Hello Answer Gang,
This is my first time posting to you so I hope I get it right.
I am having big issues with my WiFi connectivity. Basically everything seems to be okay but attempting to ping an address results in a network unreachable message. I've used drakconnect to setup the wireless setup. The router itself is reporting the card as attached ! And ifconfig shows a continuous stream of traffic to the card but nothing from it.
The contents of /var/messages looks fine, apart from perhaps the last line:

Basically if never configures an inet address and I guess this is the real problem:

I have tried the following entries in modprobe.conf:

iwconfig gives:

I've booted the system using the Mandriva Flash drive and it's the same. I have built my own MadWiFi kernal modules and this method worked fine in 10.1 and Mand 2006 (the Mandriva 2007 supplied ones fail to load !!).
I have tried a SuSE 10 installation and this works just fine straight out of the box !
Sadly I need Mand 2007 due to h/w issues with the other distributions.
Can anyone shed any light on this ?
Many thanks, I hope you can help Owen

This is because your DHCP failed (see below).

This just means that the packets are being sent and received---but cannot be IP packets since your card did not acquire an IP address.
Here is the DHCP failure (or rather, DHCP lack of success)

You've got it.
Your iwconfig output was:

Is this output essentially the same as you get when you manage to connect successfully with SUSE 10 as you said below?

Did you send this mail to the Mandriva mailing lists? I hope you
didn't get flamed out of existence
Hope this helps.

Could you please foward your reply to the mailing list?
There are a number of reasons why:
1. The question/answer is meant to help the community as a whole. 2. There is a good likelihood that I will miss some point which the rest of the community will not miss.Regards,

Hello Kapil,
Many thanks for getting back. It's really good when someone actually replies.

> Did you send this mail to the Mandriva mailing lists? I hope > you didn't get flamed out of existenceI've dealt with the pre Novell Gnome, gNumeric and Evolution lot, Mandriva haven't even started on the flame ladder yet ! My relationship with Mandriva Cooker is now non-existent ! Basically I think they think I'm an irritating twit ! They no longer even reply to my posts; is this better than being flamed ? The Mandriva bug I filed hasn't been responded to. The most helpful has been the Mandriva Forums but the people who have so far looked at the posting have offered little in the way of actual help.
> Hope this helps.Not yet
The explanation was great. I now understand more what is
happening. I am still at a loss to know what to do about it !! What do I
do if a) it is the same as on the SuSE installation and b) if it isn't.
How do I correct the DHCP failure ? Is there a package I can downgrade
to the Mand 2006 version ? Is it just a case of rpm -qa | grep dhcp ?!
Thanks, Owen

Hello Kapil,
I could only get to my Mandriva 2006 partition which connects just fie. The iwconfig is the same except the Encryption key: is different !! I presume this is expected or the router would have denied access.
I also noted that in Mand 2007 the ath0 i/f is immediately assigned and inet6 address. In Mand 2006 it is never assigned and inet6 address.
If have installed dhcp-common and dhcp-client from Mand 2006 but still nothing.
** sigh **
Thanks, Owen

To use Alfred Hitchcock parlance, this is a "McGuffin".
The inet6 address is a "link-local" address. All ethernet interfaces have one in IPv6. (Perhaps all interfaces acquire one but I don't remember my IPv6 well enough).
In particular, this address was assigned by the Linux kernel and does not involve the DHCP server in any way.

Well, I've tried encoding a manual IP adress, netmask, gateway and DNS server 1.
The WiFi AP is 192.168.0.1, my assigned IP address is 192.168.0.2. The netmask is 255.255.0.0, the gateway is 192.168.0.1 and the first DNS server is 192.168.0.1
The NetApplet applet now shows a connected interface and shows a good signal strength. So I tried the following:

Herein there is a problem. You seem to have two interfaces connected to the same network 192.168.x.x --- these are eth0 and ath0.
Since the eth0 entry is higher in the table it will take prcedence. Try to DOWN the eth0 interface and see what happens.
ifdown eth0should do it.

