Wifi bağlantım kesildi

[Olorin]

Merhaba,

Sistemimde Linux Mint KDE x64 kurulu. Ağ adaptörüm için driver kurulumlarını kurcalarken internetten bulduğum bir .sh dosyasını çalışırınca tamamen wifi bağlantımı kestim. Şu anda Mint'ten ağa bağlanamıyorum. Yardımcı olabilir misiniz?

Dosyanın ismi "install-rtl8188cus.sh". İçeriğini .txt programı ile açtım, şu şekilde :

#!/bin/bash

# A very crude script to setup debian6-19-04-2012 to use Realtek RRTL8188CUS based Wireless LAN Adapters
# written by MrEngman.

# Update: 20/05/2012 - It is no longer necessary to edit the script to setup the network SSID & PASSWORD
# The script will ask you to input these values when it needs them.

# Update: 25/05/2012 - I have added an option to enable the wifi adapter to be hotpluggable.
# i.e. you can remove the adapter while the Pi is powered on and then plug it back in later
# and the wifi will automatically re-install and reconnect to the wireless network.

# Update: 08/06/2012 - I have compiled a new driver that overcomes the problems found using rpi-update
# recently. This driver also does not require additional firmware so is a little simpler to install.
# The script will detect if you have an ethernet connection and update the Pi's firmware and software
# automatically and download and install the new driver automatically if you have.
# If you do not have a network connection it will expect the old driver and it's firmware to be installed
# in the /boot directory of the SD card before running the script. The driver will be installed and the
# wifi started and then the Pi's firmware and software will be downloaded and installed. Finally the new
# driver will be installed to ensure the wifi continues working with the updated software.

# Update: 11/06/2012 - Updated driver to take care of latest rpi-updates

# Update: 17/06/2012 - Updated driver to take care of latest rpi-updates

# Update: 24/06/2012 - Updated to allow selecting a connection to an unsecured network or a secured network
# with either WEP or WPA/WPA2 security. Added option to enable DHCP to be installed or not as required.

# Update: 06/07/2012 - Major update. The script will now install, upgrade or repair the wifi driver.
# It will allow more than one wifi adapter to be installed, adding the rtl8188cus drive if another
# driver is installed, or add a second rtl8188cus adapter if one is already installed.
# The script can be run on a system with the rtl8188cus already installed to upgrade/repair the driver
# if it has been broken by a software upgrade.

# Update: 08/08/2012 - Updated to be able to use the script to add/update the wifi driver on XBian

# Update: 13/08/2012 - Added test to ensure script run by root. Added test to collect list of nearby
# wireless networks to check network has visible SSID available.

# Update: 19/08/2012 - Update for new wheezy version. Fixed bugs that put driver in wrong directory.

# Update: 25/08/2012 - Update for new driver for 3.2.27+ #66 PREEMPT

# Update: 30/08/2012 - Update for new driver for 3.2.27+ #90 PREEMPT

# Update: 31/08/2012 - Update to script and file downloads to ensure old version is overwritten correctly
# update for 3.2.27+ #96

# Update: 01/09/2012 - Update for new driver for 3.2.27+ #102 PREEMPT

# Update: 03/09/2012 - Update to check wifi adapter compatible with RTL8188CUS driver

# Update: 04/09/2012 - Update to enable built in driver to replace the previous drivers

# Update: 10/09/2012 - Updated the script to avoid having to hot-plug the wifi adapter
# to avoid kernel crashes when plugging the wifi adapter while the Pi is powere on.

# Update: 14/09/2012 - Updated the script to avoid conflicts when using apt-get upgrade and rpi-update
# Running rpi-update before apt-get upgrade can result in apt-get upgrade loading an older kernel version
# which has caused problems restoring a working driver.

# Update: 17/09/2012 - Update the script to avoid an issue where the driver may not be installed or a
# wrong version could be installed due to the driver not being untared from the tar.gz file correctly.
# Removed references to XBian. It has it's own version of script included in the XBian image.

# Update: 20/09/2012 - Disable the script from running on the new 2012-09-18-wheezy-raspbian.

Çok geniş bir betik, hem okumak güç hem de anlamak için çok çaba gerekiyor. Hem kablosuz hem kablolu bağlantın mı gitti? Uğraştırır biraz bizi, modülleri kaldırmamız ve bir şekilde yeniden yüklememiz gerekecek ki onu yapmak için de esas kaynağa gitmemiz gerekecek.
