I had the exact symptom occur. In trying to find out what was happening while logged in to my home system from work (home is where the BSD is) I started pinging and found a 30% packet loss on my home firewall's outside interface. When I got home I found that the jumper cable from the firewall to the cable modem had bee tugged real hard (probably my cats horsing around). I removed and reinserted the cable securely and the problem went away. Hope yours is as simple.
