(This is configured by the network GUI tool) You might want to man interfaces and ifup to get a feeling of what is going on. A simple problem that you might have is that your wireless interface (eth1 or whatever) might not be marked as auto. auto ath0 is not put in the configuration file by the Ubuntu install, but I tried putting it there without result. I'm slightly familiar with the interfaces file. I've done a kludge which works, although it's pretty ugly. I've configured both eth0 and ath0 in the interfaces file, and put a three line script in /etc/init.d/rcS.d which removes the route to eth0 after the network comes up. #!/bin/bash route del default eth0 echo Horrible Kludge That actually works! I can't say I really know why. If I don't remove the route, there are two default routes which causes networking to get confused. Needless to say, I'm not using ethernet :-) The only good thing is that the people using the machine will never know how ugly that is. Also of consideration is that depending on how your wireless interface is physically integrated (my HP/Compaq laptop uses a special USB interface) might also determine when it is available to be upped (it might be hotpluggable). Do you have a Function-F2 or somesuch that turns wireless on or off - this might also cause the non-appearance of the device? The pcmcia card is hotpluggable (which I only know because it comes to life during the hotplug boot process). I don't know anything about a special function key (how would I find out? is this hardware specific?), but the wireless always connects but only after eth0 is activated. You probably need to check out the tail of /var/log/kern.log and /var/log/messages for pertinent warnings/errors. I've left it at the office, so next time I've got the machine in my hands I'll check the logs. For some reason I didn't think to do that. Lots of other people seem to be using the atheros cards without any problems, so I guess it's something specific that I'm doing. This problem exists after a bog standard, unammended Ubuntu Hoary install. Many thanks... David. I can't get my wireless to connect at boot. This is causing me embarrassment because I keep telling everyone they should use Linux :( From a fresh install of Ubuntu Hoary, specifying wireless for my net connection, wireless fails to connect. Signal is NOT a problem. HOWEVER: If I deactivate wireless, manually create an ethernet connection with the network panel, activate ethernet, deactivate ethernet, then activate wireless.. i get my wireless back! I've been able to replicate this consistantly. Simply restarting networking doesn't work. I have to go through that ritual. Without doing that, all the settings in the network panel look OK but the MAC address shown by iwconfig is FF:FF:FF:FF:FF:FF and the flashing lights indicate no connection. ifconfig gives the right ip address etc and route shows the right gateway (192.168.0.1) on ath0 Dell Inspiron 4000, Netgear WGT624v2 AP, Netgear WG511T pcmcia card, atheros chipset, using WEP 64bit key and static IP. This is getting to be a showstopper for using Ubuntu. Works fine for WinME dual booted on the same machine :( If anyone is getting good results using a similar set up, I'd love to know what I'm doing wrong. regards... David. PS: i've tried apt-get update, apt-get upgrade but that made no difference. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Would a half-bridge setup work for you? That's how I have my modem set up. I
gave it a NAT rule to forward all packets to my GNU/Linux firewall/router,
which decides what to block, what to accept and what to forward to client
workstations.
The end effect is similar to a full-bridge mode, but the modem handles the
ADSL connection. I don't need to mess around with PPPoE clients on the
router. This setup also allows me to connect via PPPoA, which I find to be a
little better than PPPoE (YMMV).
Personally I'd just go with Internode (no I don't work or have any
association with them, just had good service) but then I'm not the one
making the political decisions.
I am with Internode and I think they're excellent. Their CEO is a big Mac fan,
and as a company they are very friendly towards users of alternate OSs (i.e.
anything but Windows).

[SLUG] Retreiving data from a borked CF card
Dear Dr Slug, I have a flash card out of my camera that I'm pretty sure still has some pictures on it. The camera recognises the card but says its empty. If I put the card in my card reader, Linux refuses to mount it (same with MacOSX and 'doze). I've had something similar in the past, but I as able to mount the card, dd the information off it and retreive the pictures from the dd image using a Python script I wrote. However, this time, the card won't mount, although the camera reads it quite happily. Anyone have any ideas?

one going to the Lan. Do you just run a private IP network between the

Thanks for the tip
Yes, I have two interfaces on the Linux router. My setup is as you described:
eth0 goes to the modem and eth1 goes to a hub for the client machines. I have
a private IP network between eth0 and the modem and another between eth1 and
the clients.
I don't think two interfaces on the router is a requirement, though. I think
you can get away with only one interface, provided that all the client
machines have the router listed as their gateway.

[SLUG] Erratic wireless connection (sound footnote)
Hi all, I have 5.0.4 installed (dual boot with Windersninetyeight) on an old Compaq 7770DMT Armada. I have a D-Link DWL-650+ wireless card - picked up by Ubuntu 'out-of-the -box'. I've set everything to default (on the w'router) so there's no WEP etc. This is in my living room - the only place I can get a wireless connection. Ubuntu recognises the card and I've set the wlan0 as default and it starts on boot BUT the connection seem quite unstable with Ubuntu but less so with Winders (!) - is this something to do with Ubuntu's connection to the card Is there a wireless signal strength app I can install to check what it's able to 'see'? Is there something else I need to look at? I'm new to wireless in Linux, and so would appreciate any assistance able to be offered. I'm assuming there are other settings I need to change, but I'm afraid I'm not sure where to start. (Footnote.
