New C7100V took a nose dive - slow DL speed/normal upload

Model Number: c7100v

Firmware: V2.01.33

OS: Mac High Sierra v10.13.3

 

Hi guys. I purchased the Nighthawk c7100v dual modem/router so I could stop paying the rental fee through comcast, and it works with the triple play that we have. We have a one story, 4 bedroom home and I've never had an issue with coverage or speed with comcast's Arris dual modem/router that we used for years.

 

My speeds using comcast equipment were 150 Mbps down/5 mbps up. Nothing special, but it does the trick.

 

I installed the Nighthawk, called comcast and activated it, checked connectivity and it was working fine. Very similar speeds using the speedtest.net. That was March 17th, last Saturday. On Sunday, March 18th, I noticed the internet was lagging quite a bit. I checked speedtest and it ran a 6 mbps download/5 mbps upload.  I restarted the Nighthawk and tried again, but same result. I am lucky to get 10mbps.

 

I'm not using another router, the placement of the Nighthawk is above anything else, not being blocked by metal or a wall, it's in the living room out in the open.

 

I called comcast and they are sending a technician, but I'd like to try and fix it myself in case it's something you guys can help me with.

 

Thanks for taking the time to read this, hope to see a good answer on here soon.

 

Have a great night!

    Are you getting the slow speeds just on wifi and not over the wired connection?

      Hi DarrenM,

       

      I checked my wired connection through my xbox one (my laptop doesn't have an ethernet port) and it was running 120mbps. I changed some of my channels around on both the 5 and 2.4 ghz bands, and I saw improvement on the 2.4 ghz which ran 70 mbps, but my 5 ghz was still running at 10 mbps max. Upload speeds remain consistent at 5 mbps.

       

      I had a comcast tech come out today and check all the cables, outside connection, etc. He was getting a solid signal on all of his tests. He re-provisioned the modem and we're still running slow speeds. I can post all the logs in here if you think that would be beneficial.

       

      Since it's not Comcast's equipment, the tech told me there's not a lot he can do except for reset it, re-provision it, and test the conncections outside. I'm upset that this modem isn't working out of the box, but I'm willing to figure out what's going on, I think I just need a little help from all of the smart folks on this site.

       

      Thanks for taking time to read all this, I really appreciate it.

        Yea you can post the logs and the power levels of the modem may help find a issue that is happening.
