I tried to download from intels homepage the official wi fi driver and from samsungs homepage.
and i did not succed i cant connect any wifi on the laptop.
I hope someone can help me already tried:
Intel® Centrino® Advanced-N 6235 drivers and they are not working :-(
I really would like the Wifi on my computer working
Normally windows 8.1 and windows 8 have the wifi set by default no needs for driver . but this time i need it. hope you can help me.
I am sorry for your issue.
At first I would like to suggest this two steps verification:
It is also possible that the device appears as "unknown device" or simply "network adapter" because the driver is missing. It could really help connecting via wired Ethernet in order to install the Intel® driver with the http://www.intel.com/p/en_US/support/detect?iid=dc_iduu Intel® Driver Update Utility or even let Windows* install its inbox driver via Windows* Updates.
Based on your description I believe this is more of a software issue because of the fresh operating system install, right? Therefore you may consider using the Windows* version provided by the system manufacturer (OEM) instead of a retail version. However, you may need to contact the system manufacturer for assistance in case the wireless adapter does not appear at all after the recommendations presented above.
