Here are a few analysis points:

• The line length is more than 1250m over long overhead lines
• Still it is a stable signal without any interference
• The line was stabilized, maybe you could still get 5-10mbps out of it
• It’s an SME account, which means I’m not allowed to do any manual optimization (only if the customer gives their OK)
• I can’t find any problems in-house, looks good
• 5G Booster is not available to SME customers (it would only be TCP, not yet UDP). Therefore, the customer must call his customer advisor to find out what options there are for SME customers to increase the speed.

Conclusion:
Yes, the performance of the line far in the country is not better and will only be with mobile support. So I can certainly imagine that he has to download so much for the scenery that he can’t keep up, especially if something else on the internet is pulling data. The diagnostic menu in the router, where you can see the download/upload, can give you an indication of this. The Anschluss is only partially suitable for gaming at very high resolution.

Best regards

@Roger G

What do you mean by in-house, just the line from the UP to the IB?

I assume that you cannot determine remotely whether the LAN is built as split multimedia, for example. This means that the statement that no problems can be identified in-house is likely to be very bold or at least misleading.

• inHouse is always from the UP to the router, including patch panel and sockets, but only DSL signal (or BEP to OTO and router with fiber optic)… so everything in front of the router in the building.
• Everything after the router is the home or company network, i.e. Ethernet, WLAN and the rest of the stuff

@Roger G

In your nomenclature or that of Swisscom it may be understood that way, but from the customer’s perspective it is not so clear. By InHouse, customers understand the house installation and do not differentiate between the UP <> IB part and the LAN.

In my opinion, it would be better and unambiguous if the individual sections in customer communication were named as follows:

- Swisscom cable to the transfer box/connection box

- Cable between transfer point/connection box and Internet box

- Network (LAN) between Internet box and end device (e.g. TV-Box)

The description will be longer than if you only use one word or an abbreviation at a time, but it is certainly easier to understand for the layperson.

@Paubario19

Yes, you could roughly summarize it like that.

Do you need the SME-Anschluss or would a private customer connection be sufficient?

In this case, you could try using the 5G booster (there is a return policy of 10 days) and @Roger G could also try to tune the Anschluss a little more easily (see post #35).

There are routers (unfortunately the IB doesn’t) that can correct your error (ping times increase significantly under load) by slightly throttling the maximum usable bandwidth in favor of a trouble-free connection.

I adjusted my g.fast line a bit; My boys often complained about stalling and lagging in online games until I set the line data from 550/120 in the router to 500/100. I think the result speaks for itself…

@Paubario19

Although you cannot limit the bandwidth of individual devices on the IB, you can prioritize individual devices (e.g. the gaming PC or PS4/5) in the IB (keyword QoS).

However, you cannot use this to blend the TV and the phone, as these have the highest priority.

@kaetho

Have you also tried the IB’s QoS settings?

The Centro Business 2 is not an Internet box and has completely different firmware. This is a router for smaller Geschäftskunden. I have no idea whether it has such functions.

@Paubario19

It is quite possible that this setting only exists on the IB, but not on the CB. Is there a reason you use a CB?
