Unable to connect to wifi on Linux Slackware 14.2

purnish_dave · 03-05-2018, 02:54 AM

Here's the relevant part of my /etc/rc.d/rc.inet1.conf file

Code:

## Example config information for wlan0.  Uncomment the lines you need and fill
## in your info.  (You may not need all of these for your wireless network)
IFNAME[4]="wlan0"
IPADDR[4]=""
NETMASK[4]=""
USE_DHCP[4]="yes"
#DHCP_HOSTNAME[4]="icculus-wireless"
#DHCP_KEEPRESOLV[4]="yes"
#DHCP_KEEPNTP[4]="yes"
#DHCP_KEEPGW[4]="yes"
#DHCP_IPADDR[4]=""
WLAN_ESSID[4]=SPECTRANET1
#WLAN_MODE[4]=Managed
##WLAN_RATE[4]="54M auto"
##WLAN_CHANNEL[4]="auto"
WLAN_KEY[4]="bf244519cce428111072bff11e4f70affa9e0fb08a8b400e1392d8b5663a71bf"
##WLAN_IWPRIV[4]="set AuthMode=WPAPSK | set EncrypType=TKIP | set WPAPSK=96389dc66eaf7e6efd5b5523ae43c7925ff4df2f8b7099495192d44a774fda16"
WLAN_WPA[4]="wpa_supplicant"
#WLAN_WPADRIVER[4]="ndiswrapper"

Here's my /etc/wpa_supplicant.conf file

Code:

# /etc/wpa_supplicant.conf
# ========================
# This line enables the use of wpa_cli which is used by rc.wireless
# if possible (to check for successful association)
ctrl_interface=/var/run/wpa_supplicant
# By default, only root (group 0) may use wpa_cli
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1
#country=US

# WPA protected network, supply your own ESSID and WPAPSK here:
network={
        ssid="myessid"
        #psk="passphrase"
        psk=blaskdjflskdjflsakdjf.. etc..
}

I cannot connect manually either.

I am entering the following commands.

Code:

iwconfig wlan0 essid myessid
ifconfig wlan0 192.168.1.5 netmask 255.255.255.0
route add -net default gw 192.168.1.1
wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf

On this final command I get

Code:

wlan0: SME: Trying to authenticate with 48:ee:0c:45:28:aa (SSID='SPECTRANET1' freq=2457 MHz)
wlan0: Trying to associate with 48:ee:0c:45:28:aa (SSID='SPECTRANET1' freq=2457 MHz)
wlan0: Associated with 48:ee:0c:45:28:aa
wlan0: WPA: Key negotiation completed with 48:ee:0c:45:28:aa [PTK=CCMP GTK=TKIP]
wlan0: CTRL-EVENT-CONNECTED - Connection to 48:ee:0c:45:28:aa completed [id=0 id_str=]

and then it just gives no further output and doesn't return to the prompt.

Can someone diagnose this.Thanks.

What is the make/model of the computer and what wireless chipset is installed? The command lspci issued in a terminal should reveal that information; you may have to issue the command as root.

Please surround the output of any commands with "code" tags, which become available when you click the "Go Advanced" button beneath the compose post window.

i can't check my setup right at the moment but ...

# WPA protected network

make sure your card and the wifi hub support (and agree) on the authentication method your attempting to use (ie, pks)

log into your modem (ie, 192.100.0.1) and make sure you have your codes right, and do wonder if they are enabled and if they are "case sensitive". try a simple network name without spaces so you don't have such issues.

my issue, after reading directions, ended up just being syntax of my labels

I always use network-manager to configure wifi. You adapter may not be configured at all. Try 'rfkill list' or so to check.

Well, the relevant part of output of lspci is the following.

Code:

02:00.0 Network controller: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01)

I believe the driver is also installed. In my KDE environment I can also see the nearby networks but I am unable to connect to them.

How do you test your connection? Maybe it's dns issue, what do you have in /etc/resolv.conf?

If you want to try Network manager, the easy way is to run ' netconfig ' as root and choose NetworkManager at CONFIGURATION TYPE page

Thanks.

My resolv.conf is the following

Code:

# Generated by dhcpcd from wlan0.dhcp
# /etc/resolv.conf.head can replace this line
nameserver 192.168.0.1
# /etc/resolv.conf.tail can replace this line

However, I finally managed to get my wifi running with wicd. It's a workaround I know.
