How to double your internet speed?

Following the advanced features of Load Balancing and Failover with multi-WAN, DrayTek have developed another feature, WAN Aggregation. This feature aggregates the bandwidth of the attached WAN connections to provide a higher speed Internet link.

This is very useful for businesses who need higher Internet speed to provide every user with sufficient WAN speed. For example, if you are the owner of a Café that provides free or paid Wi-Fi Hotspot, and your Internet capacity is limited to the ADSL speed at your location. Now you can aggregate 2 or more ADSL or 4G mobile services to increase speed for each of your clients.

The screenshots of Speed Test below shows how this new feature works. These are based on the Vigor3900 router in our office with 2 ADSL connections from 2 different ISPs: Internode ADSL on WAN1 and Telstra ADSL on WAN2.

The first screen shot shows WAN1 has a speed of 10.56 Mbps downlink and 0.85Mbps uplink, while the second screen shot shows WAN2 with an uplink speed of 11.83 Mbps and a downlink speed of 0.78 Mbps.

Without Session Based Load Balance enabled, the maximum speed will be that of a single WAN connection. However, once Session Based Load Balance is enabled the Internet traffic will be sent over both WAN connections simultaneously achieving the combined total of each WAN interface speed.

So with WAN Aggregation we now get 22.58Mb/s download speed and 1.68Mb/s upload speed, as shown in screen shot 3. This results in faster and more responsive Internet access for every client on your Hotspot network.

At the moment, the WAN Aggregation feature has been developed for Vigor3900, Vigor2960 and Vigor2925 series. It is expected to cover additional router models in the future. The firmware is in Beta version as of early Feb 2016; however, this is expected to become formal in the coming months.
