Router FAQs

What is an IP Address?

An IP (Internet Protocol) Address is a numerical assignment for each device (cell phone, iPad, laptop computer, printer etc) inside a network that uses the Internet Protocol for communication. Internet Protocol is responsible for routing information packets across network boundaries. It is the main protocol establishing the Internet.

An IP address serves two predominant functions. First is to host or network interface identification. Second, it provides location addressing. To put it bluntly, an IP address tells wherever you are connecting, to whom you are visiting, and where you are located.

What is DNS?

DNS (Domain Name System) is a protocol within the TCP/IP protocol that uses a set of standards for how computers exchange data on the Internet and on many private networks.

The basic job of DNS is to convert a user-friendly domain name into an IP address that computers use to identify one another. Think of DNS like your cellphone contact list; you tap the name and the phone contacts to a phone number.

It is easier to remember flashrouters.com, rather than its IP address. Imagine if you had to remember all of the IP addresses of your favorite websites!

What is DNSMasq?

DNSMasq is a local DNS server that speeds up host-name searches from your computer/Internet connection after pressing enter.

Basically, DNSMasq gives the router some advanced enterprise functionality – caching DNS records locally so you have a faster browsing experience. Your computer only has to go to the router instead of repeatedly scouring the web for a commonly visited site.

What is Throughput and How Do I Improve it?

Throughput is the average rate of successful delivery of messages through a network. Simply put, throughput measures the speed of message delivery inside a network. If you think about it in relationship to networks and Internet connections, throughput defines the user experience. The key to a pleasing user experience is uninterrupted service and smooth data transfer.

In order to improve throughput,  you should get a router with more memory. If you notice that your network is running slowly due to congestion, you could probably benefit by upgrading your router to one with more memory. FlashMemory and RAM on a router add more room to prevent network congestion and improve throughput.

Most of FlashRouters‘ high-end units come with at least 8 MB of Flash memory and 64 MB of RAM which should be more than capable for providing for the average home users’ or small business will need in the future.

What is PPPoE?

PPPoE stands for Point-to-Point Protocol over Ethernet, a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It is used mainly with DSL services where individual users connect to a DSL modem over Ethernet.

With PPPoE, users virtually “dial” from one machine to another over an Ethernet network, establish a point-to-point connection and then data packets are securely transported through the connection.

PPPoE offers an Internet service provider (ISP) an easier way to track exactly how much bandwidth you are using in case they want to charge for it in the future.

What is the Difference Between VPN Encryption and Wireless Network Security?

VPN Encryption: If you are connected to the VPN on your home network, then any data that flows over the Internet is entirely encrypted whether you are connected to the Internet either wired or wirelessly. This means that if your Local ISP was trying to see what you are browsing or downloading, they would not be able to see your data.

Wireless Network Security: If you leave your wireless network open or insecure, it does not matter whether Internet traffic is encrypted, because someone can directly see what you are doing on your network, or even worse, can go in and put a wireless password on your network, locking you out. They may also be able to access folders and files on your computer without your control.

Best thing to do is protect your wireless network with a WPA secured password along with your VPN connection.

Are FlashRouters Affected By the Shellshock Bug?

No.

According to our in-house testing and multiple DD-WRT community reports, we have found that the Shellshock vulnerability will not work on with DD-WRT or TomatoUSB installed router. The vulnerability is based on a shell called BASH (Bourne Again Shell) but DD-WRT & Tomato firmware use BusyBox which is confirmed to not have this issue.

Please be advised that if you are using Optware on your DD-WRT router there is a chance that implementation is BASH based. Only used trusted optware on your router.

Which DD-WRT wireless extender setup should I be using?

· ·

FlashRouters supports four unique DD-WRT wireless extender setups – options similar to an open source Mesh network. Each different wireless extender configuration serves a different purpose. Read below to see which guide fits your configuration requirements!

Wireless Repeater

Why should I choose Wireless Repeater Setup?

