Quote:Pollensa1946: There have been various s/w changes to the Humax, including one in late Dec 2015 that caused problems with various TVs. You are not going to find out if CEC is an influencing factor unless you switch it off.
I have gone into Panasonic TV setup and disabled Viera Link and then powered the TV off/on.
Quote:Faust: …when you get your Homeplugs use those then report back.Got the Homeplugs today and I have now connected the Humax box directly to a port on the HH5.
Installed Wireshark on my laptop and have the laptop connected to a port on the HH5 with a display filter of 192.168.0.250 (the IP address of the Humax box).
I will leave Wireshark capturing data for some time and see what turns up.

I’ve got everything crossed for you now. Given what you have done it should be OK as I can’t see how the Humax can interfere with your network now.

… Given what you have done it should be OK as I can’t see how the Humax can interfere with your network now.
The Wireshark program died during the night probably because it ran out of laptop memory. I started the program again but this time I used a capture filter “host 192.168.0.250” instead of a display filter which should greatly reduce the data captured.
When the two PCs were switched on this morning they were able to access the Internet.
This afternoon I woke up the Humax box and it worked fine with Wireshark recording several ARP protocol ‘Who has’ broadcasts and some SSDP protocol to 239.255.255.255 with ‘NOTIFY*/1.1’. I then powered off the Humax using the power button on its remote.
As everything seemed to be working, I decided to bring the Netgear 8-port switch [position 1)] into the equation so I removed the Homeplug’s cable from the HH5 port and connected it to a port in the switch.
I will leave Wireshark monitoring this new setup.
Paul
You would have been well advised to see how you got on with the Homeplugs for a few days first before going anywhere near the network switch. If it was my setup now you have the homeplugs I would use those anyway as they are very reliable and tend to be trouble free.

As a former IT person (31+ years) who looked after the network infrastructure, phones, PCs/laptops, servers etc for 300+ software engineers for 10 years before retiring, I would like to find the cause of my home network lockup problem.
This is why I am adding back one switch at a time with my laptop connected directly to a HH5 port running Wireshark software that is monitoring the network for messages from/to the Humax box.

I have every room in my house wired for ethernet and, as mentioned in an earlier post, some of my Humax boxes are wired thru two or three switches before the router, all without problems. So the use of switches cannot in itself be the cause of your problems. Faust continually extols the virtues of using powerline, and no harm to them in the right situation, but nothing can beat hardwired.

I too have all rooms with PCs/TVs wired for ethernet.
Only used the powerlines to connect the Humax directly to the HH5 so that I could bypass the Netgear switches. Left this running for around 24 hours and there were no problems.
Yesterday afternoon I added in the upstairs switch. To date everything is running fine with both upstairs and downstairs PCs able to access the Internet.
Next, I will add in the downstairs Netgear switch at position 3) and see how that works. This will be back to the orginal configuration that was causing the lockups except that the Panasonic TV’s CEC (Viera Link) has now been switched off!
Note: during all of this Wireshark will be monitoring the network traffic from/to the Humax box.
Could the Panasonic TV’s CEC being enabled cause the lockups?
Paul
You would not think so but if the problem does not reoccur then turning it on again should give a clue with Wireshark monitoring.
Also in IT for 25 years, not in networks but did do a MCSE as an add-on interest.

My own experience is that the Humax implementation is so variable with regard to which make of TV it is plugged into that I no longer use it at all. So the only way is to do as Repassac advises.

I was working as a Civil Engineer for 8 years until a certain Mrs Thatcher came to power (you are probably too young to remember her!) and made huge cuts in public spending which caused me to be made redundant. Luckily I was able to immediately enrol in a one year University MSc course in Computer Science & Applications and the following September get a job in IT with the UK’s largest telecom firm.

The behaviour of the BT YouView (Humax) box’s CEC has also changed recently.
My YouView box is connected to a Samsung TV in our front room and my wife found it very easy to use as all she had to do was press the power button on the YouView remote and the TV powered up showing the YouView screen.
Pressing the power button on the YouView remote now wakes the TV but doesn’t display the YouView screen! This really confuses/annoys my wife and I am called to sort it out each time!!
In this case CEC was very useful.

So how do you view it now, as a negative or positive outcome, really interested.

Technically your devices are hard wired with homeplugs. I actually use a combination of network switches and homeplugs for a faultless network experience.

Very positive!
I was interested in ways of reducing the tedium in the Civil Engineering Consultancy firm and had managed to programme the parabolic design of vertical road curves into a Compucorp programmable calculator with storage of only 416 commands. This reduced the design on the calulators we had back then (only had add, subtract, multiply and divide with ability to store one number) from over an hour to under 5 minutes with the results printed out on 2″ wide paper tape which could be attached to the design.
So on the day I got my notice, and being very interested in computers/programming, I went to the University next door which just happened to have an open day in the Computer Science department. I explained my situation to the man in charge of the Computer Science & Applications MSc course and got on the course starting at the beginning of October.
I had to pay the course fees because I couldn’t get a grant at such short notice so I used my redundancy money and got my tax back for the year and this paid for the University course.
But this worked out great for me as my starting salary in IT was £3,300 more than my old job (Civil Engineering did not pay very well back then and probably still doesn’t)!
Another advantage of moving into IT was that I didn’t have to work outside in the rain and wind any more!!

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.
