How to get wlan0 to connect to the internet?

[leaded]

I'm using the D-Link DWL-G520. I followed all of the instructions from this page [http://ndiswrapper.sourceforge.net/w...p/Installation] and all seems to go well, but I don't know how to connect to the internet. I installed the driver that's on my supplied CD and the installation appears to have gone fine. I'm just to the point where I don't know what to do.

Going through the steps again after a reboot...

# /usr/sbin/ndiswrapper -l

# /sbin/modprobe/ndiswrapper

It gets a little tricky here, I suppose. The site says to do one of three things: ifconfig wlan0 up OR dhclient wlan0 OR dhcpcd wlan0. I start with the first one...

# /sbin/ifconfig wlan0 up
(nothing happens, let's try the second one)

# /sbin/dhclient wlan0

OK. I know the wireless internet is working, because I'm using it, sorta. Right now, I'm connected to the internet thru my Mac. It's sharing the connection via Ethernet to my machine, and it's using an AirPort card. I don't know what this DHCP thing is supposed to do. Also, if everything it working correctly, how do I make my computer connect to the internet via wlan0?? I've disconnected the eth0 connection, rebooted, and done the instructions to see if having two connections was an issue but, nothing happens. I'm not a linux expert and I'm confused

Thanks in advance!

Oh, btw...

I found this website [http://www.ces.clemson.edu/linux/fc2-2200BG.shtml] and I might give it a shot (with my driver though) but I figured I should try and get this working before resorting to a kernel recompile (since I've never done that before!)

[leaded]

Does anyone know?

[foobar]

I give both of these commands after reboot. Then I'm connected. My ifcfg-wlan0 is quite similar to the ifcfg-eth1 on the website you mentioned.

sudo /sbin/ifconfig wlan0 up
sudo /sbin/ifup wlan0

[james_in_denver]

ifconfig wlan0 192.168.2.10 netmask 255.255.255.0 up

route add default gw 192.168.2.1

That's assuming that my home network is 192.168.2 and that my road-runner router is 192.168.2.1.

The ifconfig line above defines an IP for the network card I am using, I don't use DHCP at home.

Just subsite an IP on your local subnet for the IP 192.168.2.10 illustrated above.

Your wireless route/internet hub is the IP in the "route add default" command above, just substitute your routers IP address for that one.

[Tolstyi]

Leaded,

I am working on the same issue. My card is up and is communicating with the router it seems, but I am not able to go online. Have you found a solution to your problem?

[Artemis]

This is how I nomally connect:

modprobe rt2400
ifconfig ra0 up
iwconfig ra0 essid -My SID, something like SpeedTouch blabla-
ifconfig ra0 10.0.0.201 netmask 255.255.255.0
route add default gw 10.0.0.138 ra0
iwconfig ra0 key -my personal WEP-key- open

[leaded]

Tolstyi, I'm using the MadWifi drivers. Check out http://madwifiwiki.thewebhost.de/wik...ndDLinkDWLG520

It's for Mandrake but it easily applies to Fedora 2

PM me with questions!

[Narcisso]

Ok just like Leaded I'm facing the same problem with the SAME WiFi card although I'm running Fedora Core 3 - mind you with no updates & also with DWL-G520 Rev A - an Atheros chipset. Moreover I'm using Ndiswrapper V.0.11;

I've setup for use with DHCP Server so is there any other info I can do besides the wlan0 up?
btw the link that leaded provided isn't working??

oddly enough the Internet Connection Control in FC3 does recognize my wlan0 as ndiswrapper - so I know its installed correctly; but when I try to connect via DHCP I get an error that card wasn't installed or something like that.
In wireless devices hardware; the DWL-G520 card is also listed as ndiswrapper; but the memory address isn't present & also the Interrupt Request is "unknown" ....in WinXP Pro (my other partition; I have the memory address and the IRQ is 16 but FC3 only will list up to IRQ 15! is there anything I can do in Terminal to querry the actual PCI Card DWL-G520 or even should I use the memory address that I have from WinXP?

thanks......ps leaded I cannot go the MadWifi part way to confusing and consuming ....just makes me welll "MAD".

[leaded]

I don't know what's with the IRQ assignments with the G520, but I share your frustration with wlan0 and ndiswrapper. It was detected for me as well but it was not working. And pretty damn frustrating!

You really should try and give MadWifi a shot. It worked immediately for me, where I wasted hours trying to get ndiswrapper to work.

Would you try MadWifi if it were RPMs? http://atrpms.net/name/madwifi/ Get RPMs for your kernel there. You'll need two files: the kernel module matching your running kernel, and the madwifi drivers themselves. If you can manage to find the right pair of files, there's nothing easier than running "rpm -Uvh *.rpm"

For me, when I did that in FC2 a few months ago, it worked like a breeze (I did the source method once, but I reinstalled FC2 for a sound card issue and did the RPMs that time). Kudzu should detect the card on reboot and even write the appropriate /etc/sysconfig/network-scripts/ifcfg-ath0 file. You'd probably want to re-write your own though. Here's my ifcfg-ath0 file...

