NightHawk CM1200 only getting 30 mbps hardwired.

NightHawk CM1200 only getting 30 mbps hardwired.

I tested my old Motorola modem and getting 130 mbps but when I register netgear with xfinity I only get 30 mbps. All default configurations. What could be the issue? I am switching To netgear because my plan supports 500 mbps but my old Motorola only supports 130.

Do you have more than 1 device connected to the cm1200 or do you have a router using WAN aggregation?

Re: NightHawk CM1200 only getting 30 mbps hardwired.

I have google Nest Mesh setup but I plugged just my laptop direct to modem and only getting 30 mbps. No other devices hooked up. If I swap out with my old one I get the 130 direct from Ethernet port.

Re: NightHawk CM1200 only getting 30 mbps hardwired.

Should I have hooked plugged my Ethernet into port 3/4 instead of 1/2 since I only have an ISP or 500 mbps?

Re: NightHawk CM1200 only getting 30 mbps hardwired.

Only connect 1 device to the CM1200. Connect it to port 1. (google mesh doesn't support wan aggregation as far as I know). 

 

Also, log into the router and click on the cable connections page. Get a screen snip of all the info and post it back here. 

also do this for the modem logs. This helps us check the signal back to the ISP. A bad signal could cause issues. 

You can also check with the isp to make sure they provisioned it right. I've had the wrong speed provisioning sent before or the wrong file (different device file)

Re: NightHawk CM1200 only getting 250 mbps hardwired.

Hardware Version 1.01
Firmware Version V2.02.05

No logs only getting 250 mbps on 600 mbps plan on Ethernet

Is there a starting frequency I should set for xfinity?

Re: NightHawk CM1200 only getting 250 mbps hardwired.

Before you said you were only getting 30mbps. 

Now you say your getting 200 mbps? 

did you change something? 

And the modem does have logs. https://kb.netgear.com/30008/How-do-I-obtain-the-event-logs-from-a-NETGEAR-cable-modem-modem-router

 

What device are you testing on? 

have you tried a different device?

Re: NightHawk CM1200 only getting 250 mbps hardwired.

I found the logs after I rebooted this morning.  Xfinity did not open up all the ranges or something outside my house that is why I was getting 30 that is now switch to 200 but we tested with their hardware and they were getting 450-475 from their modem.

 

I was tested hard wired to my macbook pro.

Re: NightHawk CM1200 only getting 250 mbps hardwired.

Let the modem function for a bit (so we have more info) and then get a screen snip. Please use a screen snip as the values/info tends to be easier to read for logs and cable connections pages.

Also, check with xfinity to make sure they properly provisioned it. When you say they "didn't open up all the ranges" its usually a tech says to cover for something else. Kind of like a mechanic saying your muffler belt was loose.

Re: NightHawk CM1200 only getting 250 mbps hardwired.

Just like they sound. They tend to mean the power is fluctuating and exceeding their limits. Its common when you first connect/power on the modem but let it run for 24 hours and then pull the logs. If its happening throughout the day, then the isp needs to recheck the line.

Re: NightHawk CM1200 only getting 250 mbps hardwired.

How would I know if they provisioned my hardware correctly?  I can't remember the termenoligy the tech said but he was on the outside of my house in their xfinity boxy making the changes.  It was like it was not using all the channels but he said he opened them all.  This modem is a 32 x 8 where their hardware is a 16 x 8.

Re: NightHawk CM1200 only getting 250 mbps hardwired.

All your current channels are locked. 

And the logs take some time to run throughout the day to see if power spikes/drops. 

They might have had a signal attenuator on the line or line block. 

The provisioning is something they send to the cm1200 with the firmware when they set it up for usage. I've had them send the wrong provisioning file before that caused slow downs. Its why I'd recommend having them re-provision it. 

I'd also recommend to make sure your testing directly connected to your pc and try this site: https://speedtest.xfinity.com/

Re: NightHawk CM1200 only getting 250 mbps hardwired.

Work with the ISP on getting the line and single working. Give this information to them. They need to make sure the line and signal up to the modes is working well. There is new FW for the CM1200 so be sure to ask your ISP about this. Have the ISP re-send the config file to the modem as well, then power OFF for 1 minute then back on.

It was the CM1200.  I went to a CM700 as I only have a 600 mbps plan and now I am getting 670.  All is good.

Re: NightHawk CM1200 only getting 250 mbps hardwired.

are you still seeing issues with CM1200 getting 600 Mbps?

please let us know.

 

30 Mbps sounds like your device is provisioned with default (wrong) config file.

 

Please re-activate and let us know.

give me the CM MAC as well.
