Strange ipw2200 glitch
I installed "breezy badger" ubuntu and everything was properly configured to begin with with my wireless card (Intel pro wireless 2200) Infact it worked even better than under my POS windows that I have now had to resort to . . .

Then I just suddenly sortof stopped working. . .
iwconfig tells me that I am associated with various essid's and when in monitor mode, can gather packets via ethereal, kismet, etc.

But I am unable to retrieve webpages, it hangs then takes forever to decide that the page can not be reached

The ap I am attached to has internet.
I was fooling around with my mac address before i started having problems via

ifconfig eth1 hw ether <whatever>

I was also trying to get it conected to a wep encrypted netowork
iwconfig eth1 key . . .

But I was under the impression that restarting the interface (or rebooting the box) would re default all those things
After rebooting iwconfig shows the default mac address and no enc. key so I do not think that that is the culprit

It works under windows . . . any thoughts or help would be wonderful Thank you

Working at different AP
Is it possible that a router would blacklist you for some reason? It now works flawlessly at a different router that I wasn't fooling around with. . .

And if so, changing your mac address should completly resolve the issue . . . right?

Try manually associating yourself with an AP:
ifconfig <iface> down # just to make sure
ifconfig <iface> up
iwconfig <iface> ap <mac-of-ap>
iwconfig <iface> key .....
run iwconfig <iface> a few times with a few seconds delay.
See if your wireless car associated with the AP, check transfer speed, see if frequency remains constant
If the card associated with the AP and stays that way, check ifconfig <iface>
if no IP associated, run dhcpcd <iface> or dhclient <iface> or assign an IP manually
Check route, add default gateway if not there
Check /etc/resolve.conf for primary dns name (usually "nameserver <IP of GW>" works)
Thats all I can think of now.
Please repply if you need help.

One more thing: some programs that put wireless cards in monitor mod may leave it so and will not change it back to managed (what you should have for normal use).

Thanks for all the information. There is something strange about that AP and my computer . . . Everything seems to work perfectly everywhere else . . . *shrugs*

If it is blacklisted there is there some way to fix that? I remember reading something about filling the list with fake names or something . . .

If the AP did blacklist you and it belongs to you, try logging in and try to take yourself off the list. Maybe a reset would help as well. If however the AP belongs to someone else, contact their tech support for further details.
