I just had 5Gb google fiber installed (up from ATT 2Gb/s) and I have an intel X540T2 10Gb/e card for the fiber jack ethernet port. I am NOT using their router/modem. I’m using bring your own router. I have 10Gb/s SFP+ to my switch stack and primary servers.
No link light. on the X540. I went back to my 2.5Gb/s card (QNAP QXG-2G1T-I225) and everything works fine (except my speed is limited). What card do I need to get for the WAN side?
I appreciate any help.
