using adsl modem router with ethernet switch

Specs: Macintosh
Hi there

I have an ethernet port at work and have connected a Netgear 5 port switch in order to increase the number of ports in my office.

I also have a Linksys WAG354G v2 adsl modem/router combo which I would like to add to the network so that I can broadcast a wireless signal (for iphone, and visitors etc).

In effect I'd like to use the Linksys as a wireless router only (ie 'disable' the adsl modem part of it).

I simply plugged an ethernet cable from the Linksys router (after a hard reset) into one of the ports on the Netgear switch and now have wireless access through the default wifi ssid.

However, I am not able to access the Linksys setup page (at http://192.168.1.1) in order to set up wireless security. My browser times out. This occurs whether I connect via ethernet or wireless to the Linksys router.

Can anyone help me with some networking 101? I should be able to do this, but what am I missing?

Thanks in advance.
Simon

Is there another router, network printer or computer, that might have already this ip address 192.168.1.1?
In that case, you'll get an ip address conflict and have to disconnect the Linksys WAG354G v2 from your network temporarily and connect a computer directly by wire. Then change the ip address of the Linksys Router to e.g. 192.168.1.2, save settings, connect everything as it was and connect to the Linksys Routers Web Interface.

P.S. At first, check, whether the ip address, you are going to assign to the Linksys Router, in not already in use.

Thanks for the response.

Excuse my lack of networking experience here but:

a) how do I check what IP addresses are being used? (I'd normally do that by looking at the router interface via a browser - but can't get at this). I'm running OS X.

b) do you mean to connect a computer to the Linksys router by wire? That is, just run an ethernet cable from my puter to the back of the router (whilst keeping the router connected to the switch).

Apologies for confusion.

Cheers.

You first have to disconnect the Linksys Router from the rest of your network, otherwise, if there is an ip address conflict, you'll never be able to get the web interface of the Linksys Router.
Then plug in the lan cable of your computer directly into the Linksys Router.
Your computer should be configured, to get an ip address automatically.

So what do we have now?
We have the Linksys Router, connected to it's power supply and one of the LAN ports of it is connected to your computer.

Now use your favorite internet browser and try to connect to the Linksys Web Interface by typing http://192.168.1.1

You should now run a ping to 192.168.1.2 and check, whether you get a reply. If you get a reply, the ip address is already in use and you must try to ping another ip address, e.g. 192.168.1.3.
This must be done, til you have found an ip address, where you get no replay (so you get a timeout).

If you get connected to the web interface, change the ip address of the router to e.g. 192.168.1.2 (use the ip address, you figured out in the test, mentioned above).
Save the settings and connect the Linksys Router back to the network as it was. Connect your computer also back to the network as it was and try to access the Linksys Router again by http://192.168.1.x (again the ip you've configured for that Router).

Post back the result.

Thanks so much for such a clear response. I was able to (obviously) connect up, change the IP (and organise password etc for the WAP). Once I reconnected the wifi router to the network setup the new IP timed out again! So, something is not quite right, but the upshot is that I did what I needed to do.

Thanks again

Strange !!!
Maybe the router (192.168.1.2) is not in the same network range as your computer.
If you'd like to check that, simply click START / RUN type in CMD, click ok.
Type in ipconfig /all
If your ip address, listed there, is not in the range from 192.168.1.1 to 192.168.1.255, you are not able to access the routers web interface and have to pick the way I've described above.
You can also add a route to the Linksys Routers network, but that's another part.
