Στο help desk δεν εχουν ιδεα tbh.
Αυτο που κανουν ειναι το λεγομενο Interleaved αλλα σε καμια περιπτωση δε θα εβλεπες αυξηση 30+ ms.

Τραβα Εναρξη (Start) -> Εκτελεση (Run) -> γραψε "cmd" (προφανως χωρις "") -> στο μαυρο παραθυρο που ανοιγει γραφεις "tracert www.otenet.gr". Θα σου βγαλει εν τελει κατι σαν και αυτο :

Code: [Select]

 10    14 ms    12 ms    13 ms  www.otenet.gr [62.103.128.215]
Το καμεις copy/paste εδω. (Για να κανεις copy στο συγκεκριμενο window πρεπει να κανει δεξι κλικ, να επιλεξεις Σημαδι (Mark), να επιλεξεις το κειμενο και να πατησεις enter.

Ξανατραβας Εναρξη (Start) -> Εκτελεση (Run) -> "cmd" -> αλλα γραφεις "tracert www.i3d.net"
Τα ξανακαμεις c/p.

BTW δεν ειχες φοιτητικο?

Πολυ περιεργο λουνα γιατι δεν φαινεται να υπαρχει καποιο τρομερο προβλημα με ping.

Κανε παλι tracert στην ip του 222 και σε καποιο γερμανικο που εχεις 120 ping να δουμε τι παιζει.

Το φοιτητικο εχει διαφορετικη δρομολογηση απο το απλο connex με αποτελεσμα να εχει και διαφορετικα pings.
