@Zogg-Baubas yikes! why the --force flag??

Hey, Administrators, when will you resolve the wifi connectivity issues that we're talking about on this thread?

Zogg Baubas

@Lazar-Demin said in Omega2+ fails to connect to wifi:

@Zogg-Baubas yikes! why the --force flag??

Because without it I'v got the same result. Figured, as this particular Omega was useless in this state, it couldn't get worse even if bricked. In the end '--force' didnt achieve anything that unforced version didnt.

Kostas David

@Zogg-Baubas It seems that we have to find the solution by ourselves, the Admins do not help at all.
Have you tried the new version of firmware?

WereCatf

@Zogg-Baubas I already instructed you in http://community.onion.io/topic/1178/wifi-connection-problem-with-omega2/21 how to flash the image correctly.

xmatt

@Kostas-David - I tried omega2p-v0.1.8-b145.bin and still no luck getting the wi-fi working yet. I'm using a Mikrotik router and I've never had any issues with other devices.

Gerald Schalek

I had also connection problems because i had special characters in my wlan password! After the upgrade of the firmware it also works with special letters!

Kostas David

@xmatt I also confirm that upgrading the firmware didn't help.
@Gerald-Schalek my wlan password does not container special characters but the wifi does not connect

Kostas David

Status update: By installing firmware omega2p-v0.1.8-b145.bin I managed to get connected to my Android phone's mobile hotspot with no security.
Problems:

Omega cannot get connected to Access points with security enabled (WPA, WPA2 etc)
No access to cloud, it is shown as "Offline"
LED is constantly blinking, even after restart
No internet access from the SSH terminal
Sometimes there is internet access from Console (it checks for new firmware successfully.

Still unusable...

Kostas David

Hello, I would like to share my progress. I finally managed to connect Omega2 to my router. The problem was the encryption type. My router uses "TKIP" but Omega2 has "AES".

So, I entered the following:

uci set wireless.@wifi-iface[0].ApCliEncrypType=TKIP
uci commit wireless
etc/init.d/network restart

Note: The firmware I am using is 0.1.7 b139 because for some strange reason the firmware update downloads this version instead of 0.1.8. But it works

Mikaël PIRIO

Hi,

I had the same problem but I solved it. Here's how i did:

connect to your Omega2
list APs with this command: aps

root@Omega-XXXX:~# aps
WRTnode AP scaner.
Begin scaning APs, pls wait...
Finished.
APs available are...
ra0       get_site_survey:
Ch  SSID   BSSID               Security         Signal(%) W-Mode  ExtCH  NT
...
10  MyAP   02:6f:d7:3e:8e:60   WPAPSK/TKIPAES   50        11b/g/n NONE   In
...

This command give you more information about your AP. The most important is Security.

Take this conversion table to modify your /etc/config/wireless config file:

aps:Security            vw:ApCliAuthMode/ApCliEncrypType
=========================================================
WPA1PSKWPA2PSK/TKIPAES	WPA2PSK/AES
WPA2PSK/AES		WPA2PSK/AES
WPA2PSK/TKIP		WPA2PSK/TKIP
WPAPSK/TKIPAES		WPAPSK/TKIP
WPAPSK/AES		WPAPSK/AES
WPAPSK/TKIP		WPAPSK/TKIP
WEP			WEP/WEP

Before edit it, my /etc/config/wireless contained:

config wifi-device 'ra0'
	option type 'ralink'
	option mode '9'
	option channel 'auto'
	option txpower '100'
	option ht '20'
	option country 'US'
	option disabled '0'

config wifi-iface
	option device 'ra0'
	option network 'wlan'
	option mode 'ap'
	option encryption 'psk2'
	option key '12345678'
	option ApCliEncrypType 'TKIP'
	option ApCliSsid 'MyAP'
	option ApCliPassWord 'xxxxxxxx'
	option ssid 'Omega-xxxx'
	option ApCliEnable '1'

config wifi-config
	option ssid 'MyAP'
	option encryption 'WPA1PSK'
	option key 'xxxxxxxx'

With convertion table, i edited it like this:

config wifi-device 'ra0'
	option type 'ralink'
	option mode '9'
	option channel 'auto'
	option txpower '100'
	option ht '20'
	option country 'US'
	option disabled '0'

config wifi-iface
	option device 'ra0'
	option network 'wlan'
	option mode 'ap'
	option encryption 'psk2'
	option key '12345678'
	option ApCliEncrypType 'TKIP'
	option ApCliSsid 'MyAP'
	option ApCliPassWord 'xxxxxxxx'
	option ssid 'Omega-xxxx'
	option ApCliEnable '1'

config wifi-config
	option ssid 'MyAP'
	option encryption 'WPAPSK'
	option key 'xxxxxxxx'

(I modified option encryption 'WPA1PSK' -> option encryption 'WPAPSK' in config wifi-config section)

To finish, restart network:

root@Omega-xxxx:/etc/config# nr

After some time, you can reconnect to your Omega and verify if you have an IP:

root@Omega-xxxx:~# ia
apcli0    Link encap:Ethernet  HWaddr 42:A3:6B:00:BE:3B
          inet addr:192.168.1.16  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::40a3:6bff:fe00:be3b/64 Scope:Link

          RX bytes:74379 (72.6 KiB)  TX bytes:25424 (24.8 KiB)

