Most modern “modems”, whether DSL or cable, are a combo modem/router, and a few details
you’re provided do confirm that’s what you have. From what you’re saying you were using some
of its router functions previously with the DI-624 (for example, NAT), which makes me wonder what you were using
the DI-624 to do; the two possibilities are to provide extra Ethernet ports (i.e., acting as a small switch) and
to be a wireless access point.
So I’ll presume that the “modem" should continue to be your router (configured
with PPPoE username and password to get your Internet connection, and providing NAT and DHCP), and
the WRT150N is just a switch / wireless access point. Most Linksys firmware is pretty similar, so
configure the WRT150N as follows (assuming LAN subnet is 192.168.2.x and modem/router is
192.168.2.1, adjust as necessary):
* Setup / Basic Setup
Internet Setup [basically irrelevant, you won't be using the WAN side]
- Internet Connection Type: Static IP
- Internet IP Address: 192.168.3.2
- Subnet Mask: 255.255.255.0
- Default Gateway: 192.168.3.1
Network Setup
- Router Address: 192.168.2.2
- Subnet Mask: 255.255.255.0
- DHCP Server: Disabled
- Time Settings: optional, normally irrelevant
* Wireless / Basic Wireless Settings [as present in the WRT150N]
- Network Mode: Mixed
- SSID: your wireless network name
- SSID Broadcast: your choice, normally Enabled
* Wireless / Wireless Security
- Security Mode: WPA2 Personal [some older PCs don’t support WPA2, if so then
just WPA Personal]; with AES if an available option
- Passphrase: your wireless password
You cable one of the WRT150N’s *LAN* ports (not the WAN port) to the modem, and
you have the other three available LAN ports on the WRT150N and its wireless as your LAN.
If you wonder why you're connecting to the LAN side, not the WAN side: WAN->LAN does
NAT, which is already done in your modem, you don't want/need a second level of NAT.
If I’ve misunderstood anything, let me know and I can revise my advice. Also,
I’m curious about the make/model of your DSL modem.

P.S. I have DSL at home, with two separate routers of my own. Most combo
modem/router devices can operate in one or both (simultaneously) of two modes:
- router, providing NAT, DHCP, etc. as you seem to be doing
- bridge, providing a direct PPPoE “interface” for your router to connect via
PPPoE
My DSL modem (Bell [Canada] Internet, previously a 2Wire 2701, now upgraded to a
Sagemcom 2864 for 15/10Mb service) operates in both/hybrid mode, but I ignore the
router side and just connect multiple PPPoE-configured routers to it (Bell's service
will deliver multiple PPPoE connections/IP addresses using the same username/password,
I’ve had up to five for testing routers but only use two now - one is my
personal home network, the other my home office network).

Subject: [OM] need router help
My faithful old D-Link 624 which I saved from an ignominious death in the free
box at a community garage sale many, many years ago has finally passed
(respectful silence)
So this upstart Linksys WRT150N which I had in reserve has now stepped up to
starting position. Now this router is no spring chicken either but given my
situation in the backwoods it should be able to keep up with our needs. I
could use some help setting it up right.
First off I changed the IP address which defaulted to the same one as the
modem. Then set up the internet connection. So far so good. But now this eager
beaver new router thinks it should be handing out the NAT assignments a job
which the modem was doing just fine (I assume??) without any help from the
DI624 (which wasn't the sharpest knife in the drawer). That kinda screws up my
network.
I tried disabling NAT in the modem setup and setting up the PPPoE connection
and logon through the router but obviously I haven't a clue. Reverted back to
Auto DHCP. So what do I do? I really need my printer back on the network.
