What do I need to check/do to get networking back?

I was able to connect to the internet until I installed some ports. Since I used:

# portmaster [FILE]category/port[/FILE] [FILE]category/port[/FILE] [FILE]category/port[/FILE]

I do not know which port caused me to lose my network connection. My system had locked up so I had to reboot and ever since then, I have not had a network connection.

# ifconfig -a

What commands, in which order, do I need to execute to have FreeBSD test for the card, initialize it, then start networking? Also, what files should I check to make sure the settings are what they should be?

Your interface is missing IP address,
Try first
# dhclient dc0
Click to expand...
I ran your command and I got:
Code: 
DHCPDISCOVER on dc0 to 255.255.255.255 port 67 interval 4
DHCPDISCOVER on dc0 to 255.255.255.255 port 67 interval 10
DHCPDISCOVER on dc0 to 255.255.255.255 port 67 interval 11
DHCPDISCOVER on dc0 to 255.255.255.255 port 67 interval 16
DHCPDISCOVER on dc0 to 255.255.255.255 port 67 interval 19
DHCPDISCOVER on dc0 to 255.255.255.255 port 67 interval 1
No DHCPOFFERS received.
No working leases in persistent database - sleeping.
 
How do you usually configure dc0?
$ grep dc0 /etc/rc.conf

Chances are slim that a port was responsible, but can you retrieve from your shells history what ports were upgraded prior to the network failure?
 
Check your /etc/rc.conf file for the ifconfig_dc0 line. If it's set to DHCP, then you need a DHCP server on the network to hand out IPs (and it looks like you don't, since the dhclient command failed). If it's set to a specific IP, then double-check the line to make sure it's valid. Try to set that IP on the command-line.

From the sounds of it, your rc.conf is probably corrupt, so it's not setting the IP.
 
The dhclient command should still work even if /etc/rc.conf is corrupt (assuming the hardware is working correctly), maybe a restart of modem/router is needed?

That last line suggests that it had not been using DHCP, or an old lease would probably have been used. So check /etc/rc.conf. Maybe an enable line for one of the new ports is missing a quote and blocking the static ifconfig line.
