orkneywool,

Your SSID is case sensitive and there are a few illegal characters for SSID too.
It claims it can't match your SSID.

A problem waiting to happen is
Code:
psk="1234567890"

With the quotes, its a string that will be applied to the string to hex converter before its used for your key.
Without the quotes, its treated an a hex number to be used directly.

Both psk="1234567890" and psk=1234567890 are correct syntax but they are different keys.

Line 7: Invalid PSK '86abcfe876'.
A valid psk key needs 64 hexa digits or a string (double quoted) from 8 to 63 ASCII characters. Your current key is only 10 hexa characters.

orkneywool ... how did you aquire/generate the psk? The above isn't a 'psk', its a "word".

wpa_passphrase BTHub4-SRJS 86abcfe876:
network={
  ssid="BTHub4-SRJS"
  #psk="86abcfe876"
  psk=f49a99ab6a6e14e93573f0cb7bab08845684468b0c19cf26adfa54ab347e212e
}

As for your initial "SSID mismatch", this could be caused by a number of things, most likely another 'VAP' (virtual AP) with the same SSID. You could supply the BSSID which hopefully will avoid the issue:

Code:
network={
  ssid="BTHub4-SRJS"
  bssid=2C:39:96:B6:FB:86
  psk=f49a99ab6a6e14e93573f0cb7bab08845684468b0c19cf26adfa54ab347e212e
  scan_ssid=0
}

If the above fails then please supply (via pastebin) the full wpa_supplicant.log, and the output of

Code:
# awk '{RS="Cell"}/BTHub4-SRJS/' <(iwlist dev wlp1s6 scan)

Also, note in the above you've provided '-iwlan0' and '-iwlp1s6', and used '-Dnl80211' and '-Dwext' ... that can't be right, at least for the interface name, so consistancy. Your interface probably is 'wlp1s6', and should be using '-Dnl80211'.

best ... khay

orkneywool,

psk=86abcfe876 is a hex number, to be used as the psk directly.
psk="86abcfe876" is a text string to be converted to hex before its used as the key.

The quotes matter. If your Access Point uses a pass phrase, use the same pass phrase here - in quotes.
If it uses a hex key, most don't, use it here but no quotes.

Its double quotes.

the relevant ( i think) output of iwlist wlp1s6 scan is here http://pastebin.com/a33MLaUM

the BT Home hubs come with a 10digit key , not a passphrase
ive generated a wpa_supplicant.conf file with wpa_passphrase
the attempt at connection is here

orkneywool ... that sounds like a wep key (generally 10 digit), or WPS key (though wps is eight digit, not ten). Anyhow, from the scan I can't tell if wps is in use (as iwlist doesn't show extended capabilities), and wep doesn't seem to be available.

orkneywool wrote:
[...] the attempt at connection is here

That shows 'ap_scan=0' ... which shouldn't be the case (as that is for 802.11x for wired networks) ... I suspect that is why we see "could not read SSID from driver" subsequently.

Besides the psk the following should be correct:

/etc/wpa_supplicant/wpa_supplicant.conf:
ctrl_interface=DIR=/run/wpa_supplicant GROUP=wheel
update_config=1
ap_scan=1

network={
  ssid="BTHub4-SRJS"
  bssid=2C:39:96:B6:FB:86
  scan_freq=2462
  scan_ssid=0
  proto=WPA2
  auth_alg=OPEN
  key_mgmt=WPA-PSK
  group=TKIP
  pairwise=CCMP
  psk=
}

If this fails then it should be due to authentication ... and we then know the psk provided is incorrect.

Code:
Dec 31 17:18:24 mars kernel: [   46.445578] wlan0: authenticate with 2c:39:96:b6:fb:86
Dec 31 17:18:24 mars kernel: [   46.558580] wlan0: send auth to 2c:39:96:b6:fb:86 (try 1/3)

Dec 31 17:18:24 mars kernel: [   46.564691] wlan0: associated


That's the hard bit done. With the wireless stuff out of the way, it can get an IP, if you ask it to.
Try
Code:
dhcpcd wlan0
Give it 20 sec or so and look in
Code:
ifconfig -a

orkneywool,

The SSID of your AP is BTHub4-SJRS
and your wpa_supplicant.conf contains BTHub4-SRJS.
