2 ISP connect to 1 pc?

Solution
you would need load balancing capability's on your router. That's not a home router type of thing, we are talking a CISCO router for businesses the cost of the hardware is high and the licensing is even higher.

so in other words just stick with one ISP and upgrade your bandwidth
 
Someone explained this exactly well: is like your multi-core cpu. A single session will not be able to immediately increase its bandwidth. Say you start downloading a big file, performance won't increase, but if you are downloading a bunch of files and your downloader is able to spawn multiple sessions for the download then indeed the TOTAL bandwidth is gonna increase.
 
your net use is based on session. so when you perform a single task it HAS to go out 1 ISP it cannot span both. most firewalls now days are "State aware" so when you start the conversation with a server it expects the traffic from that one ISP (ip address, source port) so if say you are playing a game and it gets fragments of data from 2 ip address and 2 source ports it drops them on the floor. SO! long story short, YES you have more bandwidth while you are multitasking, a single task however will not be faster.
 

Actually there is a way to combine both ISPs into "one" connection. But it requires a significant amount of setup on the router on your end, and a remote server or VPS as the other end. Your router breaks up your network data stream into different chunks, sends them to the remote server over your 2 (or more) ISPs, and the remote server combines them. The remote server acts like a VPN and pretends it's the source of the network data. You will be charged bandwidth on the remote server for both incoming (from you to the server) and outgoing data (from the server to the website). So you're effectively paying for every packet you send/receive 3x. But if your only options are multiple slow Internet connections, sometimes this is the only way to get decent speed.

It's called bonding, and isn't cheap. Though theoretically you could do it all by yourself if you're well-versed enough with Linux and network setup to piece it together with a server at your end and a VPS at the other.

That sounds really good until you read the fine print. If the latencies are even slightly different you get packet out of order. This is interpreted by the end device as packet loss and causes re transmissions. It can lead to session drops and resets. You are in trading one problem for another.

Many of these companies pretend this problem does not exist but you get nowhere near the combined bandwidth in many cases Very technically you are using more but a lot of it is being used for garbage data. This does not include all the overhead for the vpn plus the extra latency to go to the VPN data centers.

Now they can to a point fix this by using software that reorders the data but this causes the connection with the lower latency to have to wait on the faster. This takes a lot of resources so you do not see any of these services offering it.
