For SMC7904WBRA :: How to use Cable Modem on ADSL router/modem

Hello, I have a SMC7904WBRA2 ADSL Modem/Router combo. Recently I changed ISPs, and now I use a cable modem. I'd like to know how do I set the combo to work as a router only, and how I configure it. If I just plug my new cable modem on the router, only one of the computers get internet access, not the others, and I don't know why. The Cable Modem is a Motorola SBV5120.

Looks like your device does not support playing router for cable internet. Would recommend you get an actual router, or alternately if you have a computer with two network adaptors you could plug one into cable modem, plug other in to LAN side of router, then configure turn Windows Internet Connection service, will need to disable the DHCP service on the router. I highly recommend you get a real cable/dsl router to do this tho. Linksys 54g series has been one of my favorites. Router homepage on SMC site.

Using WRTS4GS2 Cisco Router and could not access the internet. Remobed router and had instant access to the internet.

Contact your ISP. Some ISPs limit the number of computers that can simultaneously connect to your cable-modem. If you change computers, you have to tell your ISP.

Or, power-off your cable-modem, to "reset" it.
Connect the Cisco Router to the cable-modem.
Power-on your cable-modem.
Power-on your router.
Connect your computer to your router, and see if you get Internet access.

I recently moved from Cable ISP to DSL ISP service. For the DSL service, I was asked to configure my Router to use PPPoE with Dynamic IP addressing. I also provided the router with my username and password...

The reason you have no internet is because the router is specifically for cable. your description contains errors what i think you mean is that you have gone from cable dsl to an adsl, correct me if i am wrong. Basically your modem connected to your router via an ethernet cable and then the router fed the wireless signal to your wireless devices or via ethernet through the 4 ports in the back. With adsl you have a feed from your phone line to an adsl modem so the only way for you to get the dsl router working is to have two ethernet leads connecting to your pc, one from the modem to the pc and one from the pc to the router. You would also need to setup internet sharing on the pc thats connected to both devices.

Either do it that way or buy an adsl router

Sitecom WL-342 Wireless Router won't access internet.


Make sure there is a network cable going from your ADSL modem into the WAN connection of the router.

If the ADSL modem is wireless, then it is also a router in whihc case you will want to bypass the WL-342 all together.

Switch off modem on belkin 54g

I'm guessing DSL to CABLE switch? Most will tell you no but it can be done. ISPs commonly use dual modem/router type devices in order to charge some sort of fee every month to the consumer.

Essentially what you're going to be doing is running a line from your wall to the modem. Now instead of running a line directly from the modem to the PC what you're going to be doing is I believe plugging it in to the 4th position on the back of the combo device. 1st you may have to reconfigure the device for your new ISPs information ie. DNS SUFFIX, IP ADDRESS, etc. Don't quote me on this but I believe to do that you'll have to connect the ethernet line directly from the PC to the combo device via port 1 on the device. That will enable you to configure the device as you would any other router. 

It's all a bit of a pain in the rear but it can be done. I've noticed forums around the net describing the process in further detail but without model specific information the best I can say is yes someone somewhere would know how to do it so don't let anyone especially your ISP say that it can't be done.

Best of luck!

Help me please

I think Not.
There are ADSL wireless routers however.
I guess your purpose is to make your ADSL modem available wirelessly, you can connect the
modem via lan line to the wireless and use that as a router.

MAC address cloning

Hi killer - MAC (Media Access Control) cloning is used to clone your MAC address.
Some ISPs (most notably MediaOne) use your NIC's MAC address to authenticate your service. When you change the computer that you have connected to your cable modem service, you usually have to call up Tech Support and give them the MAC address of the NIC in the new machine. Since hardware routers have the equivalent of a NIC on their WAN port in order to connect to your cable modem, you would have to do the same thing if you're installing a router.
Recently, however, some ISPs have started to recognize the MAC addresses of popular routers and disconnect service if a router is detected. Fortunately, many router manufacturers are including the capability to either set the router WAN port MAC address to anything you want, or copy it from a computer connected to the router LAN side. You can check the Router comparison chart under "Mac addr. clone" to see which routers support this feature. Then consult the router's documentation for directions on using the feature.
So basically, it's used to fool ISPs into thinking there isn't a router. If the router has the same MAC address as either your NIC card or your modem the ISP won't detect and service won't be interrupted. Most ISPs don't do this so iy's rarely needed.
If this answers your question PLEASE rate this as fixed. If you need more help just add a comment and I'll be happy to assist you further. Thanks.

Problem with Local area connection

In general the Wan port of the router gets connected to the ADSL modem where the computer used to connect and the computer connects to the switch portion of the router which often has 4 ports. The router has configuration options that must be set to comply with your internet service providers (ISPs) requirements. These can often be found on his support web site. If you can provide the link to the website I can assist with the search. Otherwise I will need the name of the ISP. If this ISP is cable related like Road Runner I will need the associated cable provider. I will also may need to know the country, city and state in which you are located as some ISPs have geographic differences in equipment. Depending on what that information determines I may also need to know the Manufacturer and Model of the DSL Modem -- probably the box your computer plugs into when it is working. It would also be helpful to know if you got the router used or new. Used routers may have been configured by their previous owner and require additional changes to new routers with factory default settings.

Lastly as a wild guess. There are some ISPs that extract address information (MAC Address) from the attached network card into the units they send you to attach to the phone line or cable. Should you happen to be with such a company they often state turn on the modem before the router so it recognizes the change. You may want to try turning off the modem attaching the router without power then turning on the modem wait a minute and power on the router -- if your ISP requires default settings for your router and it was new this may work. As far as the alarm for unplugged cables -- do the cables have the clip portion on the ends and are they securely established in the ports. Are the contact points on the cables free of dust and dirt? Especially if the router is used have you tried a different port for the computer side connection? In case of the computer end have you tried multiple computers -- possibly a friend's if you do not have more than one.

There is a strong likelyhood this simple solution will not work. All of the above information may lead to the determination that we must enter a static IP address into the router, maybe we need to provide for PPPoE login for the router, maybe we need to configure the switch to allow the router to perform the PPPoE login, and several other such items. This is probably not a one reply solution.
