My other RTL8188CE gives the following output: 0e:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01) Subsystem: Realtek Semiconductor Co., Ltd.

Note, the RTL8188CE-VL does not work with wireless-next, but does with wireless-testing with some patches applied. I will contact the Realtek software team to ask questions about your card. I added my contact as a Cc here. In the meantime, could you try the wireless-testing tree? If your card still does not work, I will send you some patches to see what it takes. Larry
