VDSL modem connection problem

I get disconnected every now and then and I suspect it’s the insufficient firewall configuration fault. I use safe mode.

I log to 192.168.1.1 to set my services settings. I’ve noticed that in my firewall log there are some blocking events related to that IP. There are ICMP requests. So I’ve added a global rule allowing every type of ICMP from that IP. That didn’t help.

With a VDSL modem my money would be on the connection between your modem and the outside world. VDSL is, more so than ADSL (2+), sensitive to line conditions. Did this problem arise when you switched from ADSL to VDSL?

I would suggest to check out the connection stats of your modem and see how many errors are reported and also contact the helpdesk of your ISP.

I just wanted to eliminate firewall from the troubleshooting chain. Thank you.
