My two mobos will not show full 1.0 gbps speed in local area connection. I have set both to full 1.0gbps duplex speed ,but they only show 100.0mbps. My p45ud3r used to show 1.0gbps speed but doesnt now for some reason.My second mobo is p45tusb3p it too is set at 1.0gbps full duplex ,but reads at 100.0mbps.At this time I am experiencing bad internet connections, could my router be causing this problem?