STARTMODE=hotplug
DEVICE=ath0
BOOTPROTO=dhcp
NETMASK=255.255.255.0
ONBOOT=yes
WIRELESS=yes
WIRELESS_MODE=Managed
WIRELESS_ESSID=(your wireless ap name here)
#WIRELESS_ENC_KEY=(your wep key here, uncomment to use)
WIRELESS_RATE=54M

I'm going to try FC3 next week I think. I'll try and remember to post here how I got my G520 working (if I do!)

Good luck! E-Mail me if you need some help!

[Narcisso]

thanks for the advice Leaded.....the reason I'm iffy with MadWifi is because of the modules and other insanity....I don't even know which machine I'm running. I've got a Dell Optiplex forgot the model....but its got the P4 at 2.0Ghz I think its the brookdale chip (400Mhz front-side bus)....but when it comes to madwifi they want to know if its i386 (which I thought mine was) or i686 (what on earth is that?) or if its 64-bit which I know my machine isn't.

So onward with my results from FC3 & ndiswrapper v0.11.

ok this is my progress or lack of (i'm not sure which...) thus far:


I tried Foobar's information yet it just didn't work. Again its because I'm doing DHCP setup from the server.
[root@localhost ~]# /sbin/ifconfig wlan0 up
[root@localhost ~]# /sbin/ifup wlan0

Determining IP information for wlan0... failed.
So I tried James_in_Denver's advice....
[root@localhost ~]# route add default gw 192.168.0.100
SIOCADDRT: Network is unreachable

Ok a little more pertinent information....

Hmmmm being perplexed with this I figured i'd setup the essid with one of my neighbor's setup (he broadcasts his essid, no worries he because he MAC filters so I wouldn't interrupt his setup one bit. Oddly enough this is what I get (more information than I get) ...

Strangely when I tried in WinXP Pro to get connected with Dlinks software or even Windows Zero Configuration Manager for Wireless connection to essid BankoPhotographic, I noticed that I'll also be sending packets every few seconds and I'll ALWAYS receive 8 packets from his wireless router - Dlink software will show I'm connected just like windows but of course I'll never be issued a valid IP as my neighbor MAC filters. But for my own network I STILL cannot get ANY IP address? I should be getting IP 192.
When I then changed the “essid” back to my own network ... I get this ...

You've got an i686, but anything lower than that will work. Remember back in the day when you could buy a '386,' or a '486?' I don't really either, but I remember we had 486s in our computer lab in middle school. The Intel Pentium series I think introduced the i585 and somewhere along the line, maybe, MMX, it became i686. But I don't know about that. Basically, I do know that P3 and beyond should handle i686. I'm on an Athlon 3000+ and it's technically an i686, but should run i586 and lower binaries.

To find out for sure what your architecture is, open a shell...
$ uname -m

Mine reports back i686. To find your kernel, open a shell and...
$ uname -r

I know it's not what you want to hear, but I spent so much time with ndiswrapper, I honestly believe it will not work. MadWifi is the only way I could get my G520 to work.

If you want, run "uname -r" and post back what kernel you're running, and I'll find the two RPM packages for you.

Once you have those two files, you would simply run the "rpm -Uvh *.rpm" command to install them. The card should be detected on reboot. How much easier can it be than that!

Hi, there.

Linux : Fedora Core 2
Kernel : 2.6.5-1.358
Wireless Card : Linksys Wireless-G Notebook Adapter (WPC54G - PCMCIA)
AP : Linksys Wireless-G Broadband Router (WRT54G)

Add

/etc/sysconfig/network-scripts/ifcfg-wlan0

# WPC54G
DEVICE=wlan0
BOOTPROTO=dhcp
HWADDR="type your wireless card hardware address"
ONBOOT=yes

# Wireless
TYPE=Wireless
MODE=Managed
ESSID="type your essid"


and then

/sbin/service network restart

I am able to get IP address everytime I start linux box.

Good luck and correct me plz.

[Narcisso]

been busy for a while there sorry.

thanks for the info will get back in a day to let you know what my kernel is, Leaded and thanks.

jess glad to see FC2 is treating you well.....I had to goto FC3 (solved my earlier issue with MP3player/usbkey like butter). A little hesitant to try only because when I started FC2 with wifi card ON on boot I didn't see nothing but the error on the initialization screen. took me 2 days to get around that.

I'll keep it in mind though thanks.

[leaded]

I'm going to install FC3 tomorrow so I shall share my experience with getting my G520 working!
