It simply doesn’t show up in network manager

rfkill list:

0: acer-wireless: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

it doesn’t seem to be switched off

Any help would be gratefully appreciated…[/size]

2

Please check the networking mode ( wicked / networkmanager ) in Yast’s Networksettings. If it’s set to wicked, change it to networkmanager.

3

it’s using networkmanager… but the wifi interface doesn’t show in wicked either… it does work in Windows 8.1

4

Please show output of

lsmod | grep ath

and

ip addr

and, as root

lspci -vvv | grep driver

Does the laptop have a Fn+? button to switch on / off the card?

5

nope , no switch… geen schakelaar

The card works:


3: wlp0s20u4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether f4:ec:38:e6:94:87 brd ff:ff:ff:ff:ff:ff
    inet **192.168.2.2**/24 brd 192.168.2.255 scope global wlp0s20u4

This clearly shows the card has gotten an ip address

Please also show output of


cat /etc/resolv.conf

john@linux-j1e2:~> cat /etc/resolv.conf
# Generated by NetworkManager

It’s more than 6hrs time diff… als ik niet terugschrijf ben ik aan het slaapen, ok?

8

Knurpht, I just realise, that IP address is not from the built in wireless adapter, it’s the usb TPLINK I’m using right now… otherwise I’ve no connection.

Please post:

/sbin/lspci -nnk | grep -iA3 net

or if there is no Wlan output the corresponding

/sbin/lspci -nnk

for Wlan.

I have since discovered that this particular Qualcomm adapter is not yet supported under linux, there are several bug reports about this… for example here: Bug #1484159 “Qualcomm Atheros QCA9377 802.11ac Wireless Network...” : Bugs : linux package : Ubuntu

11

I am on Kernel 4.2 and the Qualcom (168c:0042) is not supported.

thanks, but ugh!:\ another long wait until 4.3 hits Tumbleweed, I see… (sigh)
is there any workaround, apart from using a usb wifi adapter?
