WiFi Router doesn't see Airport Express; Admin Utility does; No music :-(

Question

I brought in the Geeks on Call service after struggling for a long time to setup the WiFi Router, AX, etc. The Airport Express streamed music to my stereo for one day, before my computer restarted. Now I've lost connectivity. Here's the current details:
1) WiFi router's "Connected Devices" list does not show the AX; [Router is Netgear RangeMax Wireless Router (WPN824)]
2) Apple's Airport Admin Utility does show the AX (a.k.a. "Living-Room")
3) AX light is green, saying its connected to the network
4) iTunes speaker chooser only shows "My Computer"
Now for the bad news about what I tried that may have made things worse. Previously, the "Connected Devices" was showing the AX, but the Admin Utility was not showing it. The IP addresses of my Dell desktop & the AX were very close & I recalled the Geek saying it was a problem if they were too similar. So, I manually changed the 2nd to last # of the AX’s IP from 0 to 1. (i.e. from xxx.xx.0.x to xxx.xx.1.x) Now, I can’t login to the AX to change it back and the situation is as described above. (Its not accepting the password when I login thru the Admin Utility. I didn’t change the password from “public”.) [When I made this change, the AX started showing up in the Admin Utility and stopped showing on the WiFi’s “Connected Devices.” Previously, I had to manually enter the IP address in the Admin Utility to make it see it.]
I’ve tried: unplugging the AX; restarting iTunes; other “standard” passwords to login to the AX; waving my hands over it and making strange noises that scare my dog.
I admit it: This is an example of thinking I knew just enough to fix something, but ya end up worse off.
Thanks for the help!

Answer 1

Excellent. I'm all squared away. It works.
For the record, the steps were:
* Connect AX to WiFi Router with Ethernet Cable;
* Reset the AX with paperclip;
* Select Factory Fresh Profile
* Follow the steps in link above to "Join an existing Network..." including:
* In Network Name, enter name of my wifi net, as set in router setup
* Enter WEP password (even though your password may be all #s, I needed to select HEX)
* Select Update to send settings to AX;
* Once AX restarted and light is green (connected), unplug ethernet cable (should stay connected & green);
* Check iTunes and ensure it shows up in the speaker chooser;
* Unplug & move to electrical outlet near stereo and connect;
* It works...
