Check your network cable connectors: are they making solid contact? Are the network cables free of pet chewings, cuts, and crimps? Always check the easy stuff first!

Otherwise, it could also be a problem with your Realtek card (they're not great) or something to do with the DSL modem. You can collect some useful information:

Is this a notebook or desktop? What model of DSL modem do you have?

Which version of Realtek card you have: # pciconf -lv | grep -B1 -A2 -i network

How it is set up in /etc/rc.conf:# grep ifconfig /etc/rc.conf

What ifconfig thinks:# ifconfig re0

i think not a problem, because in ubuntu linux fine.

Is this a notebook or desktop?
i use a PC.. dualboot ubuntu-lucid lyn and freebsd-8.0

Code:
rootBSD# pciconf -lv | grep -B1 -A2 -i network
    device     = 'Gigabit Ethernet NIC(NDIS 6.0) (RTL8168/8111)'
    class      = network
    subclass   = ethernet
rootBSD# grep ifconfig /etc/rc.conf
ifconfig_re0="inet 192.168.1.103  netmask 255.255.255.0"
rootBSD# ifconfig re0
re0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500
	options=389b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC>
	ether 00:e0:4d:4f:7c:38
	media: Ethernet autoselect (10baseT/UTP <half-duplex>)

Okay, run # ifconfig eth0 on Ubuntu and compare. Does it also come up as 10baseTX and half-duplex?

Oh, and what version of FreeBSD are you running?

Doh. Apparently you have to use # ethtool eth0on Linux.

The reason I ask is that I'm think an autonegotiation error. But maybe that's not it. I know there have been changes to the re driver since FreeBSD-8.0; you could update to 8-stable.

Under Ubuntu, it goes to 100Mb and full duplex. You can try manually setting that on FreeBSD with # ifconfig re0 media 100baseTX mediaopt full-duplex
