Hello All,
I've just installed Centos7 on this laptop, with Mate desktop.
I'm trying to make wireless work with either of these wireless cards:
Intel Corporation Centrino Advanced-N 6235 or
Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)
The N 6235 is the card I'm using for a while on all Linux laptops in our organisation. But I must admit until now we have few I5 machines.
The N6205 is mentioned here as working:
http://www.linlap.com/dell_latitude_e6320
Info on the cpu of the machine:
product: Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz
vendor: Intel Corp.
physical id: 1
bus info: cpu@0
capacity: 3200MHz
width: 64 bits
While I'm writing this, I just reinstalled Centos7 on another type of laptop:
Latitude E6500
wireless card : Intel Corporation WiFi Link 5100 AGN
On the 2 machines with these 3 types of network cards, lspci -v
shows the cards, with kernel module iwlwifi as I would expect:

But when clicking the nm icon in the top right corner, it shows no wireless connections.
[root@localhost ~]# nmcli r

It looks to me like NetworkManager is not managing wireless.
How could I solve this?
Many thanks for any advise.
greetings, Johan
