Linux Kernel 4.9 and a (not so) happy Jornada 720

Hi,

Just to make sure I am doing it correctly.....

In the wpa_supplicant.conf file:

Do I put quote marks around the ssid name or not?

Also put quote marks around the psk password or not?


Thanks,

Mark

Hi Mark!
Yes, with quote marks!

Regards
Stefan

Thanks for confirming, Stefan!

Meanwhile, at work now, so, trying to get connected to guest network using the 'unencryptwifi.sh' script.

And getting a bit confused as what to do to get WiFi working/connected....


First checked with:

 
# iwconfig 

lo             no wireless extensions 

 

wlan 1      no wireless extensions 

 

dummy0   no wireless extensions 

Then

 

# ifconfig 

dummy0:  flags=195<UP, BROADCAST, RUNNING, NOARP> mtu 1500 

                ether 3e:fc:80:e3:8b:59  txqueuelen  0  (Ethernet) 

                RX packets 0  bytes 0  (0.0 B) 

                RX errors  0  dropped 0  overruns 0  frame 0 

                TX packets 29  bytes 9918  (9.6 KiB) 

                TX errors  0  dropped 0  overruns 0  carrier 0  collisions 0 

 

lo:            flags=73 <UP, LOOPBACK, RUNNING> mtu 65536 

                inet 127.0.0.1  netmask 255.0.0.0 

                RX packets 0  bytes 0  (0.0 B) 

                RX errors  0  dropped 0  overruns 0  frame 0 

                TX packets 0  bytes 0  (0.0 B) 

                TX errors  0  dropped 0  overruns 0  carrier 0  collisions 0 

Then

 

# iw dev 

phy#0 

               interface wlan1 

               wdev 0x1 

               addr  00:10:7a:75:60:f5 

               type managed 

If I do:

# ip a
1: lo:

2: dummy0: <BROADCAST, NOARP, UP, LOWER_UP>

3: wlan1: <NO-CARRIER, BROADCAST, MULTICAST, UP>


So, is my WiFi card using dummy0 or wlan1 or ?


Which one mentioned in the two scripts (unencrypwifi.sh & wpaencryptwifi.sh)?

Trying the unencryptwifi.sh script, I get:

 

#  

Error for wireless request "Set ESSID" (8B1A) 

   Set failed on device dummy0 ; Operation not supported. 

Listening on LPF/wlan1/00:10:7a:75:60:f5

DHCPDISCOVER on wlan1 to 255.255.255.255 port 67 interval 1 

No DHCPOFFERS received. 

No working leases in persistent database - sleeping. 

Any suggestions????

Thanks!

At home, tried connecting to WPA network....no go......




Noticed both power and link green indicator lights on Ambicom card are lit, but link light is solid green, not blinking. Is it supposed to be solid or blinking light?


Also, since this afternoon, when I do

 
# shutdown now 

nothing happens, does not shutdown like it used to.

?

Thanks.

Hi!
You cant use iwconfig with the libertas driver. You need to use iw! https://wiki.debian.org/WiFi/HowToUse#Command_Line
The best way to connect to a wifi is by editing the /etc/network/interfaces.

I never tried to connect to an unecrypted wifi, i will try this if i find time and write a little tutorial.

For shutdown try shutdown -h now. Or press CRTL + ALT + DEL

Stefan

Sorry there is some wrong information in my post! You can use iwconfig!!

Thanks, Stefan....

At work again....

Tried connecting to guest network using the 'unencryptwifi.sh' script from post back about 6 pages or so.....

Also tried with:

 
# iwconfig wifi0 essid "Your_SSID_without_quotes" mode Managed   

 

Error for wireless request "Set ESSID" (8B1A) : 

        SET failed on device wlan1 : Operation not supported. 

I searched the Error message and saw that a lot of people have gotten that error. But so far none of the suggested fixes have worked.

For reference, here's some info about 'wlan1':

 

# ifconfig  

wlan1:  flags=4099<UP, BROADCAST, RUNNING> mtu 1500  

                ether 00:10:7a:75:60:f5   txqueuelen  1000   (Ethernet)  

                RX packets 0  bytes 0  (0.0 B)  

                RX errors  0  dropped 0  overruns 0  frame 0  

                TX packets 0  bytes 0  (0.0 B)  

                TX errors  0  dropped 0  overruns 0  carrier 0  collisions 0 

 

# iwconfig wlan1 

wlan1      no wireless extensions 

 

Any suggestions?

Thanks.

Ok, it seems that we can't use iwconfig with this card, tried it and it also doesnt work for me.
A post from another forum:

"It sounds like either your kernel or the driver for the wireless interface will only support the newer cfg80211 configuration interface used by the iw tool, not the older wireless-extensions interface used by iwconfig."

If I find time, I will figure out a solution. But before I have to recompile CRDA to set the correct country code ...

Stefan

Thanks for your help, Stefan,

Well at least I know it's not about me........I think......




And won't spend more hours getting aggravated over this now....

What advantage is there running the newer 4.8.7 kernal over the 3.16.xx if any? Faster? More secure? Runs newer applications? How does this compare to the JLime 2.9? kernal? ( Not meaning to pester you ).See...now you have me learning about kernals!

About the Ambicom WL54 version 2.1 wifi cards...still a "potential"viable option for J720/Duvean?
Thanks in advance.

Oh, found the answer here: https://www.fosslinux.com/1015/what-is-linux-kernel-and-should-you-u...

Merry Christmas!! and what a fine gift you have given above...I finally learned enough Debian/Linux to figure it out and it works great! I installed midnight commander and DOSBOX..super fast and simple. Truly a great Christmas gift!

I got a hold of a WL54-CF Rev. 2.1 card and got everything installed via a Linux laptop and qemu, but I don't see the card anywhere. The J720 definitely notices when I connect/disconnect the card while running Devuan and prints messages about pcmcia connect/disconnect.

Are there modules that need to be loaded as well? `lsmod` outputs nothing

Okay, got the above figured out (forgot to untar the kernel 3.18 modules onto my CF card). Now I'm stuck at the exact same place as ArchiMark where I can't get any DHCP offers from my router.

What's interesting is I can see in my router logs (running OpenWRT) that the card is in fact trying to connect (WPA2 network), but it seems that something may be malformed regarding the request:

 
Thu Dec 31 05:09:20 2020 daemon.info hostapd: wlan1: STA 00:10:7a:75:7e:b8 IEEE 802.11: authenticated 

Thu Dec 31 05:09:20 2020 daemon.info hostapd: wlan1: STA 00:10:7a:75:7e:b8 IEEE 802.11: Station tried to associate with unknown SSID '' 

Unfortunately, that's as far as I can get. I've tried looking through the source code of hostapd to get more insight, but unfortunately it's not particularly helpful. Not sure it's worth the hassle of trying to debug this with wireshark

Hi jornadur,

I think once you got the modules loaded properly, you should be seeing the wlan or wifi device listed in iwconfig. If thats the case, then you need to setup “wpa_supplicant” and once that works put the dhcp client on top of that. I found the below article from ubuntu wiki helpful to sort things out:

https://translate.google.com/translate?hl=&sl=de&tl=en&u=https%3A%2F...

Note: If the card won’t associate with the access point despite correct key etc in the conf file, the card might need a FW update. If it’s a prism2 based card, the procedure is outlined here:

Kind regards
