Net se mi ne vzpostavi nazaj samodejno

Em tkole mam kableski internet preko UPC Telemach, imam modem TCM420, iz modema imam speljan utp kabel v strežnik na katerem poganjam freebsd 6.1. V samem stržniku imam 3 mrežne 2 za vsak računalnik posebej in 1 za modem. nastavitve za net v rc.conf imam naslednje:

ifconfig_rl0="DHCP"
natd_enable="YES"
ifconfig_rl1="inet 192.168.0.1 netmask 255.255.255.0"
natd_interface="rl0"
router_flags="-q"
router="/sbin/routed"
router_enable="YES"
defaultrouter="82.192.58.1"
gateway_enable="YES"

Problem pa je naslednji:
- na vsake 1 ali do 3 dni mi pade net dol in se mi ne vzpostavi samodejno nazaj dokler ne sklopim modema iz vtičnice in ga priklopim nazaj, zakaj se mi samodejno ne vzpostav anzaj je problem pri meni ali pri ISP ?

Priložene slike iz modema(log/statistika)
