Wireless networking has gotten better with Kubuntu 9.04, however there are still problems for users who do not have a card supported natively. If you have not purchased a wireless card yet, please take a look at the supported hardware at https://help.ubuntu.com/community/WifiDocs/WirelessCardsSupported.
If your wireless card has been detected, KNetworkManager will have a menu entry listing your wireless device. You can attempt to connect to your wireless network by clicking on the System Tray icon and selecting your wireless network. If you are able to browse the network with the a web browser, you have successfully connected to the internet.
With KNetworkManager you simple click the application icon in the system tray and select the wireless network you want to connect to. When you click on a network that has encryption enabled, you will get a pop-up dialog to enter this information. Once entered, this information is stored within the KWallet utility. This allows you to connect to that network in the future just by entering your KWallet password.
Opnaðu Konqueror, og reyndu að vafra á http://www.ubuntu.com. Ef þetta gekk, ert þú með fullkomlega virka internettengingu.
If the above did not work, open up Konsole
( → → ) and type ping gateway_ip_address
(substitude gateway_ip_address by the ip address of your gateway. This
address is usually 192.168.1.1, but may vary depending on the nature of
your network). If you are able to ping your gateway, then the DNS on your
computer is not working correctly. If you are not able to ping the gateway,
then you do not have a proper internet connection.
Command line: ( → → ) This will
open up Konsole providing you with a terminal or the
command line. Once you are sitting at the command prompt simply type
lspci
and press the Enter key. Locate
the Network controller: line as this will provide
information about your wireless adapter.
Það er mælt með því að þú notir aðra tengingu við internetið og lesir í gegnum hin fjölmörgu efnisatriði um þráðlausat tengingar. Eftirfarandi eru bara nokkris staðir til að skoða.
Síðan í útgáfu 2.6.17 af kjarnanum, hefur stuðningi verið bætt við fyrir þráðlaus Broadcom tæki. Þetta þýðir að sum Broadcom tæki virka strax, en samt eru enn mörg sem gera það ekki. Ef þráðlausa Broadcom tækið þitt virkar ekki hefur þú tvo kosti; bcm43xx-fwcutter eða NdisWrapper.
Með tólinu bcm43xx-fwcutter eru aðeins örfá tæki sem raunverulega irka. Til að sjá hvaða tæki eru nú studd skaltu skoða http://bcm43xx.berlios.de/?go=devices. Ef tækið þitt er ekki stutt er mælt með að þú notir frekar tólið NdisWrapper utility. Fyrir upplýsingar um hvernig á að stilla tækið þitt með bcm43xx-fwcutter tólinu skaltu skoða the section called “Broadcom” og til að stilla tækið þitt með NdisWrapper tólinu skaltu skoða the section called “NdisWrapper”.
Stilling á NdisWrapper krefst mikillar notkunar á skipanalínu. Það eru enn engin gluggaforrit til að aðstoða við þessar stillinguar. En þó að það sé gert í skipanalínunni, er einfalt að fylgja leiðbeiningunum.
This method is only supported for users of the Intel and AMD platforms. Users of older iBooks and Powerbooks cannot use this method. However, users of MacBooks (Intel based) should be able to use this method.
NdisWrapper er talið vera allsherjarlausn fyrir þráðlaus kerfi í Linux. Stór hluti af þráðlausum tækjum sem ekki er stuðningur fyrir, innbyggður eða með öðrum forritum, eru studd með NdisWrapper. Settu inn ndiswrapper með því að nota Adept. Ef þú kannt ekki við að setja innforrið er bent á að skoða skjalið Að bæta við forritum.
Once you have installed NdisWrapper,
locate the Windows drivers either on a CD or the
Internet. Drivers for Windows XP are preferred, however Windows 2000 drivers
will usually work just as well. Once you have located the CD or the drivers on
the Internet, copy them to a local folder on your system. In
some instances, you may have your drivers in a driver.zip
or a driver.exe
file. If it the file is in a
.zip
format, unzip the file by either
clicking on the file and selecting
Extract from the pop-up menu. If the file is in a
.exe
format, then install the
cabextract utility and open up
Konsole to navigate the correct directory. Once you
have navigated to the directory storing the .exe
file,
type cabextract filename.exe
. This will extract or
unzip the file to the directory you are in. The driver will be in the
.inf
format, so what you will want to do is type
sudo ndiswrapper -i filename.inf
and press
Enter. If successful you shouldn't receive any errors. This
command has gone ahead and loaded or installed the drivers in the
NdisWrapper module. To see if these drivers worked,
simply type sudo modprobe ndiswrapper
and press
Enter. Test to see if you have a network and/or Internet
connection.
