Further to #27 - So much for resolution. Browser speed is still terrific since switching to 5e cables, but I'd forgotten I'd disabled the HD Audio in the BIOS very early on in the hunt for a solution to the ethernet speed problem. A couple of hours ago I noticed no sound and re-enabled the HD Audio only to receive the same dismal ethernet speeds reported earlier. Disable the HD Audio in the BIOS, and ethernet performs like a champ. HD Audio was disabled through most of the adventures I had this past weekend so I still thing there's something to the 5e cabling. Sorry if this misled anyone.
