Ήρθε λοιπόν το ADSL2+ στην Αμαλιάδα. Όμως πως είναι η ποιότητα των γραμμών; Σε τί ταχύτητες κλειδώνουν τα routers? Καλείται ο Kapsotronix να μας πει την γνώμη του. Εγώ παραθέτω κάποια στοιχεία που μπορεί να βοηθήσουν (από ADSLGR.COM)

ΟΙ ΤΑΧΥΤΗΤΕΣ ΜΕΤΑΔΟΣΗΣ ΔΕΝ ΕΞΑΡΤΩΝΤΑΙ ΑΠΟ ΤΑ ΧΑΡΑΚΤΗΡΙΣΤΙΚΑ ΤΗΣ ΓΡΑΜΜΗΣ!!!!!! [/b] εκτός από εξαιρετικές περιπτώσεις.

Το download δηλαδή μια στο 18mbit και μια στο 20mbits και το upload στο 812 Πάντα. Δικιολογείται για 100 μέτρα αντε 200 από το κέντρο του ΟΤΕ γιατρέ μου; Να τους πάρω να τους τρέξω;

Μια χαρά είσαι Χρήστο. Ναι είσαι δίπλα στο DSLAM αλλά να τελικιάσει χλωμό το κόβω...
Το πολύ να σταθεροποιηθεί στα 20. Για το upload ίσως έχεις δίκιο να γκρινιάζεις... Ψάξτο...

Axrst · 25 Ιανουαρίου 2008

Με λίγο καλύτερο Noise Margin, η ταχύτητα στο download ανεβαίνει μέχρι 21314, αλλά το upload εκεί... στα 820...
