Disconnections with IB3

Hello everyone

Unfortunately, we have been having massive problems with the IB3 at home for a good two weeks.

Briefly about the “path of suffering”

- About 2 years ago we still had 32 Mbit at home. The performance became significantly better with an Internet Booster and IB2. Then came the step to around 140 Mbit with the IB2. This has actually worked quite well so far.

- About half a year ago we received an IB3 without being asked because the IB2 apparently restarted several times and a problem was found.

- We have had the following problem for about 2 weeks:

The IB3 loses its connection to the Internet several times a day and lights up red permanently. Waiting doesn’t help. But as soon as I restart the box the connection works again. I then contacted support and the problem was passed on to an expert. A week ago the appointment was made for today, December 14th, 2020. Funnily enough, from the time I made the appointment over the phone, I no longer had a problem.

Today a very friendly technician came by. I’m by no means an IT specialist but I think he did the following:

First a measurement directly on the router. He noticed a lot of packet loss. The line from the house connection to the router was rebuilt about 2 years ago when we received a Internet-Booster due to problems.

He then took a measurement on the house connection and was able to determine that there was a lot of packet loss there too.

The technician then went to the distribution box 2 houses away and analyzed it there. It appears that a cable was already oxidized black but was too short to rewire. Connections were also not free, etc. He therefore removed the oxidation as best as possible and achieved a slight improvement on the house connection. He said he would definitely report this distribution box for detailed analysis. And then the network builder might have to make a repair/improvement. So far so good.

Unfortunately, after the technician left, I had three interruptions again today, which can only be solved by restarting the IB3. Why did I have to rest for almost a week before? I did some reading and read about self-stabilization. Could it be that my internet had stabilized itself in the meantime and that I no longer had any problems and the technician somehow reset it?

I also have a powerline in the house because I just can’t get everywhere I need to go with the internet. But I only read after the technician’s visit that this could possibly lead to problems.

Here are the measurements since the last restart about 1 hour ago

So in the iB3 site I see that it runs on g.fast.

As already mentioned, a technician was already there today and said he would arrange for this area (I assume distributor) to be looked at more closely and possibly repaired.

I actually don’t want to stir up confusion here when technicians are already taking care of it. I just wanted to ask if you knew of a possible solution to what else could be done in the house.

If it helps, my reference for the error would be 000006355077

Is it possible that this is causing problems for Devolo Dlan? I mean, I wired everything as intended, not in power strips, etc.) I’ve been using the Devolo for about 5 years and have never had any problems of this kind. Unfortunately, I don’t know how long G.fast has been running. I mean, at home I’ve had the current speed of around 140 Mbit for around 1.5 years

Hello Roger, thank you also for your input.

As a test, I will plug the IB3 into another room using an extension cable and observe in the first step.

In the 2nd I’ll try it without the powerline.

Are there any indications that I can monitor to see if it is better? For example at the FEC or crc?

Greetings Philip

Now I had another error.

I immediately plugged the router into a different socket.

After 7 minutes of YouTube about 950,000 FEC down and red light on the router again.

I’ll keep you updated. I’m trying to present the whole thing in Excel in a somewhat clear manner. After the technician’s visit today, I had 5 red LEDs permanently lit.

Edit:
Above all, I’m wondering why this is suddenly happening. Can you see when g.fast was changed over? Can it be related to the latest firmware update of the IB3?

I don’t think it makes sense that after 3 minutes I’m down to 700,000 FEC again.

The best thing: I have a satellite TV that now also works when there is no internet… even though it doesn’t even need it to receive the television signal… I’m really starting to doubt everything.

Thanks and greetings

I am also aware that Gigabit Ethernet is the better choice. But I’m simply not prepared to spend the money on this scale. The house is just too old and there are no clever ways to do this.

It worked more or less well before

Greetings Philip

No, no, I think we’re talking past each other.

It’s clear to me that this is basically possible.

I would just like to know why I’ve only been having problems with this in the last 2 weeks. If at this point they switched to G.fast or loaded new firmware or reset some kind of stabilization, I would understand. But it has to come from somewhere that it no longer works.

By the way, I reconnected the router to its original socket. With the router plugged into a socket in another room, after 10 minutes at the latest I had another interruption with around 2 million Fec down.

Thanks and greetings

Philip
