Thank you for contacting Intel.
The screenshot attached shows only the chipset and the Wireless connection driver versions. With regards to the drivers, we do not always update the driver of older network card. Even if we provide updated driver package, the driver for these adapters remains at the same version.
The slow upload speed to Europe is due to the limit set by internet providers to discourage home users to push large amount of data. If you wish to have a faster upload speed, please contact your service provider.
As I see it, you don't have any issues with your wired LAN connection since you are able to make fast upload and download within Lithuania.
I hope I was able to address your concerns. Please feel free to contact us again if you need further assistance.
When my ISP support guys came with tablet and checked speed with the same cable, they got 80-90 Mbps to Europe. I get 6 Mpbs, so they say problems are on my side. So I just try to make everything I can on my side.
