Good evening zeroburn
OK I am sorry on you not being able to set it as a AP it must be a limitation of the Broadcom chipset and then DD doesn't enable it then. I know with a lot of Atheros-based chip that this is a option.
Who is your ISP? and do you have DSL, Cable, T1 etc and do you have a static IP or DHCP coming in. The link you provided is V24 that supports wireless bridging!
#1... your first (primary wireless router) how is that one set up and what is the IP set up: The router is set as a "router" with DHCP etc and if you are static what addressing are you using from your ISP? and for in-house you are (192.168.1.100 and subnet 255.255.255.0 and gateway 192.168.1.1 etc)
#2... What is the make and model of your 1st primary router. (i.e linksys WRT54G etc)
#3... What is the modem from your ISP is that a modem & router or is it just a modem.
#4... Is the primary router running DD-wrt and is so is it the version?
These are the instructions for your chipset you have. The broadcom chipset.
I did find this info just in-case you did not ever see it from there web site and these settings are just for "wireless NOT wired"
Broadcom
[edit] Instructions
A very simple step-by-step description to connect a Router running selected DD-WRTV24 firmware in Repeater Bridge Mode. (This will work for almost everything, but do check notes on individual routers below clock).
If you are using a G router, use 12548 builds to create a wireless bridge. DO NOT USE SP1 OR THE MAY 24 08 BUILD.
This mode is NOT for WIRED connections between two routers! It is a wireless connection only.
To enable bridge mode between two routers, the primary router must be in AP mode (default) with DHCP Server enabled. The secondary router running DD-WRT v24 will be configured as the Repeater Bridge.
Restore Factory Defaults on Secondary (DD-WRT) Router
Do a proper HARD 30-30-30 Reset on the router.
Set your computer to a static IP of 192.168.1.9 if you know how to set static addresses. Otherwise leave your computer's network adaptor(s) programmed with the factory default setting of DHCP and the router will assign a valid address to your computer.
Connect your computer to the secondary router via wired LAN port or as a wireless client. The dd-wrt default wireless SSID is "dd-wrt"
Open the address
http://192.168.1.1 in your web browser. Newer versions of DD-WRT will require you to set a password before you can continue.
Open the Wireless -> Basic Settings tab
Physical Interface Section
Wireless Mode : Repeater Bridge
Wireless Network Mode : Must Match Primary Router
Wireless Network Name(SSID) : Must Match Primary Router exactly including exact case- Make sure you spell this correctly
Wireless Channel : Must Match Primary Router (This will disappear once you put it in RB mode, and isn't needed)
Wireless SSID Broadcast : Enable
Network Configuration : Bridged
Save
Virtual Interfaces Section
Add
Wireless Network Name(SSID) : Different from Primary Router
[NOTE] - You CAN try using the same SSID but it usually will not work properly. Many have had random disconnects and/or no connection if the SSID's are the same.
Wireless SSID Broadcast : Enable
AP Isolation : Disable
Network Configuration : Bridged
Save
Open the Wireless -> Wireless Security tab
Physical Interface Section
Security Mode : Must Match Primary Router and DD-wrt only works reliably with WEP or WPA2-AES
WPA Algorithms : Must Match Primary Router
WPA Shared Key : Must Match Primary Router
Key Renewal Interval (in seconds) : Leave default
Virtual Interfaces Section (note if you don't see this section your firmware should be atleast v24-sp2)
Security Mode : Must Match Physical Interface
WPA Algorithms : Must Match Physical Interface
WPA Shared Key : Must Match Physical Interface
Key Renewal Interval (in seconds) : Leave default
Save
Open the Setup -> Basic Setup tab
Connection Type will be: Disabled
Set STP for Disabled (Enabled sometimes can cause connection problems) redhawk
IP Address : 192.168.1.2 (Assuming Primary Router IP is 192.168.1.1)
Mask : 255.255.255.0
Gateway: 192.168.1.1 (again assuming Primary Router IP is 192.168.1.1)
DHCP Server: Disable
Local DNS: 192.168.1.1 (if IP of Primary Router is 192.168.1.1)
Assign WAN Port to Switch : Optionally enable this to use the WAN port as another LAN port.
