Me also have been having similar problems.

I have a realtek 8139 and a cable modem. I use DHCP to connect to the network 
and my /etc/dhclient.conf has nothing on it.

My problems are:
	The speed of my connections are way slower in FreeBSD than are in windows; 
To the extent of downloading at 2 kps when in windows I would download the 
same file from the same site at 70kps.
	My connection gets 100% packets lost if I put for example cvsup and a 
download from the ports tree working at the same time. (and sometimes even 
with a single download it just hangs...)

I shall now insert a few system info:

I'm running a 4.2 stable box, cvsupdated about 2 weeks ago.
I have IPFilter running.

ipf.rules:
#Block all from all protocols
block in log first on rl0 proto icmp from any to any
block in log first on rl0 proto tcp from any to any
block in log first on rl0 proto udp from any to any

#Block in for X
block in log first on rl0 proto tcp/udp/icmp from any to any port = 6000

#Block in for smtp
block in log first on rl0 proto tcp/udp/icmp from any to any port = smtp

#Anti spoofing rules
block in quick on rl0 from 127.0.0.0/8 to any
block in quick on rl0 from 0.0.0.0/8   to any

#Pass mail
#pass in on rl0 proto tcp from any to any port = smtp

#Pass FTP Connections
pass in on rl0 proto tcp from any to any port = ftp
pass in on rl0 proto tcp from any to any port = ftp-data

#Pass dhis
pass in on rl0 proto udp from any to any port = 58800

#Pass out all
pass out on rl0 proto tcp from any to any keep state keep frags
pass out on rl0 proto udp from any to any keep state keep frags
pass out on rl0 proto icmp from any to any keep state keep frags
