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

Well, I guess that my guide also is not 100%. After a bit of testing I realized that it was missing one step. Even though the SSID information is stored in the card somewhere, I believe that when Linux reinitializes the card, it stays in limbo mode until you tell it to connect to the SSID again. So here are the full steps:

1. Configure the card on Windows CE as usual. Use the Aironet app to setup SSID information and make sure the connection works (open something on Pocket IE).

2. Boot into Linux and login as root.

3. To power up the card:

ip link set dev wifi0 up  
ip link set dev eth0 up

(apparently this card needs to be enumerated with both wifi0 and eth0). Once you run those commands, the LEDs on the card will start flashing and it will automatically connect to the SSID configured previously on Windows CE. 4. Connect to your SSID. I issued this command for both interfaces wifi0 and eth0. Not sure if it only needs to go to one of them:

iwconfig wifi0 essid "Your_SSID_without_quotes" mode Managed 
iwconfig eth0 essid "Your_SSID_without_quotes" mode Managed

5. Obtain an IP address from DHCP:

dhclient -v eth0

6. Or alternatively, if you want to set the card with static IP:

ifconfig eth0 "Your_fixed_IP_without_quotes" netmask 255.255.255.0 up 
route add default gw "Your_gateway_IP_without_quotes"

That's it!

Both are good wifi cards but limited to WEP...no longer considered secure, so using an old wep router as a home subnet is a common use.

Orinocco card requires the Agere/lucent driver which can be downloaded as a zip file contained the lucent.cab on this site. Choose Arm version.

The Aironet card driver is part of the stock rom on the J720 and configuration app is found Start => programs =>communication=> Aironet setup and Aironet WEP (password is "Aironet".

IMO, it's a bit of a dance to get wifi working. Go into settings=>control panel =>network. Pick the Aironet or lucent driver (WLAGS:Agere), open properties and set a static ip address, subnet, and router gateway, primary DNS is router address... (IMO static address works more consistently than DHCP).

Then programs=>communications=>remote networking=>make new connection=>name it=>direct connection=>next=>usb on comx=>tcpip settings=>set static ip=>set server (router) ip.

In control panel =>communication properties=>change device name to a specific ID on network=>PC connection=>change to your connection name from drop down menu.

Tweaks2k2 programs is great for setting up network file shares.

Some of the above may or may not be necessary and sound a bit like VooDoo....but it works well for me and you can waste hours trying to catch your tail. This way you have all the bases covered! Good luck.

Thanks, Joval!
With new devices, I usually try neverssl.com first, so that it redirects to the guest network page.

For this do the following steps:
You have to edit your sources.list

vi /etc/apt/sources.list

to this line "deb http://deb.devuan.org/merged ascii main" add "non-free" it should look like this:

deb http://deb.devuan.org/merged ascii main non-free

After that insert your ethernet card, or working wifi card (you need a internet connection) and do an apt update. Now you can install the required packages
apt install firmware-libertas

Hi!
You need at least a Rev: 2.0 card!
Older revisions work with a little driver hack - but the wifi connection is unstable, so i dont recommend that!
