Seting up a Wifi-network hosted from my laptop

Hello all,

I'm trying to setup a wifi-network from my laptop, so other devices can log on to my wifi and be on the same lan.
However, i tried googling how to do this with netcfg mut i keep getting results about just seting up a normal wifi-connection to a router.
Any ideas?

tanx,

Joran

Welcome to the forum, jorants.

Double-check first that your wifi card supports wlan "master mode", which a lot don't. Searching the forum for "hostapd" will lead you also to relevant results.

Re: Seting up a Wifi-network hosted from my laptop

Hey,

tanx for the reply.
i get the follow output from lspci  -v:

02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
        Subsystem: AzureWave AW-NE785 / AW-NE785H 802.11bgn Wireless Full or Half-size Mini PCIe Card
        Flags: bus master, fast devsel, latency 0, IRQ 17
        Memory at dea00000 (64-bit, non-prefetchable) [size=64K]
        Capabilities: <access denied>
        Kernel driver in use: ath9k

and the ath9k driver supports AP mode. also, i have made a acces point in windows some time ago so the card sould also suppot it.
however i get an error when itry to start hostapd.
systemctl status hostapd gives:

Re: Seting up a Wifi-network hosted from my laptop

With respect to the listed error re-check the output of

 iw list |grep modes -A 8

If "master" mode is listed: There appears to be some problem with the recent hostapd that may be causing your issue. Have a look here:
