Sg att vi ska g in p flashback.org, d tar det 2-3 sekunder innan ngonting hnder och sedan gr det jttesnabbt. Det r likadant oavsett vad man gr. Kolla p youtube; tar 2-3 sekunder innan den brjar ladda och sedan gr det jttesnabbt (jag har 100/100, s snabbt ska det g...).
Problemet uppstod efter jag frskt ppna portar. Fljde olika guider p ntet som inte hjlpte ett skit tyvrr. S nu sitter jag hr med fortsatt stngda portar och ett frustrerande internet.
Har fabriksterstllt routern, ingen skillnad.
Ngon som har frslag p vad jag kan ha gjort fr tokigt och hur jag kan lsa det?
Kan du pinga lite olika adresser i kommandotolken och ange din responstid?
Antingen r det att DNS-uppslagen drar ut p tiden och d r det bara att byta DNS-server. Eller s r det din internetleverantr som har problem med prestandan.

Det lter som DNS-anropet tar ngon extra omvg eller ngot.
ppna "Ntverksverktyg" och anvnd verktygen (brja med 'netstat') fr vi se hur det gr.
Jag har inte riktigt pensionrsniv nr det kommer till datorer, men det hr frstod jag mig p. S jag klistrar in allt som verkar intressant s hoppas jag att ngon orkar titta p det. Antar att det gr snabbt om man vet vad man letar efter.
