hi, everyone!

i'm facing a problem with wepon, so i would like to ask for some help:

i upgraded the power kernel from v49 to v50 yesterday, and when i tested whether everything is working fine, i tried wepon and saw the following error message:

"BusyBox v1.10.2 (Debian 3:1.10.2.legal-1osso30+0m5) built-in shell (ash)

the wifi was on, so i think there were wireless interfaces...
so i tried the followings: i downloaded the wepon, wepoff and the wifi.tgz again, and put them into the right folders, and typed the chmod +x commands. but it did not help, the error message is the same. is it possible that wepon is not compatible with power kernel v50...? (with v49 it run smoothly)

thanks,

jm
