Wireless-N300 PCI Express Adapter
"1244-00000775-50Z_ES" (or something) is silkscreened on the board in the FCC photos.
- OEM: Edimax EW-7622PIn
The PCIe wireless card bases on the Realtek RTL8188CE (1x1x1 ?) chipset.
- This chipset is supported by the Linux kernel since version 2.6.38-2
- and recognized by the kernel in the following way:
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01) [10ec:8178] Subsystem: ASUSTeK Computer Inc. Device [1043:84b6]
The PCE-N15 is controlled by the kernel module rtl8192ce
- This drivers is loaded automatically by the kernel:
rtl8192ce 0000:02:00.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18 rtl8192ce 0000:02:00.0: setting latency timer to 64 rtl8192ce: Using firmware rtlwifi/rtl8192cfw.bin ieee80211 phy0: Selected rate control algorithm 'rtl_rc' rtlwifi: wireless switch is on
Furthermore, Realtek provides the kernel module for download at their homepage.
- To compile this driver under Ubuntu the following packages have
- to be installed first: linux-headers-generic and build-essential.
- Afterwards, the driver can be unpacked and compiled:
sudo su make clean make make install
Unfortunately, the quality of the Linux driver seems to be low and several Linux user experience
- disconnctions and other problems with the WiFi card or the RTL8188CE chipset.
As a remedy it is suggested to deactivate the hardware encryption of the card.
- In this case, the module has to be loaded by the kernel with additional
- options, which can be given in the file /etc/modprobe.d/rtl8192ce.conf:
/etc/modprobe.d/rtl8192ce.conf options rtl8192ce ips=0 fwlps=0 swenc=1
