I've tried the
rootsh dpkg -i wlantool_0.0.4_armel.deb
command, it installs the WLAN tool, I configured the connection again, and I used gconftool -R /system/osso/connectivity/IAP
,which displays the configuration details of the saved connection. And instead of "EAP_PAP_username" it displays "EAP_MSCHAPV2_username". This is truly strange. Again, in the settings wizard it is configured as WPA with EAP, TTLS, EAP PAP.
