An example would be the Lenovo S10-2 which uses the 14e4:4315 rev 01 PCIID. Even after installing the correct driver the user would end up in a "trying to connect" loop. It would see the wireless SSID but when trying to connect to it, it would enter an reconnecting loop.

The solution was that this particular wireless device did not support 40 Mhz channels nor does it support 802.11N. The router in that case was actually broadcasting with a forced 40 Mhz and on WiFi-N only. When the router was set to Auto mode and 20/40 Mhz Channel, the wireless card worked correctly. This is a case scenario that also repeats in other cases, so a proper evaluation of the network equipment would help a lot.
