Yes, but you should also put the modem on a different subnet from the router. For example, if the router is 192.168.1.1 then put the modem at something like 192.168.0.10. That way you should be able to configure the router to "see" the modem setup page.

After you finish configuring the modem in bridge mode, then put the router back in the loop and run the configuration for the router. I'm assuming that the configuration software will let you setup the router to do the PPPoE stuff?

I don't have a "Billion", I've got a Huawei, so I won't be of much help there.

Billion BIPAC 5200G R4.

Well, having run the setup software again, on my iMac, the iMac is happily online using the new SSID. When I try to connect this MBA to it, it says the password is wrong, which it clearly is not, as the iMac is using it??

I can get on, as now, using the Guest Access??

Well, the original modem router AND the new Visco are both running DHCP.

Which one do I turn off?

Are both the iMac and MBA connecting via WiFi?

Well, the iMac is on the new SSID. No problem.

The MBA was on the guest SSID of the new SSID, BUT, that guest access now no longer works, since I went out to eat.

The MBA cannot get on the new (let's call it "main") SSID. As mentioned, the password is refused, even though it is correct.

Your Caps Lock key isn't down on the MacBook Air, is it? Sorry to ask, but I think that's the most common reason why 'correct' passwords are refused.

How many characters in the password?

Capslock not on.

10 characters.

??

Can you turn on verbose logging on the router?

Can you try to copy and paste the password?

Can your iPad connect?

I have enabled the log. It doesn't specify verbose, or otherwise. The log display offers in, out, security and dhcp. Which one?

The pwd is copied and pasted.

Pads and phones and all other devises cannot connect to Tiger (main SSID). MBA was on Tiger Guset, but that will not connect now, even though it remains enabled. MBA now on the old Billion SSID.

So, both routers are transmitting SSID and doing DHCP.. Surely, one of them must have dhcp turned off, yes?

Tx.

When you talk about two routers are you talking about the Billion modem/router and your new LinkSys router? If so, the Billion should be in bridged mode with everything else off. DHCP off, etc.

Does the Billion box do WiFi? Is that where the second SSID is coming from?

Only one router should be broadcasting an SSID and only that router should be doing DHCP.

The Billion is still there because it is the modem.

So, for the Billion box, turn from PPoE to Bridge.
Disable DHCP.

ANything else?

Tx.

That should do it.

Now posting from iPad tethered to iPhone...

OK, now all devices can get on Tiger that emanates from the new Cisco.

However, there is no Internet connection and I now have no way of getting into the Billion settings to make any further changes. I have tried an Ethernet cable from the Billion box into the back of the iMac, but no dice.

The guy who sold me the Cisco actually said to leave dhcp on in the billion and off in the Cisco???

Did you change the IP address on the Billion to be in a different subnet from the rest of your LAN? You should be able to connect the Billion via an Ethernet cable and access the web setup using whatever IP address you gave to the modem.

I've attached screenshots of my modem setup. As you can see, bridged mode, no DHCP.

I don't get the advice of having the Billion do the DHCP. Why buy a robust router if you're going to leave the routing to the modem?

So how can I get back into the Billion now?

Turn off the LinkSys.

Connect the Billion with an Erhernet cable.

Type the IP address of the Billion into web browser.

You should be connected.

Did that. Entered 192.168.1.1 and nothing. "Server isn't responding".

In network preferences, the ethernet link is showing "self-assigned IP".

Restarted the Billion. No change.
