CM1000 Xfinity Download Speed


CM1000 Xfinity Download Speed

I switched out an xfinity router which gave me


    Download: 250 Mbps
    Upload    :   10 Mbps


For a CM1000. After the provisioning xfinity did everything worked pretty well after that, except for one thing. I've now been consistently getting very low download speeds.




So far I mentioned it to the xfinity representative that handled my provisioning and he said "give it 24 hours". I've also scheduled a technician to come in and upgrade the internet to gigabit internet, but I assumed that if I have low speeds now, likely changing to gigabit internet won't do anything to change the results. Also, from the Event Log I don't seem to be getting any T3 or T4 errors.


Here is the log

Re: CM1000 Xfinity Download Speed

This couple be a simple mix up I have seen it happen many times. I would contact the ISP and have them check your account they could of added your CM1000 and not removed the old modem from your account if so the CM1000 gets assigned a slow internet speed where the old modem has the 250mbps connection still on it.
