DLink DSL 2750B. Add this router to the incompatible devices.
I've the reported issues neverthelesse I've applied all the suggested corrections and update the driver.
Intel N7260 continously drop the connection and it seems connected but it cannot surf the Internet neither has access to the LAN (i.e. admin interface of the router).
Lenovo E540 with Windows 8.1 updated to the last patch!
It' really annoying that in 2014 we should yet face us with wifi connection issues!!!!