I assume that the AP, the gateway, and the DNS server are all actually one machine/one interface. If you're saying anything else, then you have a problem right there - multiple hosts with the same IP on the same segment are a big no-no. Second, (not that this is a problem, but you might as well start out doing everything as "right" as you can) unless you have hosts which use the third quad of the IP (i.e., 192.168.2.X), your netmask should be 255.255.255.0.

OK, this would be the time to start doing the reduction process. You know that your packets aren't making the round trip from your host to the other one; why not? For the duration of the test, shut off/remove every non-critical piece that could get in the way of that (i.e., turn off any firewalls, remove any hubs/routers between the two hosts, etc.) and double-check any of the pieces that go in between (can you hook a cable between the two hosts and ping that way? If that works but the WiFi connection doesn't, what does 'iwconfig' report for that interface?)
All the other output that you've sent us demonstrates nothing more than the above test. It all says "no connection". Turn all that stuff off, test each piece in between, then start adding things back in one at a time. When the connection fails, you'll know what the problem is.

Linux does indeed provide you with complete access and lots of tools.
The biggest problem in cases like that is almost always operator error.

I have wondered about eth0, however I kept returning to the fact that WiFi works on a different partition running Mand 2006 on the same machine. The proof - I'm using Wireless now on Mand 2006.
On Mand 2006 route -n produces
Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 ath0 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 ath0Wow ! very different !
On Mand 2007 after a fresh reboot route -n produces
Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 35 0 0 ath0 169.254.0.0 0.0.0.0 255.255.0.0 U 35 0 0 ath0 0.0.0.0 192.168.0.1 0.0.0.0 UG 35 0 0 ath0There's no eth0 but where on earth did 169.254.0.0 come from. I've tried reconfiguring the interface but I cannot get rid of 169.254.0.0 nor can I find it in any configuration.
Thanks, Owen

Sorry, forgot to mention. The previous mail was when I hardwired this machine's IP address to 192.168.0.5. When I switch back to DHCP route - n produces nothing at all.

If that works but the > WiFi connection doesn't, what does 'iwconfig' report for that > interface?)I've shut off the firewalls and I have no intermediate hardware between the laptop and the AP. I have also attached a cable direct to the AP and everything works just fine. I'll have to get back to you on iwconfig as I'll need to reboot into Mand 2007. I think I've posted it before.
> The biggest problem in cases like that is almost always operator error.I hope you are right. I have begun to see others reporting the same type of issue. I am using WiFi to send this now from a different partition running Mand 2006 on the same machine.
I did an upgrade from 2006 to 2007 and a perfectly good WiFi connection was broken in exactly the same way. About the only thing I can think of is to install Mand 2006 and upgrade every package on at a time until WiFi breaks. Then try to regress the same package on Mand 2007 and see if WiFi now works.
Thanks Owen

I don't suppose FIXME is some indication ?!?!?! What is zeroconf ?

Zeroconf is a carry-over from MS wind0ws, which assigns an address to an ethernet interface (sometimes denoted by IF) in the event that nothing else has. Normally during (usually boot time) initialization of an IF, a protocol called DHCP is utilized to send a signal over a network to see if it gets a response from a device which may be listening for that signal. That signal notifies the listeneing device that there is an ethernet interface which is requesting an IP address. This mechanism provides a way of centrally managing IPaddresses which are going to be used on the network.
Zeroconf should only become activated if no device has responded to the broadcast signal sent out in search of an IP address. Zeroconf would assign an address in a range using the block corresponding to the 169.254.x.x address. The idea behind doing that is to try to garantee a connection between interconnected devices having ethernet interfaces in an environment where there is no device present listening for DHCP requests for IP addresses. Thus you can interconnect two machines which may be running wind0ws (or Linux) and have the capability of transferring data between them.
It seems as though there is an error in the zeroconf system init script where it fails to detect that the device already has had an IP address assigned - assuming that the zeroconf script is indeed being called after the script which initiates the DHCP request.
I would suggest that you try to disable the zeroconf script, at least temporarily. How you would do that with Mandriva I can't say, as I don't use that distro. I woulod guess that they have a menu entry which will lead you to the utility they most likely provide to do it.
As to whether that is the fundamental cause of your problem, I tend to doubt it, but I would disable it anyway.
