Status

Some people have experienced stability issues transfering large files, the alternative hostap driver handles such problems a little bit better, but still suffers from it.

Some people have suggested that upgrading the firmware will solve the problem.
Have a look here for firmware flash tools and firmware files.

WARNING IBM will most likely not support these firmware upgrades, if it breaks your hardware it is your problem.
