How To Disable DHCP On An Edimax Router For Bridge Mode
An Edimax router can be reused as a wireless access point or bridge instead of operating as the main gateway for your network. In that arrangement, another router handles internet access, routing, firewall protection, and address assignment. The Edimax unit provides wireless coverage or connects network devices without creating a separate subnet.
Disabling the Dynamic Host Configuration Protocol (DHCP) server is usually an essential part of this setup. If two routers assign IP addresses on the same network, devices may receive conflicting settings or use the wrong gateway. The result can be intermittent internet access, failed device discovery, or difficulty opening either router’s administration page.
The exact menu names vary between Edimax models and firmware versions. Some devices include an explicit Access Point, Bridge, or WDS mode, while others require a manual configuration. The general process remains similar: connect to the Edimax router, assign it a suitable LAN address, turn off DHCP, and connect the network cables correctly.
Understand What Bridge Mode Changes
A bridge passes network traffic between two segments without acting as an independent router. When an Edimax device is used in a basic access-point arrangement, the primary router remains responsible for NAT, firewall rules, port forwarding, and DHCP. The Edimax unit simply extends the existing wired or wireless network.
The term “bridge mode” can describe several different functions. A wireless bridge may connect a remote Ethernet device to a distant Wi-Fi network. WDS bridge mode may link two compatible access points. A modem or gateway bridge mode disables routing on the gateway so a separate router can manage the connection. These arrangements are related, but their menus and cabling can differ.
If your goal is to reuse an Edimax router for additional Wi-Fi coverage, a LAN-to-LAN access-point configuration is often the simplest option. The Edimax router’s DHCP service must be disabled because the primary router already supplies addresses. If the Edimax model has a dedicated AP mode, selecting that mode may disable DHCP automatically, but verify the setting before saving.
Prepare The Network Before Editing Settings
Identify the primary router’s LAN address and subnet first. Common private gateway addresses include 192.168.1.1 and 192.168.0.1, although your network may use a different range. On a computer, this information is usually shown as the Default Gateway in the network connection details. The Edimax router needs a fixed management address in the same subnet, but that address must not be used by another device.
For example, if the main router uses 192.168.1.1 and its DHCP pool runs from 192.168.1.100 through 192.168.1.200, you could assign the Edimax device 192.168.1.2. This address is in the same network, outside the automatic pool, and easy to remember. If 192.168.1.2 is already occupied, select another unused address outside the primary router’s DHCP range.
Connect a computer directly to an Edimax LAN port with an Ethernet cable while configuring it. A wired connection reduces the risk of losing access when wireless settings change. Disconnect the Edimax router from the primary router during the initial setup if necessary, especially when both devices currently use the same default IP address.
Save the existing settings or record the current LAN address, wireless name, and security configuration. A factory reset should be a last resort because it erases customized settings. If you must reset the device, hold the reset button for the period specified in its manual, then wait for the router to restart before opening the setup page.
Open The Edimax Administration Page
Launch a browser on the directly connected computer and enter the Edimax setup address. Depending on the model, this may be http://edimax.setup, 192.168.2.1, 192.168.1.1, or another address printed on the device label or documented in its manual. Do not search for the address through a public search engine; enter it directly into the browser’s address bar.
Log in with the administrator credentials. Older Edimax products commonly use a default username and password combination, while newer firmware may require a password created during first-time setup. If the login page does not load, check that the computer has received an IP address and that it is connected to a LAN port rather than the WAN or Internet port.
Find the LAN, Network, or Local Area Network settings. You may see fields for the router IP address, subnet mask, DHCP server, and address pool. Before changing the IP address, make sure it matches the primary router’s subnet. A mismatch can make the Edimax interface inaccessible until the computer is configured for the new network.
Change the Edimax LAN address if required, then apply the setting. The device may restart, and the browser session will stop responding. Reconnect to the new address after the reboot. For example, after changing the unit to 192.168.1.2, use http://192.168.1.2 to access its control panel rather than the old address.
Turn Off The DHCP Server
In the Edimax control panel, open the DHCP Server, LAN, or Network settings and locate the option labeled Enable DHCP Server. Clear the checkbox or select Disable, then save or apply the change. Some firmware presents separate Start IP Address and End IP Address fields; these fields are irrelevant once the DHCP service is disabled.
The DHCP service should be disabled on the secondary Edimax device, not on the primary router. The main router must continue assigning addresses to computers, phones, printers, cameras, and other clients. If DHCP is disabled on every router, new devices may connect to Wi-Fi but fail to obtain a usable IP address automatically.
After saving, reconnect the computer or renew its network lease. It should receive an address from the primary router. A typical result might be an IP address of 192.168.1.115, a gateway of 192.168.1.1, and DNS servers supplied by the main router or internet provider. The Edimax management address, such as 192.168.1.2, remains available for future administration.
