Solved: Internet connection dropping very often

Started a couple weeks ago, with 2 pcs. Last week I got a new laptop, and the same thing happens even if its the only one connected.

One of the first things I did.

Upgraded firmware of routers- didn't help

Ended up doing just this, but they said they can't see any problems on the modem or the line. They forwarded me to a technician, and he said the same thing, but he said he would do a modem upgrade (firmware i guess) but i guess he hasn't gotten around to it yet. I'll be calling again tomorow anyway.

I'm guessing they check the modem event log to see any issues, right?
I can see the next lines under PACKETCABLE(MTA) Events in the modem log. They get written every time my connection drops. Could this be a problem?
AALN/1:/0.0.0.0
AALN/2:/0.0.0.0

AALN/2:opt82.sip.voice.telemach.net/10.143.xx.xxx

Edit for update: doesn't matter anymore. Getting a new modem from ISP
