2 net connections to 1 router?

Are there any routers or other devices which would take 2 incoming cable internet connections and send data over both connections at the same time?

edit: ok. found some info on routers with dual wan ports that talk about load balancing. would this load balancing happen on a per file stream or on a per pc basis. meaning would 1 pc sending 2 files at the same time utilize both outgoing internet connections through the router?

Load balancing is achieved my monitoring activity.

Example: Let say one pc1 is doing a large download, the other is general web surfing. What happens is that it will see pc1 using WAN1, So it will roll pc2 over to the other line. Now be careful with BT, It's possiable for it to tie up both connections.

You can send multiple files at the agregate bandwidth, Single files will come down and go up at the single connection rate.

Channel bonding is what you are looking for to speed up a single file's rate.

I don't think you'll find any routers that support this feature.

From what I have read, the linux solution would require a similar solution at both ends, i.e. your ISP would have to have a linux box that supported the feature. The last time I saw channel bonding as a service provided by an ISP was when 56K modems were all the rage.

To my knowledge, the dual WAN routers only are a benefit when there are multiple users and files in flight. If it helps, most web pages are made up of many files, nowdays mostly image files.

For large single file uploads your out of luck. Unless... Bittorrent or similar would be a viable mechanism for breaking up a large file into pieces and sending it over multiple connections.

This might be an option - there are others at the same price point. Cisco Linksys RV042 10/100 4-Port VPN Router
