1Gbit nic = 100 Mbit speed negotiated

[FuriousRage]

Hi.

I have a nic that is a GBit one, but it only negotiates 100 mbit.

This network card is connected to internet, that have 250/100 Mbit speed. no router or switches between the nic and internet. Any ideas how to get it to set Gbit?
I have tried ethtool -s eth1 speed 1000 autoneg off. But then i cannot get a link at all and ethtool eth1 says unknown on speed.

I'd double check that the internet device, modem I'd assume, has a gig nic. I've ran into a few areas where they buy 100+ speed, but have a 10/100 nic facing in..

No modem.. FIOS connection.
Check all cables. they are either Cat 5e or Cat6.


EDIT: I changed cables from internet to server to a Cat6 labeled cable.. i can now ethtool -s eth1 speed 1000 duplex full autoneg on but i STILL only get 100Mbit
tomorrow i will swing by my work and fetch my work laptop and test its ethernet port directly to internet and see if speedtest still says 100mbit..

No other ideas why i keep getting 100mbit only when all stuff here has Gbit speeds?
