Hey,

I have had a look through some similar threads, but their solutions didn't work for me, so I'm hoping someone here can help.

I have installed Ubuntu 8.04 using the new "Install from Windows" option. As with all previous attempts I've had with installing Linux, I have had to use Ndiswrapper for my wireless drivers. However, even after following the installation instructions, NetworkManager never shows the wireless connection, even if the driver has installed correctly.

Here is a quick run down of my system and some output:

Toshiba Satellite L40-14N
Intel Pentium Dual-Core
1GB RAM
Windows XP (Ubuntu installed from XP onto a separate partition)

Ndiswrapper -l output

net8187b : driver installed
device (0BDA:8197) present

iwconfig output

lo no wireless extensions.

eth0 no wireless extensions.

Here is a link to the instructions I followed:

Thanks for the help.

Hi,
I have got the same problem,
I installed Ubuntu 8.4 and my wlan was not available.

I followed this Tutorial.I did this when I installed Ubuntu 7.10 a few month ago and it worked fine. But it looks like it does not work on Hardy.:HP 6715s (http://misread.de/wiki/index.php/Ubuntu_auf_einem_HP_6715s_Laptop_installieren_und_ konfigurieren)
It is a HP 6715s Nootbook, so the tutorial fits perfectly.

HP Compaq 6715 s
Turion 64 X2 TL-56 2x 1.80GHz
2048MB (2x 1024MB)

sudo ndiswrapper -l:
bcmwl5 : driver installed
device (14E4:4312) present (alternate driver: ssb)


sudo iwconfig:
lo no wireless extensions.

eth0 no wireless extensions.


I hope someone can help.

Thx

Thanks for the link, it helped, but my situation now is that despite being able to see the local wireless signals, when I connect, I am not able to access the internet. This could be because I have not set it up with a static IP, but when I do so, the Network Manager does not recognise the signal any more. Can anyone else help?

New iwconfig output:

lo no wireless extensions.

eth0 no wireless extensions.

wlan0 IEEE 802.11g ESSID:off/any

Edit: Actually, the following is the output I get from iwconfig when I am using the wireless only. I can't seem to find any consistency in settings that will allow me to swap between wired and wireless connections easily...

Hopefully a little more information will help. Here is the output from dhclient wlan0:
