Hi,
the modem / router I have (Dynalink /Zyxel Prestige 660H-61) generraly works OK but sometimes it shows that it is connected (the DSL/PPP light shows that everything is OK - it is amber colour) but my browser says "page not found" to any page I try. This gets fixed after a few minutes, resetting the router does not always fix it. Can it be a line quality issue?

Here is what the the modem testing function generates, I would appreciate if anyone who understands this can draw a conclusion - is it the line or not? These readings are collected during one of these moments when no page can be found... Thank you.
