Interesting. The Jessie box is using wired LAN via an onboard (ie part of the motherboard) ethernet controller (motherboard is an ASUS P6T iirc). I wouldn't expect it to need firmware, would I be wrong? At the laptop end, it's running Windows 8.1 so gawd alone knows what can / should be updated... Mark