If everything went well then the final step would be to load the
NdisWrapper module by default. To do this simple
type sudo sh -c "echo ndiswrapper >> /etc/modules"
and
press Enter. This will automatically start
NdisWrapper at boot time.
Ef ekki allt gekk svo veg, getur verið að vandamálið tengist ekki NdisWrapper heldur hugsanlega forritinu KNetworkManager. Til að athuga hvort KNetworkManager er um að kenna, ýttu á system tray iconið og veldu Hætta. Þegar KNetworkManager hefur hætt, farðu aftur í skipanalínuna og sláðu inn sudo modprobe -r ndiswrapper && sudo modprobe ndiswrapper
og ýttu á Enter. Þetta mun afhlaða NdisWrapper og svo hlaða því aftur. Eftir að þú hefur hlaðið því inn aftur skaltu athuga netkerfis- og/eða Internettenginguna aftur.
Síðan í 6.10 (Edgy Eft) útgáfunni, hefur kjarninn haft innbyggðan reklastuðning við sum Broadcom kort með því að nota tólið bcm43xx-fwcutter. Nú eru ekki svo mörg studd kort, en þróunin heldur áfram. Skoðau listann á http://bcm43xx.berlios.de/?go=devices til að athuga hvort kortið þitt er stutt. Ef kortið þitt er ekki á listanum, líttu þá á the section called “NdisWrapper”.
Til að byrja er það fyrsta sem þarf að gera að setja upp bcm43xx-fwcutter tólið. Til að fá meiri ypplýsingar um uppsetningu skaltu skoða kaflann Að bæta við forritum.
Once you have bcm43xx-fwcutter installed you can
read through a list of links to various drivers for your Broadcom device. To do
this open up Konsole ( → → ) and type at the
prompt zless /usr/share/doc/bcm43xx-fwcutter/README.gz
and press Enter. You have the choice of picking a driver from
that list, driver CD, or manufacturer's website. The file you are interested in
using is the bcwl5.sys
file. If you have the drivers in a
.zip
format, unzip the files to a local directory. If the
drivers are in a .exe
format, you will need to install
Cabextract. With
Cabextract, at the command line locate the directory
where you downloaded or copied the file to. Once there type at the prompt
cabextract filename.exe
and press
Enter. This will extract the file into the directory you are
in.
Now that you have the driver files extracted, navigate with
Konsole to the directory with the driver files. Next
you will use the bcm43xx-fwcutter utility to install
the drivers. To do so, at the prompt type sudo bcm43xx-fwcutter -w
/lib/firmware/$(uname -r) bcwl5.sys
. You may receive a couple of
warnings which are nothing to worry about. If it didn't work, it will provide
an error that states either driver isn't supported or the driver is to old. If
this is the case, you would repeat this step using one of the drivers from the
list in the README.gz
file shown above. If you continue to
have issues, connect to the Internet with another source and review the
following sites:
If you continue to have issues with loading the drivers, then you may need to use the NdisWrapper utility.
Now if you went through the driver installation without any major errors or
issues, the next step would be to load the new module you created in the
previous step. At the command line type sudo modprobe
bcm43xx
and press Enter. To see if the module
loaded and is working, at the prompt type iwconfig
and
press Enter. If it works it should return the name of the
interface as ethX where X is the number of the device. In
most cases it may be eth1 if you have a
CAT-5 Ethernet device already installed and configured. Also
to test and see if your device can scan, at the command prompt type
sudo iwlist ethX scan
and press Enter.
Don't worry if it reports no networks found as your
connection may still be working. Test and see if you can connect to your
network and the Internet. If everything has worked then you will want to add
the module so it will load at boot. To do so, at the command prompt type
sudo sh -c "echo bcm43xx >> /etc/modules"
and press
Enter.
