How To: Manual Network Configuration without the need for Network Manager

And this in another:

sudo dhclient wlan0

And just for testing purposes, try a simple password like fred or something. I want to make sure you are not having any transposition errors. Later on you can increase the numbers.

I have the same router as you -- and I can confirm this router should work with what you are trying to do!

This time I set it as fredfred as the router doesn't allow me to enter less than 8 characters.

Code:

cat /etc/wpa_supplicant.conf
ap_scan=1
ctrl_interface=/var/run/wpa_supplicant 

network={
        ssid="dlink"
        scan_ssid=0
        proto=WPA
        key_mgmt=WPA-PSK
        psk="fredfred"
        pairwise=TKIP
        group=TKIP
}

Code:

coppen@coppen-laptop:~$ sudo dhclient -r wlan0

this time
sudo wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd
is longer than before and some old lines disappear.

Now I have a doubt if my driver is working correctly. A few hours ago I booted into win xp and the wireless connection broken randomly. I search in website of the producer of my notebook and find out a new driver (the name is still realtek 8187 so I really don't know what version it is. But very likely it should be 8187B or 8187L). I reinstall it and it works great.

I compared the speed of copying big files in ubuntu and win xp by samba. I find out the speed in xp is around 2.6MB/s steady but in ubuntu it flutuates from 600KB to 2.2MB/s. That's a bit odd it keeps dropping to around 600KB/s for half a second and than goes up again. The signal strength in both OS is around 70%. And in both OS I notice no random disconnection. And WPA works well in xp too.

So should I reinstall the ndiswrapper driver? (The current driver in ubuntu is the windows 98 version as I mention in my previous post). Arrr... I am a noob and I forget the way how to get ndiswrapper work.. I need to search the forum again?

p.s. sorry for my bad english too

Why do you do this? Again, in one window do the wpa_supplicant thing, (do not stop it when it stops), and then in the other window do the dhclient command. You have to have wpa_supplicant running at all times (either in the foreground) or in the background (which can be done with use of the -B flag). However if you run it in the background you get no debugging output.

As far as the windows driver and things --- I don't know.

Lets try without ndiswrapper for now -- its the preferrable solution if it works!

**afeasfaerw23231233** · March 3rd, 2009

Sorry for my bad mistake. Now it works. Thanks a lot!

**kevdog** · March 3rd, 2009

Ok not to confuse you farther, however since you know it is working, you know longer need the -dd flag (this is a flag for double debugging output). I would now add the -B flag to send the process to the background. It would be something similar to this:

sudo wpa_supplicant -B -Dwext -iwlan0 -c/etc/wpa_supplicant.conf

Because the process is being run in the background, you can type the command and the dhclient command in the same terminal window.

Hi, it's me again. since by notebook freeze randomly at boot up [actually I started another thread about this issue:http://ubuntuforums.org/showthread.php?t=1085758 ], I want to reinstall ndiswrapper again. I follow another guide by you about installing ndiswrapper http://ubuntuforums.org/showthread.p...Kevdog&page=31
and I have problem while running this command:
sudo ndiswrapper -m

Code:

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

module configuration already contains alias directive

what should I do? thanks !

**kevdog** · March 4th, 2009

Ignore the warning. ndiswrapper is probably listed in /etc/modules

**afeasfaerw23231233** · March 4th, 2009

I want falling back to the native driver of realtek 8187 driver provided by Ubuntu by default because I doubt the ndiswrapper driver of win 98 version is the cause of freezing at "Loading manual drivers..." during bootup.

I clicked complete removal of ndisgtk, ndiswrapper-utils-1.9 and ndiswrapper-common in Synaptic. Then I run the following command according to your ndiswrapper howto http://ubuntuforums.org/showthread.p...ghlight=Kevdog in order to ensure a clean uninstallation:

Code:

sudo aptitude purge ndiswrapper
sudo rm /etc/modprobe.d/ndiswrapper
sudo sh -c "sed '/^ndiswrapper$/d' /etc/modules > /etc/modules.temp.rm; mv /etc/modules.temp.rm /etc/modules"
sudo rmmod ndiswrapper
sudo /lib/modules/`uname -r`/kernel/ubuntu/misc/ndiswrapper/ndiswrapper.ko
sudo rm -rf /etc/ndiswrapper
sudo rm /usr/sbin/ndiswrapper
sudo rm /sbin/loadndisdriver
sudo rm /lib/modules/`uname -r`/misc/ndiswrapper.ko

Then I check my /etc/modprobe.d/blacklist to ensure blacklist 818x and blacklisk 8187 are commented out. The extract of my /etc/modprobe.d/blacklist

Code:

# low-quality, just noise when being used for sound playback, causes
# hangs at desktop session start (Ubuntu: #246969)
blacklist snd_pcsp

#blacklist r818x
#blacklist r8187

then I run lshw -C network and the default driver seems not coming back. There is no driver installed for wlan realtek 8187?

Code:

 lshw -C network 
  *-network
       description: Wireless interface
       physical id: 2
       logical name: wlan0
       serial: 00:22:43:74:7b:05
       capabilities: ethernet physical wireless
       configuration: broadcast=yes multicast=yes wireless=IEEE 802.11bg

Here's the result of lsmod|grep 818

Code:

 lsmod|grep 818
rtl8187                53248  0 
mac80211              216820  1 rtl8187

usbcore               149360  7 rtl8187,usb_storage,libusual,usbhid,ehci_hcd,ohci_hcd

Thanks!

edit: and when I run modprobe r818x and modprobe r8187

Code:

coppen@coppen-laptop:/etc/modprobe.d$ cd
coppen@coppen-laptop:~$ sudo modprobe r818x
[sudo] password for coppen: 
FATAL: Module r818x not found.
coppen@coppen-laptop:~$ sudo modprobe r8187
FATAL: Module r8187 not found.

**kevdog** · March 4th, 2009

I haven't kept abreast of the latest realtek drivers within the newer kernels since writing this guide. I am no longer certain they are called r8187 or r818x. They could possibly be called something else. You are going to have to look keeping your kernel version as a reference. This can be found with uname -r. Google might be your best fried here!

**afeasfaerw23231233** · March 4th, 2009

Oh mine... I google around and cannot find any useful information. I think I have to go back to ndiswrapper.
I feel dizzy now......
