Using 4g network hotspot and regular lan internet simultaneously

post #1 of 4
Thread Starter 
I was wondering if anyone knew how to use the 4g internet on their phone in order to boost bandwidth, and/or lower ping on my pc computer with a regular internet connection. I usually get about 1.5 mb/s download on my mobile 4g and 3mb/s from comcast, so assuming maximum efficiency I could theoretically see a bandwidth increase of 50%. Is there some app or program that can do this?

You'll need some third-party software to load balance the connections. Remember that you will never get more speed than the highest connection available. Combining a 3mbps and a 1.5mbps will get you 3mbps balanced across two connections, not 4.5mbps. It may improve your latency but it will not increase your max speeds.

Connectify Dispatch is an option. It isn't free and I don't know of any free or open source alternatives.

Edit: Dispatch claims to increase your bandwidth, so I should explain a bit more: and it will, by enabling multiple connections to the same content, but your bandwidth is unlikely to go over your 3mbps. You will see faster speeds simply because most of the time you aren't getting your full speed because it is limited by the other end of the connection, but a second, load balanced connection tricks the other end into thinking you are two different people. Much like download managers like DownThemAll do for individual files, segmented. Dispatch does this for all incoming data on your combined connection.

^^^^ This is 100% correct, partly. =)

If you're attempting to increase the speed of a single TCP/IP connection, say a FTP download from Microsoft to your PC, then no - you can't increase the speed beyond what a single link will provide. That's because when the TCP/IP connection is established, the source and destination MAC addresses are used to route the signal between your computer and the remote computer. Unfortunately in this situation, the MAC address resolves to only ONE of your network interfaces - either the 4G, OR the Comcast link - not both.

IF, however, you're attempting to increase the speed of something like a Torrent or a peer-to-peer download of something like World of Warcraft, through the Blizzard P2P downloader, then yes - it will give you faster speeds. That's because in this case, you're opening many TCP/IP connections to multiple hosts elsewhere on the Internet simultaneously. Some connections will go over the 4G, some will go over the Comcast link, but none of them will go over "both" at the same time.

Sorry about that, hammong. I thought better of being terse and explained it a bit more in an edit before you posted. Glad you clarified it more on the TCP/IP layer though. I learned something smile.gif
