Linksys MX4300 AX4200 Tri-Band WiFi 6 DD-WRT FlashRouter
Linksys MX4300 with DD-WRT Firmware: Powerful Tri-Band WiFi 6 Built for VPN
Take your home network to the next level with the Linksys MX4300 AX4200 Tri-Band WiFi 6 DD-WRT FlashRouter. Powered by a 1.4 GHz quad-core Qualcomm processor, an impressive 2 GB of RAM, and 1 GB of flash storage, the MX4300 provides the hardware power and flexibility needed for advanced networking, VPN connections, streaming, gaming, and busy connected homes.
FlashRouters upgrades the Linksys MX4300 with open-source DD-WRT firmware, unlocking advanced networking features far beyond standard factory firmware. DD-WRT includes support for both OpenVPN and WireGuard VPN client connections, allowing the MX4300 to work with many popular VPN providers, including NordVPN, Proton VPN, Surfshark, IPVanish, and more.
Instead of installing VPN software separately on every phone, computer, streaming device, or smart TV, connect compatible devices to your FlashRouter and manage the VPN connection directly from the router. This makes the MX4300 an excellent choice for users who want whole-network VPN protection combined with the speed and efficiency of WiFi 6.
AX4200 Tri-Band WiFi 6 Performance
The Linksys MX4300 combines three WiFi bands for up to 4.2 Gbps of total wireless capacity. Its tri-band WiFi 6 design gives you one 2.4 GHz band and two separate 5 GHz bands, providing additional wireless capacity for homes with many connected devices.
- Tri-Band WiFi 6: One 2.4 GHz radio plus two 5 GHz radios.
- AX4200 Wireless: Up to approximately 600 + 1200 + 2400 Mbps across the three bands.
- OFDMA Technology: Designed for more efficient communication with multiple WiFi 6 devices.
- 4x4 High-Band 5 GHz Radio: Adds additional wireless capacity for demanding devices and applications.
Whether you're streaming 4K video, gaming, working remotely, downloading large files, or connecting dozens of smart devices, the MX4300 provides significantly more wireless capacity than a traditional dual-band router.
Serious Hardware for DD-WRT
Open-source router firmware can benefit greatly from additional processing power and memory, and the MX4300 delivers substantially more hardware resources than many mainstream consumer routers.
- Processor: Qualcomm IPQ8174 1.4 GHz Quad-Core CPU
- Memory: 2 GB RAM
- Flash Storage: 1 GB NAND Flash
- WiFi: AX4200 Tri-Band WiFi 6
- Ethernet: 1 Gigabit WAN + 3 Gigabit LAN Ports
- USB: 1 USB 3.0 Port
The combination of a quad-core ARM processor and generous memory makes the MX4300 particularly attractive for users who want to take advantage of DD-WRT VPN features, advanced routing rules, multiple wireless networks, and other custom networking functionality.
A High-Performance VPN Router
With DD-WRT installed, the Linksys MX4300 can establish a VPN connection directly at the router level using WireGuard or OpenVPN.
Router-level VPN connections are particularly useful for devices where installing a traditional VPN application is difficult or impossible, including:
- Smart TVs
- Apple TV and other streaming devices
- Roku and Fire TV devices
- Game consoles
- IoT and smart-home devices
- Computers, tablets, and mobile devices
Depending on your VPN provider and DD-WRT configuration, you can protect connected devices without having to configure VPN software individually on every device.
Compatible with Popular VPN Providers
DD-WRT supports industry-standard VPN protocols rather than locking you into a single VPN company. The MX4300 can be configured with many VPN services that provide standard OpenVPN or WireGuard configuration support.
Popular compatible VPN providers include:
- NordVPN
- Proton VPN
- Surfshark
- IPVanish
- Private Internet Access
- Windscribe
- and many other OpenVPN or WireGuard-compatible VPN providers
VPN protocol availability and router configuration requirements vary by VPN provider and subscription.
Supercharge Your Router with DD-WRT
Router manufacturers typically design factory firmware for simplicity. That works well for basic networking, but advanced users often need greater control over their network.
FlashRouters transforms the Linksys MX4300 into a powerful, multi-purpose router by installing and testing DD-WRT open-source firmware before the router ships to you.
DD-WRT gives users access to advanced networking functionality, VPN client and server options, custom DNS settings, advanced WiFi configuration, VLAN and network controls, and numerous other features unavailable or limited in standard consumer firmware.
