Wireless Internet - works on Windows, doesn't work on Ubuntu Netbook remix

[decola]

Hi all, same old story.

Hi all,
I have a netbook computer running Ubuntu Netbook Remix.
I have just moved to a new house where the Internet is wireless.
I have no problem using the Internet when running Windows (my netbook is dual-booted). So it is not an hardware problem.
While on Windows I made a note about all the connection parameters.

On Linux, I access the list of wireless connections available.
I click on the one of my house.

At that point, there is the 'wireless security' dialog asking me for some information (as the connection is encrypted).
I selected 'WEP 40/128 bit key'.
I entered the key
I tried all the WEP index, from 1 to 4
As authentication I selected open system

With those parameters, the connection can't be established.

So I tried a different route.
I went to 'Preferences' -> 'Network connection' -> 'Create new wireless connection'.
I selected:
MODE: AD-HOC
MTU: AUTOMATIC
BSSID: left blank
MAC address: left blank
SECURITY: WEP 40/128 bit key
IPv4 settings METHOD: DHCP (automatic)
DHCP CLIENT ID: left empty
ROUTES: left empty

With those settings I can established a connection with the router but I can't connect to the Internet

Any idea? How can I debug this?

Is the Module installed/loaded


Give the response to the following commands:

ifconfig -a 
lspci

As always, you should read forum sticky's.

Sorry, for that. I have read the post and run the script to detect my settings.

I don't think it is a problem with modules/drivers because this netbook running Ubuntu does work with all the other wireless Internet connections I have tried. It just doesn't work at home!

Please help me, I am right in the middle of a server migration I have to use Linux and the Internet together. I am just desperate...


This is the output of the script (I have trimmed the lspci output):

Looks like you use the wrong kernel module.

Try:
RTL8187SE - Gentoo Linux Wiki

[waterhead]

Looks like you use the wrong kernel module.

The output of lsmod says that he is using the correct driver.

Module                  Size  Used by
rtl8187se             210204  1

Checking the section of Linux wireless.org dealing with this family of drivers, I did find this:

Unsupported Chips

* RTL8187SE (0x10ec:0x8199 and 0x10ec:0x8185 REV_22): This device will work with rtl8187se (currently in drivers/staging/), which is the vendor driver converted to compile with a 2.6.29, or later, kernel. A mac80211 version of this kernel is being developed.

Note the mention of using the 2.6.29 or later kernel. The OP reports using the 2.6.28 kernel.
