Question Slackware 14.1 and Intel 7265 Wireless A/C Wpa_supplicant problems


I have been trying to solve these problems now for three days - much to my annoyance, I have never had so many problems configuring wireless for Linux before.

My router is a AVM Fritzbox 7490, it features separate 2.4Ghz and 5Ghz radios and is an AC1200 rated router. Both radio interfaces have the same name and their Mac Addresses differ by one digit - primarily the last one, both interfaces use WPA Encryption in WPA2 CCMP mode.

The Fritzboxs IP is 192.168.1.1 - a pretty basic class C network address and I have no problems connecting to this under Windows 10.

I have configured /etc/wpa_supplicant.conf and /etc/rc.d/rc.inet1.conf and I get a message saying that wpa_supplicant ran successfully when I boot ; however running wpa_cli gives the following results.
<3>WPS-AP-AVAILABLE
<3>CTRL-EVENT-NOT-FOUND
...... Rinse and repeat.

-- /etc/wpa_supplicant.conf --
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=root
network={
scan_ssid=0
ssid="name of my router assigned to both interfaces which is FBX-7490"
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk="s:my stringy password"
}

-- /etc/rc.d/rc.inet1.conf --
GATEWAY="192.168.1.1"
IFNAME[4]="wlan0"
IPADDR[4]="192.168.1.153"
NETMASK[4]="255.255.255.0"
USE_DHCP[4]="no"
WLAN_ESSID[4]="The SSID name you gave your router"
WLAN_MODE[4]=Managed
WLAN_CHANNEL[4]="auto"
WLAN_WPA="wpa_supplicant"

O.K After a lot of searching I have found what the problem is and the following is how to fix it.

The intel 7265AC wireless card includes a p2p mode which if I understand correctly from what I was reading allows the device to connect via a point to point interface to negotiate connections regardless of if it is to the controlling router - or a connection between two machines connected to the router < note everything after the - is supposition and I have not tried it yet.

Installing Slackware 14.2 Beta 1 - Do NOT set up a network or allow NetworkManager to set things up.

Follow instructions found here https://wiki.archlinux.org/index.php/WPA_supplicant starting from overview - read these very carefully there are still a couple of pitfalls which if you do read carefully you will solve.

Note I use fixed IP so after the save_config I edited /etc/rc.d/rc.inet1.conf by hand and filled in /etc/resolv.conf by hand. After performing the rest of the instructions I rebooted and was immediately able to ping my router once I had logged in..

NB:
1) This setup will allow you to access your wireless from a shell / and/or X but under X you will have no interface to tell you whats going on.

2) If you run NetworkManager at this point you will BLITZ the config and have to start from scratch - so don't do it, I don't know about wicd as I have not tried it yet. I am also yet to try turning off and on my lappys wireless with Fn + F12 - so that may not work either.

3) If you have two wireless radios one at 2.4G and one at 5G this will still work and you will get the full speed out of it, on my system I am presently getting 867Mbps out of it.

Good luck to anyone else having the same problem - if I sort the X display of wireless stats ill add that to this.

Cheers.