  1. If you have a MiFi wireless only internet connection or other type of WiFi internet where there is no access to any ethernet port for a wired internet connection, then you can setup a wireless repeater network to both extend WiFi and add wired connection capabilities.
  2. If you have a large home or office area that requires additional WiFi coverage can use a wireless repeater setup to extend the existing network.
  3. If you want to create a separate VPN WiFi network in your home without placing the FlashRouter in the same room as your primary router you can use wireless repeater to establish a WiFi internet connection and then connect to VPN on your WiFi repeater network.
  4. If you want a wireless Dual Router setup option where you can have local ISP IP address through your main router WiFi network and your VPN IP address through your FlashRouter Wireless Repeater WiFi network, both available for you to connect at all times. Each network is on a unique subnet.

View the FlashRouter Wireless Repeater Setup Guide.

Wireless Repeater Bridge

Use Cases

Wireless Repeater Bridge Setup

  1. Anyone that needs all their devices connected to the same local network.
  2. Anyone with a MiFi internet connection that does not have an ethernet port and has no need for VPN.
  3. Anyone with a large wireless area that requires additional coverage.

Wireless Client Bridge

Use Cases

Wireless Client Bridge Setup

  1. Anyone with a MiFi internet connection that needs wired access.

Why can’t I access router settings?

· ·

Be sure to first try the preset details to access your FlashRouter’s settings.

First time setup

Are you connected to the FlashRouter's network?

In order to access the FlashRouter’s settings you need to be connected to the FlashRouter’s network via ethernet or WiFi.

It is possible that if you are connected to the FlashRouter’s network you device might have static IP settings from a previous connection preventing it from being read correctly. Check your device’s static IP settings before proceeding.

Is your FlashRouter wired correctly?

Your FlashRouter should be wired as detailed in our Connect FlashRouter to the Internet setup.

A common mistake is to connect from your modem or other router to a LAN/numbered port of the FlashRouter instead of the WAN/Internet port of the FlashRouter as it should be. Doing so results in no access to the FlashRouter’s settings.

Lost access

How to find you FlashRouter's Local IP Address?

It is possible that your Local IP Address was changed at some point. Your Local IP Address is the address that you can access the FlashRouter’s settings with. We recommend finding the Local IP Address of the FlashRouter.

Was your FlashRouter reset?

If your FlashRouter is showing a local IP Address of 192.168.1.1 and you are seeing ‘dd-wrt’ as an available network in your wireless networks, your FlashRouter was reset. Reconfigure your FlashRouter.

Keep in mind that seeing a Local IP Address of 192.168.1.1 can also mean your are wired incorrectly and the router has not been reset. Be sure to check your wireless networks for ‘dd-wrt’. If the FlashRouter’s wireless network name appears as it was set then your FlashRouter was not reset and you should see the above section.

Tried updating firmware

Why can't I access my FlashRouter after a firmware upgrade?

When performing a firmware upgrade there is a dropdown that has Don’t Reset or Reset to Default settings as options.

If you accidentally selected Reset to Default settings you will need to reconfigure your FlashRouter.

If you had Don’t Reset selected and are still unable to connect to the FlashRouter’s network after a firmware upgrade, first make sure you are connected to the FlashRouter’s network as WiFi can disconnect during an upgrade, and then Reboot the FlashRouter.

VPN FAQs

General VPN FAQ Answers

What is a VPN?

VPN is an acronym for ‘Virtual Private Network’, historically used by private organizations to seamlessly link geographically diverse locations via the Internet. A VPN ‘tunnels’ traffic between two devices by transmitting it over a secure network. There are also clearly identifiable benefits to individual Internet users accessing a VPN.

  • A VPN provides you with top-level security and privacy for all your Internet downloading, streaming and browsing. As long as you are signed into your VPN account, all data you transmit over the Internet is encrypted.
  • A VPN encrypts your device by hiding the IP address assigned by your Internet Service Provider (ISP) and replacing it with the IP address of your choosing from the list of server locations belonging to your VPN provider. This masks your identity when visiting sites that geo-restricted content, and helps you avoid devious local Internet marketing and advertising schemes that track you through your IP address.

