how to combine 2 internet connection together so internet can share better

Yes, with some limitations. What you're looking for is a "load balancing router". For example:

Methinks the Edimax BR-6641 (2nd URL above) is the more appropriate device. It will take up to 4 WAN connections and conglomerate them into a single LAN connection. They can be a mix of cable, satellite, DSL, ISDN, whatever, or all the same type. The traffic load will be roughly equally distributed among these 4 WAN connections.

That's the good part. Now, the limitations. It will NOT combine 4 different IP's into a single stream. Therefore, if you have 4 different DSL lines at 1.5Mbits/sec each, you will NOT get 6Mbits/sec download speed from a single download. You'll get 1.5Mbits/sec and no more. The same applies to uploads to a single IP address. However, you can do 4 independent downloads, from 4 different servers, and get an aggregate speed of 4 times the 1.5Mbits/sec speed of a single connection.

Where such routers work best is situations where you have multiple users doing different things and needed more aggregate bandwidth. That sounds like your situation.

However, it's possible that you don't need a load balancing router. Have you looked into QoS (quality of service)? It might be that one of your multiple users is doing something that is screwing up the performance for the others. For example, if your broadband connection is asymmetrical (most are), a user hogging all your outgoing bandwidth (as in peer-to-peer file sharing) will saturate your outgoing bandwidth. With the ACK's on downloads being lost by this outgoing saturation, incoming download performance is severely compromised. Look into QoS or "Bandwidth Management".

There are also a bunch of more elaborate load balancing routers at the bottom of the page at:

Another solution is to use a much cheaper WRT54GL and load DD-WRT
