Sounds promising. Will check after dinner.
If you have a multiport switch or hub, try moving the patch cables to a different port as well. I’ve seen that, too, in addition to bad cables.
One example: Had a client complaining about slow data transfer rates (long story, short on details, not relevant).
Short story: Their IT had installed a single patch cable from the VOIP system for their phones and the hardware adjusted their speeds to 10mbps. Apparently the VOIP cables are crap for anything but phones and have the tiniest print rather than some obvious label identifying them as such.
I should’ve billed the hell out of ‘em. PITA to figure that one out. Keep an open mind or, to keep your sanity, go peer to peer with a long cable and just do the transfer (iirc your prior comment). They also make handy cable kits to connect a hard drive to your other computer. Cable kit is only $30 or so and is universal (IDE or SATA).
But if you need the bandwidth you’ll have to solve the problem.
