Question Wired Cable Modems That Can Interface With Linux


I have for many years been using a Netgear DG834 wired cable modem.In order to access this modem to adjust settings I have to use the Windows Vista OS on my dual boot system. This is because the installation software supplied with the modem could only be installed on a windows system. At some point the hardware running the windows system will die. As I use Linux Ubuntu for home office use exclusively I would prefer to replace the modem with one that can be installed and configured with Linux. I wish to remain a cable system user and not migrate to Wi-Fi. The question is therefore are there any Linux compatible wired cable modems available in the UK that can operate with Linux without needing Windows to set it up? Thank you.

A few things

1) The DG834 is an ADSL modem/router, it's not a cable modem.

2) I don't really understand your statement, "I wish to remain a cable system user and not migrate to Wi-Fi". Do you mean you want to use a wired connection rather than wireless? "Cable" implies "cable modem", which you don't have. Why don't you want wifi? You do know you can just disable it if you don't want to use it, right? Just because the router has wifi doesn't mean you have to use it. You also don't need your router and modem to be the same device. Did your ISP provide you with a DSL modem? Does that also require PC software? You can just stick your own wired router behind it if you want.

3) It doesn't look like that router requires any PC software. From what I can tell, it uses a standard http interface like all other routers, which is accessible from any device on the LAN regardless of OS:

I was going to say the same thing about http setup. Give it a try, and let us know how you get on.

It seems to be common for ISPs and/or router manufacturers to provide 'setup' software because their customers expect it, but often all it does is provide an alternative route to features that are available without it.

If there are features that really need special software to get at them, then you need either a new modem, or better firmware for your existing one. It looks like at least some versions of the DG834 are supported by OpenWRT. Admittedly this is probably overkill, but you might find that installing open-source firmware on your router is easier than keeping a Windows box alive, and it would be cheaper than a new modem.

they all work from a web interface

even my Comcast Xfinity works
( now i do have to disable the GARBAGE!!!! thing they call a "firewall" )
blocks ONLY good programs
tor
ktorrent
freshclam -- YES it BLOCKS THIS!!!!
and so on

a check box for
Code:
Block http (TCP port 80, 443)
Block ICMP
Block Multicast
Block Peer-to-peer applications
Block IDENT (port 113)
Disable entire firewall
the max. blocks
Code:
    HTTP and HTTPS (TCP port 80, 443)
    DNS (TCP/UDP port 53)
    NTP (TCP port 119, 123)
    email (TCP port 25, 110, 143, 465, 587, 993, 995)
    VPN (GRE, UDP 500, TCP 1723)
    iTunes (TCP port 3689)
blocks ' itoons 'and DNS!!!!!

I've a "SuperHub"cable modem supplied by Virgin and the HTML interface works fine on Linux -- I've configured port forwarding to my Pi and fixed IP address assignments for my machines with no problems from a browser on Linux.

Thanks for all the responses. Apologies for being cross eyed and not identifying the device correctly, it is a Netgear DG834 Combined ADSL2+ modem and router. It plugs into my broadband enabled telephone socket and is connected to my computer by an ethernet cable. It is the ethernet cable connection I wish to stay with and not connect by wi-fi. I am anticipating a change in ISP and it seems that most of the prospective new ISPs supply their own routers with wi-fi connections. I am encouraged by the number of respondents who advise that all modem routers can be accessed through the browser, however it seemed that mine could not. I had tried http://192.168.0.1 and some others such as http://modemlogin but received unable to connect or in the case of http://192.168.1.1 a timed out message. Curiously on attempting this approach on a later occasion the http://192.168.0.1 gave me access. Anyhow it seems my fear that modem routers in general could not be configured with Linux was unjustified.

Sometimes one needs to use "https://" instead of "http://" or it is not possible to connect to the web interface.

I've used at least one where local access to the http setup could be disabled from within the setup. The only easy cure is a hard reset of the router. Come to think of it, it sometimes took two or three attempts to get it to respond at all.

Earlier this year my ISP-provided router stopped routing, so I called the ISP and their support rep tried to talk me through the procedure to allow them remote access. Unfortunately, their router firmware had changed since I got mine, and the script she was using didn't match the menus. Eventually I found the setting she wanted, which allowed access from LAN/WAN/Both. Following the script, she told me to set it to WAN, then we both wondered why the router suddenly stopped responding!

Of course, it had only stopped responding to me on the LAN (just like I told it to...) - I should have set it to "Both", which I figured out about thirty seconds later.

I reset it and regained access, but by then the rep had quite sensibly decided to give up and send me an up-to-date model.
