So the long of it is, I got a new desk that required I move my modem. So I unplugged it, set it up on top of the desk replugged in everything. Coaxial, ethernet for pc and gaming console. But now not only is the device not getting picked up for wifi, but even hardlined only my pc is picking it up and it's at a severely reduced speed. It's like the modem has an internal chokepoint set up now. I have done a several resets and factory resets to no avail. Can't figure out where things went **bleep** up in the five minute turn around time.

A couple things. The CM1150V doesn't have wifi. Not sure what your router is but the cm1150v doesn't have an integrated router. Also, if you only unplugged it and moved it, I'd be checking out the coax cable, connectors, and wall outlet. it wouldn't be the first outlet that had the coax cable loosened or pulled out far enough to cause signal degradation. Do you have a scren snip of the modem cable connections page? that lets you check signal quality/strength. What router do you have connected to it?

Your description makes it sound like you do. the CM1150V has more than 1 ethernet port but most ISP's only support 1 device connected to it. Meaning they only give 1 assigned public ip address. If thats the pc and not the router, nothing else will work. So make sure to go modem---->router----->devicesdon't connect anything to the modem other than the router. after reconnecting things. reboot the modem and router.

who's your ISP? Its rare to find one that will assign more than 1 public ip address unless its a business class line or you pay for the extra IP addresses. What connectivity issue where you having between modem---router? the one we're discussing now? did you have a screen snip of the modem cable connections page?

I had them open/assign to the other ports when I called. Though that could've changed. I was having connectivity issues between the modem and router, so I just said **bleep** it and asked them to open them all so I could hardwire them all too it. I see, I see. So make sure just the modem and router are hardlined, reset them both, and then just wait for them to reset?

Cm1150v, moved 1 foot higher. Now barely working.
