      I've been having this problem since January.  I found that if I pull out the ethernet cable and replug it back in, it'll start working again for a while.

      It's been getting worse recently.  Thought it was my DSL or Clearwire, but bypassing the FW proved they were fine.

      I thought it might be my USB ethernet adapters.  (Since my box only has one ethernet port, I have to use USB for WAN and OPT1.)  But other brands of USB ethernet also failed.

      After reading this thread, I went back to 2.0.2, but forgot that my ethernet card isn't supported in FreeBSD 8.1, so I tried the 2.1 beta disc I made back on Nov 29th, and things seem very stable at the moment.  – I started fresh with minimal configuration/tweaking and have not upgraded.

      I did have an AMD proc and powernow settings enabled.  In retrospect, I should've tested that, or some of the other advanced ethernet settings...

        Update: Stable overnite running on 2.0.1. Will continue to monitor.

          I have the same problem my work around is creating a script which pings google and if packet lost my network card restarts

          copy and save this file in the root home directory called wan_check.sh

          #!/usr/bin/env bash
          #/usr/local/bin/network_check
          
          # Script to monitor and restart network card
          
          maxPloss=10 #Maximum percent packet loss before a restart
          
          restart_networking() {
                  # Add any commands need to get network back up and running
                  sh /root/wan.sh
          
          }
          
          # First make sure we can resolve google, otherwise 'ping -w' would hang
          if ! $(host -W5 www.google.com > /dev/null 2>&1); then
                  #Make a note in syslog
                  logger "network_check: Network connection is down, restarting network ..."
                  restart_networking
                  exit
          fi
          
          # Initialize to a value that would force a restart
          # (just in case ping gives an error and ploss doesn't get set)
          ploss=101
          # now ping google for 10 seconds and count packet loss
          ploss=$(ping -q -w10 www.google.com | grep -o "[0-9]*%" | tr -d %) > /dev/null 2>&1
          
          if [ "$ploss" -gt "$maxPloss" ]; then
                  logger "Packet loss ($ploss%) exceeded $maxPloss, restarting network ..."
                  restart_networking
          fi
          
          

          This code will restart Wan if ping loses packets.  change de1 to your wan interface
          name this file wan.sh

          ifconfig de1 down
          sleep 5
          ifconfig de1 up
          dhclient de1
          
          

          change the attriputes (Chmod) to 777 on both files
          and setup cron job to check the wan interface every 30 min
          30  0  *  *  *  root  /root/wan_check.sh

          Note I had to make the folowing change because running under Hyper-v.  Change Speed and duplex to "100 base tx full duplex" this located under interface–> WAN

            What do you all have powerd set to?

            Mine seems to fail when powerd is checked.  But that could be just coincidence…  (Looking for patterns.)

                So, I updated from 2012-11-29 to today and the problem returned.

                However, reconfiguring from scratch, I made the WAN & OPT IP's static, and it seems stable.  (Though static means I have to NAT again through the modems.)

                  Do you guys have OpenVPN configured (but perhaps not used) by any chance? I'm starting to think that this may have started for me about the time I started messing with OpenVPN (I got interested when the IOS OpenVPN App came out). I came across a post here somewhere that seemed to correlate one of the various error messages with OpenVPN.

                  I just whacked the OpenVPN config on my system to see if it stabilizes at all. We'll see what happens.

                    I do have openvpn configured.  I use it for my tablet when I'm away from home.

                      I just did a 100% clean install of 2.1.  Didn't bring in any old config, just configured a handfull of NATs that I need. No VPN, etc. We'll see how this one goes…

                        At least I seem to be moving the ball around…  (Oh, my apologies for spreading this around to multiple areas of the support forum. Since I'm now on 2.1, I'll try and put things here and redirect the others to here. Bad forum behavior, I know - sorry!)

                        Fresh, clean, no-legacy install of 2.1 -- still fails, but failed differently this time.

                        Files as they looked before release/renew:

                        exiting.
                        
                        [2.1-BETA1][root@gw.tubas.net]/var/etc(13): cat dhclient_wan.conf 
                        interface "ue0" {
                        timeout 60;
                        retry 15;
                        select-timeout 0;
                        initial-interval 1;
                        
                         script "/sbin/dhclient-script";
                        }
                        
                        

                        No significant DHCP traffic on tcpdump at this time on the WAN interface (filtering on port 67). Removing the filter, I saw normal looking arp traffic.

