	I think that solid-green just indicates that you have successfully
'associated' (connected via radio waves) with the access-point.  But,
(and this is equally true for Windows as well as for Linux), there can still
be numerous other 'networking' things
that might not yet be set up correctly.  (The LED can't know about whether
this
other stuff is right or wrong.) Some of them are:
		o IP routing table ('route' cmd on Linux)
		o DNS (mapping of IP-host-names to their numeric IP-addresses)
		o etc (others that don't come immediately to mind)
	IP networking is a 'complex' subject.  Anyway, I'd guess that one
of these sorts of problems might be plaguing you.

	Here's a short tutorial...a hierarchy of tests that you can try
to help yourself understand more specifically where setup problems in IP
networking might be.  (It might be best to play with them at first on
a hard-wired WORKING system.) Remember, ORDER of these tests can be
important:
	(1) Try to 'ping' your own node numerically.  Use the special IP
		numeric address that is assigned to mean internal 'localhost'.  So, do:
		'ping 127.0.0.1'  (tests whether IP routing is setup/working INTERNALLY)
	(2) Try to 'ping' your gateway numerically.  (Your gateway would be
		a nearby external 'host'...e.g. your router/access-point or whatever.
		It might have an IP-address of something like 192.168.0.1 or something
		even wildly different than that...depends on specifics of YOUR NETWORK.)
		(Tests whether the path to your EXTERNAL wired or wireless is working.)
	(3) Try to ping an EXTERNAL host by 'IP-name'.  This test whether DNS (i.e.
		Domain-Name-System: the mapping of IP-names to IP-address) is setup
correctly.  		This mapping can be setup in more than one place.  It includes
places such
		as 'etc/hosts' file, where one typically might map a statically assigned
		IP-address to the IP-name chosen for your 'private portion' of your nearby
		network.  It can also be controlled in
		the 'resolv.conf', where you can specify one or more DNS-servers
		that handle this IP-name/IP-addr mapping function.  (And, one last
		caveat:  this 'ping' test will properly fail for cases when the
		a 'corporate-style' firewall has been setup to DISALLOW pings
		to propagate out into the real Internet world.  Those firewalls
		can be specific setup to allow higher-level (e.g. http 'browse' operations
		to google.com, yet dis-allow a 'ping' to that same IP-name or IP-addr).
		'ping google.com'

	Then, only when tests like these ALL PASS, can you expect that your browser
or whatever will be able to browse out onto the Internet.

Hope this helps...

Subject: R: [lwlan-user] network.opts ?

I've set up the file ifcfg-wlan0 with my IP address (192.168.1.2), the
address of the router (192.168.1.254), I wrote static instead of dhcp
and I set to yes the "on boot" option.

...but my wireless it does't work ! It is strange because the led on the
card is a solid green !

In particolary at  boot time appears the messagge "wlan-0 is not
present. The activation is posticipated" (translation from italian !!!!)

Please don't leave me alone !

Hi Laura,

you can set all your network-specific values in

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

Hope that helps.

Ciao
