High Latency 20s - CableMax - Model CGA6444VF

23hp — Wed, 09 Mar 2022 06:37:48 GMT

Hi, I get this new network account 1.5 weeks ago for my new apartment.

Customer number. ***

CableMax 1000M, device model is

The network quality is far worse than my previous Vodafone100M one in another apartment. and the problem does not exist when I connected to my mobile data or neighbor's WIFI,

The problem is, frequent long loading,

Video call, mobile call via WIFI disconnected every 2 minutes. my friends complain my network is too bad to see and hear me.
online game is not possible
Twitter doesn't show images and videos, loading takes around 20 seconds, happens every 5-10 mins,
Google Translate slow response(20 seconds), especially for real-time translate
Netfilx on TV is loading sometimes, TV use LAN/cable, video works better as it is not real-time service, but if I use mobile data or neighbor's wifi -> no latency

The above problems happen on all my devices/phones. disappear when I change to mobile data or neighbor's WIFI.

I've tried cutting down router power for 1 hour, resetting the router, reconnecting the cable, re-install the cable socket. none of them work.

Please suggest what I can do, or how to cancel my account. thanks a lot.

FYI: I upload the error screenshot to the comment below.

Hi Moni,

The problem happens every day, any time, since I open this new network account, not only a specific day,

Hello 23hp,

then send an actual ping plotter. But please send the complete history. Unfortunately, the target was missing in your first one.

Hi Moni,
I didn't quite get it, you mentioned:
complete history. Unfortunately, the target was missing in your first one.

May I have an example?

Please show me detailed guidance on how to achieve this.

I can provide you lots of screenshots, videos showing the network issue. it really bothers me.

Re: High Latency 20s - CableMax - Model CGA6444VF

Moni_GK — Wed, 09 Mar 2022 12:55:12 GMT

Hello 23hp,

have a look at your first ping plotter. It is not complete. You could scroll down the page to make it complete.

I need that please.

Greetings Moni

Die aufgeführten Links sind informativ - keine VF Produktionen - und Wert gesehen zu werden.

Bei schlechten WLAN Empfang, schaue dir dieses Video an.

Erklärung zu Docsispegel, schaue dir dieses Video an.

Vorgaben zum Docsispegel hier

Hast du eine Fritzbox und du bekommst keinen 1Gbit/s Speed, prüfe deine LAN Geschwindigkeit, schaue dir dieses Video an.

Enthält dein Routerlog einen Eintrag Utopia, oder ein Blockieren bzw. stehen Drops von WAN/LAN an?

Probleme am Anschluß können nur unter Verwendung einer LAN Verbindung beurteilt werden.

Wichtig: Den kompletten Docsispegel Down- und Upstream posten.

Speedtest: 5 (fünf) Speedtests von speedtest.net als multiuser mit LAN.

5 (fünf) Speedtests von speedtest.net als singeluser mit LAN.

Multimode baut 4 Verbindungen zum Speedserver auf, Singlemode nur eine.

Nur die "Resuls" aus den 10 (zehn) Speedtests im Singel- sowie Multimode sind von Interesse.

Ein einzelner Speedtest ist nicht aussagekräftig!

Der von VF empfohlende Pingplotter ist eine 14 tägige Test Version und kann max. 10 Minuten aufzeichen. Die Vollversion kostet $40.

Ich empfehle den kostenlosen pingtracer für M$ User, zip Datei downloaden, entpacken und starten. Es können Langzeittrends erstellt werden, mit der Taste „Bild ⬇“ können alte Daten abgerufen werden.

Well done. LAN and IPv6 is working well.

There aren't any drops in IPv6 for the target nor for the VF Servers. The losses somewhere between are to ignore, due to firewall policies of some network devices.

Are you willing to perform the same mtr test for IPv4?

I do assume the command will be mtr -4 heise.de. So it would be for Linux.

If so, please post the result.

If you notice a different amount of drops as seen in Ipv6, stop here.

When successfully done repeat the same test with WiFi. To do so your device need a good signal strength.

Kieferer — Thu, 10 Mar 2022 12:19:55 GMT

Nicely done, even again IPv4/6 Tests in one Post. Thanks

Conclusion LAN/WLAN Test IPv4: There are small Packetlosses in IPv4 at the VF Gateway - directly after your router - visable. This shouldn't be. The worst ping at the Gateway have been 311.8ms, the avg is OK. Nevertheless there have been more spikes occurred since the sigma is still 57.4 even with 1644 samples.

If you are for a further investigation interested use the pingtracer for 30min, pingplotter is limited to 10 Minutes.

At the Target there isn't any PL noticeable. So everything fine for the Target.

Conclusion IPv6 Test: Looks better. There are less spikes, see worst and st.dev.

In LAN/WLAN aern't any PL to the target "heise.de", neither in IPv4 nor in IPv6.

So I assume something fishy either with the router Firmware or android.

Is there a log entrance called Utopia, if so, this would be a cause for your troubles.

If you use Android devices, if so, turn off - as workaround - Private DNS in your android device. Not sure if this router can handle DoH, DoT.

Drop outs in a frequency of 2 min are not seen.

Twitter use a IPv4 address VF natively IPv6

Google Translate, 20sec. Yes sometimes me too. Try deepL as reference. This maybe not a solution, but better as google. At moment the peering to google doen't look so good and I won't ask VF why.

Blue Bars are PL's

google.com 30 Hours

Online game, special topic. I'm far too old for this

You have to specify.

Do you have a 2nd router?

Ca you post a screenshot done from this site. I'm interesed in the Upload/Download graph

"Netfilx on TV is loading sometimes, TV use LAN/cable, video works better as it is not real-time service, but if I use mobile data or neighbor's wifi -> no latency"

Maybe better to describe it a bit more in detail.

Hey Kieferer,

It's not the problem of my android phone, I'm a senior software developer. that's why I can dig so deep.

Thanks for provide the clue.

I think the problem comes from the router firmware, casue the WIFI not working properly.

I can eaily reproduce my issue via twitter or google translate. so I tried:

1. connect to LAN, issue gone

2. connect to SSID Homespot from same router, issue gone

3. connect to WIFI from a sub-router, issue gone

4. disable 2.5GHz or 5GHz in vodafone router , problem still happen

It makes me recall my last apartment, all tenants has a sub-router connect to Vodafone router(same model as mine), as the wifi from it is not reliable. I belive this is a known issue for a long time.

I require a full refund for the interet account, include the fee for turn device back.

I opened it 2 weeks ago, but takes half of the time troubleshooting and fix it. it cost me more than this vodafone account take.. My life shouldn't spend on a known issue.

Please help, thanks
