blogger /

Buffalo WZR-HP-G300N & WHR-HP-G300N are high power routers and access points. The routers are powered by wireless n technology with DD-WRT Linux based open source firmware – ideal solutions for high-speed and large homes network coverage.

Should you build a wireless network environment for your large home for heavy duty applications such as streaming video and gaming, you need to search high performance wireless routers in delivering high speed and longer distance coverage. For heavy duty tasks, your router should be powered by the latest wireless technology for high-speed and longer distance coverage. The router should also include the Quality of Service feature to prioritize the video and gaming traffic.

Generally the high performance and high power routers are more expensive than ordinary home routers. Should your budget is limited; consider affordable high-performance routers: Buffalo WZR-HP-G300N & WHR-HP-G300N wireless routers.

Why Buffalo WZR-HP-G300N & WHR-HP-G300N?

Unlike high performance home wireless routers, the WZR-HP-G300N & WHR-HP-G300N are embedded with DD-WRT which means the routers are based on Open Source Linux firmware. DD-WRT is a Linux based alternative Open-Source firmware suitable for many types of wireless routers and other embedded systems for providing the easiest handling even by non-technicians, high-speed, and reliable and supporting a large numbers of functionalities to fulfill the demand of professionals.

Both routers are powered by the latest wireless 802.11n technology – the fastest wireless technology available in the marketplace. The routers can deliver high-speeds of up to 300Mbps in ideal conditions (the actual speeds may vary). The routers are powered by with the High-Power technology for extended wireless coverage and performance which are ideal for internet gaming and watching videos.

Now which one is suitable for your need? As general both wireless routers have the same features for high power wireless network environment but the WZR-HP-G300N is designed for heavy duty gaming and streaming HD media contents. The following are the main different between the two routers. Interfaces

The WHR-HP-G300N routers are equipped with the 10/100 Mbps Ethernet ports but the WZR-HP-G300N routers are Gigabit Ethernet ports both for LAN (4xports) and WAN (1xport) interfaces. You can use the Gigabit ports for high-bandwidth applications such as video and large bulk of files transfer. Should you require high speed wired connection, the WZR-HP-G300N is your router.

Another value for WZR-HP-G300N is the USB port with AirShare technology to allow you share the external USB storage across the network and even you can access it remotely. When you upgrade the more advanced firmware, it will support BitTorent capability.

Unfortunately, you can not attach a USB printer to the USB port for sharing. Should you need to share the printer, you need to buy separate print-server or wireless print-server, unless you need to configure the printer attached to one of your computer and share it across the network. Or if your printer is embedded with the Ethernet print-server, you can connect it to one of the router’s Ethernet LAN port and configure it for sharing. To provide higher power signal you can upgrade the external antenna with the high-gain directional antenna, but this apply only for WHR-HP-G300N.

Secure guest access is only available on WZR. With secure guest access, you can provide separate internet access to your friends without compromising your internal network. For small offices deployment this feature is very important. You create separate security boundary for your visitors who need internet access with their laptops when they visit your office.

Alternative solution when you need to share the printer and the external storage across the network – you can consider Trendnet TEW-673GRU. This router includes two USB ports to allow you share a USB printer and an external USB storage at the same time.
