networking - Can I combine two Internet connections into one PC using only a switch?

Suppose I have two ISPs (Broadband) with two routers (DSL). Now I have one switch of say four ports.

Is it possible to connect to both ISPs to one PC and combine the two to achieve faster speeds?

Example:

• ISP A gives me a speed of 2Mbps


• ISP B gives me a speed of 1Mbps

Can I connect to both the ISPs at once to get a total speed of 3Mbps?

Is this possible, or will it show me some type of error? I suspect it will say that the default gateway can't be the same.
