How do I set a Static IP for my device in DD-WRT?

TeamFlashRouters · May 30, 2019 ·

It can be very useful to setup static local IP addresses for devices on your FlashRouter network. By assigning specific IP’s to specific devices you can better control and manage how your network and the internet interacts with each device.

Once you setup a static IP you can set access restrictions, monitor and control bandwidth, as well as bypass a router VPN connection or setup a device specific Kill Switch. Without a static IP assignment you may lose device specific settings when the DHCP lease to the router expires.

Navigate to Services > Services

Set Static IP by Device MAC Address in FlashRouter DD-WRT Settings
  1. Under Static Leases click Add once.
  2. Fill in the newly appeared fields.
    • MAC Address: Enter the device’s MAC address which can be found on the device itself or on the Status > LAN page.
    • Hostame: Enter a name for the device. Make sure that there are no spaces.
    • IP Address: Enter the desired static IP Address of the device. It should be on the same subnet as the FlashRouter (192.168.11.x)
    • Client Lease Time: Leave this field blank.
  3. Click Apply Settings
  4. Repeat the steps above for each individual static IP address you would like to setup. If you click Add before clicking Apply Settings you will lose the configuration.

If a device has wireless and ethernet capabilities the MAC Addresses will be different for a wireless connection and an ethernet connection. Make sure to set a static IP for both MAC Addresses in this case.

Please be aware that FlashRouters is not responsible for any DIY firmware flashing updates. If you have questions or concerns contact FlashRouters Support or check out the DD-WRT Community for additional helpful resources.

Make sure you are following the directions below to load the firmware file into the router settings and not trying to open the firmware file on its own.

Access the FlashRouter via wired connection. It is possible to upgrade firmware via WiFi, but this is not recommended unless you are unable to wire directly to the router.

Navigate to Administration > Firmware Upgrade

Firmware Upgrade page in FlashRouter DD-WRT settings
  1. Do NOT select Reset to Default Settings in the dropdown menu as this will erase all of your FlashRouter settings.
    NOTE: If you are updating from an older DD-WRT build you may be required to reset the router after a firmware update for new features and UI to properly load. You will then be required to setup the administration username and password along with your WiFi and VPN network settings.
  2. Click Choose File and select the file you have downloaded.
  3. Click Upgrade.

How do I schedule a reboot of my FlashRouter?

TeamFlashRouters · May 30, 2019 ·

Schedule a reboot of the FlashRouter to restart your connection. A reboot of your network can help with stability and prevent the connection from slowing down over time.

Navigate to Administration > Keep Alive

Schedule a Reboot in FlashRouter DD-WRT Settings
  1. Enable Schedule Reboot.
  2. Select At a Set Time, and select the time of the day and day of the week you wish to schedule your reboot.
  3. Click Apply Settings.

How do I change the DHCP range of my FlashRouter?

TeamFlashRouters · May 30, 2019 ·

Whenever a device joins the FlashRouter network via wired or WiFi connection the DHCP server on the router gives out a local IP address to each device so all these devices can interact on your local network.

Increase the DHCP range to allow more users to automatically be assigned an IP address or decrease the DHCP range to limit the users that are automatically assigned an IP address.

Navigate to Setup > Basic Setup

Change DHCP Range in FlashRouter DD-WRT Settings
  1. Under Network Address Server Settings (DHCP) change the Maximum DHCP Users to your preferred value.
  2. You can edit the Start IP Address to 2 and Maximum DHCP Users to 254 for the most available slots.
  3. Click Apply Settings.
