At 90m, you're pretty much at the max for Cat5/6 cable length; maybe your cable is marginal?

It sounds like you've already tested the Z68 with shorter cables and the problem only shows up when you exceed about 60m. If that's the case then the problem would appear to be either: 1) your particular MB is defective, or 2) the Broadcom chipset can't support longer cable lengths.

You could:
Try another cable,
Try a quality PCI-e lan card with, say, an Intel or NEC chipset (not sure which is better),
Go wireless,
Get a replacement Z68-pro3 MB
Choose a completely different MB

Good luck.

Dear mmels,

We use 100 meters LAN cable to do the test with Z68 Pro3 and lan can work normally.

Please kindly reinstall the lan driver from below link to try.

Or please kindly change another lan cable to try.

Thanks!

Have a nice day
