Dual Nic

[skkler]

just a question out of curiosity couldnt find an answer online. if i buy a PCIe NIC that have more the 1 port, and i plug in say 2 cables from my router will that double my speed or no?

No, not unless you have a network share and a system that supports SMB 3.0 Multichannel (and the device hosting the network share also has multiple ports or has a higher bandwidth single port)

 

You can configure several different ways for the NIC to operate (some requiring a managed switch and other compatible networking devices in order to work). Chances are you're going to be limited by other parts of the network anyway. For internet speeds, it won't make any difference if we assume your PC has a gigabit NIC already (if it's somewhat recent, it will have)

 

EDIT: As for some possible ways to configure it:

 

LACP (or another Link Aggregation protocol) would provide 2Gbps of bandwidth (if we assume each port is 1000 BASE-T), though the maximum bandwidth per session is still limited to 1Gbps. So, you could have two 1Gbps sessions/connections going at once, but not a single 2Gbps connection. Doing this also requires you having a switch that supports LACP (or whatever protocol you use). It's mostly useful for host devices that have multiple devices accessing it at once. Things like a NAS would make good use of LACP (and of course a switch that supports it too) as it would allow multiple devices to utilise full 1Gbps links to the NAS at once. 

 

Failover: Basically, if one port or cable fails, the other will step in as if nothing happened and you won't lose your connection. This can be useful if replacing the cable or port would be difficult. It allows you more time to go about replacing it.

I exceed 1Gbs on file transfers from my file server via Link Aggregation. Not sure what i'm doing different.
