Hi all!
I'm facing a strange issue with my new laptop. A new lenovo thinkpad s440 with windows 8.1 x64 and latest intel intel proset drivers (17.0.5).
If my laptop is connected to the charger, i can do whatever i want and i see no issues with the intel adapter (didn't test speed, but no connection drops).
If my laptop is running on battery, everytime i use the windows 8.1 shutdown button, next time i power on my laptop the adapter is gone. In the device manager the adapter is reported as: "Windows has stopped this device because it has reported problems (code 43)". If i restart the laptop the adapter is back and connecting to my wireless. If i do a hard shutdown (shift + shutdown button) the adapter also works fine.
It seems there is a big issue with intel wireless-N 7260 adapter with the default shutdown behaviour of windows 8.1. Any solutions for this?
