What is this LAN card at IBUYPOWER?

[rocket1406]

Onboard LAN Network (Gb or 10/100)

Is this okay for Wired CABLE MODEM Internet?

Like is it the same thing as the Intel 10/100 thing?

 

[Lax]

It means it's an onboard LAN card (most likely 100/1000) it will work with any type of ethernet cable you plug into it.
