DD-WRT Help!

[galperi1]

I've seen a few posts in here about DD-WRT so I figured I'l post to see if I can get some help.

I currently have a Netgear WNDR3300 which I just flashed using the instrutions on dd-wrt.com and successfully got it up and running with the new firmware. However, for some reason I cannot connect to the internet and can't figure out why.

Anyone have any ideas of what I need to do to fix it?

Check to see if you have a WAN IP address.

I do have a WAN IP according the system info page

I do not know what the Default IP of the Router is.

DD-WRT set it own default make sure that your Network devices' IPs are configured with the current subnet of the Router.

Including software Firewalls Zones,. or what ever else might block or provide a new IPs.

If you're using static IPs make sure you're in the right range. If dhcp, make sure you're obtaining the correct info.

If you have a firewall or somesuch software, make sure it isn't blocking things in this possibly new network range.

I am not using Static IP's. It is set up via DHCP.

How do I see that it is obtaining the right info in that case?

Can you access the Router's Menu from the Computer while using the Browser?

Yup, I can get in to the DD-WRT menus to change all of the settings.

What type of Internet connection you have, and how the authentication (Id and pw) is done?

I currently have a DSL connection through ATT. There is a Motorola DSL Modem connected to the Netgear wireless router.

I believe the DSL Modem is set up with PPPOE where I needed my ATT user ID and password but before I flashed the WNDR3300 with DD-WRT the router was using DHCP for all of my networked devices.

Let me know if that info helps in troubleshooting.

Hmr... Sounds lilke your Modem is a combo Modem Router.

If it is so you one solution would be to use the Netgear like this,

I have that router and would not use it with DDWRT. The reason is the DSL modem part is not supported. Without that code there is no way for the modem to allow the DHCP to work separate from the modem part.

I found the DDWRT firmware was trying to work as a dhcp router but the routers chipset is slightly different in that it expects the control of the input to the switch to be controlled by the original firmware. If it doesn't receive those bits in the config when it initializes , it stays looking for a dsl connection.

I spent a few hours going over it with a serial console and it was pretty clear what was taking place. It could be fixed but I decided there wasn't enough benefit over the default firmware to bother.

Should add that the router model I have is actually the DGND3300 but the internals are the same for all that series of models.

Thanks for all the help guys! I actually did get it to work. I set the DSL modem to bridge instead of PPPOE and set the user/pw up in the router and that did the trick.
