Redirected from D-Link DIR-6** Step-by-step guide to Repeater Bridge

This guide will teach how to properly install a D-Link router of the DIR-6xx series as a Repeater Bridge (to expand the wi-fi signal).

Step-by-step guideEdit

This guide was written while using a DIR-615 D2, and also a DIR-600 before, so this guide should apply to the 600 too.

router A = router connected to internet, with wireless capability – router B = DD-WRT installed router

Recommended browsers: Opera, Firefox or Chrome

Setting up router AEdit

  1. Check the IP of router A by connecting to it by a cable (not wi-fi)
    It can be something like or; this guide will be presume it's the latter.
    Connect to it by going to
  2. Check the range of DHCP, it can be to (max 100 clients). The reason this is checked is so that you can avoid this range when setting a static IP to your laptop/computer later.
  3. Disable wireless security on router A (this will be re-enabled later)
  4. Ensure SSID is not hidden/SSID broadcast is enabled.
  5. Give the laptop/computer a static IP of (for example), with Gateway and DNS set to

Setting up router BEdit

  1. Now connect the laptop/computer to router B instead
  2. Ensure everything is reset to default. For the DIR-615 it's suggested once it's turned on and booted up, to hold down the reset button for 5-7 seconds. This will also default the router to with the DD-WRT firmware installed.
    Note: there's no need for a 30/30/30 reset.
  3. Change router B to an IP of, Gateway and Local DNS to and apply.
  4. Login to router B again at the new IP (

Checking if router B sees router AEdit

Before setting up the repeater bridge, it's advisable to check if router B "sees" router A.

  1. Go to Status / Wireless, down the bottom of the screen you will see a button labelled "Site Survey". Click it, wait, and you should see the SSID and channel number for router A, along with a bunch of random neighbours.

Creating the repeater bridgeEdit

  1. Start setting up your (soon to be) repeater bridge by going in the Basic tab:
    - WAN, Connection type: Disable
    - Router name: whatever you want
    - Local IP:
    - Subnet:
    - Gateway
    - Local DNS:
    - Assign WAN Port to Switch: ☒ (tick this)
    - Time settings: optional
  2. Disable everything related to DHCP
  3. Click 'Save' only - the settings will be applied late.
  4. Go to the Wireless/Basic Settings tab
    - Wireless Mode: Repeater Bridge
    - Wireless Network Mode: Mixed (if both routers handle b,g,n [802.11])
    - SSID: must be the SAME as router A
    - Channel: must be the SAME as router A
    - Channel Width: 20 MHz
    - SSID Broadcast: Enabled (disable later if you want)
    - Network Configuration: Bridged
  5. Save this
  6. Go next to Wireless / Wireless Security and set the Security Mode to 'Disabled' (it will be enabled later on both routers) and save
  7. Go to Services / Services and disable 'DNSMasq', then save
  8. Go to Security/Firewall and first uncheck everything except 'Filter Multicast', then set the SPI Firewell to 'Disabled'. Save it.
  9. Go to Setup / Advanced Routing: set the Operating Mode to 'Router' and the Interface to 'LAN & WLAN'.
  10. Go to Administration / Management and at the bottom of page click on Apply Settings.

The endEdit

That's it, you should now be able to connect to router A and the Internet, from router B, without a cable.

If you want to connect to router B over wi-fi, you will have to add a Virtual Interface, which is done easily in the Wireless tab.

You can now re-apply security to router A, then router B. You might need to power down router B once or twice for it to sync up correctly. It's also possible to hide both SSIDs now.

Remember: most people leave their router's IP at default. So router A would be, router B would be, and the PCs would either use DHCP or start at, for example,
