Netgear CM2050V connection type

I have been using a Netgear C7100V DOCSIS3.0 modem for several years and have found find that it consistently runs at about 10% of the rates that Comcast hypes to me. I borrowed an Arris SURFboard SB...

    Yes, criticals needs to be reviewed by the ISP and resolved with there help. 

    I see some correct and un-correctables but not really enough to be worried about. 
    Check all cabling and coas line fittings and besure they are snug. 

     

    Power is a tad bit high. MIght ask the ISP if they could lower it some maybe. 

     

    CAT5 IS NOT rated for 1000Mbps, You should be using CAT6 UTP between the modem and RBR and RBR to RBS if they are ethernet connected. IF you had the 8 series, then you would use CAT6A STP between the modem and RBR.

    I agree that cat5 is not rated for 1000baseT, but it seems that I sometimes get away with it on shorter lengths that need less equalization.

     

    I moved the Orbi next to the modem and connected them with the cat5e (not cat6) cable that came in the modem box. The multi-gig light on the modem indicates that it established a 1 Gbps connection with the Orbi (it did that inconsistently through the old wiring). That improved my download speed 10x over the C7100V, to 947 Mbps! This is in spite of the fact that the connection from the Orbi to the computer running the speed test is still the same old behind the walls cat5 cable. But if I update the router to a series 8 with a 2.5Gbps WAN connection maybe I'd be able to deliver that same rate over more than one LAN channel in parallel. That's something for another day.

     

    Moving the Orbi next to the modem didn't do anything for the upload speed, but I wasn't expecting that it would. This is more than good enough for now.