Save
Log back into the router at it's new IP address of
http://192.168.1.2
Open Setup -> Advanced Routing tab
Set Operating mode to "Router"
Save
Open Services
Disable Dnsmasq
Save
Open the Security -> Firewall tab
Uncheck all boxes...except Filter Multicast
Disable SPI firewall
APPLY Settings
Reboot the router.
Once you have it working, go to the wireless security tab, and set the same type of security AND key for both the primary and the repeater ssids and hit apply. Avoid WPA2 Personal MIXED, as it will likely kill communication between the routers (see Security section below for more on this). WPA2 Personal is fine.
SET YOUR COMPUTER BACK TO AUTO IP AND AUTO DNS.
You should now be able to connect wired clients and wireless clients to the newly configured Secondary router . They will receive IP Addresses from the Primary Router and will be able to use the Internet connection supplied by the Primary Router.
Also take note of the fact that all repeaters, including this Repeater Bridge mode, will sacrifice half of the bandwidth available from the primary router for clients wirelessly connected to the repeater. This is a result of the repeater taking turns talking to not just one partner, but to two, and having to relay the traffic between them. As long as your internet bandwidth requirements are within this halved bandwidth amount there will be little or no reduction in "speed".
[edit] Troubleshooting
Encryption type and key must be the same on both the primary and secondary router. The first thing to do when running into problems is to remove all encryption and see if the routers can connect. This is the single most common reason that bridged routers don't work
[edit] Wireless Clients cannot connect to Repeater
Disable security and try again. Delete and re-create your profile on the wireless computer. Check to make sure you have set security properly and that the key you used matches the key in the primary router. If one security type doesn't work try another on all routers. eg. try WEP or WPA2-AES [Mera Pakistan]
[edit] NAT
Open the Set-up -> Advanced Routing tab and change the mode to "router" instead of "gateway".
[edit] Wireless Clients have no Internet
Make sure you have a gateway specified in the repeater bridge router, and that the address there is the primary router.
[edit] No packets making it accross the bridge - "Auto" channel setting
Pulling your hair out? Sporadic documentation got you down? Are you using the "auto" setting under Wireless -> Basic Settings - Wireless Channel? Try setting this to a fixed channel. Two days worth of battling with v24-sp2 on a d-link 615 d, with nary a mention of this setting in any walkthroughs. If this still dosn't fix it, try setting up the bridge with security disabled, then re-enable it once its working.Fonz 05:01, 9 September 2010 (CEST)
This is actually part of Step 5. Don't miss any parts of each step
[edit] Issues with DIR-615 D4
The forums are full of people having issues with getting this to work on the DIR-615 HW rev: D4. I was able to get this working very easily using the latest brainslayer firmware. Less steps are needed for it also. See:
http://www.dd-wrt.com/phpBB2/viewtopic.php?t=153372[edit] Linksys
(Likely the same for al broadcom)
After this make sure your new subnet/ip address settings are working well on your router. If you try to do the wireless bridging first without making sure that your router isn't on the same ip address as the primary and is on the same subnet your router may become unresponsive. A 30-30-30 reset will fix this problem.
Finally, once and ONLY AFTER you are connected to your host AP, as the final step you will want to go to Setup > Advanced routing tab and change the setting from Gateway to Router. Then enable dynamic routing for both Lan & Wlan and apply your settings.
The other steps and procedures listed above for broadcom should work perfectly. I advise using a wired connection as it verifies the connection to the host AP best, then you can test wireless capability. Mine worked beautifully with WPA2 encryption and SSID's being the same.
Make sure that you click save, not apply between each step, as when you click apply, you will activate all changes, which may make accessing the router difficult.
I really hope this helps I know how frustrating it can be, please let us know how you make out, Mike
