@optix:
Is it possible bcs the SW is a little stupid when i change manualy speed interface in pfsense dosent work or problem to be from the cable?
Bcs when i change WAN interface speed to 1 Gps it shows red x.
Your first suspect should be the cables. The switch you're using is a gigabit switch, you should be getting gigabit at least on the LAN. WAN is a different story, the hardware provided by your ISP may only handle 100 Mbps, depending on the speed you're paying for.
Especially suspect the cables if forcing gigabit mode on the LAN interface causes it to disconnect as you're seeing.
If the cables are good, then you might have an issue with the gigabit cards you installed in the box. (The BSD driver might not want them to go into gigabit mode). Unlikely this is the problem, but not impossible.
