Regelmatige internet drops

[svenn0]

Hallo

Wij ervaren  al lang regelmatige internet drops. Het probleem is zowel bekabeld als via wifi.

De connectie van de apparaten met de modem is stabiel, ook via wifi.

Vooral over wifi merken we dat de latency  zeer hoog wordt, bijvoorbeeld tijdens browsen op het internet dat pagina's heel traag of niet laden.

Kan dit mogelijks een probleem zijn met de dropkabel?

De eventlog van de modem geeft continue volgende berichten:

@svenn0  eigenlijk zou je dat niet willen weten wat het betekend maar ik kan je er een antwoord op geven hoor. 

Het betekend heel simpel er is een fout , een event , op die frequentie op dat ID meer zegt dat niet. Dat zegt ons ook niks maar een technieker weer wel. Maar hier kan je er alles eens over nalezen:

@patrick2 

Ik heb die ook hoor af en toe.  Denk dat iedereen ze heeft en dat het niet zo er is

De eerste paar zinnen van de summary in je link zeggen dat je modem in zo een geval on-line blijft

Summary

Partial Service can be a tremendous advantage for cable operators because a DOCSIS 3.0 cable modem will stay online even if one or more of the upstream bonded channels goes offline due to RF impairments.  The subscriber will not likely notice any service disruption with the exception of a short disruption of about 15 seconds  when the CMTS and cable are attempting to re-range on the impaired channel.  The subscriber may also notice throughput issues if the DOCSIS upstream is in an over-utilized scenario and they have fewer upstream channels to use based upon their service tier.

A DOCSIS Partial Service outage should not be considered a permanent band-aid to resolve RF plant issues, but a temporary measure to keep the subscriber online while the impairment is identified and resolved.

@Gregory  ik weet dat iedereen die heeft. Ik weet ook dat iedereen modem events heeft want een netwerk kent nu eenmaal up's en down's. Zou anders niet best zijn. Denk zelf dat iedereen zich hier op blind staart en denkt ik heb problemen maar dat hoeven niet altijd problemen te zijn. Natuurlijk als je internet elke 5 minuten uitvalt en daarna pas verbinding is ja dan kan je verder kijken maar die logs....zeggen totaal niks. Als er geen logs instaan zou niet best zijn vrees ik.

Uit m'n hoofd: SNR moet hoger zijn dan 34, TX max. 47 en RX tussen -4 en +17.

Ik zelf heb ook enorm veel van die events en uitval op de modem maar krijg geen antwoord van Orange.
