Netgear CG2100D
 

Hi guys,

Quick question(s) for you. :)

Do Virgin Media now push the Netgear CG2100D cable modem router for the new installs on 20Mb? One of our customers has this and I've never come across it before.

Netgear product page is here: http://www.netgear.com/products/serv...ys/CG2100.aspx

Naff-all support on it mind, no latest firmware for it.

Offhand, if anybody knows how to disable the SIP ALG on it that would be incredibly useful. :)

Kind regards,

TM

No the one we supply is a combined modem/hub called a vmdg280 which is built by Netgear for Virginmedia as per the link below.

Re: Netgear CG2100D
 

Not quite, it is a virgin branded one. https://www.cableforum.co.uk/images/...010/12/126.jpg

Re: Netgear CG2100D
 

Cheers guys. It was branded with Virgin Media firmware all over it, trademark stuff really. Next to unconfigurable, couldn't disable the SIP ALG in the web config and SIP over it completely fails to deliver the goods. Works as a cable modem, that's about it.

DOCSIS 2 n'all, so not even 50Mb users can take advantage of it.

Re: Netgear CG2100D
 

That's why they now have the superhub for 50 & 100Mbhttps://www.cableforum.co.uk/images/...010/12/119.jpg

Re: Netgear CG2100D
 

how locked down is that?

Re: Netgear CG2100D
 

It has embedded Virginmedia firmware onboard so any attempt to flash it would very likely kill it as it is primarily a modem a router second in this configuration.

Re: Netgear CG2100D
 

so how locked down is the router part of it ie how configurable is it?

Re: Netgear CG2100D
 

It's mostly a standard Netgear interface, so it's as configurable as that

Re: Netgear CG2100D
 

ta :)

Re: Netgear CG2100D
 

Configurable enough to turn off the DHCP and use it as a cheap standalone wireless access point? :P

Re: Netgear CG2100D
 

That access is not available so not possible as the is not a lot you can alter in the interface, which is quite deliberate on the part of Virginmedia and Netgear, buy one and you will end up in all likelihood with a doorstop.;)

Re: Netgear CG2100D
 

Are the superhubs any good, or are you still better off with a stand alone modem router combo.

just curious :)

Edit sorry the cold must have froze my brain cell :)

What I meant to ask was are you better off with separate equipment

Re: Netgear CG2100D
 

Seems like you and BenMcr have differing opinions of just what the standard Netgear interface is.

Does anyone have screenshots of it? Failing that I may be replacing someone's next week so I could have a dig around myself then...

Nobody has them yet except trialists and testers, so you won't get many opinions from the general public.

Re: Netgear CG2100D
 

I love the super hub. It works really well.

No issues at all.

Re: Netgear CG2100D
 

They have actually been in customer pilot for a few weeks, and available to new 50mb customers since the start of this week.

The front screen of the interface is VM branded though this is merely an overlay and clicking Advanced Settings takes you to a typically Netgear interface. Hope this helps.

Re: Netgear CG2100D
 

As I am the technical support agent I think that I can tell the difference between a standard Netgear router interface and a combined Netgear/Virginmedia interface.

The interface on the hub has both Netgear and Virginmedia branding once you log into the configuration pages and you then find that it has the modem power level pages and as with all Virginmedia modems you cannot change any of the modem settings due to it being locked down.

You then have the router pages which are of a similar layout to a standard Netgear page but with differences that Virginmedia required.

As part of our tools to support customers with this hub we have emulators which show us how each page should work with clickable links, so I have seen the actual pages.

You will find that due to it being a modem primarily that the will be very little that you can do with the hub unless you want to brick it, and no programmer is going to waste any time trying to write firmware for a modem/router when the are easier alternatives out there.

Re: Netgear CG2100D
 

I am using a Hub and yes you can switch off DHCP from the LAN IP section of Advanced.

Re: Netgear CG2100D
 

Maque, I did not say you couldn't tell the difference. I only stated you and BenMcr (also VM staff according to his forum title) have stated just about the opposite about the same thing.

As we already clearly disagree about what you can do with the device, I'm not going to argue the point further. What Mick's just posted directly contradicts what you say, and he claims he actually has the device while you have an emulator. Given I've already proved VM's "emulators" to be inaccurate and unable to show you the "actual pages" of your own website on several calls to support already, I'm not going to put much faith into yours.

Re: Netgear CG2100D
 

The is little point trying to do anything with that device as no one is going to write any firmware for it anyway.

As for switching off the DHCP in the hub we would not get into that as it would be Out Of Our Support Scope.

Re: Netgear CG2100D
 

Guess it's a good job I can write my own firmware and don't need your support then eh? Looks like the hubs (not superhubs, yet) are turning up quick on eBay as a lot of people have started getting them replaced, and VM don't seem to be asking for them back.

Re: Netgear CG2100D
 

Buy one then and please let us know how you get on.

Re: Netgear CG2100D
 

Soon as someone confirms if either the Hub or Superhub is dual-band, which I'm still waiting on...

Re: Netgear CG2100D
 

If you click on the original link in this thread you will go to the webpage of the router the hub appears to based on and that only has Wireless: 802.11n in the 2.4 GHz band and not 5 GHz which will be the same with the hub.

Re: Netgear CG2100D
 

And then in the next post you say that it's different, which presumably means it's specifications may also be different? That said I wasn't expecting the hub to be dual-band, though someone has mentioned the SuperHub - I just have no confirmation yet.

Re: Netgear CG2100D
 

I have no complaints with the Hub.

Admittedly I only use the router to run a small home network consisting of a wired Desktop, a NAS device running a continuous backup and a laptop.

I have the network configured to fixed IP's and consequently have DHCP switched off. Both machines are port forwarded for torrents although I rarely use them.

I have seen up to 80Mb/s across the network on times which definately outperforms my old Linksys WRT54G2.

I find I can pull the full 20meg wired or wireless.

As stated I am not a torrent hog so have not much experience but have used it a few times with medium sized swarms without any problems whatsoever.

IMO it's a great bit of kit. :)

Re: Netgear CG2100D
 

I rather doubt it will be 5GHz either.

Re: Netgear CG2100D
 

Super Hub has a 2.4Ghz mode, and a 5Ghz mode.

Re: Netgear CG2100D
 

Do you actually have one and if so post a screenshot of the page for us please.:)

Re: Netgear CG2100D
 

Yes I do have one. Not at home at the moment but will gladly oblige when I am.
Just to substantiate though, the new wireless adapters that accompany the Super Hub also support dual band.

Re: Netgear CG2100D
 

Thanks for that, I know the Superhub uses a different dongle than the routers, thanks in advance of posting the config page.:)

Re: Netgear CG2100D
 

There's been an emulator for the Superhub for a while now, you could just have a look at that. But still, for the curious ones....

And FYI - there's a firmware update planned for the HUB that will allow you to disable the "router" side of it and make it a bog-standard cable modem, for use with your own router (I believe it's listed as "gateway mode").

EDIT: I have no idea how that image ended up so massive (sorry!).

Re: Netgear CG2100D
 

I should think so too!:D:D:D

You could've done it like this.

Re: Netgear CG2100D
 

Yup, that's exactly what the interface is. Very much VM RED and nowhere near Netgear BLUE.

There is no option in the settings to disable the SIP ALG, but the customer successfully sorted the call problem by disabling the firewall. Go figure, a bricked router that you have to make insecure to do SIP correctly.

Re: Netgear CG2100D
 

I had issues with utorrent with the hub but fixed it by disabling ipflood in firewall settings
