Yes, and no. What you want to do is known as Multi-WAN or multi-homing, and it will allow you to "bond" two 4 Mbps lines into what is effectively an 8 Mbps line. However, there are several caveats:
If this is something you want to play around with, I highly recommend putting several networking cards into an old computer that you're not using, and load up pfSense on it. pfSense offers something on par with most business-grade routers (very much like DD-WRT), but also has excellent multi-WAN support. |
