Some weeks ago, I published this thread and I finished it without any solution... I want to post this thread again and try to find a solution to this problem... Here's the problem (The thread that I posted weeks ago):


I have a problem with mi wireless connection... I tried using 'ndiswrapper' and I installed the driver for my card (Realtek RTL 8187SE' and at the moment I don't have wireless... My 'eth0' connection works perfectly, but my 'wlan0' connection doesn't work...

My laptop is a Toshiba Satellite L505D-SP6905R...

If I type 'lspci' I receive the next message:

If I type 'iwconfig', I receive the next message:

The last one is because I installed 'VirtualBox'....

If I type 'rfkill list' nothing appears (After execute 'sudo rfkill unblock all' ) ....

I read posts on Internet and all the people say that 'ndiswrapper' is a good option to this problem, but as I said it doesn't work for me.... I installed the driver 'rtl-8187se' for windows 7 (Because my Laptop had Windows 7 before I install Ubuntu 10.10)...

At the moment, I've just re-installed Ubuntu 10.10...

I think that maybe the problem is that my wireless card is 'off' (Maybe)... But I don't know how to turn it on in Linux (I tried 'sudo ifconfig wlan0 up' and nothing happen)... Because I installed Ubuntu in the whole disk...

I type again: 'sudo rfkill unblock all' and then: 'rfkill list' and nothing happen...

I installed again Windows with Ubuntu, and If I turn the wireless on from Windows, I've got Wireless in Linux (Good news...) but the idea is to have only Linux in my laptop, so the problem here is to get working the keys Fn+F8 in Linux (That's the way as I turn on the wireless in this laptop)...

Somebody help me... Thanks in advance...

Unfortunately a lot of the information out there in the wild is horribly dated. If you check the Realtek page at linuxwireless.org you'll see that this chipset should work with the rtl8187 driver that is in the kernel. I haven't looked at your old thread, but if you were using an updated kernel and were installing ndiswrapper, you may have set up a conflict between the two drivers.

It isn't particularly clear from your post what is, or is not installed at the moment. If you have not installed ndiswrapper, then don't. If you have, it would probably be a good idea to remove it for now.

That is a possibility, but from your iwconfig output it looks like you haven't configured your card to connect to an access point. Have you tried to configure the card in NetworkManager? Also look at the output of lsmod and make sure that you don't have both rtl8187 and ndiswrapper installed (if you installed ndiswrapper).
