| Questions about router config after ordering dsl service Finally ditched my cable internet and now have DSL service.
My previous setup with cable was a Scientific Atlanta DPC2100 modem in front of WR850G (DD-WRT) wireless router. This allowed internet to be shared with two other pcs in the home.
My new DSL setup will keep the same router in place so that internet can continue to be shared. The DSL modem is a 2210-02-1002.
Do I reconfigure the DSL for Bridged mode? Or select PPP on computer. I am getting conflicting advice on this and I guess it determines which settings I change on the router. My previous understanding was change DSL modem to Bridged then set my router to PPPoe. I just want to get as close to the configuration I had with the cable setup as, admittedly, it was always a seeming automatic process.
Also, will my two other pcs and PS3 console still be able to detect my network?
Thanks. |

ACK!!! For some reason I'm no longer able to log in to the web-based gui for my router 192.168.1.1 to make the recommended changes. I was just able to earlier today and have done nothing that would brick it.
The only way I currently have internet is the DSL modem connected directly to my pc. The router is out of the equation. When I hook the router up between the modem and pc, there's no internet but was able to log into the router. Now I can't - but I don't know what has changed.
Sheesh! I'm about to have a siezure from this.
Any help is appreciated. |

Hmmm. I've used the "PPP on the modem" setting with the configuration set to share the public IP address. However, according to the logs, sometimes the modem assigns private IP address 192.168.1.64 to the router WAN port before getting the public IP address to share. Some routers don't like to see the same subnet on both sides of the router (i.e., 192.168.1.64 on the WAN port when the LAN is configured to 192.168.1.1/24, as your Linksys router).
One way to mitigate that would be to disconnect the modem from the router, and reset the router (to clear whatever error condition the router might have entered). Then, if that lets you back into the router, change the router LAN IP address to anything other than 192.168.0.1/24 (mask 255.255.255.0), or 192.168.1.1/24 (mask 255.255.255.0).
The other way (you should still reset the router) would be to put the modem into "bridge" mode, and put the PPPoE session on the router (this would actually most closely simulate your old cable connection; cable modems act as dumb bridges, as would your Motorola 2210. Just be aware that the PPP session is, effectively, a tunnel, which will prevent you from having TCP/IP access to the modem through the router.

Change DSL location | 
WAN configuration | 
LAN IP configuration | 
DHCP configuration |
1. With the router disconnected from the modem connected my laptop to the router and changed its LAN IP to 192.168.10.1 for example. I also had to configure the router DHCP server for the same address range, ie. 192.168.10.101 and up in my example. You need to do this because the 2210 operates in the 192.168.1.X range. That can not be changed.
2. Connected the laptop directly to the modem and selected the PPP on the computer setting. Make sure you save it. You address the modem using 192.168.1.254 by the way.
3. Connected the modem to the routers WAN port. The router should be configured to get a DHCP assigned IP address. Depending on your router you may need to change the router MTU to 1492 if it defaults to 1500 (cable).
If you set this up right your clients, wired or wireless, will get their DHCP assigned IP addresses from the router and everybody will be able to access the internet via the DSL connection.
If you need to access the modem from your computer to change it back to a non-bridge mode make sure the computer IP is set to 192.168.1.10 for example and connect it directly to the modem. Address the modem as normal, ie. at 192.168.1.254...
The screen shots are from my 2210 and a ZyXEL router and are to be used as examples only...
There is also this as a reference...

| Hey, thanks for this! Nice explanation.
I was finally able to log into my router successfully. Had to use a combination of hard reset the router, unplug then power back on, change tcp/ip settings in windows to match the router ip. Then I was in.
I will follow your instructions when I get home later today and report back.
Thanks again. |

SUCCESS!!
Hey Sooneral, thanks for those instructions! That made the difference. Everyone else had been telling me to set my modem to Bridged Mode. But the more I looked at the PPP on computer option, the more it made more sense than the other two options.
By the way, I also had to fill in the DNS1 and DNS2 fields with data taken from the modem. Did you have to do that? Or I wonder if it makes a difference.
Anyway, a big thanks to you!! |

kudos:5 | No I did not manually fill in the DNS fields but it can't really hurt any.
Glad it worked for you. Merry Christmas and Happy New Year...
