Wan not getting a New IP when internet drops

[musicwizard]

Im not getting a wan IP when my internet drops.

I got a experiabox V9 (KPN)  when that connections fails and it says like that and it gets back up for like 20-30 min, my pfsense box isnt getting a new Wan ip will i restart the php-fpm Because unbound and other services will have a high load and wont come back up so my internet comes up and goes back down again.

Like today i wasnt at home and it connection was keeping back up and down a lot of time in a 2-3 hours time span. While internet it self was already up for a long time again.
so had to restart the router to get it working correctly again.

This happend now 3 times in a short time.  Cant really find a solution to it but its getting very irritating.

i dont have many services runnig
APC        UPS Daemon

apinger    Gateway Monitoring Daemon

dhcpd DHCP Service

dnsbl pfBlockerNG DNSBL

ntpd NTP clock sync

openvpn OpenVPN server

snort Snort IDS/IPS Daemon

sshd Secure Shell Daemon

unbound DNS Resolver

Dont have many packages running either.

What type of WAN? DHCP, PPPoE, …? What logs are you getting at the time?
