cm2000 nighthawk
does anyone have any experience using the nighthawk cm2000 cable modem with their comcast business internet? it's not listed in the list of approved devices (https://business.comcast.com/help-and-support/internet/comcast-business-cable-modem-device-compatibility), but it's an even higher spec then the approved netgear devices. is it truly unsupported?
hi there, redstar918! thanks for bringing your gateway questions to the xfinity business forum! the nighthawk cm2000 is not certified for use on our network and won't be able to be activated with comcast business internet, sadly.  
  
we do support this modem with our residential services, however. so, if you are a residential customer, as well, and would like to purchase this modem for home use, you can! 
  
i hope this helps answer your question!
hey@searcher@gotchathanks for reaching out :) at the moment teacis not supported yet, sorry about that :/ you can find alldevices which support hifi in this list where you see the yellow “hifi” symbol. hopefullyteac will be soon in the list, so please make sure you check it regularly to make sure you don’t miss any update :) i think it’s too early to think about h.266.

in any case if it will be supported then you need new hardware. following cards have been verified

rcs\_r2ug-a2e16-a pcie switch

nvidia’a dgpu

intel82572ei nic

nec upd720200 usb3.0 card

asus usb3.1 card

moschip usb2.0 card

ocz ssd

ocz rvd400-22280-512g-a ssd

silicon image corp. 3132 sata controller

intel e10g42bt x520-t2 10gigabit nic card

sta… Your card is ok. There is interference between the router and your computer.  

  

1. The router or the PC may be "hidden" behind a metal cabinet, refrigerator, etc.  

2. Move router higher  

3. Microwave ovens and some cordless phones (not cellphones) that use 2.4GHz will interfere with the 2.4GHz WiFi signal.  

4. Point the router antennas in-line with the direction of the PC.  

5. Move the router closer to the PC. Do you have a laptop or desktop?


If its a desktop, do you have integrated (part of the motherboard) or discrete (card plugged into a slot in motherboard)  

networking controller?


Ususally Fedora (at least for the past several years) has had great support for ethernet controllers right 'out of the box'.


Have you used this particular machine with other operating systems and had the internet work correctly through through ethernet?


Did you create the Fedora bootable media yourself? Did you install Fedora yourself? Did you have the computer connected to the router through the ethernet cable while you did the install?


If you have a discrete networking card, you might need unusual drivers that the Fedora live media did not have.


If you did make the live media yourself, did you check the .iso file integrity before writing it?


Are other computers on the same network able to access the internet? It looks like all of these devices may be useful in the environment that you describe. My concern would be having enough POE to power the phones. Unfortunately, not all POE devices are made the same. You may only be able to power X number of devices off a POE switch when there are 48 ports available. You will need to be sure to understand and easily able to manage VLANs and COS/QOS. [Take a look at this blog entry](https://itknowledgeexchange.techtarget.com/it-trenches/voip-ipt-qos-cos-on-and-on-oh-my/). A call to a supplier like CDW would be a good thing. They are usually pretty vendor neutral and you will be able to talk to one of their product or service specialists to get a good understanding of a workable solution for your organization.


From djc1309 – I have used Netgear products for quite some time and have had very good luck with most of them. The recent releases of the FVS114 VPN router have had a higher than normal failure rate. I wanted to let you know that I purchased a NetGear RND4210 ReadyNAS Storage as per above and have not been able to get it going. I would stay away from this particular piece of equipment.


djc1309 hi@thebatswhiskersjust checking in on your half hourly usage issue?i think you’re also effected by the situation outlined in this topic, where i confirm:please be advised that there is a known issue effecting some customers, where half hourly usage information is not populating ontoonline usage graphs, despite good smart meter comms, and a populated monthly chart.if you haven’t already, we’d appreciated it if you could make oursupport teamaware of this, so a ‘case’ can be raised, helping us to identify the volumes of those effected. i assume your new router is wireless?

limited access with wireless usually means you don't have a valid ip address assigned. you need two things for a working internet connection. 1. you need a physical connection, known as layer 1 and layer 2. 2. you need a logical connection known as layer 3.

if you've got the limited access message that means your laptop has a working wireless connection at layers 1 and 2. what you don't have is the layer 3 connection i.e. an ip address.

there could be a number of reasons why this is happening. i would suggest that you start by powering your pc down - shut it off completely not just hibernate it or just shut the lid. next power down the router, pull the power cord out of it. let the router sit unplugged for about 2 minutes. power the router back up......wait about 2 min more. power your pc back up.

learn how to use the command line command "ipconfig". you access the command line via the accessories folder on windows. when you get the c:/> prompt - enter the command "ipconfig" hit enter. in the group of stuff on the screen you want to see an ip addess assigned to the wireless interface. when you get the limited access message the first thing you want to do is check to see if you have an ip address assigned.

if the above trick doesn't work, then i suspect there is something wrong with your network configuration on your pc. if you take your laptop to a starbucks does it work there? does the adapter get overly warm or even hot (check carefully) between the start of game playing and the wifi drop?

try using a usb extension cable to connect the wireless adapter to your pc.

then raise the wifi adapter up and away from the pc. 

reposition as necessary to determine if wifi service stabilizes.

may also help keep the wireless adapter a bit cooler. do you have transport rules in place that are used for moderation?  sound like one is in place and isn't properly configured.
