we're using the HP elitebook 840 G3's, they have so many issues its unreal, but the main issue that is annoying is the intel LAN is so slow. on the wireless i get 5MB/s download, switch to wired (on the same network) and it struggles to get 100 kb/s. other machines on same network cable get the full 5 mb/s speed. I noticed the driver on the HP website is outdated, so i tried the one from intel, this is also very slow. I have tried through a dock and straight in the LAN port, no difference. this is all with the latest bio's v1.10. chipset etc is up to date. nic setting are auto duplex. I've had issues like this before where going back to a really old driver fixed it, but i cant find any for this device.
very frustrating!!
