All FlashRouters are compatible with all ISP service types such as fiber, cable, DSL, and satellite. As long as you have a modem, modem/router, or router capable of an ethernet connection your FlashRouter will have no problems connecting to the internet.

Internet Service Providers (ISP) include a modem or modem/router combo to connect your network devices to the internet. In some instances your ISP will provide a separate router as well as the modem. You can replace this router with a FlashRouter or use both in a dual router setup.

If you would like to replace your outdated router or avoid paying to rent a router from your ISP then you should use a FlashRouter as the only WiFi device in your network.

In a single router setup the FlashRouter will be wired directly to your modem via ethernet cable and will be the only router in the setup.

Wire an ethernet cable from an open ethernet port on your modem to the WAN/internet port of the FlashRouter.

On Asus FlashRouters the WAN/internet port will be blue.

On Linksys FlashRouters the WAN/internet port will be yellow.

On Netgear FlashRouters the WAN/internet port will be yellow.

Once you have properly connected an ethernet cable from your modem into the FlashRouter internet port you must power cycle your network devices to establish an internet connection.

1. Power off your ISP modem and the FlashRouter.
2. Power on the ISP modem and wait for it to fully boot up.
3. Power on the FlashRouter.

If you would like to keep your existing WiFi network in place, and simply want to add in a VPN WiFi network with a FlashRouter then you can do so using a dual router setup. No settings in your existing network router need to change to add a FlashRouter in a dual router setup. Since we preset all FlashRouters to a unique Local IP Address, there won’t be a conflict with your existing router.

In a dual router setup the FlashRouter is wired to your existing router via ethernet cable and you will have two completely segmented WiFi networks available.

Remember if your existing router is connecting to the internet without issue already, make sure to keep the ethernet cable between your modem and existing router internet port in place.

Now connect another ethernet cable from a LAN/numbered port on your existing router to the WAN/internet port of the FlashRouter.

Reference the images above to see your WAN/internet port color.

Once you have properly connected an ethernet cable from your existing router into the FlashRouter internet port you must power cycle your network devices to establish an internet connection.

1. Power off your ISP modem, existing router, and the FlashRouter.
2. Power on the ISP modem and wait for it to fully boot up.
3. Power on the existing router and wait for it to fully boot up.
4. Power on the FlashRouter.

Once the power cycling steps are complete and the FlashRouter is powered up, start connecting your internet capable devices via ethernet or WiFi. Visit any website and make sure the page fully loads.

DD-WRT open source firmware removes many firmware vulnerabilities and backdoor access issues that may cause problems in stock firmware. DD-WRT is also updated more frequently than stock firmware, so be sure to always check with the FlashRouter support team to see which DD-WRT build we recommend for the highest level of security for your router at any time.

Aside from avoiding common issues and flaws with stock firmware, DD-WRT give you more control over the firmware settings and allows you to take some extra steps to really lock down your network security. In this article we highlight additional options for WiFi network security and also preventative measures for remote execution attacks.

1. Set Use Filter to Enable.
2. Select either Prevent or Permit
   • Choose Prevent to add MAC addresses that you don’t want to join your network.
   • Choose Permit to add MAC addresses that you do want to join your network, automatically blocking all others.
3. Select Edit MAC Filter List.
4. Add the MAC Address of the wireless devices you want to prevent or permit. Be sure to use the xx:xx:xx:xx:xx:xx format. Hint: You can see a list of connected devices MAC Address by clicking Wireless Client MAC List.
5. Click Save.
6. Replicate the steps above for each wireless band.
7. Click Apply Settings.

1. Set SNMP to Disable – this setting disables Simple Network Management Protocol, which prevents software from polling your network for information about connected devices.
2. Set SSHd to Disable – disabling the Secure Shell is a simple way to prevent root access and brute force attacks on your network.
3. Set Telnet to Disable – Telnet is a less secure version of SSH to manage your local router network via command line.
4. Click Apply Settings.

1. Set Web GUI Management to Disable.
2. Set SSH Management to Disable.
3. Set Telnet Management to Disable.
4. Set Allow Any Remote IP to Enable – Even though this setting is set to Enable there is no remote access because Web GUI Management is already set to Disable. 
5. Click Apply Settings.

Most ISPs only support IPv4. Unless your ISP supports IPv6 then enabling it on the FlashRouter will not enable it across your network.

For most VPN users IPv6 should remain disabled as the VPN connection was designed to operate under IPv4 addresses only. Enabling IPv6 in this instance may compromise the security of the VPN tunnel.

We typically only recommend enabling IPv6 if you are not using VPN or if your VPN provider requires that IPv6 be enabled.

1. Set IPv6 to Enable.
2. Select Native IPv6 from ISP in the dropdown.
3. If you have specific IPv6 DNS servers you would like to add you can add them in the Static DNS fields or leave those fields blank.
4. Click Apply Settings.

Power your FlashRouter off and then power it back on by unplugging and then plugging it back in or using the button on the back of the FlashRouter.

Once the FlashRouter is finished powering back up, connect one of your devices to the FlashRouter via Ethernet or Wireless.

Visit  http://ipv6-test.com/ where you should see Supported under IPv6 connectivity if your ISP supports IPv6 and your modem is setup to passthrough IPv6.

Most ISPs do not require PPPoE credentials. If you are certain this is an ISP requirement in your setup, we kindly ask that you get in touch with your ISP to verify that they do in fact require PPPoE authentication and to provide you with the correct credentials to enter into your FlashRouter.

Before you enter your PPPoE credentials, you should have already setup your FlashRouter in a Single Router Setup with correct wiring. Once you enter PPPoE credentials you should then be able to connect to the internet.

If you are using a Dual Router Setup there is no need to enter PPPoE credentials if they are already entered in the existing router. You can disregard this article.

1. Set the Connection Type dropdown to PPPoE.
2. Enter your ISP assigned PPPoE username and password.
3. Click Apply Settings.

1. Power off your ISP modem and the FlashRouter.
2. Power on the ISP modem and wait for it to fully boot up.
3. Power on the FlashRouter.

Once the FlashRouter is booted up connect one of your devices to the FlashRouter via Ethernet or Wireless.