You can continue with Onion Setup Wizard web interface (http://omega-xxxx.local/) if you want

ps: after network restart, i checked my /etc/config/wireless, and i saw that a new line was added in config wifi-iface section: option ApCliAuthMode 'WPAPSK':

config wifi-device 'ra0'
	option type 'ralink'
	option mode '9'
	option channel 'auto'
	option txpower '100'
	option ht '20'
	option country 'US'
	option disabled '0'

config wifi-iface
	option device 'ra0'
	option network 'wlan'
	option mode 'ap'
	option encryption 'psk2'
	option key '12345678'
	option ApCliEncrypType 'TKIP'
	option ApCliSsid 'MyAP'
	option ApCliPassWord 'xxxxxxxx'
	option ssid 'Omega-xxxx'
	option ApCliEnable '1'
	option ApCliAuthMode 'WPAPSK'

config wifi-config
	option ssid 'MyAP'
	option encryption 'WPAPSK'
	option key 'xxxxxxxx'

Hope this help you.

@Mikaël-PIRIO After trying everything else, only this worked. Thanks for putting in time for this answer.

Lazar Demin

@Mikaël-PIRIO Thanks for finding the issue and posting the guide!
We'll try to fix this in the coming weeks. For now, I've added it to the known issues listing

T Lin

@Mikaël-PIRIO While this worked for me as well, it required me to modify the settings of my wireless network; namely 1) making it 802.11g/n (previously hard-set to 802.11n only), 2) downgrade from AES to using TKIP. WPA or WPA2 doesn't seem to matter. Having to decrease the encryption strength of the network and switching MAC/PHY standard doesn't seem like a good long-term solution.

Some other puzzling observations: my previous router settings (802.11n, WPA2 with AES) works fine with the Omega 1; also, the Omega 2 works fine when connecting to my mobile phone configured as a hotspot with AES. Seems like an odd corner-case with the Omega 2 and certain APs when using AES. I suspect the 4-way handshake never gets completed since my router never receives the DHCP requests, but verifying/debugging this would require doing some wireless packet captures.

I managed to make Omega2 connect my wireless network provided by Mikrotik RB951B and will share my knowledge with you guys. If you find anything wrong, please, correct me.

Here we go:

        option ifname 'eth0'                                                       
        option proto 'dhcp'                                                        
                                                                                   
config interface 'wwan'                                                            
        option proto 'dhcp'

Having changed those 2 configuration files, I restarted the wireless subsystem by wifi and I could read this:

[ 1329.657946] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 1331.436860] wlan0: authenticate with aa:bb:cc:dd:ee:ff
[ 1331.459985] wlan0: send auth to aa:bb:cc:dd:ee:ff (try 1/3)
[ 1331.468056] wlan0: authenticated
[ 1331.475129] wlan0: associate with aa:bb:cc:dd:ee:ff (try 1/3)
[ 1331.486320] wlan0: RX AssocResp from aa:bb:cc:dd:ee:ff (capab=0x401 status=0 aid=5)
[ 1331.494544] wlan0: associated
[ 1331.497749] IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready

Then I verified that I obtained a network address from DHCP service running on Mikrotik:

# ip a s dev wlan0
8: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000
    link/ether aa:bb:cc:dd:ee:ff brd ff:ff:ff:ff:ff:ff
    inet 192.168.88.224/24 brd 192.168.88.255 scope global wlan0
       valid_lft forever preferred_lft forever
    inet6 fe80::42a3:6bff:fec0:85e1/64 scope link 
       valid_lft forever preferred_lft forever

The crucial part was to configure the wireless subsystem to use Client/Station (option mode 'sta') mode. The effect of this setting is following: OpenWRT/LEDE spawns a wpa_supplicant daemon for the configured interface which takes care of authentication and assiciation... See:

$ cat /var/run/wpa_supplicant-wlan0.conf
network={
        scan_ssid=1
        ssid="MyWirelessNetworkSSID"
        key_mgmt=WPA-PSK
        psk="MyWPA2Key!"
        proto=RSN
}

Conclusion

I can now reach my device!

Hi Guys,

let me add my 2 cents..

The way I have solved my wifi issue:

Check if you have issues already solved by the community, like

there isn't any collision going on,
there are no problems with the channels,
or the encryption,
or your router!

wifisetup, and follow the guide
vi /etc/config/wireless
Focus on the ApCli settings in the wifi-iface block! It was not updated in my case and was also disabled (option ApCliEnable '0'). Add or update all the relevant ApCli options manually to your file! Like this:

config wifi-device 'ra0'
        option type 'ralink'
        option mode '9'
        option channel 'auto'
        option txpower '100'
        option ht '20'
        option country 'US'
        option disabled '0'

config wifi-iface
        option device 'ra0'
        option network 'wlan'
        option mode 'ap'
        option encryption 'psk2'
        option key '12345678'
        option ssid 'Omega-XXXX'
        option ApCliSsid 'MyID'
        option ApCliPassWord 'XXXXX'
        option ApCliEncrypType 'AES'
        option ApCliAuthMode 'WPA2PSK'
        option ApCliEnable '1'

config wifi-config
        option ssid 'MyID'
        option encryption 'WPA2PSK'
        option key 'XXXXXX'

wifi
Enjoy your network!

Hope this works for you!

How do I exit out of the config setup? So after I do the changes, how do I exit out of there to enter a new command? Thanks!

Luciano S.

@Michelle-Esponda , i propose to install nano and use this instead.

For now you can check out the manual of vi:
