I will troubleshoot by rebooting your modem. If it is still not working, I will send a technician.

I sincerely apologize for the inconvenience. I will do my best to resolve the issue.

it is not problem on my or your end

Please provide me with the best phone number to reach you.

Is that for mobile hotspot Wi-Fi and hard cable internet?

This looks like a chronic congestion/degradation issue on the Lumen (AS3356) transit segment in Amsterdam that Comcast routes through for this destination range.

Ok

Please provide me with the best phone number to reach you.

There was no connection all day yesterday, and today until 1 p.m., every day before that, there was no connection for at least an hour a day.

Ok

Since I see that you have an intermittent connection—sometimes up, sometimes down—I will do my best to fix it.

Loss begins precisely at the Comcast-to-Lumen handoff (hop 7, ae13.bar4.phi1.sp.lumen.tech) and worsens dramatically at UCOM-LLC.edge7.Amsterdam1.Level3.net (hop 9, 83% loss), then persists at 80-93% through every subsequent hop all the way to the destination. This is not ICMP deprioritization on an intermediate router — the loss is carried through to the final destination and confirmed with real TCP traffic below.

I am going to forward your case to one of the technical teams to investigate the exact issue. A standard service fee may apply if the issue is not related to Comcast equipment or wiring. It seems you might have a wiring issue affecting your signal that needs to be fixed. Please check the PM for a response.

replacement

it is not wiring issue are you read my previous messages?

Ok

Confirmed with a real TCP connection attempt, not just ICMP: curl -v --max-time 15 https://smartex.kg * Trying 91.207.28.50:443... * Connection timed out after 15000 milliseconds curl: (28) Connection timed out after 15000 milliseconds

15 seconds and no tls handshake

As I am showing the first available technician visit on Tuesday, I am trying to get you an exception for the nearest appointment as soon as possible. Don't worry.

Could someone take a look and/or escalate to Lumen?

Also, you can check your services online at business.comcast.com, then Business Internet.

Sure.

I got you an exception for today's appointment. A technician will be there from 8 am to 10 am. Don't worry!

i need tier 2 specialist

Sure.

You just contacted us about an internet issue with packet loss. I did troubleshoot, but you still have an interrupted connection. I got you an exception for Monday morning.

But I am talking about your intermittent connection and packet loss.

connect me with human

This is Mike.

Would you like to cancel your tech?

technician

looks like ai

No, it is not.

Can I keep your appointment?

How will a technician resolve the problem at the backbone provider in Amsterdam?

It is confirmed on Monday.

Understand you

But you said that you are unable to connect.

Is that for mobile?

Phone

Or how you connect to Amsterdam

The traffic reaches Europe without issues, but that's where the packet loss begins—I've sent mtr details to you.

I see it.

Tech needs to check your modem and your connection.

you are not understanding the meaning of problem

Can you explain it to me?

What is happening?

Do you have problems in connection?

What do you need to do exactly?

Packets are getting lost in Europe on Lumen's network, it's a persistent issue on the route to the KG zone.

This technical issue needs to be checked by the technical team.

I have nothing to do with

i need that you escalate this problem to Lumen

If you need to keep your appointment, that is fine.

Tech need to report that

So they will take care
