This setup is for Access Point (AP), the device will act as router only, not gateway (WAN disabled).

Example of using AP is to extend WiFi capability for MikroTik RB750/750G gateway.

More DD-WRT AP configuration guide here.


 

Hard reset the DD-WRT device, then enter default IP 192.168.1.1

You need to assign the router admin ID and password, enter anything you like.

I personally prefer Router admin: root    password:<your choice>

 

Click on Administration, system will prompt you to login again.

 

Setup as follow:

  • Info Site Password Protection = Enable
  • Cron job = Disable
  • Routing = Disable

Click "Save" follow by "Apply Settings" when done.

 

 

Setup --> Basic Setup tab

  • WAN Connection Type = Disabled
  • Assign a fixed IP to the device, eg. 192.168.1.5  (must be same subnet segment with the main gateway)
  • Enter the gateway IP, eg. 192.168.1.1
  • Disable DHCP

Click "Save" follow by "Apply Settings" when done.

 

Assign fixed IP to your computer, eg. 192.168.1.9  (must be same subnet segment with the gateway & router)

Enter the device's IP which you just assigned above, eg, 192.168.1.5

Go to Setup --> Advanced Routing tab, change the "Operation Mode = Router"

Click "Save" follow by "Apply Settings" when done.

 

Go to Services --> Services tab, disable DNSMasq, Telnet & ttraff Daemon

Click "Save" follow by "Apply Settings" when done.

 

Go to Security --> Firewall tab, setup steps as following screen.

Click "Save" follow by "Apply Settings" when done.

 

For wireless setup, I assumed only N and G devices, setup steps:

  1. Enter your preferred SSID, follow by the Network Mode, then click "Save"
  2. Select the Channel Width, the click "Save"
  3. Choose Wireless Channel & Control Channel, then click "Save" follow by "Apply Settings"

Note: Choose "Mixed" Network Mode if you have old device uses B

 

Click "Advanced Settings" and setup as follows:

  • for ACK timing, I normally enter "1" for Atheros device if intend to disable it.
  • for "Max Associated Clients", choose your own number.

Note: Disable "Short Preamble" if you have old B device

Click "Save" follow by "Apply Settings" when done
