help with setting up router as access point

August 27, 2009 at 12:09:31
Specs: Windows Vista, C2D, 2GB
I have two wireless routers, an SMC and a Siemens, in two different rooms. The Siemens router must be DHCP-enabled because it's also the ADSL modem, so the SMC has its DHCP turned off. The Siemens is too far away and signal too weak for wireless access in the area around the SMC router, so I'd like to use the SMC router's wireless capability (using it as an access point)

The problem is, after I turn on the SMC's wireless function, devices can't get wi-fi access even though they can detect the signal just fine. Wi-fi doesn't work through the SMC router even if I turn off any encryption. Wireless devices don't seem to be getting an IP properly, even though wired devices can get one without issue.

Is anyone familiar with such a setup -- what am I missing, or is something wrong?

To use the SMC as an AP you will have to have it plugged in to a LAN port on the Siemens router.

You will go from LAN port on the SMC to LAN port on the Siemens.

You will want to assign an IP on the LAN side of the SMC that is outside the DHCP scope (on the Siemens) but within the same subnet. The subnet mask needs to be the same and the gateway IP should point at the Siemens router. Then you'll want to setup the wireless. Use the exact same SSID on the SMC that you're using on the Siemens but make sure you put it on a different channel to avoid overlap and interference. So have one set on channel 1 and the other on 11.

The following is an example of network settings to give you an idea what I'm talking about:

Seimens Router LAN settings:

DHCP scope: to

SMC router LAN settings:
Default Gateway:

You will want DHCP disabled on the SMC as once everything is setup and working properly clients connecting to it will get their DHCP from the Siemens router's DHCP.

thanks Curt. My problem may be SMC's default gateway setting. It's not under the LAN settings which only contains
1) "IP Address" (set to an IP outside Siemen's DHCP range),
2) "IP Subnet Mask:" (which can't be changed), and
3) "DHCP Server: enabled/disabled" (set to disabled).

Could it be under the "WAN" section? Here there are some subsections that might be related:
1) "Dynamic IP (Obtains an IP address automatically from your service provider)". Contains "Host Name" and "MAC Address".
2) "Static IP (Your service provider provides a static IP address to access Internet services)". Contains "IP address assigned by your Service Provider", "Subnet Mask", "Service Provider Gateway Address". What IP am I supposed to put for "IP address assigned by your Service Provider"?

...or could this simply be a shortcoming of the SMC router? It's a 2804WBR which was made around five years ago.
