Nanopi WIFI settings

Forum: Linux
Naveen 
I am unable to setup wifi with NANO pi . 

I  have used the below as per your literature:

auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet dhcp
wpa-driver wext
wpa-ssid <MYSSID>
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk <MYWIFI PASSWORD>

Still unable to connect to our local Wi-Fi. I have changed the security
settings to WPA2-PSK in the above to suit our Router which is configured
with WPA2-PSK security settings. The Access point SSID and Password are
checked several times.

Does this module work only for WPA-PSK ? or any other security schemes ?


I am to scan and see the wifi networks, but not able to connect. any help
is appreciated 

Thanks
Naveen

This is the process I will be using when my NanoPi arrives.

After a quick look through I don't see anything different, but do post back
if you sort it.

Good luck,
Dave

Looks like this document was just updated with some WiFi information.

Worked when I disable AP mode.

I can not see my nanopi WiFi AP. I use command 'turn-wifi-into-apmode yes'
but nothing changed. Is there any other initialization for WiFi?

Thanks,
Arash

Arash 
I think problem is because of driver. Here is output of execution of
hostapd manually:

root@nanopi:~# hostapd /etc/hostapd/hostapd.conf 
Configuration file: /etc/hostapd/hostapd.conf
nl80211: Could not configure driver mode
nl80211 driver initialization failed.
hostapd_free_hapd_data: Interface wlan0 wasn't started

How can I fix this?

Regard,
Arash

how to disable the AP mode ??? followed the wiki link but bot much success
... please help which link you were following @Naveen

Phil_in_China 
You could try:
turn-wifi-into-apmode no

Kit 
Nope .. nothing happened ...i want to run internet on my nanoPi .. and cant
configure wifi settings ?????

davef 
turn-wifi-into-apmode no

I also set a static address in wlan0 and I get:

root@nanopi:~# hostapd /etc/hostapd/hostapd.conf 
Configuration file: /etc/hostapd/hostapd.conf
Using interface wlano with hwaddr 04:e6:76:71:49:77 and ssid
"nanopi-wifiap"
wlan0: interface state UNINITIALIZED->ENABLED
wlan0: AP-ENABLED

Seems odd that cat /sys/module/bcmdhd/parameters/op-mode says 0 and the
above says AP-ENABLED

Hi Dave

I used wpa-cli commands, see http://nanopi.org/NanoPi_Quick%20Start.html 

for some suggestions. I did manage to get my nanopi connected to the net.

davef 
Thank you.

davef 
OK, I see there are few extra sections in that document.

wpa_cli -iwlan0 scan
OK

wpa_cli -iwlan0 scan_result
bssid              freq  signal level  flags            ssid
1c:af:05:39:1a:93  2437      -59       [WPA2-PSK-CCMP]  [ESS]AndroidAP8362

There is no /usr/sbin/wpa_action to edit.

I changed the sample wlan0 file:

auto lo
iface lo inet loopback

auto wlan0
iface wlan0 inet static
address 192.168.43.10
netmask 255.255.255.0
broadcast 192.168.43.255
gateway 192.168.43.1 (my WiFi Hotspot)

wpa-driver wext
wpa-ssid YourWiFiESSID
wpa-ap-scan 1
wpa-proto RSN
wpa-pairwise CCMP
wpa-group CCMP
wpa-key-mgmt WPA-PSK
wpa-psk YourWiFiPassword

The command route seems to indicate that the NanoPi has found the Hotspot.
And ifconfig -a shows the correct information.

I am also puzzled why lsusb shows nothing and dmesg | tail does not look
anything like the example in the guides.

Ugh.  Make sure you are using a USB data cable not a USB power only cable
:(

Hi all,

Last night, I've been successfully connected to Android AP Tethering mode
by using wifi mode on NanoPI, I'm using OpenWrt Chaos Calmer 15.05 as a
root file system, and connect to AP with some wireless tools package (not
default luci wifi tools)...

But still at my thinking that it seems to be has a driver problem,
since i keep got erorr authentication while connecting to my TP-LINK AP...

I will post some connection steps and logs that probably could be solved at
this forum...

Is the signal level getting marginal?  Later on -91dBm, I am surprised that
it is still working.

Can you get closer to the TP-Link and see if your command:
root@OpenWrt:~# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf
works successfully?

=================================

---------------------------------

I'm not sure that's accurate, coz I place my devices near me (not far than
1 meter)

=================================

---------------------------------

Yeah, I'm curious too, since TP-Link use mixed method:
Encryption: mixed WPA/WPA2 PSK (TKIP, CCMP)
will post another logs soon...

=================================
192.168.3.1  Are you setting your own usb0 IP address, mine is
192.168.100.1
---------------------------------

Yes, I configured it my self on WebLuci of OpenWrt,
seems everything configurable on Luci, except of the wifi, it's not
detected automatically by Luci, so I should manual wifi connection
instead...

Btw, I'm using rootfs taken from
openwrt-15.05-kirkwood-generic-rootfs.tar.gz, which was available here:
http://downloads.openwrt.org/chaos_calmer/15.05/kirkwood/generic/
and installed some wifi tools from its distribution packages...

davef 
Finally got the NanoPi to find my Smartphone's HotSpot, so now have access
to the internet.

   turn-wifi-into-apmode no

And put in the suggested wlan0 file at /etc/network/interfaces.d/

When I did /etc/init.d/networking restart I looked at all the messages I
saw on the UART and at the top there was a suggestion:
 
   systemctl daemon-reload

So, I dropped that in on the command line and after that finished I did
another /etc/init.d/networking restart

Saw the same suggestion again, but this time when I pinged 8.8.8.8 it
worked.

Work for anyone else?
