    Hello Team,
    Kudos for creation of the excellent Alpha board!
    I have one minor problem:
    My Alpha 864 connects only 100Mbps and cannot work 1000Mbps on Windows 10 nor on Mac OS Mojave.
    I tried with Unifi Switch as well as different other switches and different cables: cat 5, 5e, 6, without success.
    How to enable the Gigabit speed?

    Problem solved: this was a „cold junction” on Ethernet socket pin 5 and 7 — i.e. bad soldering in the factory.

    @Olgierd001, would u please kindly share more about how did you figure out the problem? Includes some pictures to explain for me. It will be really helpful for me to organize the product to see if we need to extend extra testing on this point when manufacturing! Look forward to your suggestion!
    Enjoy Tinkering with LattePanda ! :lol:
