Hi All
I'm after some wireless card advice. I have the latest Ubuntu installed on my wife's old:
HP Pavilion Pentium 4
and I'm using it as a build box. I need to go wireless. The machine has a couple of PCI slots free. What would people recommend in terms of a wireless card? How would I then go about setting it up?
I also have an old USB Belkin F5D6050 wireless adapter. I think it's only 16 bit. Could I use that? I have no idea where to start to set it up....
I have an Edimax wireless card bought from the Linux Emporium in my 7-year-old shuttle box at home, and it's happily running under Ubuntu 9.04. (It was less happy under 9.10 as the connection kept dropping, presumably due to a driver problem.) All I did was install the hardware and then install Ubuntu (I'd use Debian before then) -- the card was found and configured automagically, all I had to do was select the network and enter the password.
HTH.

Do you /really/ need to go wireless on that box? That belkin card is 802.11b standard. Depending on the other wireless devices on your network, this could impact on the network's performance as the AP negotiates down to the lowest common denominator device (i.e. the belkin at 11 Mbit/s - in practice likely to be no more than 5 Mbit/s). A newer PCI card such as the F5D7000 or Linksys WMP54G will give you 802.11g (54 Mbit/s) for around 20 quid. But you could also opt for one of the ethernet over powerline options such as Devolo, Solwise or Netgear produce (around 40-50 quid for two). I use the dLan kit on a couple of machines and the throughput (and reliability) is much better than wireless - but my house has thick walls.
I wouldn't worry too much about the setup. If you are using a recent 'buntu the drivers for most popular wireless cards should already be available - and of course if you opt for the "homeplug" type approach, then you don't need to worry about drivers at all.

Ok, so my DWL-G510 has arrived! However, I have no idea how to get it working. I've installed it in the PC and I have lights! And lspci gives me:
... 02:02.0 Network controller: RaLink RT2561/TR61 rev B 802.11g ....
I'm running ubuntu 9.10 server, so there's no GUI. Google isn't helping much either!
Help!

You could try putting something like the following in the /etc/network/interfaces file obviously using your SSID and WPA key:
# The wireless interface. This is connected to the local # wireless LAN which in turn is connected to the internet
allow-hotplug wlan1 iface wlan1 inet static address 192.168.1.2 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 # dns-* options are implemented by the resolvconf package, if # installed dns-nameservers 192.168.1.1 dns-search your.domain.co.uk wpa-driver wext wpa-ssid Your SSID wpa-psk yourwpakey
If you want to use DHCP you could go for something like:
allow-hotplug wlan1 iface wlan1 inet auto wpa-driver wext wpa-ssid Your SSID wpa-psk yourwpakey
HTH, Steve.
Hi
If you want to use DHCP you could go for something like:
allow-hotplug wlan1 iface wlan1 inet auto wpa-driver wext wpa-ssid Your SSID wpa-psk yourwpakey
Thanks for this.
A iwconfig suggests that my wireless adapter is wlan0. So I tried:
allow-hotplug wlan1 iface wlan1 inet auto wpa-driver wext wpa-ssid Your SSID wpa-psk yourwpakey
obviously with my SSID and my wpa-psk.
when I: /etc/init.d/networking restart
I get:
/etc/network/interfaces:19: unknown method
Line 19 for me is:
iface wlan1 inet auto
If I change that too:
iface wlan1 inet dhcp
Then I can restart nextworking, but there's no sign of wlan0. If I change too:
auto wlan1 iface wlan1 inet dhcp wpa-driver wext wpa-ssid Your SSID wpa-psk yourwpakey
and restart networking wlan0 tries to connected, but I get:
Listening on LPF/wlan0/00:26:5a:87:37:ca Sending on LPF/wlan0/00:26:5a:87:37:ca Sending on Socket/fallback DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 7 DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 9 DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 13 DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 21 DHCPDISCOVER on wlan0 to 255.255.255.255 port 67 interval 11 No DHCPOFFERS received. No working leases in persistent database - sleeping.
I'm still completely lost here......

Aren't you meant to be configuring wlan0? Why do you have wlan1 then?

To test that your wireless device can see the network, try:
$ sudo iwlist scanning
It should show you lots of details on all the networks it can see.

I'm not sure how hotplug and wireless devices mix. It's probably incredibly clever and would make completely unnecessary the manual approach I take, but on the other hand it could just be confusing.

allow-hotplug wlan1 iface wlan1 inet auto wpa-driver wext wpa-ssid Your SSID wpa-psk yourwpakey

I may be very out of touch, but I use wpa-supplicant to manage my authenticated wireless network connections. So I have something like:
iface wlan0 inet dhcp wireless-essid foobar pre-up wpa_supplicant -B -D wext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf post-down killall -q wpa_supplicant
in my /etc/network/interfaces
and then
ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=root network={ ssid="foobar" key_mgmt=WPA-PSK psk="password" }
in my /etc/wpa_supplicant/wpa_supplicant.conf
when I: /etc/init.d/networking restart
I get:

Still not convinved by all this 'auto' stuff.

In my experience, you get this when the wireless device is working OK, but it can't get an IP address from the router. This could be a DHCP issue, but it could also be an authentication issue.
There may be more information in your /var/log/messages.
Finally, if this is Ubuntu, why not try removing (or commenting out) *everything* from /etc/network/interfaces and allowing NetworkManager to do it all for you?

Can you do that from the command line with the server version?

I am sure the syntax with the WPA key in the /etc/network/interfaces file uses wpa_suplicant too and ifup starts wpa_supplicant with the necessary options. I can't remember now how I discovered it was possible to put the key there as previously I had been scratching my head about how/when to start it.

I'd double-check the WPA key. In my case the key did not contain any spaces - I don't know if there is any escaping required if it does (though my SSID does contain spaces and didn't need escaping).
I'd also check on the router to see which version of WPA it supports and experiment with that setting.

I don't know the answer to that, I'm afraid.

Oh yes, I'd forgotten you were working GUI-less.
I don't know the answer to that, I'm afraid.
What does your
$ man nm-tool
say? Apart from that, Google turns up at least one command line client for NetworkManager:
http://vidner.net/martin/software/cnetworkmanager/
But there's no deb for it.
Though the whole point of NetworkManager is that you shouldn't need to configure it at all. But I guess you do need a way to select a wireless network...
Hi All
Got it! In the end I booted up my EEEPC and got the configuration from there:
auto wlan0 iface wlan0 inet dhcp wireless-channel 6 wireless-essid oceaner wireless-key secret wireless-keymode open wireless-mode auto wireless-rate auto xncs-wireless-encryption wep
All seems to be working fine now. Thanks for the pointers!
