4. Router defective within 8 months

Well, I’ve never heard that before. I’m not an electrician, but I would start by plugging the power supply into a different outlet.

Ev. Use a UPS (line-interactive) for the router?

@Kessirio24

A device can be destroyed if any overvoltage (voltage spikes) reaches the device or high temperatures are present.

Even if there were overvoltage across the network, this could cause a defect.

It would be interesting if Swisscom would look into this problem in more detail and then give an indication of what exactly was defective.

In any case, so many defects in such a short period of time - it’s extraordinary.

N.b. Is it possible that you have previously reported a problem with the Anschluss under a different name with reference to (a PV system)?

@Kessirio24

In principle, there is no known general failure problem with the Internetbox power supplies - as long as they are operated on normal voltage networks 220-240VAC / 50 Hz.

Is this a “normal” PV with 3-phase inverter or a special design? (The “power optimizers” mentioned are on the DC side and certainly have no influence on the AC side of the inverter)

The inverters of the PV system may have a “fire” and bring voltage peaks and/or high-frequency interference/harmonics into the network that the IB power supply does not get…..

The 230V network should be measured with an analyzer to see whether everything is clean.

Inline UPS and/or line filter for the power supply would combat the symptoms but not solve the cause

I can say from my own experiences with PVA 3-phase and LFP batteries with their own 1-phase solution that the devices “mess up” the power grid. What I see about high-frequency ripple on the 230V is brutal. What’s interesting is that switching off the devices hardly makes the interference go away, only physically disconnecting the panels and the BMS in the battery does. Only when everything is really dead will there be peace on the internet. But when everything is active, not even a few Schaffner filters are of any use. They protect against the peaks, but not from the EMI. I find the EMI from the solar panels, which actually only produce DC, exciting. There are significantly fewer disturbances at night.

But these relatively minor disturbances or voltage peaks do not hurt routers or power supplies. These would then have to be more massive peaks that come close to the effects of lightning. In addition, the problems only occur intermittently and then apparently nothing again for weeks.

I’m therefore guessing EMI, which can somehow destroy the router. So not even via the 230V network, but over the air. I once had this problem with a customer whose router kept rebooting when he pursued his amateur radio hobby. Another idea is that due to the disruptions, the firmware upgrades don’t work and so the router is dead afterwards.

A tip from me would be to somehow shield the router from EMI and use a line filter. Sounds stupid, but wrap it in aluminum foil (of course, with WiFi it’s over, it’s best to use a WiFi box) and watch the whole thing. The customer did this at the time and was so helpful. I think today he packed the router in a cookie jar and no more problems.

However, since this is a rather rare case, no one will probably go out on a limb and make great efforts to analyze the problem. We also don’t have the same analysis options for Wingo customers as we do for our own.

Hello @Kessirio24 The only question now is whether the fiber optic module is giving up or the router itself.

If you were still on BX, you could only change the module. Blue plug.

But not when the blue LED lights up!

The “optimizers” could sometimes cause really massive problems ([Bakom link](https://www.bakom.admin.ch/bakom/de/home/das-bakom/medieninformationen/bakom-infomailing/bakom-infomailing-43/ photovoltaic-systems-avoidance-of-possible-disturbances-at-radio-frequencies.html)) and hypothetically also interfere with Ethernet if the Ethernet cable is close to the supply line.

Can you perhaps notice a pattern that the disturbances only occur during the day? Because the optimizers should probably be without power at night.

@Kessirio24
The optimizers continue to work even if the system is disconnected from the network. They get their electricity directly from the solar modules. At least during the day.

The interference would then be capacitively coupled in from the DC line.

But speculating doesn’t help much; you have to measure it. If you live nearby, I could do that (Kt. TI).
Or you can make a non-binding inquiry to OFCOM. Or perhaps at an amateur radio club nearby.

Electricity providers can also measure power quality (interference from the network), but this is sometimes not free.

Hello everyone

I’m at Wingo and have the exact same problem. After replacing the router for the fourth time, I noticed that the router could be reset despite the blue LED: simply switch it off once and then press the reset hole when switching it on. After a few blinks it then starts again (with factory settings of course).

This was also reported to support and they forwarded it for analysis.

Since then (approx. 6 months) I have not received any meaningful feedback other than that the analysis is still in progress. Unfortunately the blue LED comes back every 1-2 weeks…

And to take the wind out of the sails of the photovoltaics/optimizer thesis: I don’t have any of it in my building…

Unfortunately, I’m at my wits’ end and have been thinking about setting up a compatible router from a third-party manufacturer

@Pfaff

Is it possible that there is still D-LAN (Powerline) in the house, but it can only have an influence on a copper line and not fiber optics?

@WalterB

At least in my apartment there is no powerline. (Of course I can’t speak for the other apartments)

But as you already wrote, I would find an influence on fiber optics strange…

What’s also amazing is that at first it worked without any problems for about a year. Now, since the beginning of the year, the blue LED has been appearing regularly. This occurred without any changes to my network and, as far as I could tell, not to the building either.

Due to the multiple changes, I already had the IB3 and the IB4 in operation. Same phenomenon for both…

At the beginning the problem often occurred at some point at night because everything was ok in the evening and then the blue LED in the morning. That’s why I suspected that there was a firmware update that didn’t go through and the IB then malfunctioned. But the Wingo support said that there were no updates at all…

Now the error appears to occur randomly at any time of the day or night.

I was also wondering whether there might be interference signals somehow in the LAN that could “shoot back” to the IB. That’s why I connected all the devices to a Netgear GS105 switch, so that only the fiber optics and the switch are directly attached to the IB. Unfortunately also without success

@Pfaff

If you then switch the Internet box at the back off and on when the “blue” LED appears, does it work normally again or does the “blue” LED come back after 5-6 minutes?
