Unhappy I can't connect to network in Scientific linux 6.9


I installed scientific linux 6.9(based on redhat 6 ) on my surface book but it doesn't connect to my wireless network . When I open system preferences + network , it doesn't find any existing wireless and when I manually add a new network connection, it never connects to it . What should I do ?

I searched and tried alot of approches but non of them work for me .
thanks for your help

Then you don't have a device driver for the network installed yet. Do you know what wifi chip you have? Find out, then figure out its device driver, then load that device driver with modprobe.

If it's built-in, lspci; if it's USB, lsusb.

i think it's this :
[root@localhost fatemeh]# lspci | grep -i wireless
03:00.0 Ethernet controller: Marvell Technology Group Ltd. 88W8897 [AVASTAR] 802.11ac Wireless
but now how can i load that device driver with modprobe?

Does it need a driver? Or just a network configuration? I'm not sure...

Inspect drivers/net/wireless/marvell in the kernel source. This chip is in the mwifiex subdirectory. Its README identifies its driver as mwifiex, so
Code:
modprobe mwifiex

/usr/src/linux-$version . You don't need to know where it is. Does
Code:
 modprobe mwifiex
work? If it does, do you see a new device in /proc/net/dev ?

Then you lack mwifiex.ko, the driver needed to use your wifi. Does
Code:
locate mwifiex.ko
find it?
Code:
locate mwifiex
find anything? It's in the kernel of my distribution; I'd guess it would be in the kernel of any distribution, but I don't know about yours.

Both of them don't have any output. I think the main reason is as mentioned here https://scientificlinuxforum.org/ind...t=0#entry21304 . I think I should upgrade my kernel but without having any network I don't know how to do it?

You download the kernel package(s) from its host then install it(them). I don't see a forum for Scientific Linux on this site; perhaps its own fora have better support.
