Downloads en youtube-videos werken niet thuis, wel op kot

[Nicolas Vdp.]

Hallo,

Zoals de titel al zegt heb ik regelmatig problemen met het bekijken van filmpjes op youtube en het downloaden van bestanden van het internet. Downloads gaan meestal een 10-tal seconden goed, maar vervolgens vertraagd de snelheid systematisch en stopt uiteindelijk. Filmpjes bufferen maar tot halverwege en stoppen dan ineens. Om de rest van de video te bekijken moet ik dan een paar keer de pagina verversen of in de "tijdsbalk" klikken.

Dit probleem heb ik enkel als ik op het netwerk bij mijn ouders zit. Gebruik ik dezelfde laptop op kot, dan werkt alles prima.

Ik denk persoonlijk dat het om een probleem met de router gaat, maar weet niet hoe ik dit kan controleren. Voor alle zekerheid heb ik scans gedaan met McAfee Antivirus Plus en Malwarebytes' Anti-Malware, beiden waren negatief. Ook heb ik een HijackThis-log

gemaakt (zie hieronder).

Alle hulp is welkom!

Groeten,

Nicolas
