Bugs in wireless WEP mode

Description

When using WEP mode and setting 10 digit hex key by Network manager, I never succeed in getting dhcp address. Checking with ifconfig, I see the key is set to be 104 bits, which should be 40 bits for 10 digit hex wep key.

Another strange behavior of the Network manager for WEP mode is treatment of key index. Setting my wireless station to be WEP mode of key index other than 1 and using Network manager, I sometimes succeed in getting dhcp address but mostly fail. Anyway the key index setting is NOT saved by the Network manager, and returns to the default value after reboot.

I checked these phenomena on PCBSD9.1(03-06-2013 amd64, i386). I don't know whether they are resolved in PCBSD9.2.

There was a bug in WEP mode in 9.0 and 9.1 versions. 9.0 and 9.1 are not receiving further updates and so this has not been made retroactive. This has been corrected in newer versions, and i'd recommend upgrading to a newer image / branch such as 10.0 release to take full advantage of all the awesome new features.

Best Regards,

Josh

I checked this on both PCBSD9.2(PCBSD9.2-RELEASE-p11-01-09-2014-x64-DVD-USB.iso) and 10.0(PCBSD10.0-RELEASE-p4-01-17-2014-x64-DVD-USB.iso). For 9.2, situation is exactly same as 9.1, that is,
no problem for 5 letter ascii key, and can not get dhcp address for 10 digit hex key, while wlan0
interface becomes "associated". For 10.0, situation is worse and dissapointing. The wlan0 interface
never becomes "associated" for both 5 letter ascii key and 10 digit hex key.
