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]Linksys

(Likely the same for all broadcom devices)

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.
[edit]D-Link 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 (v24-sp2). Less steps are needed for it also.
Restore Factory Defaults on Secondary (DD-WRT) Router
Do a proper HARD 30-30-30 Reset on the router.
Go to 192.168.1.1 and log in.
Go to the wireless tab.
Choose Repeater Bridge under wireless mode.
Match your SSID and channel settings exactly to the main router you will be connecting to.
Make sure bridged is selected.
Click Save.
Go to the Wireless Security tab.
Match these settings to your main router exactly.
Click Save.
Go to setup>basic setup.
Choose a local IP in the same subnet that is not being used as your main router. If your main router is 192.168.1.1 then as long as it is not in use 192.168.1.2 will work. Assuming your ip is in this range the subnet will be 255.255.255.0 and the gateway and local dns will be 192.168.1.1.
Click Save
Click Apply
The router should immediately connect and both extend the wireless range but also the LAN ports work and Internet should work

[edit]Qualcomm Atheros

[edit]Setup
Be using a build no older than r28493; if you are, then get up to date first before proceeding! Please ignore most other info on this page, it is outdated info for Broadcom units. Qualcomm Atheros units have it simple, & trying to follow most other things outside of this QCA section will result in problems.

Open the Wireless -> Basic Settings tab
Physical Interface (ath0, ath1, etc.)
Wireless Mode: Client Bridge (Routed)
Default GW Mode: Auto (DHCP). Use manual with host IP if it refuses to connect, has no internet, or unable to access either the host or bridged router from the other end
Wireless Network Mode: Match the host router
Channel Width: Match the host router, if its unknown, select wide HT40, or VHT80 if using 802.11ac.
Wireless Network Name (SSID): Match the host router exactly including capitals, make sure you spell this correctly
Network Configuration: Bridged
Click Save
Wireless Security: Match the host router, exactly including capitals & security algorithm. EX: host using WPA2 Personal AES will still work if the repeater is set to WPA2 Personal Mixed AES, for whatever reason, as it includes the algorithm in use (WPA2-AES)
Click Save

If you only have devices connected to the repeater via ethernet, click apply settings now. If you have both ethernet & wireless, or just wireless clients, continue below.

Virtual Interfaces (ath0.1, ath1.1, etc.)
Click Add
Wireless Network Mode: AP
Wireless Network Name (SSID): Same as the host router if you want a repeater, or different from the host router if you want your own separate network or for other advanced configurations
Wireless SSID Broadcast: Enable
Click Save
Wireless Security: Match the host router, exactly including capitals & security algorithm. EX: host using WPA2 Personal AES will still work if the repeater is set to WPA2 Personal Mixed AES, for whatever reason, as it includes the algorithm in use (WPA2-AES)
Click Save
Network Configuration: Bridged if you want a repeater to extend the current network of the host router, unbridged if you want your own separate network & are an advanced user
Click Apply Settings
[edit] Notes

