Got upgraded from Lightspeed 100g to Warpspeed 100g today and got a new Cisco DocSis 3.0 modem put in, the techie said The "link" light on the modem panel, should be green, its yellow flashing, the other 4 lights are green then said something about I might not have a 1gb eternet port on my laptop, then did a speed test and looked fine speedwise, how do I know if i have this 1gb eternet port on my laptop? it's a toshiba satellite L640 laptop, does anyone else have a yellow flashing "link" light or is yours green?.. thanks =)
