Have you tried resetting the Airport Express?

Got a question about technology? Ask it here. Discussion of hardware, software, TiVos, multi-region DVDs, Windows, Macs, LINUX, hand-helds, iPods, anything tech related. Better than any helpdesk!
Yep, same problem. I'm going to unplug it for a few hours and will check it again when we get home later. If anyone has any insights in the meantime, I'd appreciate them!
check to make sure you have updated the firmware, do a hard reset, and reinstall everything. those are my suggestions in that order.
Nice!
iTunes is warning me that this update may take over an hour. Probably not worth it since I'm planning to upgrade this month anyway, but I guess it's too late to stop now...
[Holy crap, over two hours and still going. Is restoring the media the last step?]
[Apparently not. Now it's re-optimizing all my photos. Oy.]
I have determined that I know just enough to be dangerous with this stupid Airport Extreme (not express). I updated the firmware, which was indeed woefully outdated, but that didn't work. Then I checked to make sure it was configured correctly for the stupid DSL, which it seemed to be. Restarted again. Didn't work. I tried futzing around more to no avail. Now im getting this warning: "99.60.19.121 in use by 00:0d:93:fa:11, DHCP Server 192.168.0.1". Um. WTF?!?? Also argh.
And now I'm back where I started. One computer can get one, but if I try to get the second laptop on I get a "Another device on the network is using your comouter's IP address (99.33.199.213)." Gah! I hate DSL. And my own incompetance.
Ftr, I tried to do a hard reset but since I currently have exactly one Ethernet cable and therefore can either connect my laptop and the airport OR the airport and the DSL modem but not both at the same time, I couldn't go through with it. Argh!!!
Pix, In network in System Preferences, try clicking on the airport, and clicking "Advanced" hen under tcpip, change ipv4 to manually, set the P to 192.168.0.100, with the gateway and router to 192.168.0.1, with a subnet mask of 255.255.255.0 and under the DNS tab add 192.168.0.1 as well.
Turn off IPV6.
99.33.199.213
This is suspicious, the computers should not be getting IP addresses in this range if they are behind the DHCP server that the Airport Extreme is providing. The computers should have IP addresses that are in the 192.168.x.x range or the 10.0.x.x range. I'm wondering if there is something on the DSL end of things that the provider has messed up and as such the DSL router is the device that is sharing an IP address. Check each of the computers and see what IP address they are being assigned, you can find it under the network tab in the preferences pane.
