    PaulMcI - sometimes, like yours. these outcomes, and other events inspires us to expand ourselves.
    Well done and good luck with the tracking down of your problem.

    Faust - 1 hour ago  » ...Technically your devices are hard wired with homeplugs. I actually use a combination of network switches and homeplugs for a faultless network experience

    If you knew anything about ethernet protocols I think you would agree that powerlines are a compromise solution. Otherwise, why don't major mission critical installations use powerlines, which of course they never will.

    You are trying to move the goal posts. What I said is technically correct, now you are trying to say they are a compromise solution and then move the argument again to mission critical installations. This is a home network not NASA. Besides compromise solutions can and do work quite well in all sorts of situations in all walks of life.

    I'm well aware of the limitations of homeplug adapters in conjunction with a house ring main but that doesn't mean they aren't a good product.

    I think if you examine all of my posts on these forums nowhere will you find me stating they are not a good product. Also I did not try to say they were a compromise solution, I am happy to state definitively that they certainly are, but again I said "no harm to them in the right situation". It's you moving the goalposts in your usual inimitable fashion.

    And you don't think the above statement is trying to move the goal posts? We've gone from a home network to mission critical installations - phew!

    You're clearly having difficulty following this thread, so let me help. I said that powerlines were a compromise solution, otherwise if they were not, and therefor equal to a true ethernet connection, then they would be used by mission critical installations. They are not so ergo they are a compromise solution. OK now?

    Progress!!

    I disconnected the Humax from the powerline adapter and reconnected it to the switch at position 3). Within a few minutes of waking up the Humax box, my downstairs PC at position 3) lost connection to the Internet (Wireshark was capturing all of this - see attached file). I had to pull the power cord out of the back of the Humax box again because it had locked up.

    Removed the Netgear GS605v2 switch at position 3) and replaced it with a TP-Link 5-port gigabit switch (model TL-SG1005D) and powered up the Humax box. Everything worked fine and I left this setup running for some time just to be sure.

    Next, I replaced the TP-Link switch with the now unused Netgear GS105v4 switch from behind the Humax box, position 4). This switch worked fine as well.

    To check if all Netgear GS605v2 switches display the same problem as the previous two used at position 3), I moved the Netgear GS605v2 at position 1) in the study and installed it at position 3). This switch worked fine!

    This morning I received a Netgear GS605v4 switch that I bought on eBay a few days ago (I like the Netgear GS60x switches because the port light glows green for gigabit connections and yellow for lesser speeds). I installed this switch at position 3) and the Humax box is working fine so far and the PC at this position still has access to the Internet as I am writing this post.

    The strange thing is that my two Netgear GS605v2 switches with which the Humax HDR-1000S box has problems don't cause any problems for all my other networked devices!

    If you look at the attached text file captured by Wireshark, Humax_39:8c:2f does several ARP broadcasts and then the following broadcast:

    'Who has 192.168.0.254? Tell 192.168.0.250'

    But 192.168.0.254 is the DNS server!

    After this the HH5 (BTW, Model B) starts ARP broadcasting repeatedly from Arcadyan_7e:b8:fe (do Arcadyan manufacture the HH5 Model B?):

    'Who has 192.168.0.250? Tell 192.168.0.254'

    From my calls to the Humax help who are based in Belfast I know that they read the myhumax.org forum posts!

    So Humax, what is going on and why is the Humax HDR-1000S behaviour different to everything else that I have attached to my home network?

    BTW, when I raised my network lockup with the Humax help back on 11th March of this year the support person suggested that as the Humax HDR-1000S is a Linux box maybe the HH5's Smart Setup switch was set 'On'. After the call, I realised this couldn't be the cause as I have QNAP Linux NAS server which is connected directly to the master switch at position 0) and has been working perfectly since 2008. Anyway, I checked the HH5 setup and the Smart Setup switch was 'Off'.

    If you Google... GS605v2 ...you'll find lots of issues with that switch.

    TP-Link 5-port gigabit switch (model TL-SG1005D)

    I have two of these and have been really pleased with their operation. I'm not a fan of the Netgear as I too have read complaints about them, the lights won't be turning green for streaming video in any event.

    Apols for off topic (but may be interesting to some).

    Powerline signalling is used for many mission critical installations (you need to expand your horizons ). Remote control of switchgear and other kit for instance.

    Simplified example :

    Let's consider the rather large topic of fault detection and clearance on EHV electrical power circuits (Power System Protection). By far the fastest and most reliable method of detecting a fault on say a 200 mile 400kV overhead line (lets say one of National Grid North - South interconnectors), is to compare what's going in at one end with what's coming out at the other. This requires a high speed, 100% reliable two way data interchange between the circuit ends. In the above example, 200 mls apart. Cheapest most reliable way is to impose the data on the power conductors themselves.
