Sm se odloču novo temo nardit če ima/je imel še kdo take težave da skupaj probamo rešit kje in zakaj ta problem nastane.

Start/Run/cmd -> ping -n 30 najdi.si ali google.com
Pa povejte če se pojav kak Request timed out in kolikokrat. Pri meni se skoraj vedno pojavi vsaj 2krat (6% packetloss).

Nimda nisem takoj obtožil T-2 samo prašal sem na kateri strani je napaka. Packet loss ni tako nedolžna napaka tako da bi jo bilo dobro odpraviti.

Na google.com je pa situacija še hujša:

Ja 100% pingov spravit čez (obremenjeno) mrežo ni tko simpl zadeva... To je ICMP, če se zgubi ne pride do časa nazaj je loss, kar je tudi point tega. TCP bo paketke po potrebi med routerji ponavljal.
