Top 3 Reasons For A Wireless Router Upgrade


Assuming that a wireless router is a set-it-and-forget-it device is an increasingly bigger security risk. If you are truly interested in the best performance and maximum privacy, vigilant monitoring of your home network is a must.

Older wireless routers are often the culprit when network security or WiFi performance problems arise due to unfixed manufacturer flaws or outdated hardware performance.

When issues are consistently occurring, a wireless router upgrade can be the cure!

The Importance of A Wireless Router

A wireless router is the centerpiece of any home network. Every device that uses a connection to the Internet takes advantage of the network created by the router to get online. For more information, FlashRouters has a comprehensive overview of what a routers actually does.

Single Router Setup

A powerful wireless router provides connected devices with the speed and performance to keep activities, like Netflix streaming and online gaming, working optimally.

The speed of a wireless connection is based on a variety of factors, starting with your Internet Service Provider (ISP) package. ISPs offer various subscription packages which are differentiated by bandwidth limitations. Economy subscription packages offer slower connectivity, as ISPs incentivize subscribers to purchase advanced plans for greater bandwidth.

The second factor affecting the speed of the wireless connection of devices is the distance from the router. Simply put, devices that are closer to the router will have a stronger connection to the router’s wireless network.

Furthermore, the make and model of the router affect how fast data is processed. The number and size of antennas, the speed of the internal processing unit (CPU), and the amount of flash memory embedded in the router all affect performance.

Still unconvinced? Here are the top reasons to upgrade:

More Devices Covered

According to research, the number of devices connected to the Internet of Things will jump from nearly 27 billion in 2017 to 125 billion in 2030. Having the proper wireless network infrastructure to support more devices is critical.

Enter MU-MIMO. MU-MIMO technology (Multiple User Multiple Input Multiple Output) reduces competition between devices on the WiFi network. With a MU-MIMO router such as the Netgear R7800 DD-WRT or the Linksys WRT3200ACM, multiple devices communicate with the network at the same time.

Before the introduction of MU-MIMO, routers used SU-MIMO technology (Single User Multiple Input Multiple Output). Devices connecting to networks using SU-MIMO technology compete for connectivity, as the network processes requests on a first-come, first served basis (as shown above).

In other words, devices form a line, like people entering a theater through one door. No one can enter the theater before the previous person enters. Likewise, device requests are processed only once the router processes the preceding device’s request. Consequently, if a network has many bandwidth-hogging devices, congestion can occur. This can lead to slow speeds and subpar performance.

A router using MU-MIMO technology, meanwhile, fixes this problem by breaking up bandwidth into streams. The router processes individual streams simultaneously, allowing for more devices to connect concurrently, thereby decreasing congestion. It is as if the theater above opened two, three, or four doors, instead of one. That allows for greater speeds and better connections.

Upgraded WiFi Standards

A wireless router upgrade can help your network stay up to date with the latest wireless standards. Check out the chart below to see how some of the older wireless standards compare.

Max Throughput (Speeds):54 Mbps900 Mbps5300 Mbps7200 Mbps10000 Mbps
Max Wireless Range (Radius):75 Ft200 Ft500 Ft500 Ft500+ ft
Wireless Channel Widths:20 Mhz20/40 Mhz20/40/80/160 Mhz5/10/20 MhzUp to 160 Mhz
Wireless Bands:One 2.4 Ghz (Single Band)One 2.4Ghz & One 5 Ghz (Dual Band)One 2.4 Ghz & Two 5 Ghz (Tri-Band)One 2.4 Ghz, Two 5 GHz Bands, & 60 GHz Bands (Quad-Stream)One 2.4 Ghz, Two 5 Ghz Bands

As shown above, newer wireless standards allow for more device connections thanks to additional wireless bands. Wireless-AD expands on Wireless-AC by adding another wireless band. The new 60 GHz band allows for short range, powerful connections, reducing the load on other bands. Less load means that devices have a longer lifespan, saving you money.

Upgrading to a router with a newer wireless standard will extend wireless range considerably. Newer wireless routers come with more external antennas for better range and connectivity. Case in point, the Asus RT-AC5300 DD-WRT VPN FlashRouter. This customized Open Source router takes the top spot for range with eight external antennas, ensuring that any house can be covered by the network.

Better Security

Upgrading your wireless network also helps deal with the number one issue: security. Older routers are less likely to have updates and therefore have more vulnerabilities. Newer routers are more commonly updated and have better security protocols. However, even they are not free from trouble.

Recent router attacks like VPNFilter have shown that regular routers and stock router firmware are still full of security flaws and vulnerable to hacks. Plus, manufacturers are slow to respond to known flaws. So where does that leave you?

Luckily there is a open-source firmware solution like DD-WRT. It is constantly updated, ensuring that there are minimal issues and if issues do arise, they are resolved quickly. However, installing DD-WRT is difficult, time-consuming, and could leave your brand-new router nonfunctional. That’s where FlashRouters comes in! We’ll take the hassle out of upgrading your wireless network and let you enjoy your upgraded wireless network experience.

Upgrading To A FlashRouter For Maximum Performance

A wireless router upgrade is a great start, but upgrading to a FlashRouter is a more complete solution.