[edit] SSIDs
Under “Wireless -> Basic Settings”, you must use only the primary router’s SSID for the physical interface to connect wireless clients and create a new SSID for the virtual interface. You will be able to tell which you are connected to as the two ssids MUST be different. (The only way to have one seamless network with the same ssid is to use WDS which almost always requires routers to support WDS AND have at least the same chipsets)
[edit]The “half bandwidth” misunderstanding
Too many people make a big deal out of the half bandwidth oversimplification of the repeater bridge setup. It’s not that big of a deal, and not that complicated. A router can only talk to one device at a time. So if the router is set up as a repeater bridge AND it has active clients, the repeater bridge router must talk to two devices- the client computer and then to the primary router. This will effectively half the bandwidth available to the client computer, but it is no different than having two computers on a single primary router. The router can only talk to one at a time, so if both are active, it will only be able to talk to one at a time, effectively cutting the available bandwidth in half. So it really is no big deal. I see people all the time who are concerned about the “half bandwidth” issue, but are not at all concerned when there are two devices on their network. It’s the same thing. And only matters at all when the device is active (transferring data to or from the wan).
[edit] Security
Dd-wrt will often not work unless BOTH the primary router and the secondary router use wpa2-aes security ONLY. Wep will also often work, but it is not secure.
Keep in mind any security settings will need to be configured including MAC filtering in order for the Secondary Router to connect to the Primary Router and also for clients connecting to the Secondary Router to gain full access to the connectivity of the Primary Router. There are some factors to consider when setting up Security for Client Bridge mode that may or may not be factors when setting up Repeater Bridge mode. I simply have not experimented with this.
[NOTE {Montrealmike}]Also when your adding WEP,WPA,WPA2 etc… between the AP and the repeater bridge you have to start with the AP first; then the repeater bridge.When you enable security on the repeater click save not apply, then click on the administration tab scroll down to the bottom and click apply settings. You will then have to power cycle the repeater twice ( unplug and plug back in twice ) in order for the repeater bridge and AP to synchronize. This has worked for four repeater bridges for me.
Edit – pmiller – I can also confirm the power cycling to sync the repeater to the AP. You can confirm that the repeater has syncronized with the AP by going to the Status>Wireless tab on the AP and viewing the MAC address of the repeater with some % signal quality value. Before doing 2 power cycles on the repeater, the MAC address would display on the AP’s Status>Wireless tab, but with 0% signal quality. After the power cycles the % quality displayed around 30%. I played around with other security settings later on the AP and found the 2 power cycles to be unnecessary after the 2 had originally sync’ed- no idea why this would work, but it did. I had some difficulty at first because I had security enabled on the AP as WPA2-Personal Mixed, which is basically WPA2-AES or WPA-TKIP simultaneously. The repeater is unable to connect with the AP in this mixed mode; rather you must choose between WPA2-AES or WPA-TKIP . I have now switched both my wireless security settings to WPA-TKIP (physical and virtual) just for simplicity, though in theory the virtual need not match the physical. Your security is as good as the weakest link. For those having trouble, I would turn off all security and turn on SSID broadcast first, then once you get a good sync turn on security on the AP first, then
Edit – crandler – WPA2 personal mixed with Linksys WAG160N as DSL uplink with original firmware and WRT160N with dd-wrt v24 std in repeater bridge mode does not function. Had do switch both devices to WPA2 personal.
Edit – ytal – Using encryption for the bridged connection only works if I either use the same encryption data (incl. ESSID) on the other (virtual) interface or do not use any encryption on the virtual interface at all. If set differently, the wireless link to the base station fails. Base station is a Speedport W500V / Targa WR 500 VoIP (http://forum.openwrt.org/viewtopic.php?id=5774) with the original Telekom firmware.
Edit – RamonBuckland – I found that setting the security to off worked first. But WPA2 Personal did not. I then lowered the key refresh to 15 seconds (same Wireless Security settings tab) on both routers and applied. They then found each other. One would figure if I were patient enough (to wait 3600 seconds, 1 hour) then it would have worked. So .. I think the key renewal is what throws them. I have it now working WPA2 Personal (AES) with a key renewal of 15 seconds. Perhaps upping it now to an hour and walking away (from the house) they will work :-) logically. Good work peoples.
Edit – MikeMaven – I’d just like to add my own confirmation. I was having problems with WPA2 at first. I think it was a result of the key refresh not occuring. I set it to 15 seconds, reconnected, and everything seems to be working great! For the record, I’m connecting to a 2wire AP using WPA2-Personal and the same key on both the physical and virtual interface.
[edit]Accessing Both Routers?
Since all routers are on the same subnet, you will be able to access both of the routers when connected to either of them.
[edit]MAC Filtering
For those of you who have enabled MAC filtering on your Primary router, you need to add the WLAN MAC address of your Secondary router to the permitted MAC filter list of the Primary router. This is different than the MAC address printed on the bottom of the case, you can find it by going to Status->Wireless and the top line will list the internal MAC address. Of course, you will want to add the MAC filter list to the Secondary router. This should be setup prior configuring your WPA, WPA2, etc. settings otherwise you will spend some time pondering why the bridge isn’t working.
[EDIT - Redhawk] – The wording here was a little confusing. Once I used the Wireless MAC address then all worked correctly….the MAC filter address on the Primary router needs to be the “Wireless MAC” address listed on the Router Status page and not the LAN MAC address . (Use Router MAC +2) – Yes…I know it says WLAN but for an noob doing this procedure it could be confused.

Special thanks to Griminal for providing a basic graphic which I modified for this Wiki Entry.
IF YOUR ROUTER WIRELESS KEEPS DISCONNECTING PLEASE CHOOSE REPEATER AND NOT REPEATER BRIDGE
[edit]Site Survey Adjustment
Site Survey does NOT create any connection. It only fills in the name of the primary router, which you must save for site survey to have any use. You can fill in the primary SSID simply by typing it in on the secondary router instead of using site survey to type it for you.
You can verify that the Bridge is using correct settings by looking at the Status -> Wireless page on the Bridge where it will show details of the SSID, channel, and encryption in use. The real indicator of proper association is on the Access Point, where the Bridge’s MAC should appear on AP’s list of active clients (also Status -> Wireless if the AP is running dd-wrt).
