The following reasons lead to the removal: - This driver generates maintenance workload - This driver has a maximum 54MBit/s as it supports only 802.11 b/g. Peak throughput is 3MBytes/s. - ping times can be 17ms are often above 500ms and worst case 22 seconds. One other user does not see such long ping times using a rasperry pi. I suggest deleting the driver as it no longer meets current expectations for throuput.
