Dlink modem+router AND wi-fi router configuration question

Recommended Posts


I have two Dlink products:

1) ADSL modem + 4-port switch, Dlink DSL-2540B

2) wireless router + 4-port switch, Dlink WBR-2310

I am using AT&T DSL service (PPPoE). I connect the DSL phone line to Dlink DSL-2540B and then connect the "1" port of Dlink DSL-2540B to the Dlink WBR-2310 "WAN" port.

I will use a laptop with wireless connection (801.11b) for BT.

I want to configure my 2 Dlink product to route BT correctly. Could someone show me how to do that? Do I simply use "Virtual Servers Setup" in Dlink DSL-2540B ( Do I have to setup anything for Dlink WBR-2310 (

The DSL-2540B is also a router, and the WBR-2310 is an unneeded second router. To uncomplicate things, we will bypass the router part of the WBR-2310 but still let you use its ports and its wireless function.

1. Enter the configuration pages to the WBR-2310

2. Turn off the UPnP function

3. Disable the System Logging functions

4. Turn off the DHCP server function

5. Unplug the cable going into the WAN port of the WBR-2310 and plug it into one of the WBR-2310 LAN ports (so that both devices are now connected via LAN ports).

6. Reboot your systems so that they get appropriate DHCP addresses assigned from your DSL-2540B. If you are using Static Addressing, all devices on your network should use as the gateway and as the subnet mask.

By taking those steps, you have made the DSL-2540B your network's only router. The WBR-2310 is now a Wireless Access Point connected to a 4-port switch (one of which you are using). Anything connected to the WBR-2310 by LAN port or by wireless will still be managed by the DHCP and router rules of the DSL-2540B. Leave the WAN port empty on the WBR-2310.

Thanks for the reply!

I also have a Buffalo WHR-G54S router. Is there a way to use it as a access point to strengthen the 801.11b signal?

I have my Dlink DSL-2540B and Dlink WBR-2310 on the first floor, and I want to put my Buffalo WHR-G54S on the 2nd floor. The laptop is also on the 2nd floor. I want to use Buffalo WHR-G54S as a switch and as a access point. I will connect my desktop (ethernet) and my laptop (801.11b) to my Buffalo WHR-G54S on the 2nd floor.

I can't say that I'm familiar with that router, however the steps I recommended for the WBR-2310 generally apply to any wireless router. The possible problem, in your case, is that you need that LAN-port to LAN-port connection from the WHR-G54S on the second floor back to the DSL-2540B modem on the first floor.

The WHR-G54S probably does not support a "wireless repeater" mode on its own, but if it does, that is another configuration option. If it does not, you may be able to get "alternative" firmware that does support that mode. A good place to ask questions about this is the Buffalo forum on DSLReports.com.

Still, repeaters are troublesome and they cut your wireless bandwidth in half. If I had a poor signal on the second floor, I would take a different approach.

1. Reorient the antenna of the WBR-2310 so it is at a slant that favors the upper floors of the house. If the antenna is pointing straight up, then the TX/RX pattern is parallel with the first floor. But if the antenna is pointing towards the walls, then the pattern is parallel to the walls and the signal will be better above and below. The pattern to those rubber-ducky antennas is shaped like a doughnut and the signal extends outward from the sides of the antenna. Keeping all this in mind, try moving that antenna so that it "shines" more toward the part of the house that has the poor signal.

2. Replace the removable antenna on the WBR-2310 with an improved one, such as one from THIS page. The various antennas on that page will let you "shape" your wireless TX/RX area, and you can set the antenna to direct more signal toward the upper or outer reaches of your house.

3. Try replacing the WBR-2310 with the WHR-G54S (same configuration suggested above, no DHCP server, no UPnP, no logging, LAN-to-LAN). The WHR-G54S may (or might not) have a better antenna than the WBR-2310.

That should not be a problem because both 192.168.101 and 192.168.101 will be used on my laptop only. So, only one IP will be used at a time, and only port 55556 will be forward at a time.

Right now I have this situation:

1) 192.168.101 is for my laptop ethernet connection. BT is fine. 55556 is opened.

2) 192.168.102 is for my laptop 801.11b connection. BT is blocked.

Please advise.


Sorry, I just changed the port for 192.168.102 to 55557. It is ok now.
