My modem, Netgear CM500 isn't giving the correct speeds.

Question

Hi everyone, so recently I purchased a CM500 for my internet plan for optimum. I was getting a little 300 download and 30 upload. Ever since I switched a couple days ago my speeds have been just awful ranging from 10-25 mbps download and 1 upload. I called my ISP and they said that it didnt seem to be anything on thier side. I really dont know what the issue is, some help would be really appreciated. I have the 300 optimum plan by the way if that matters, I know this modem is capable of 300 mbps download as I read before i bought it.

Are you speed testing with a wired PC directly connected to the CM modem or is there a wifi router in between the modem and your PC?&nbsp;

There is a wifi router between the modem, and I am running wired as well.&nbsp;

Speed test with a wired pc connected to the modem directly...&nbsp;What is the brand and model# of the router?

UncleWashington · Answer

The router I have is TP-Link AC1750, Archer A7. I just tested directly to the modem and interestingly enough it gave me the same speeds im getting already.&nbsp;

Try testing a different wired PC...Please post a copy and paste of the modems connection status page.Have the ISP check the signal and line quality UP to the modem.&nbsp;Be sure the ISP provisions the modem correctly.Be sure there are no coax cable line splitters in the between the modem and ISP service box.&nbsp;Be sure your using good quality RG6 coax cable up to the modem.&nbsp;Be sure to power OFF the modem for 1 minute them back ON.https://community.netgear.com/t5/Cable-Modems-Routers/General-info-and-Troubleshooting-for-Cable-Modems/m-p/1530376#M12853
