn verbinding fluctueert enorm! Heb de logboeken bekeken en zag aantal PING OF DEATH ATTACK. Niet heel boeiend, maar het zijn er wel veel. Kan dit mijn verbinding vertragen?
Ik heb mijn 2 deco systemen al losgekoppeld, om de verbinding te testen met alleen de synology gekoppeld aan het modem. Zelfde resultaten helaas.
192.168.1.221 - dit IP adres is mijn mobiele telefoon
Hier het logboek van modem:

Mooie grafiek omtrent jouw verbinding.
Snelheid is niks mis mee. Mooie UP- en DOWN-load snelheden.
Naar dergelijke grafieken gaan zitten staren helpt je nergens mee. Wel om te zien dat je op 21 augustus tussen ongeveer tussen 12:00 en 19:00 geen speedtest gegevens hebt.
Was op dat moment de speedtest server down of was de kabel van jouw verbinding eruit en misschien was dit ontstaan omdat er iemand in de POP per ongeluk de kabel had lost getrokken.
Vergeet niet dat "Het Internet” een heleboel verbindingen naar een heleboel servers zijn. Als iedereen op hetzelfde moment een connectie naar bijvoorbeeld Google probeert te maken stroopt het data verkeer naar Google een beetje op. Als jij op dat moment een snelheid test opstart beland je in die file van gegevens. Al eens in een file stil gestaan? Dan weet je dat het even tijd kost voordat het opgelost is.
Staat je niet blind op die grafiek maar beoordeel hem op het algemene beeld dat getoond wordt. En daar zien we een up- en download snelheid van tegen de 1000 megabit. Mooi toch.
De onderbrekingen naar “0” heb je misschien zelf al de verklaringen voor.
Met je verbinding is niks mis. Als blijkt dat jouw IP-adres Ping of Death attacks krijgt zal er iemand zitten klooien naar jouw internet verbinding.
(Misschien een “vriendje” die je zit te pesten?)
Dit soort aanvallen zie ik in mijn modem log nagenoeg niet voorbij komen en mijn speedtest grafieken zien er gelijkwaardig uit met die van jou. Ik wat lagere up en down maar dat kan ook ontstaan aan de manier van testen en hoe de grafiek getoond wordt.
