Netgear C3000 - Not exceeding 50 MBPS

I have been using Netgear C3000 model router/modem combo for my internet. I was recently got into 200 Mbps plan as part of moving from one location to other. Earlier i used to have 100 Mbps plan. 


I tried doing a speed test using ethernet cable and suprised to see my router combo getting only at 35 Mbps. I tried repeating the speed test at multiple instances and it didn't increase much.


My question here: Is this model C3000 don't have capability to handle spectrum mentioned speed ? Model spec has all details to support upto 300 Mbps. Please advice.

    The theoretical top speed is assuming you get the full ~38mbps throughput across all channels with no errors/retransmits.

    But this is not running in a clean lab environment and all that bandwidth is getting shared with others.

    So in reality, you are more likely to get roughly the equivalent of around 1/4 to 1/3 of that when the network comes under higher loads.

    That modem is limited to only 8 downstream channels, so you are at risk if dropping below 100mbps usable throughput when the node comes under decent loads.

    Need to move to at least a 16 channel model to give yourself more headroom. If you are on a Spectrum plan (not legacy TWC and such), then you can get a modem through them at no charge. Just be mindful of their $5 wifi charge if they are managing wifi on their device. If you provide and manage your own wireless router, you can get that fee removed.
