UBC1318ZG reboot regelmatig

[Jur3]

Op 17 mei j.l. is er bij mij de AOP vervangen en is er een UBC1318ZG geinstalleerd. Sinds installatie heb ik er last van dat het internet soms uitvalt, maar sinds afgelopen zondag is het ernstig en tot wel 10 keer per dag. Vanmorgen al 2x en het is nog niet eens 8 uur. Op moment dat het internet wegvalt dan is het modem aan het herstarten.

Ook heb ik 1x meegemaakt dat het modem ethernet poort 1 uit had geschakeld (ik draai in bridge mode). De 2 lampjes bij de poort waren uit en enige remedie was een power-cycle.

Voordat dit modem is geinstalleerd heb ik nooit ergens last van gehad en de hardware die erachter zit is niet verandert. Ik heb getest met andere netwerk kabel en een andere router erachter, maar dat maakt allemaal niet uit.

De modemwaarden zien er volgens mij goed uit. Het valt me wel op dat het modem alle logs kwijt is na reboot/power cycle, althans ze zijn in de UI niet beschikbaar.

Voor mij is er op dit moment maar 1 conclusie, de hardware van dit modem is gewoon niet goed.

Kan dit modem omgeruild worden?

Hierbij de logs van het modem:

[Jur3]

Dank allen! Ik zal de bevindingen n.a.v. bezoek storingsmonteur melden.

[Jur3]

Gisteren is de monteur geweest. Volgens hem leek de connector niet helemaal goed gekrimpt/bevestigd op de groene kabel waardoor mogelijk de mantel geen goed contact zou maken. Hij heeft 'm afgeknipt en vervangen. Zelf kon ik aan de afgeknipte kabel/connector eigenlijk geen probleem ontdekken.
De monteur heeft het signaal gemeten en alle waarden zagen er goed uit.
Voor de zekerheid heeft hij de UBC1318ZG en de kabel tussen modem en splitter vervangen.

Ik ga het even een week aankijken en meld me dan weer. 🤞

Voor de volledigheid. Hierbij nog even de modem waarden en logs na 21 uur uptime.

Dat ziet er goed uit. Het OFDM kanaal geeft keurig nul uncorrectables aan. Dit behoort zo te blijven.

Dus het vervangen van connector en modem heeft het reboot probleem opgelost. 😀

Zelf ben ik van mening dat het probleem in het modem zat, aangezien (1) de modemwaarden voor/na vervanging (ongeveer) hetzelfde zijn, (2) verbeteren van signaal (door verwijderen van splitter) geen enkel effect had op reboots en (3) de vorige connector in mijn optiek prima op de kabel gekrimpt zat. 

Het oude modem heb ik hier nog liggen, maar ik heb geen behoefte om dat verder te gaan onderzoeken en daarmee (3) uit te sluiten en mijn mening bij te stellen 🤓   
Als Ziggo dat wil doen (of er iemand anders mee wil lastig vallen...), dan kan ik het opsturen en ontvang ik graag instructies hoe dat te doen. Anders gaat het naar de afvalscheiding. Laat maar weten.

Bedankt allemaal voor de hulp!

Mooi dat het probleem is opgelost.

Een moderator kan je een retourdoos voor het "oude" modem toesturen. Het moderatie-team is ingelicht.

[anoniemforum]

je kunt het oude modem ook in de doos van de Ubee retour sturen