Will a FlashRouter with a built-in VPN client speed up my connection?

FlashRouters are relatively new models that may enhance data transfers across your home network or extend the range of your Wireless signal. However, the speed at which you download or stream content can not exceed the speed of the connection you pay for through your ISP. Purchasing a FlashRouter or signing up for VPN service WILL NOT transform your regular connection into a high-speed broadband connection.

At the same time, if you do have a broadband connection, a FlashRouter with a VPN connection may slow down your transfer speeds due to the processor encrypting all of your data. In certain cases a FlashRouter with a VPN can also prevent throttling by an ISP of specific service like Netflix or Amazon Video.

Which VPN provider should I use?

Our routers have been tested to perform with many of the most popular VPN providers such as ExpressVPN, NordVPN, IPVanish, PrivateInternetAccess & CyberGhost among 50+ VPN providers so that subscribers can get the maximum benefit from their VPN service. If you prefer another provider, that is not an issue at all. You can still use a DD-WRT VPN FlashRouter with any VPN provider that offers DD-WRT router integration support. Contact our team for further information about using our routers with your VPN service of choice or if you need a VPN provider recommendation based on your location.

Should my FlashRouter replace my old router?

A FlashRouter will work as a standalone router by connecting your modem to its Wide Area Network (WAN) port, or using it in a Dual Router Network by connecting it to your existing router through a Local Area Network (LAN)/Ethernet port. Either way a FlashRouter can be configured to tunnel all traffic through the VPN server of your choosing.

If you would like to set up your Home Network so that some devices are being tunneled through a VPN server, and others are connecting to your Internet Service Provider (ISP) within your home country, then using your FlashRouter as an auxiliary device is recommended.

VPN Security FAQ Answers

Can I change my IP address to one in another country?

YES! The countries that you can change your IP address to depend on the offerings of your specific VPN providers. Prices and server locations vary across all VPN providers.

If you choose to purchase a FlashRouter then you will not have to install any VPN client software on your computer to change your IP address; the VPN will already be configured within the router. Therefore, any device you plug into this FlashRouter is automatically assigned the IP address of your selected VPN server.

When is my connection secure?

As long as the VPN account preset into your FlashRouter is active, any device that is connected to the Internet through this router has its network traffic encrypted, and IP address masked. With a FlashRouter you never have to physically login to your VPN account, as the settings have been stored in the router’s DD-WRT firmware.

Don’t worry though! If you are not at home, and using Wi-Fi in a public location, you can still use your VPN account on a laptop or mobile device through various other methods.

How can I be sure my connection is safe and encrypted?

In order to make sure that the connection on your FlashRouter is being rerouted appropriately through your VPN service, visit What is my IP address and make sure the location listed is the one you have chosen in your VPN settings, NOT your actual location.

If you wish, there is an Internet Kill Switch available as well for your router which will block the internet whenever you disconnect from VPN.

What VPN connection standards are supported on a FlashRouter?

Currently we support the OpenVPN protocol for VPN client connections. PPTP VPN has been deemed as insecure by the privacy community and so we no longer offer support for PPTP VPN connections.

Technical VPN FAQ Answers

What operating systems do you support?

A FlashRouter can be used with any operating system, be it Windows, Mac OS or Linux. A FlashRouter can also be used as a wireless access point for iPhones, iPads, and Android devices.

Our routers also work in conjunction with any other brand of router of ADSL or DSL modem/router combo from ISPs across the world.

Can I set up a VPN on a PS4, Xbox One, Kindle Fire, Roku, AppleTV or other devices without native VPN support?

THAT’S WHAT WE ARE HERE FOR!

If you purchase one of our FlashRouters loaded with DD-WRT firmware, you can run the client VPN connection from your router. Once you do this every device connected to the router will tunnel through the VPN.

Now you can stream content like Netflix, BBC iPlayer, Pandora Hulu, or Amazon Instant to your TV through any of these devices, instead of being constrained to streaming content on your computer!

If you need a recommendation for a VPN service with a specific streaming platform do not hesitate to contact our support team.
