Hi,

I put psk on file /et/wpa_supplicant.conf inside quotation marks and now error message is different. I also recreated file with wpa_passphrase.

Current error message is:

My WLAN device is Apple's Airport Extreme and wireless type WPA Personal. I don't want to change password on Airport since it would require changing password to each device on my network and for example changing password for my printer is task that i don't want to do "if it works, don't touch it"

EDIT: I fired up temporary WLAN with name 'TANA' and password '12345678' and configuration file looks now:

Hi,

Managed to fix problems related to wifi, OPI+ connects now to my WPA2-PSK WLAN on boot automatically.

Solution is not very sophisticated but works and that's most important thing for me.

Current status of configuration files:
/etc/wpa_supplicant.conf:

1. 
   
2. ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
   
3. update_config=1
   
4. 
   
5. network={
   
6.     ssid="mySSID"
   
7.     proto=RSN
   
8.     key_mgmt=WPA-PSK
   
9.     pairwise=CCMP TKIP
   
10.     group=CCMP TKIP
    
11.     psk="Password_on_PLAIN_text"
    
12. }
    

Copy code

/etc/network/interfaces :

1. 
   
2. # interfaces(5) file used by ifup(8) and ifdown(8)
   
3. auto lo
   
4. iface lo inet loopback
   
5. 
   
6. # allow-hotplug wlan0
   
7. iface wlan0 inet manual
   
8. wpa-roam /etc/wpa_supplicant.conf
   
9. iface default net dhcp
   

Copy code

And added following lines to /etc/rc.local

1. 
   
2. /sbin/ifconfig  wlan0 down
   
3. /sbin/ifconfig  wlan1 down
   
4. /sbin/ifconfig  wlan0 up
   
5. /sbin/dhclient wlan0
   

Copy code

Tested by booting several times, survives also if only networking is restarted.

Well, wifi works ONLY if wired is connected...more troubleshooting,,

Is this not just the 'usual' default route problem?
The default route pointing to the Ethernet interface and therefore preventing access to the outside when no cable is connected. Have seen this a few times and could be solved by using if-up/if-down scripts adjusting the default route accordingly.

miha

Hi,

Yes, i believe that this is the default GW issue. Figuring out how to handle situation.

Well, I'll take some distance to this. I had same problems with cubietruck and then i decided to plug LAN-cable and forgot crappy combination Linux&WLAN.
I'll keep trying with OPI+ but break is now needed.

-miha
EDIT: Yep, definetely routing issue. ssh to wlan ip work inside OPI+ but not from outside and I haven't figured out how to solve this.

Flushed all from routing table with  #ip route flush table main

Now I would like to set gw-setting like on my cubietruck:

1. 
   
2. miha@ct ~ $ route -n
   
3. Kernel IP routing table
   
4. Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
   
5. 0.0.0.0         192.168.255.1   0.0.0.0         UG    0      0        0 eth0
   
6. 192.168.255.0   0.0.0.0         255.255.255.0   U     0      0        0 eth0
   
7. miha@ct ~ $
   

Copy code

But wlan0 instead of eth0. Second line is quite easy, #ip route add 192.168.255.0/24 wlan0 gives almost same line but G is missing from Flags and my brains are frozen to solve this and how to get first line.

miha

Hi,

I have now played lot of with my OPI+, managed to cut all connections in and out but that is fixed with magic ip route-command

Currently ssh in and out works directly after boot IF lan-cable is connected.

Does not respond to ping, I can see from above that default needs to be changed somehow. I am not very familiar with routing commands...

Well....

SSH in via wlan0 works now, even when eth0 is unplugged.

Status of routing is:

1. 
   
2. root@tiger:~# ip route show
   
3. default via 192.168.255.1 dev wlan0
   
4. 192.168.255.0/24 dev wlan0  scope link
   
5. root@tiger:~#
   

Copy code

These commands brings wlan0 alive:

1. 
   
2. root@tiger:~# ip route del 0/0
   
3. root@tiger:~# ip route del 192.168.255.0/24 dev eth0
   
4. root@tiger:~# ip route add default via 192.168.255.1
   
5. root@tiger:~# ip route show
   
6. default via 192.168.255.1 dev wlan0
   
7. 192.168.255.0/24 dev wlan0  proto kernel  scope link  src 192.168.255.7
   
8. root@tiger:~#
   
9. root@tiger:~#
   
10. root@tiger:~#
    

Copy code

Now i need to implement commands to boot up procedure.
Br
-miha

EDITirty but working solution; added following to /etc/rc.local

1. 
   
2. /sbin/ip route del 0/0
   
3. /sbin/ip route del 192.168.255.0/24 dev eth0
   
4. /sbin/ip route add default via 192.168.255.1
   

Copy code

I know that correct place is not rc.local, instead of that post-up command(s) should be used on file /etc/network/interfaces since rc.local will be executed  only on boot, so correction is needed for this still.
Also, eth0 is not usable at the moment but that's not an issue since place where I am going to locate OPI+ has no LAN (RJ45) available.
