  1. Truly a high quality post with irrefutable proof and all the information anybody would need to investigate or help.

  2. If I’m reading this correctly you can’t access your home router. That wouldn’t be a problem with the internet connecrion per se, but with your Wi-Fi or cabling in your apartment.

  3. We had an Internet connection that caused intermittent problems for years. Some inspired technician had the inspiration that there was a broken wire inside the connector from the ISP. Sometimes we had a solid connection, sometimes not.

    Check your cables and connectors.

  4. From the picture looks like packet loss it’s all inside local network or last mile, maybe due to your location. I have 10g fiber from Swisscom and don’t have any issue with network.

  5. This is not packet loss as any telco would measure it. A traceroute like the one shown is pinging the routing plane of the devices it goes through which is not the same as the congestion they measure in the forwarding plane and which you as a customer can _only_ suspect or see when observing longer running net flows.

    This is not to say that you _may_ not be using the best performance to a network, nor that _some_ swiss ISP may not have good peering towards some destinations. If you want to influence your purchasing decision with data, look at things like peeringdb.com, RIPE atlas/ris to see how a network behaves on the Internet.

  6. The only real packet loss I can see is on the way to “internetbox.home”, which I assume is your equipment. Either that box or the cabling to it has an issue.

  7. Swiss internet is in fact one of the best in the world. This is a fact based on stats one can find. Local issues, are just that…local issues

  8. I had a similar problem for a year last year. A swisscom person came by. He checked everything, all boxes in my apartment, distribution box of building (he even renewed the connections to the apartment etc). Couldnt find anything. Luckily he didnt charge me any money for it because it took like 3 hours. His conclusion was: the only option left is that there is a connection box somewhere in the apartment/building I cant find that has a bad connection.

    After he left I searched the apartment carefully. Below the electricity distribution box in the apartment, i found a box filled with telecom cables hidden behind the builtin closet.

    I sorted all the cables, cleaned all of the ends nicely. Reconnected everything with new connectors. Surprise surprise problem gone, connection became extremely stable afterwards, and speed doubled.

  9. Sounds like an issue with your Telephone Installation. Is it BBR (probably the case if it’s newer than 10 years). You absolutely need to make sure you have no bridge Taps in your install, best is a direct U72 Cable from your UP to your Phone Socket.

    Source: I do such installs multiple times a week, often electrician mess it up or it’s just an old install, back in the analog telephony days it was done completely different

  10. Packetloss on the first hop is a local network issue, 97% is.. wow.

    On third hop: 100% means no packets returned, which also could mean that this hop just does not respond to trace route/ ICMP packets (third hop is odd, you usually see that further down “the road” which B2B providers that just interconnect ISPs.

    That said, Internet speeds are great in Switzerland, the quality really sucks tho. You can chose between Swisscom that has very reliable and huge outages, or UPC that randomly drops the bandwidth to a 10th of what you pay for.

    Sunrise, I’m not gonna say anything (before and after the upc merger), I’m just tired, especially on 4/5g.

    Currently i write this connected to an I way connection, and while they are great at support, they are not really that cool either. Promised us an upgrade from 20mbit/s to 50 sync because a lot of new buildings were built around us, and they are going to bring fiber here (either them themselves or leased lines), but now they don’t know about that anymore. Bandwidth is rarely above 10mbit/s, working from home in my field is only possible when I can exclude some tasks and be sure at that..

    Only one i can honestly vouch for is init7, but i have no access to them where I live.

    Edit: i just saw that the huge red bar(s) show PL as well. This is definitely a first hop problem, and likely a router issue, especially if you have the same problem on mobile and PC. Check the same when your connecting your PC by cable, then check the firmware of the router (many ISPs don’t Auto-Update) and in the worst case, make 3 tests at various times of the day for a week and attach them to a support ticket where you ask for a new router, this is either the firmware, or the router itself (definitely not router->wan, it’s pc<->router related).

    Keep us updated, curious to see how this is going to be resolved.

    Edit2: another test is to instead of running ping plotter with google.com as a destination, use internetbox.home (or whatever your first hop says as hostname, if the packetloss is still high, this is a confirmation that your lan (wifi, cable, router, PC, or whatever is between your device and the router) is at fault.