                        tcpdump while doing release/renew (at least that works again to restore service!) produced minimal output, but it looks reasonable to me:

                        So, something changed by doing a fresh install of the 2.1 snapshot, but things still seme broken.

                          Even with static IPs on WAN and OPT1, I still get lots of these in my dmesg logs:

                          ue1: link state changed to DOWN
                          ue1: link state changed to UP
                          ue0: link state changed to DOWN
                          ue0: link state changed to UP
                          pfsync0: promiscuous mode disabled
                          ue0: link state changed to DOWN
                          ue0: link state changed to UP
                          ue0: link state changed to DOWN
                          ue0: link state changed to UP
                          pfsync0: promiscuous mode enabled

                          I'm getting small % packet loss, which seems to correlate to the link states.  But there's no interruption in web surfing.

                          I don't have OpenVPN enabled/configured.  I do have the export keys module installed, but haven't done anything with that yet.

                            So I had configured a couple of dynamic DNS updaters, but decided to pull them out for one reason or another.

                            Upon deleting them, this appears in the system.log:

                            
                            Mar  1 01:05:29 gw php: /services_dyndns.php: The command '/bin/rm /conf/dyndns_*.cache' returned exit code '1', the output was 'rm: /conf/dyndns_wandyndns'travisd.dyndns.org'0.cache: Read-only file system rm: /conf/dyndns_wanopendns'travisd.dyndns.org'1.cache: Read-only file system' 
                            
                            

                            …and the WAN link dies again (loses it's IP address)

                            Manually trying to remove these replicates the issue:

                            
                            [2.1-BETA1][root@gw.tubas.net]/conf(12): rm -f dyndns_*
                            rm: dyndns_wandyndns'travisd.dyndns.org'0.cache: Read-only file system
                            rm: dyndns_wanopendns'travisd.dyndns.org'1.cache: Read-only file system
                            
                            

                            Edit: More logs, this is what spits out now when it dies (and before manual recovery via release/renew)

                              But what particular build of 2.1?

                              The log extract you posted shows multiple dhclient copies running. This seems like a bad idea - they could easily interfere with each other in unpredictable ways. I think I have seen recent posts addressing this issue. The multiple reports: Feb 28 23:26:06 gw php: : rc.newwanip: Informational is starting ue0. in the original log you posted seem strange in that ue0 shouldn't need to be started (not sure exactly what that started means) immediately after the interface IP address has been set and routes added etc. PERHAPS there is a synchronisation issue between multiple processes and it generally works OK in some systems (slower systems like mine) but doesn't generally work OK on faster systems.

                              @abeowitz:

                              Even with static IPs on WAN and OPT1, I still get lots of these in my dmesg logs:

                              Its likely that for a time the NICs didn't detect carrier from the devices they are connected to.

                                Yes, I'm running a nanoBSD variant. Currently:

                                2.1-BETA1 (i386)
                                built on Thu Feb 28 04:26:51 EST 2013

                                (but over the last several days I've been trying 2.0.1, 2.0.2, 2.0.3-SNAPSHOT, and a few 2.1 snapshots.

                                This is running on:  Intel(R) Atom(TM) CPU 330 @ 1.60GHz

                                It definitely appears to be a dhclient thing at this point. If I manually kill the running dhclient process and re-start it, things come right back up.

                                  Beginning to believe I have two problems at play.  :-\

                                  #1 is that the USB Ethernet adaptor doesn't seem to be very stable. This is the 2nd adaptor I've tried but same make/model as the first. I swapped the former outside (ue0) and inside (re0) interfaces around so now ue0 is the LAN.  After a little while, I saw it hiccup again, but since it's static it survived:

                                  The second problem seems to be that the quick down/up apparently plays havoc with the dhclient (what we're seeing in the earlier posts).  Related, but different issues from what I see.

                                  I don't consider this fixed - it's just a bandaid solution. What other info can I provide to help here?

                                      Yeah, I left it out of my clean re-install and no change.

                                      Since I moved the USB interface to a static addressed interface, I'm still seeing it flap occasionally, but it doesn't get hung up with dhcp like it did on the WAN side. I think that eliminates my cablemodem from the cause of the flapping problem (it was connected directly to the cablemodem; now ue0 connects to a cisco switch).

                                      ue(4) driver problem? usb issue?

                                      When it flaps, it happens quickly enough where I don't even lose any pings when running a continuous test from another host.

                                        Sure looks like this would be the bug in question, but seems like the fix may not be working.
