For my experience is not a router problem nor a wireless
card problem.iwconfig has nothing to do with this issue
you can use how many parameter and the order you want.
The problem can be focused on which firmware uses the
wireless card driver or on which version of dhclient is
used on the machine.
I've experienced this problem with Ubuntu 7.10.
Ubuntu 5.10 works perfectly on the same machine inclusive
wireless.
I cant start Fedora since version 7 because it crashes due
to the version of xorg used.
Newer Linux doesn't mean better but worst for older
machines.

Hmmm,.."No DHCPOFFERS received."
1) DHCP server not turned on?? (You have likely checked
that three times
already!)
it's on. and DHCP is giving out addresses to wired
computers nicely.
2) No remaining available DHCP addresses? This one got
me: I set up for
only two then tried a new (third) unit, forgetting that
the printserver was
using the 'spare' address.
50 addresses available.
3) More insidious: whoever set up the Linksys turned on
MAC filtering, so
no DHCP Offer will *ever* be sent. After I fixed problem
#2, it took me
a....further...while to figure out this one. And it's
kinda hidden in the
linksys setup structure ( I use the DD-WRT BIOS on my
linksys, and it is a
little more friendly).
checked that first thing. absolutely no filtering.
4) I found that iwconfig is order dependent and
sensitive to too many
settings being tried at once. The ESSID setting has to
be LAST. (Thank you to
somone on this list!)
hmmmmm ... i don't remember reading that. or maybe i
just glossed
over it. in any event, i did check all the basic stuff
before
proceeding to whine about it. i'll play with this more
this weekend.
