CM500 - Xfinity says the weak signal is due to my modem? I need to update the setting of the signal?

Hi All,

 

I moved house and after about a month the wifi signal gets weak a few hours after a reboot of the modem and router. I spoke with xfinity and they said they have trouble shooted everything from their side and that the problem is my Netgear CM500 modem. Apparently I need to update the settings?

 

Does anyone know what the problem is?

 

Thanks

 

GrahamJohn

    There's no settings to update. 

    do you have a screen snip of the cable connections page and the modem logs? That'll show us the signal strenght. 

    Xfinity is great at saying "its not our lines" for the first round of troubleshooting. 

    If you do have any splitters, amplifiers, or signal attenuators in the coax line, i'd recommend removing them. 

    Check the coax for kinks, bad/cheap connectors, extended runs

    Prefereably move the modem to right where the coax enters the home to prevent the wiring internal to the home being the issue.

      Thanks Plemans,

      I've attached the speed test. It seems fine for a while only when the modem and router are reset.

      Xfinity loves the fact that I know nothing about this stuff.

       

      Thank you for taking the time to help.

        What speeds do you pay for?

        do you have a screen snip of the cable connections page and the modem logs? That'll show us the signal strenght. 

        Not the speedtest, the cable connections page.
