I can tell you my settings in my AAO, it works OK and always I make so the conection.
TC2.11
My Acer is an AOA-110 without hard drive, it brings only a 8Gb SSD card. I mention this because I imagine that the wifi hardware is the same.
1st - TC will not turn on the indicator light when connected to wifi, so you should check that you are connected, once you are sure it is best not to touch it more. (You can check before you start with your original operating system, in my case was linpus)
2nd - you have to load the extensions:
wireless-2.6.29.1-tinycore.tcz
wireless-tools.tcz
if you want an easy connection tool extension : wifi-radar.tcz or wicd.tcz
and if you use encryption to wpa: wpa_supplicant.tcz
3rd - I make two types of connections, using different methods according where I am. In the case to connect at home, the connection is IP-specific, hidden and wep encryption, so I created a script for connecting straight away.
In the case out of home, with a free wifi, I do it with wifi-radar
4th- At home: open Control Panel and go to Network button, put wlan0 as interface. If you don't use specific IP then in DHCP yes, Save Configuration yes, press Apply and Exit . It will have created a wlan0.sh file in the /opt folder. In order not to lose the settings the next time you start add opt/wlan0.sh line to /opt/.filetool.lst.
If you use specific IP mark no DCHP , filled the other fields, Save Configuration yes, press Apply and Exit. Also add a line opt/wlan0.sh to /opt/.filetool.lst
4thA-Create in /opt a file with the name wconection.sh with the following contents:
#!/bin/sh
sudo /opt/wlan0.sh
sudo ifconfig wlan0 up
sudo iwconfig wlan0 essid "nameofyourconection"
sudo iwconfig wlan0 key yourencriptionkey
mark it as executable and add it to/opt/.filetool.lst. Instead of using wep encryption you use wpa encryption change the last line.
4thB-With the above, every time you turn the computer on, open a terminal window and type:
tc@box:~$/opt/wconection.sh
and you will have established the connection. Open the browser and navigate.
If you will check it:
tc@box:~$ ifconfig

5 ยบ - Out of home, without encryption, using wifi-radar.tcz
When running wifi-radar it will detect in the window all wifis nearby, with no lock is free, so simply select it and connect. If you choose one with a lock you have to specify the encryption key and then connect.
At home with wifi-radar I have to specify all the parameters of connection with IP's, passwords and other, having to do it every time I want to connect, so it is easier to implement the above method with a script.
Hope you get the connection. If you have problems you should start looking at dmesg to see if it correctly detects the wifi. (And make sure it is connected but the light does not turn on).