Avoid enabling DHCP on both devices as a temporary test unless they are intentionally configured as separate networks. Two DHCP servers can respond to the same client request, producing inconsistent gateways and DNS settings. This often appears as a network that works briefly and then loses connectivity.
Configure The Physical And Wireless Connection
For a manual access-point setup, connect an Ethernet cable from a LAN port on the primary router to a LAN port on the Edimax router. Do not use the Edimax WAN or Internet port unless the model’s access-point mode specifically requires it. A LAN-to-LAN connection keeps both devices on the same local network and avoids unnecessary routing.
Set the Edimax wireless network name, security mode, and password. You can use the same SSID and password as the primary router to make movement between coverage areas more convenient, although seamless roaming is not guaranteed on basic consumer hardware. Alternatively, use a distinct SSID while testing so it is clear which access point a client is using.
For compatible networks, use non-overlapping wireless channels and matching security settings. On the 2.4 GHz band, channels 1, 6, and 11 are commonly used because they minimize overlap. Automatic channel selection may work, but manual selection can be useful when nearby networks cause interference. Modern WPA2-Personal or WPA3-Personal settings are preferable to outdated WEP encryption.
If the Edimax device is configured as a wireless bridge rather than a wired access point, select the primary Wi-Fi network as the bridge or uplink network. Enter its wireless password carefully, and disable any unrelated routing feature if the firmware permits it. Wireless bridge modes may require matching channels, compatible encryption, or WDS support on both devices.

Check For Address Conflicts And Lost Access
After DHCP is disabled and the cable is connected, restart the Edimax router and one client device. The client should obtain its network configuration from the primary router. Check the IP address, subnet mask, default gateway, and DNS information. The gateway should normally be the primary router, not the Edimax device.
Test the internet connection first, then test local access. Open the primary router’s address and the Edimax management address separately. If the primary router is 192.168.1.1 and the Edimax unit is 192.168.1.2, both pages should be reachable from a connected computer. The Edimax page may be unavailable while the device is rebooting, so allow it time to finish applying changes.
If the Edimax interface cannot be opened, inspect the computer’s current gateway and IP address. A client that has retained an old lease may need to disconnect and reconnect, restart its adapter, or renew the lease. Also verify that the selected Edimax address is correct and that it does not duplicate the primary router or another device.
A duplicate address can make both devices unstable or prevent one from loading at all. Temporarily disconnect the Edimax from the main network, connect directly to it, and assign a different unused management address if a conflict is suspected. Keep a written record of the final address so future configuration does not require guessing.
Troubleshoot Common Setup Problems
If clients connect to the Edimax Wi-Fi but show “no internet,” confirm that the Ethernet cable is connected to the correct ports and that the main router is online. Check whether the client received an IP address from the primary router. An address beginning with 169.254 usually indicates that DHCP communication failed.
If devices connected to the Edimax can access the internet but cannot discover printers, shared folders, or smart-home equipment, the Edimax may still be routing traffic. Confirm that its DHCP server is disabled and that the uplink uses LAN-to-LAN cabling. Also check for a router, gateway, NAT, or firewall mode that needs to be disabled when using access-point operation.
A wireless bridge may fail even when the password is correct if the two devices use incompatible encryption or bridge standards. Update firmware when appropriate, place the Edimax within reliable wireless range during pairing, and verify the selected upstream SSID. WDS features are often vendor- or chipset-dependent, so a wired access-point connection can be more dependable.
Use the Edimax status page to confirm link state, assigned LAN address, and wireless association. Avoid repeated factory resets while troubleshooting because each reset removes the address and DHCP changes already made. Change one setting at a time and test after each adjustment.
Recommended Final Settings
- Give the Edimax router a unique fixed LAN address within the primary router’s subnet.
- Disable DHCP on the Edimax unit while leaving DHCP enabled on the main router.
- Use LAN-to-LAN cabling for a standard access-point installation.
- Match wireless security settings and use a strong WPA2 or WPA3 password.
- Record the Edimax management address and administrator credentials in a secure place.
Once the configuration is stable, reconnect phones, laptops, printers, and smart devices to the extended network. Confirm that each device receives an address from the primary router and that local services remain available. Save a backup of the Edimax configuration if the firmware provides an export option.
If the model includes a dedicated AP or bridge wizard, compare its final settings with the manual configuration. The wizard may alter the LAN address or restart wireless services, but it should leave the primary router in control of DHCP and routing. Keep the Edimax setup guide and the chosen management address available for future firmware updates or wireless changes.
Apply these steps to your Edimax model, verify the address and gateway on a connected device, and use the working management address whenever you need to adjust the bridge or access-point settings later.
