I had a similar problem with rl(4), but thought it was due to the
wireless radio (wireless ISP) that was the cause of the problem due to
storms last night.  I did notice, while running tcpdump, that FreeBSD
was trying to obtain the mac address of the wireless radio, but the
radio wasn't responding. I then used 'arp -s <IP of wireless radio>
<MAC for wireless radio>'

This morning it still wasn't working, so I powercycled the radio, and
the ethernet switch.  I then noticed that the radio was now trying to
obtain the mac address of the FreeBSD system, but it wasn't
responding.  Tried ifconfig rl0 down/up of the interface and it still
wasn't sending out arp replies.  Rebooted the system, and now I can
access the internet thru this system.
