I've got two PC's wired to two XT8's, and they do wireless file transfers at 110 MB/s sustained, which is the limit of the Gb card in one of the machines. My new PC has a 2.5 Gbps card, and naturally I'm wondering if these XT8's can achieve it. I have to wire the one by the cable modem to a yellow port on the XT8, which I think might stop me in my tracks. Whatever the answer, I'm highly impressed by the performance I'm currently getting.
