How many times can an internet connection interruption occur and still be considered acceptable?

[Jonathan Ben Avraham]

Bingo.

This happened to us in Talpiot. Bezeq upgraded the lines without telling 
us that the old D-Link wouldn't work so well. I replaced it with an Edimax 
DSL/Wifi router and that solved the problem instantly.

Of course, everyone denied the story, the ISP (BBL) and Bezeq.
