Forest Bond contributed this driver in 2009. 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 but this lasts only for a second. Typically throughput is 1.7MBytes/s. - Depending on the number of devices on the channel the device looses connection and cannot reconnect for 5-60 seconds. Watching a youtube video is OK because of the buffer. But surfing can then be really a pain. - Its form factor is mini PCI (not miniPCIe) that is old and large. - Hardly not to buy.

Entry for "VIA VT665X DRIVERS" is still in use for vt6656.
