Can't get router to work

...or rather it seems my modem doesn't work with my router. I have a 2011 Mac mini and use a Motorola MSTATEA 2210-02-1002 DSL modem. Earthlink is my service provider.

For security reasons I want to put my old Linksys Etherfast Cable/DSL router between the Mac and the modem. On the router I get all green lights for "Ethernet" and "Internet." On the modem I get green lights for Ethernet, DSL and Internet, but I get a slowly and steadily blinking green "Activity" light, and I can't get a connection.

I do not get an internet connection, and after a while the Mac opens Network Settings:

- ethernet ok
- network settings ok
- ISP fail
- internet fail
- server fail

I am told to restart "the device." Doesn't say which one (computer, modem router). I tried all. I also reset the router with the little reset button on its back. It's a no-go. Please advise!

What is the exact Model of your Router?

hello doc,

router is a linksys befrsr41ha, that was the exact url I told moribundman to follow!

I'm curious about something. is the linksys befsr41 router any different to setup than an apple airport router? I know the befsr41 is wired and the airport is wireless. I don't mean that. I mean the "bridged mode" thing. if I understand correctly, when you follow the instructions at the above link, the 2210 modem will be put in "bridged mode" and the befsr41 router will handle the pppoe.

a while ago you and wayjac showed moribundman and me how to connect a 2210 modem to a mac via an airport router:
»[General] PPPoE or DHCP with Earthlink (Mac OS X 10.4)?
it seemed that in that case the 2210 modem handles the pppoe.

are the two setups different or are am I overlooking something?

Thanks

The instructions at the link you posted are for a 2210-02-1006
The gui of the 2210-02-1006 and 2210-02-1002 look different

Yes the two setups are different
One setup has the modem bridged with a router doing the pppoe
The other setup has the modem doing the pppoe

I'm curious, what is that dictates who will do the pppoe? I once had a befsr41 and I remember that, unlike the befsr41 setup in this case, it was the dsl modem that handled the pppoe.

You should set the Modem to Bridge Mode/Bridged Ethernet Mode and then setup PPPoE in your Linksys befrsr41.

Otherwise you are cascading Routers and performing NAT multiple times (Double-NAT in your case) which isn't the optimal setup.

You will decide which device will do the pppoe......

The dsl modem can be configured to do the pppoe or the dsl modem can be configured for bridge mode, when the modem is bridged a router or computer must do the pppoe

the cascading and double NAT will happen because the 2200 modem is also a router doc?

and since the 2200 modem is a router too, will it do NAT if you connect the 2200 to the computer alone without a router, thus giving you the security benefits of NAT?

are there any benefits to doing the pppoe on the modem or the router?

btw, do you know if the SpeedStream 4100 modem is a router too?

Yes the SS4100 is a router for one device only
