That link should be the first place you look. The loss is happening after hop 2, so we need to send the engineer to look at the link between the second router and 10.2.0.2 as its probably broken/congested. This response creates an important finding. $ mtr -report 10.2.0.2 HOST: example Loss% Snt Last Avg Best Wrst StDev 1. We are going to go from computer to computer via two routers. Now let’s look at this in a larger network. Best send someone to look at it! Our broken routed network
Looks like we are having a bad time on our network with 20% packet loss spotted.

The tool we are going to use for this is ping, which is on most Windows or Linux computers as a command line tool.įrom 192.168.0.2, we will ping 192.168.0.3 ten times with the following command:
No routers are involved.Īsk an engineer what the first step to solving any problem and the answer you’ll probably hear back is ‘replicate it’ because if you can’t measure it, you can’t identify if you have fixed the issue or not. The two computers are connected through a switch on the same subnet. In the diagram below, I have a small segment of a larger network where we suspect packet loss. Packet loss is something that should be avoided wherever possible and is a symptom of network issues such as lack of capacity or failing devices. Packet loss is a problem that can affect any given network, slowing transfers to a halt and making real time streams such as VoIP or video streams unusable. Packet loss will still have some minor knock on affects since it may increase the CPU load to process the additional network overhead. Sometimes this can result in a loss or reduction in quality to latency sensitive protocols or applications such as streaming video or voice over IP, where there is less of a requirement for accuracy. Packet loss will generally reduce the speed or throughput of a given connection. Other causes tend to include faulty hardware, general radio based issues and in some cases, packets can be dropped intentionally by devices to achieve a purpose such as limiting traffic throughput or for routing purposes. One of the most common causes of packet loss is congestion, the act of having a link close to its maximum throughput that can often cause packets to start getting dropped. For example, you could probably lose 1% of all the packets involved in a SIP VoIP call and have no issues. Noise on the phone line causes problems, but they tend to be random, and not at fixed intervals as you describe.While it sounds like an oxymoron as packet loss should not be acceptable, many application/protocol designers are aware that packet loss happens, and as such, protocols are designed to tolerate it. You will also need to get hold of a cheap wired phone (less than £10), to eliminated any other possible issues with your phone line, which is making things worse. You can turn the power off to the boiler, just to make sure its that which is causing the problem. If you do hear that loud buzzing noise, and it ties up with the problem on the broadband, the only solution is to get the boiler thermostat changed.

If you have access to a portable medium wave radio which you can put near the boiler, you may hear a loud buzzing sound which could last up to 10 seconds, as the boiler thermostat switches the gas supply off. This generated a lot of radio interference which will be picked up by any phone wiring, and either cause a lot of errors on the broadband connection, or even cause a total loss of signal. What happens is that the internal boiler thermostat which switches the gas valve on and off, is arcing instead of switching cleanly off. I suspect that its quite a few years old, and possibly a Thorn or Potterton one, as is a known fault which happens as they get older. There is nothing you can do to the hub or the wiring, the issue is with the boiler itself.