Preventing The New Linksys Firmware DDoS Vulnerability

Here we go again. Unfortunately, with stock router firmware vulnerabilities are nothing new. Netgear routers were recently affected by a bug in their firmware. Additionally, D-Link was affected by a vulnerability which was patched in Spring of last year. Previously, Asus was in legal trouble with the FTC for known security flaws in their firmware.

Linksys experiences bugs as well. Security researchers at IOActive are identifying several vulnerabilities in Linksys router firmware. These vulnerabilities allow hackers to bypass authentication and perform denial of service (DDoS) attacks.

The good news? Linksys is working on a fix for the vulnerabilities. The bad news? This issue affects more than two dozen models of Linksys wireless routers in the WRT and EA series. You can see the full list of in-danger models here:

From the WRT series: WRT1200AC, WRT1900AC, WRT1900ACS, WRT3200ACM

How To Stop a DDoS Attack with a FlashRouter


A distributed denial-of-service attack is a type of attack where multiple compromised systems are used to target a single system. Specifically, denial-of-service attacks disrupt a network by flooding it with useless traffic. These types of attacks can cause serious damage to a network. Moreover, hackers are always thinking of new methods for employing DDoS attacks. Looking for some methods on how to stop a DDoS attack? FlashRouters is here to help.

The Dyn DDoS Attack of October 2016

Over the last year, DDoS attacks have made the rounds on the news. A notable attack occurred on Friday, October 21st. On this date, bogus traffic hit targets belonging to Dyn, a company which provides DNS services to other companies. A DNS, or Domain Name System, sends users information requests to the correct website.  Twitter, Pinterest, Reddit, Tumblr, Spotify, and many services use Dyn as a DNS provider. As a result of the attack, these services and many others were not accessible for several hours.

The 10/21 attack was able to happen through the direction of bogus traffic towards Internet of Things devices. The Internet of Things is comprised of “smart” devices. Smart devices are everything from baby monitors to refrigerators. Essentially, any device that uses WiFi is a smart device. In our current age, nearly everything is a smart device.

Moreover, one can attempt to prevent DDoS attacks through the use of strong passwords on devices. A DDoS attack can also be prevented by disabling UPnP (Universal Plug and Play) and updating security patches as soon as they become available. However, there may be a more surefire solution…

How To Stop A DDoS Attack With a FlashRouter

Asus AC5300 - 8 External Antennas

At any rate, using a router flashed with Open Source DD-WRT or Tomato firmware is your best bet for securing your network. A router with DD-WRT or Tomato firmware voids the vulnerabilities that come with factory firmware. Furthermore, there is no chance one will encounter a factory installed backdoor. Additionally, one will not see a firmware bug from a manufacturer update using alternative firmware.

On the other hand, dealing with the specific question of how to stop a DDoS attack, integrating a Virtual Private Network at the router level will secure all Internet of Things devices. If you use a DD-WRT or Tomato router like the powerful RT-AC5300 Asus FlashRouter and integrate a VPN, all connected devices will be going through the VPN server.

As most IoT devices have no native VPN support, using a router with alternative firmware is the only way to encrypt them. Furthermore, if devices are encrypted, they will be safe from DDoS attacks.

Inteno Router Hack Allows Attacker Takeover of Your Whole Network

Inteno router hack allows takeover of network

Inteno Router Hack

Another day, and another router hack is exposed. This new Inteno router hack demonstrates once again that stock firmware is untrustworthy.

Inteno Router Hack Leaves Whole Networks Exposed

A major vulnerability that would allow hackers to potentially control the user’s whole network has been found on several Inteno home routers, per The Merkle.

F-secure researchers discovered the vulnerability. Furthermore, this vulnerability allows hackers to take full control of the router and its Internet traffic. A hacker could even install his or her own firmware.

Suffice to say, a hacker can put your network into a world of hurt by exploiting this vulnerability. All of your home devices – your phone, laptop, Smart TV, etc. – run on your router, and therefore all of your devices are at risk. This means that Inteno router owners are vulnerable to a complete network takeover. An attacker has the potential to direct users to malware-infected sites, or install backdoors on your router without your approval.

Astoundingly, Inteno has no intention of patching this flaw, at least as of this writing. This strikes us as an almost criminal display of negligence, and if Inteno maintains this position, we’d just as soon recommend avoiding their devices altogether. It is absolutely the company’s responsibility to correct this error.

How to Circumvent Inteno Router Security Flaws

ET Telecom’s article on this incident includes useful tips for keeping your network safe from this sort of flaw. Tips include keeping “browsers and other software updated to prevent hackers exploiting security flaws in old software” and use a VPN (hey, we know where you can find a lot of those!).

Avoiding routers with stock firmware is the best thing you can do for your cybersecurity. Stock router firmwares are constantly being exposed as vulnerable, and a conventional router just won’t cut it anymore. Make the jump to open source. Your security vastly improves. In fact, your whole WiFi network vastly improves.

FlashRouters avoids running into these recurring network security flaws by installing DD-WRT and Tomato on our routers. Our devices are fast, powerful, and reliable, as a result of these open source firmwares. Your Netflix streaming is dependably excellent, and your gaming suffers no buffering interruptions. Most of all, a FlashRouter is VPN-friendly, giving you that extra security a modern WiFi network demands.

Check out some of our bestselling routers, because you’ll see the ways in which your network can improve. Don’t let your network fall victim to problems like the Inteno router flaw.One can easily avoid such issues with a FlashRouter.
