    Default wlan RTL8191se dropping connections


    I'm having problems with my wlan nic with BT5 R3 , installed on a laptop. It's RTL8191se and it's dropping connections when connected to my wlan network (WPA2-AES) or it cannot validate when trying to connecting at all.

    Below some necessary info:

    root@bt:~# dmesg | grep -e wlan -e 819
    [    0.000000] PERCPU: Embedded 28 pages/cpu @ffff88024f400000 s82880 r8192 d23616 u262144
    [    0.000000] pcpu-alloc: s82880 r8192 d23616 u262144 alloc=1*2097152
    [    9.075663] rtl8192se 0000:08:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
    [    9.075877] rtl8192se 0000:08:00.0: setting latency timer to 64
    [    9.158084] rtl8192se: rtl8192ce: FW Power Save off (module option)
    [    9.158136] rtl8192se: Driver for Realtek RTL8192SE/RTL8191SE
    [    9.158137] Loading firmware rtlwifi/rtl8192sefw.bin
    [    9.518028] ADDRCONF(NETDEV_UP): wlan0: link is not ready
    [    9.518601] bridge-wlan0: device is wireless, enabling SMAC
    [    9.518604] bridge-wlan0: up
    [    9.518606] bridge-wlan0: attached
    [    9.518634] bridge-wlan0: disabling the bridge
    [    9.545125] bridge-wlan0: down
    [    9.545149] bridge-wlan0: detached
    So it loads up allright and uses the right firmware.

    root@bt:/lib/modules/3.2.6/kernel/drivers/staging/rtl8192e# ls -all
    total 540
    drwxr-xr-x  2 root root   4096 2012-02-24 14:17 .
    drwxr-xr-x 46 root root   4096 2012-02-24 14:17 ..
    -rw-r--r--  1 root root 540936 2012-02-17 17:04 r8192e_pci.ko
    It also seems to use a recent driver. So would replacing this with the latest one from the realtek site make any sense???

    root@bt:~# airmon-ng
    Interface       Chipset         Driver
    wlan0           Unknown         rtl8192se - [phy0]
    Unfortunately it is not recognised by airmon.

    Does anyone else encounters this? Searching in the forum and in the Bugtrack list didn't reveal it.

    Anyone has some ideas to solve it?
