@everyone i followed the readme file. it is for kp46. i installed the debs accordingly. i was using kp49 and after that my device went into a reboot loop. how to install the drivers?
i flashed my N900 and with some help i managed to understand a bit. all i did was:

untarred the tar file.
cd /home/user/MyDocs/wl1251/binary/compat wireless
sh load.sh

THATS IT ?
