how to install USB wifi adapter driver?

Bhanu999 · 08-26-2014, 11:49 PM

Hi, I'm using debian 7.6 OS.

I'm unable to install USB wifi adapter driver (Leoxsys USB wire).
I inserted the device in my USB port and checked it by using command
'lsusb', it has detected the device.
I have the driver software in a folder.
there is a file by name 'install.sh', I executed it by using command
./install.sh
but it has showed some error messages like this

Authentication requested [root] for make driver:
install.sh: 48: [: unexpected operator
cp: target `wire/driver/Linux/driver/rtl8188EUS_rtl8189ES_linux_v4.1.2.2_5805.20121116/include/autoconf.h' is not a directory

Install firmware-realtek it's available in repos or you can download the .deb here
https://packages.debian.org/search?s...rmware-realtek
You can use dpkg or gdebi to install it.

Bhanu999 · 08-27-2014, 01:38 AM

firmware-realtek is already installed

Do you know the name of the driver you're trying to install? I'm also using a realtek wifi dongle. Here's what my lshw command shows:

Code:

 *-network
       description: Wireless interface
       physical id: 3
       bus info: usb@2:2.4
       logical name: wlan1
       serial: 00:0b:81:ab:19:0a
       capabilities: ethernet physical wireless
       configuration: broadcast=yes driver=r8712u ip=192.168.1.67 multicast=yes wireless=IEEE 802.11b

You can see it uses the r8712u driver which I got from the firmware-realtek package.

Dmesg should be requesting the driver what driver is it asking for?

jefro · 08-27-2014, 03:21 PM

Exactly what chipset is this device?

Common steps for a nic.

Linux has the driver already.
Linux has driver but selected wrong driver.
Native linux driver available.
Ndiswrapper for native windows driver.

Start with finding out if you have a driver already installed before you go and build a driver.

thanks for all

I found the name of the driver which I',m trying to install
it is r8188eu

Finally I installed the driver by downloading it from github.com/lwfinger
I'm able to see the wire and wireless interfaces in the system tray (I'm using KDE)

but I'm unable to configure and activate wifi.

I have executed the lshw command and it shows the following.

*-network
description: Wireless interface
physical id: 1
bus info: usb@1:8
logical name: wlan0
serial: 00:e0:4c:1d:c5:20
capabilities: ethernet physical wireless
configuration: broadcast=yes driver=r8188eu multicast=yes wireless=unassociated

Please help me in configuring the wifi.

What network manager are you running? wicd? network-manager? something else?
jdk

Bhanu999 · 09-01-2014, 07:50 PM

I'm using network-manager (In KDE).

EDDY1 · 09-01-2014, 08:08 PM

Have you clicked on wireless icon & tried connecting to your network?

Bhanu999 · 09-01-2014, 09:27 PM

Ya I clicked on wireless network.

I'm able to see the list of other wireless networks.
I'm able to connect to the few of them for which I know the password.

But I'm not able to share the internet through my computer via wifi.

I created a new shared network.
I configured the network as per the following

In the wireless tab
SSID: dexter
Mode: Ad-hoc
Band: Automatic
Restrict to interface: Any
MTU: Automatic

In the wireless security tab
Security: WEP
Key type: Hex or Ascii Key (for 64 or 128 bit)
Key: (mypassword)
WEP index: 1 (Default)
Authentication: Open system

In the IPv4 tab
Method: Shared

When i click on the wireless network icon it is showing "configuring interface" and after some time it is showing connection failed.

EDDY1 · 09-01-2014, 09:36 PM

Is the machine thats configured for shared network a linux machine?
Did you edit ip-tables for it?

Bhanu999 · 09-02-2014, 06:30 AM

Ya it is a linux machine. I'm using Debian 7.6.

I Did not edit the ip-tables.

Bhanu999 · 09-03-2014, 09:48 AM

When I'm trying to connect to the shared network i'm getting the following error.

WPA Ad-Hoc disabled due to kernel bugs

This is a great resource for people having problems with their USB Adapters. That your original question which the dedicated members here has helped you resolve.

I followed the thread because I had input of which I was sure would get your adapter working.

Since you have it working, you might consider marking the immediate question/issue resolved and start a new issue regarding how to share networking. That is different from installing your usb adapter.

If you create a new thread and link to it, I'll follow that one and work with you on resolving your sharing issue.

I would consider that route more productive to the community and would be glad to help you with the new issue in a new thread.

Again, as far as the current thread, if the steps you took to install your usb adapter didn't work I would have referred you to: http://faq.apollo3.com/ljames/ubuntu/networksupport/ which so far hasn't failed. Jefro was about to point you to the Ndiswrapper which resolves NIC's that doesn't have native Linux support.

Again, I'll gladly proceed with helping to resolve your network sharing issue in a different thread.
