Re: Help needed please CM1200 slowdown

What speed do you get with a pc/laptop directly connected to the modem? 

Your results were indicating you were going through the router. And the router could be the issue and not the modem. 

Especially since you're speeds directly off the linksys were hitting full speeds. 

And you  power levels look good on the modem (you didn't include the logs)

Re: Help needed please CM1200 slowdown

A screen snip is easeir to read when it comes to logs. 

What speed do you get with a pc/laptop directly connected to the modem?

Re: Help needed please CM1200 slowdown

it wouldn't let me post a screengrab and everytime I even tried to post that above I had to post and repost 6 times to even get it to stay on the forum. I don't have an ethernet port for my laptop.

Re: Help needed please CM1200 slowdown

Have the ISP check the signal and line quality UP to the modem. 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. 
Be sure your using good quality RG6 coax cable up to the modem. 
Be sure to power OFF the modem for 1 minute them back ON.
