bom dia galera, ainda não consegui instalar o driver wifi do meu note, gostaria de um help de alguma pessoa que já passou por este entrave. Se alguém puder me ajudar a instalar e configurar agradeço desde então.
Baixei o driver especifico, e o mesmo veio com seguinte readme:

Release Date: 2010-0127, ver 0015
RTL8192SE Linux driver
--This driver supports RealTek rtl8192SE PCI Wireless LAN NIC
for
2.6 kernel:
Fedora Core 2/3/4/5, Debian 3.1, Mandrake 10.2/Mandriva 2006,
SUSE 9.3/10.1/10.2, Gentoo 3.1, Ubuntu 7.10/8.04/8.10/9.04/9.10,
moblin(V2), android-x86_090916, etc.
2.4 kernel:
Redhat 9.0/9.1

========================================================================================
I. Component
========================================================================================
The driver is composed of several parts:
1. Firmare to make nic work
1.1 firmare/RTL8192SE

2. Module source code
2.1 rtllib
2.2 HAL/rtl8192
2.3 wpa_supplicant-0.6.9.tar.gz (User can download the latest version
from internet also, but it is suggested to use default package
contained in the distribution because there should less compilation
issue.)

3. Script to build the modules
3.1 Makefile

4. Script to load/unload modules
4.1 wlan0up
4.2 wlan0down

5. Script and configuration for DHCP
5.1 wlan0dhcp
5.2 ifcfg-wlan0

6. Example of supplicant configuration file:
6.1 wpa1.conf

7. Script to run wpa_supplicant
7.1 runwpa

========================================================================================
II. Compile & Installation & uninstall
========================================================================================
You can enter top-level directory of driver and execute follwing command to
Compile, Installation, or uninstall the driver:
0. Change to Super User
sudo su

1. Compile driver from the source code
make

2. Install the driver to the kernel
make install
reboot

3. uninstall driver
make uninstall

========================================================================================
III. Start Up Wireless
========================================================================================
You can use two methord to start up wireless:
<<Method 1>>
1. Install driver like II. and reboot OS
2. Wireless will brought up by GUI, such as NetworkManager
3. If Wireless is not brought up by GUI, you can use:
ifconfig wlan0 up
Note: some times when you have two wireless NICs on your computer,
interface "wlan0" may be changed to "wlan1" or "wlan2", etc.
So before "ifconfig wlan0 up", you can use "iwconfig" to check
which interface our NIC is.

<<Method 2>>
Not install driver But Only load the driver module to kernel and
start up nic.
1. Compile the drivers from the source code
make

2. Copy firmware to /lib/firmware/ or /lib/firmware/(KERNEL_VERSION)/
cp -rf firmware/RTL8192SE /lib/firmware or
cp -rf firmware/RTL8192SE /lib/firmware/(KERNEL_VERSION)
Note: This depends on whether (KERNEL_VERSION) subdirectory exists
under /lib/firmware

3. Load driver module to kernel.
./wlan0up
Note: when "insmod: error inserting 'xxxx.ko': -1 File exists" comes
out after run ./wlan0up, please run ./wlan0down first, then it
should Be ok..
Note: If you see the message of "unkown symbol" during ./wlan0up, it
is suggested to start up nic use <<Method 1>>.

4. start up nic
ifconfig wlan0 up

========================================================================================
IV. Set wireless lan MIBs
========================================================================================
This driver uses Wireless Extension as an interface allowing you to set
Wireless LAN specific parameters.

Current driver supports "iwlist" to show the device status of nic
iwlist wlan0 [parameters]
where
parameter explaination [parameters]
----------------------- -------------
Show available chan and freq freq / channel
Show and Scan BSS and IBSS scan[ning]
Show supported bit-rate rate / bit[rate]

For example:
iwlist wlan0 channel
iwlist wlan0 scan
iwlist wlan0 rate

Driver also supports "iwconfig", manipulate driver private ioctls, to set MIBs.

iwconfig wlan0 [parameters] [val]
where
parameter explaination [parameters] [val] constraints
----------------------- ------------- ------------------
Connect to AP by address ap [mac_addr]
Set the essid, join (I)BSS essid [essid]
Set operation mode mode {Managed|Ad-hoc}
Set keys and security mode key/enc[ryption] {N|open|restricted|off}

For example:
iwconfig wlan0 ap XX:XX:XX:XX:XX:XX
iwconfig wlan0 essid "ap_name"
iwconfig wlan0 mode Ad-hoc
iwconfig wlan0 essid "name" mode Ad-hoc
iwconfig wlan0 key 0123456789 [2] open
iwconfig wlan0 key off
iwconfig wlan0 key restricted [3] 0123456789
iwconfig wlan0 key s:12345

Note: There are two types of key, "hex" code or "ascii" code. "hex" code
only contains hexadecimal characters, "ascii" code is consist of
"ascii" characters. Assume the "hex" code key is "0123456789", you
are suggested to use command like this "iwconfig wlan0 key 0123456789".
Assume the "ascii" code key is "12345", you should enter command
like this "iwconfig wlan0 key s:12345".

