I would like to connect 2 PCs to my cablecom modem via 2 ethernet (RJ45) cables. The modem that I got from cablecom has only one socket.

Does anyone know if cablecom has modems with more than one RJ45 socket? Or where I could buy a modem "cablecom compatible" with more than one socket?

I could not find it in their online shop,still waiting for them to answer my email,no English on phone.

Obviosuly one could get a router and solve the issue, but I am keeping this as a last resort, better would be a modem with 2 sockets.

Thanks!

A 4 port broadband router will do the trick - better if the router was wireless. NAT ( Network Address Translation ) is required to allow more than 1 PC to pass through, hence a broadband router is required ( do not get an ADSL router! ).

4 LAN ports --> 4 PCs / devices
1 WAN port --> Cablecom Modem's Ethernet Port

jrspet, thanks for the prompt reply. You mean something like this?

Now, a naive question...it does have a socket for Cablecom's Coax broadband cable, which would be the "input"? Or am I missing something?

Yes, in fact I have that same box.

The coax from your Cablecom socket on the wall goes into the back of your Cablecom modem, not to the router.

From the CC modem, an Ethernet cable goes into the Router's WAN port.

Some alternative products available locally:

Asus
Top Price etc.

Coax from the wall socket ...



goes into the coax connector of the Cablecom modem

Ethernet socket of the Cablecom modem connects to the WAN socket of your broadband router. In this case, to the Netgear's Yellow coloured port.

Man! many thanks for the much detailed explanation and information, its clear now

cheers

Hi,

Ive the same problem with my cablecom modem. Ive my own wireless modem but cannot connect it because it is meant to be plugged to a telephone cable and not to a coax. Is there any adaptor I could use?
Thanks!

I believe you are talking about a DSL Modem, can you send a picture of it or name its model ? is it something like this

And by the way you can buy a very cheap wireless modem from the online shops - I had a colleague bought one last week for 26 franks including the delivery.

Like this Wireless modem

All the best.

some ADSL modems can be configured to be in router only mode. In fact most can, just that some require tricky (telnet) ways of achieving this.

as far as I know, cablecom actually allows for 2 dynamic IP addresses per subscription, which means the cheapest solution would be to get a basic switch.
So, something like this

Ok I checked it out - 2 dynamic IP's for anything on plan 25 and above.

this is a BAD thing. If you're not a net security expert and know your way around firewall settings, plugging any PC direct to the internet will get you infected faster than you'd ever believe. *Always* use a router/firewall box between your computers and the internet. The cablecom modem doesn't cover this functionality, and the average PC firewall product has enough flaws in it to just make management a nightmare (and they're just as open to infection as other Windows software).

Also, ADSL modem/routers don't have an RJ45 port as the WAN port (internet facing) but a RJ11, so they're unusuable as routers for cablemodems unless the software actually allows to designate one of the switch ports as the outbound port. It's usually a waste of time.

Rubbish. Did you actually think about and then read what you posted ?

Any modem xDSL or Cable with LAN ports is automatically a router, and automatically using NAT. This in itself will stop inbound connections from dubious sources, and unless port forwarding is enabled to services running on the LAN, there is no way WAN unsolicited connections will get through.

Secondly, the Cablecom modem/router does have a basic firewall function. Most Netgears et al will have basic SPI.



Lastly, Windows Firewall and Defender is on by default and does a very good job at protecting from dubious / malicious incoming connections. Most infections will come from Web browsing (Drive-by), Torrent Downloading , HTTP downloading etc which means these connections have already been allowed through the firewall either through uPNP or port fowarding and triggering. Most home firewalls do not support content inspection or UTM so don't even try to recommend one as appliances with this kind of functionality cost many hundreds of bucks and require licensing to continue using these features.

PC software firewalls all do a very good job and you should not be deterring people from using them, they are essential when using the Internet or installing software from unknown sources.

Having an RJ11 port on the WAN side of a vDSL cable modem is irrelevant to whether the unit can route or not. Most modems have RJ45 ports on the LAN side and are therefore routers. Very few are sold without multiple LAN ports. Even if the modem was not plugged into the WAN side , it would still function as a router. Try it and see.

Huh? Computers getting infected just by plugging them in is baloney unless your system is never patched and you don't use local security software.

1. By far most computers get infected because the user downloads something he / she shouldn't. No firewall in the world is going to protect you from that
2. using local security software (such as Norton Internet Security or Norton 360) is more than sufficient.

You were right of course, if it wasn't for the fact that...

...there is no such thing as "the" Cablecom modem/router. They use many different models (click here to get a hint). Some probably do have router/NAT functionality but I know that the one I have does not (or at least it's not activated). It also has only one LAN port.
When I attach a computer directly to the cable modem I get an IP address out of Cablecom's pool of addresses and not one of the 192.168.* addresses you get in typical home network.

And that's basically what happens once you decide to reinstall your PC from that 3 year old recovery DVD that came with it and then connect it to the net without router/NAT/firewall in between to run Microsoft Upgrade? Good luck with that...

Correcty - this is by default. but its a setting one can change.

Which is the case for most modem/routers.

Which is where I fail to see how its a waste of time. Mine is an ADSL modem I brought with me from australia, and its running as a router now using one of my lan ports as the wan port. As such it goes through the same firewall procedures as if the RJ11 was the wan port. Only difference is that the RJ11 is first demodulated.

To the original poster, as I said, if you have a cablecom 25 plan or higher, to solve your particular problem the cheapest way, get a switch - they cost about 10 - 15 bucks for a simple small one (see link in my last post)

actually, i'm after a new router. i have one of these fabled ADSL routers where the software is not capable of correctly routing from the LAN side.

i got around this by disabling the NAT on the router and setting up a separate server with DHCP and instructing all computers to route through this server.

while this set up is a bit unnecessarily complicated, it has been rock solid and has worked for 3 years without maintenance.

but now i want to take the extra computer out of the equation and replace the wireless router with one that can take an IP address from a LAN broadband modem and act as a DHCP host and issue IP addresses over WIFI and ethernet.

i only need 100mbit lan and 802.11g wifi. the main requirement is that the router should be 100% reliable and i can plug it in and forget about it for several years.

in the past, i've experienced wifi routers which hang and need periodic resetting. can anyone recommend a rock stable one that they have been able to use and have had in place for several years without need to reset or administration?

Just got a NetGear DGN2200 from Steg to replace my old Alcatel, as I had problems with some websites on my Ubuntu computers, but not Windoze or Macs, strangely, but my server is Ubuntu, as well as my new netbook (ditched the MeeGo), so I had to solve the problem, and it did.
