Hi kazmam5,

"Realtek PCIe FE family controller" is the NIC or Ethernet controller. The WLAN cards shipped with the Inspiron N5110 were Bluetooth combo cards. You must choose the drivers for one of the following:

1.	Dell Wireless WLAN 1701 Half Mini-Card + BlueTooth 3.0
2.	Dell Wireless WLAN 1702 Half Mini-Card + BlueTooth 3.0
3.	Intel Centrino Wireless-N1030 Half Mini-Card + BlueTooth 3.0
4.	Intel Centrino Advanced Wireless-N6230 Half Mini-Card + BlueTooth 3.0

The other WLAN card that is offered with the system are:

1.	Dell Wireless WLAN 1502 Half Mini-Card
2.	Dell Wireless WLAN 1503 Half Mini-Card
3.	Intel Centrino Wireless-N1000 Half Mini-Card
4.	Intel 6150 WiFi / WiMAX Half Mini-Card

To identify the correct WLAN card in your machine follow the below mentioned steps:

1.	Press and hold "Windows key" on the keyboard and press the key "R".
2.	Run dialog box will be displayed.
3.	Type "devmgmt.msc" (without quotations marks) and hit Enter.
4.	Expand Network Adapters and check which one of the cards (listed above) is present in your laptop.
5.	Click here to open the support site.
6.	Enter the "System Service Tag Number" in the box below "Enter your Service Tag to get started" and click "Submit".
7.	Under the Network section download the WLAN driver for the card present in the system.

Hope this helps.

Hi kazmam5,

Have you checked under "Unknown Device" in "Device Manager"? If not, please check if the Wireless card is listed there. If you are not able to see the Wireless Card in the Device Manager, the wireless card might not be detected by the system. Take a technician's help or by yourself try to re-seat the Wireless Card (refer Service Manual for detailed steps on how to remove the wireless card and safety tips). The WLAN Mini-Card slot on the Inspiron N5110 / 15R system is located at the bottom of the palm rest.

First four wireless cards are Bluetooth combo cards while the later four cards do not have Bluetooth capability but are compatible with Inspiron N5110. If you replacement wireless card is one of the later four cards Bluetooth will not work in your machine. Please check the Device Manager to identify the wireless card installed in the machine.
