Using Swisscom Netopia WLAN router/modem with Cablecom modem

Hi

I have changed my internet connection from Swisscom to Cablecom.
Now I have a WLAN router/modem Netopia 3347NWG from swisscom that I would like to use with Cablecom modem (VCM02). But I can not connect the two together because on Netopia router there is a DSL connection with RJ-11 jack (phone line) while connection on Cablecom modem is ethernet with RJ-45 jack.

Any idea.
Thanks

Unfortunately you have to buy a new WLAN router that doesn't have an ADSL modem included in it. Sorry, it is just the way that they build them.

Re: Using Swisscom Netopia WLAN router/modem with Cablecom modem

Hi

Just to inform that I found a solution to the problem above.
Got it from an IT guy at the company where I work.
Connect the cablecom modem and Netopia router/modem with ethernet RJ-45 cable and then unplug the cablecom modem from power supply for about 10 min. After that plug in the power cord again and wait 2 min. Few seconds later and wireless connection works again. Unplugging the cablecom modem resets the connection ad both devices automatically synchronize when you plug in the power again.

So if anyone else change internet connection from Swisscom to Cablecom can use old wireless router/modem without any problems.

Re: Using Swisscom Netopia WLAN router/modem with Cablecom modem

actually you could plug the cable modem into the LAN socket and use it as an access point. I don't see how you can use the NAT or other features though?

Re: Using Swisscom Netopia WLAN router/modem with Cablecom modem

Hi Rockster

Actually I plug the cable modem into LAN socket on the router from the very beginning, but it did not work. And that is when I posted the question here if anyone new someway to solve this.

What I did not know is that reason for not working the first time was that I have not disconnected the cable modem from power supply, so router was not able to require new IP address form the modem. By reconnecting the modem, router automatically acquired new IP address and things worked again.

And this reconnecting is something unusual, because usually router is able to acquire IP address immediately when it is connected, without power disconnection. But with cable modem from Cablecom this does not work.

I don't know about other functions, since I only needed the wireless in my home without having any cables connected to my laptop. WEP protection is also working and that is all I need.

Re: Using Swisscom Netopia WLAN router/modem with Cablecom modem

Just switched from Swisscom to Cablecom.

I have the infamous Netopia 3347-02 router.

I cannot get it to work with Cablecom's modem; I did try what the previous poster suggested, to no avail.

Any ideas?

I'm afraid it will not work.

The Netopia router is designed to acquire an IP address (i.e. the internet connection) from the phone line, not from a LAN port. The 4 LAN ports are used to provide connectivity TO your computers.

As stated above, you need to get a proper router/access point.

Re: Using Swisscom Netopia WLAN router/modem with Cablecom modem

I know this is a really old thread, but I was searching for a solution for using the 3347 with a cable modem and ran into this thread.

To answer how to use this with the cable modem, here's why it only works sometimes.

The 3347 has its own built-in DHCP server for devices on the network, and the wireless built-in on it is a part of the network. When you connect the cable modem to the lan ports, it becomes a part of that network.

But here's the caveat--when you connect a computer to the wireless, you may get the IP address from the 3347 and not the cable modem. And then no Internet. The solution is to disable the DHCP server on the 3347. Once you do that, it should work fine.

The only other caveat to this is that the 3347 doesn't function as a router like this, just a media converter. So if you have more than one computer--wired, wireless, or a mix--only one will work at a time.

I hope this helps someone out there.

Disable DHCP and used fixed/static IP.
