Yeah. Was on fibre a few months ago but moved, and stuck on a (much) slower copper connection. The issue however has been with me since I had fibre, so we're back to square one
Also. Spent 30 minutes carefully prying the NUC's motherboard from the chassis (that was fun...). No visible issues with the antennae within the NUC. Unsure what you meant by 'antenna issue, for both devices', because the laptop using the 5100 card is perfectly fine (and has always been). I'm only suspecting the speed readings to be like that because of a bug in Windows 7 maybe. Anyways.
Wasn't keen that the 17.12 driver is not official (and it's from an unknown source as far as I'm concerned). Have nothing to lose so... Gave it a try by:
- Extracting the Win7 folder that I found inside (hence bypassing the ProSet software)
- Uninstalled the 17.1.0.19 driver
- Restarted the NUC
- Went back to Device Manager
- Right-click, then chose Update Driver
- Pointed the target as the Win7 folder extracted earlier, and that installed 17.12
- Gave the NUC another reboot
First-time connection with the new driver stayed in the 'identifying' stage for a few minutes. Then it sussed itself out, and off I went testing.
So far so good. Have NOT TOUCHED A SINGLE SETTING in Device Manager. I'm streaming 1080 Youtube videos and sweet baby buddha it is not buffering. At all. It's been 20 minutes, and not a single buffer related lag.
So yeah. Looks like it's been a driver issue all along. Going to play with the connection a bit more and see how it fares, but it's looking good. Heck, even put the NUC to sleep and woke it back up 2 minutes later. No issues.
If only Intel officially releases 17.12, then I'm all happy now.
A big thanks for the 17.12 suggestion Gatto, and to anyone else reading, apologies for the constant spammage elsewhere.
