Networking – Is it possible to combine two internet connections to increase performance

home-networkinginternetnetworking

I've got a small home network, 3 PCs plus a laptop or two when the relatives come to visit, connected to a single cable internet connection. Now, as soon as everyone starts using the 'net the performance starts to suffer and if the load is heavy enough nobody can get anything done and everyone complains. At one point it was so bad that only one of us could use it at a time. I was researching possible solutions to this problem and I heard that internet cafes that utilize 2 internet connections, possibly from different providers, and have some sort of router that allows them to split the traffic between the both of them, with online games going through one and web traffic going through another. Is this possible? What is the technical term for it, and can/should it be applied to a home network setup or is there another solution to this problem?

Best Answer

There are several possible solutions.

  1. Subscribe at your ISP to higher bandwidth - your bandwidth test results are very low.
  2. If the bandwidth should be sufficient, then get a better router (remember to convert bandwidth in Mbits to Mbytes by dividing by 8, although dividing by 10 is normally more accurate).
  3. If you still wish to combine two Internet connections, get a router that is capable of "Bandwidth Aggregation" or "Link aggregation".

For bandwidth requirements for youtube see :
How much bandwidth is required to play online YouTube videos ?

The article notes that to enjoy good HD viewing experience requires 1Mbps, while non-HD requires at least 513Kbps. Below these values, one may need to wait for the video to buffer .