Note: Better to set these MIBS without GUI such as NetworkManager and be
sure that our nic has been brought up before these settings. WEP key
index 2-4 is not supportted by NetworkManager.

========================================================================================
V. Getting IP address
========================================================================================
After start up the nic, the network needs to obtain an IP address before
transmit/receive data.

This can be done by setting the static IP via "ifconfig wlan0 IP_ADDRESS"
command, or using DHCP.

If using DHCP, setting steps is as below:

1. connect to an AP via "iwconfig" settings
iwconfig wlan0 essid [name] or
iwconfig wlan0 ap XX:XX:XX:XX:XX:XX

2. run the script which run the dhclient
./wlan0dhcp or
dhcpcd wlan0
Note: Some network admins require that you use the hostname and
domainname provided by the DHCP server. In that case, use
dhcpcd -HD wlan0.


========================================================================================
VI. WPAPSK/WPA2PSK
========================================================================================
Wpa_supplicant helps to secure wireless connection with the protection of
WPAPSK/WPA2PSK mechanism.

If the version of Wireless Extension in your system is equal or larger than 18,
WEXT driver interface is recommended. Otherwise, IPW driver interface is advised.
Note: Wireless Extension is defined use "#define WIRELESS_EXT" in Kernel
Note: To check the version of wireless extension, please type "iwconfig -v"


If IPW driver interface is used, it is suggested to follow the steps from 1 to 6.
If wpa_supplicant has been installed in your system, only steps 5 and 6 are
required to be executed for WEXT driver interface.

To see detailed description for driver interface and wpa_supplicant, please type
"man wpa_supplicant".

1. load latetest source code for wpa supplicant or use wpa_supplicant-0.6.9
attached in this package.
Note: It is suggested to use default package contained in the
distribution because there should less compilation issue.

Unpack source code of WPA supplicant:
tar -zxvf wpa_supplicant-0.6.9.tar.gz (e.g.)
cd wpa_supplicant-0.6.9

2. Create .config file:
cp defconfig .config

3. Edit .config file, uncomment the following line if ipw driver interface
will be applied:
#CONFIG_DRIVER_IPW=y.

4. Build and install WPA supplicant:
make
cp wpa_cli wpa_supplicant /usr/local/bin
NOTE:
1) If make error for lack of <include/md5.h>, install the openssl
lib(two ways):

1> Install the openssl lib from corresponding installation disc:
Fedora Core 2/3/4/5(openssl-0.9.71x-xx),
Mandrake10.2/Mandriva10.2(openssl-0.9.7x-xmdk),
Debian 3.1(libssl-dev), Suse 9.3/10.0/10.1(openssl_devl),
Gentoo(dev-libs/openssl), etc.
2> Download the openssl open source package from www.openssl.org,
build and install it.
2) If make errors happen in RedHat(and also Fedora Core) for kssl.h,
please add lines below into Makefile

CPPFLAGS+=-I/usr/kerboros/include

5. Edit wpa_supplicant.conf to set up SSID and its passphrase.
For example, the following setting in "wpa1.conf" means SSID
to join is "BufAG54_Ch6" and its passphrase is "87654321".

Example 1: Configuration for WPA-PWK
network={
ssid="BufAG54_Ch6"
#scan_ssid=1 //see note 3
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP WEP104 WEP40
psk="87654321"
priority=2
}

Example 2: Configuration for LEAP
network={
ssid="BufAG54_Ch6"
key_mgmt=IEEE8021X
group=WEP40 WEP104
eap=LEAP
identity="user1"
password="1111"
}

Example 3: Linking to hidden ssid given AP's security policy exactly.
(see note 3 below)
ap_scan=2
network={
ssid="Hidden_ssid"
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk="12345678"
}

Example 4: Linking to ad-hoc (see note 4 below)
ap_scan=2
network={
ssid="Ad-hoc"
mode=1
proto=WPA
key_mgmt=WPA-NONE
pairwise=NONE
group=TKIP
psk="12345678"
}

Note:
1) proto=WPA for WPA, proto=RSN for WPA2.
2) If user needs to connect an AP with WPA or WPA2 mixed mode,
it is suggested to set the cipher of pairwise and group to
both CCMP and TKIP unless you know exactly which cipher type
AP is configured.
3) When connecting to hidden ssid, explicit security policy
should be given with ap_scan=2 being setted.
4) It is suggested setting ap_scan to 2 and mode to 1 when
linking to or creating an ad-hoc. Group and pairwise
cipher type should also be set explicitly, always with group
setting to TKIP or CCMP and pairwise setting to NONE.
Lower version wpa_supplicant may not allow setting group to
CCMP with pairwise setting to NONE. So if any problem, you may
try to set both group and pairwise to CCMP, leaving other
setting unchanged, when connecting to an CCMP-encrypted ad-hoc.
5) As for more config setting option, please refer to wpa_supplicant.conf
in wpa_supplicant.tar.gz that we provide.

6. Execute WPA supplicant (Assume module of rtl8192se has been loaded):
./runwpa

Note:
The script runwpa will check Wireless Extension version automatically.
If the version of Wireless Extension is equal or greater than 18, the
option of "-D wext" will be selected, otherwise, the option of "-D ipw"
selected.
