Air 1142 beginners problems

Hi guys!

I've bought a AIR-AP1142N-E-K9 to test the wireless n features. I've gone for the 1131 till now.

I bought a AIR-PWRINJ3= and a AIR-PWR-B= for this. The PoE injector doesn't seem to work with the AP.

I read that you had to use the AIR-PWRINJ4= PoE injector. Why is this? It is like 3 times the price.

Ok, I configured it for my needs, which is 2 SSID's and 2 VLAN. The config was copied from my old 1131, I would be sure the trunking and stuff would work properly  - it did
 
I have this setup on the AP:

alfa is a open public network
bravo is a non-broadcasted network for office users


dot11 SSID alfa
   vlan 400
   authentication open
   guest-mode

dot11 SSID bravo
   vlan 401
   authentication open
   authentication key-management wpa
   wpa-psk ascii 7 ***********************

interface Dot11Radio0 (same goes for Radio1)
ssid alfa
ssid bravo
encryption vlan 401 mode ciphers tkip
power client 30
channel 2412
station-role root
rts threshold 2312



This is the issues I have:    

I Windows 7 wireless utility, I've added the bravo SSID + Pre Shared Key.

I can't see the powerlevel (the 5 bars) when I'm not connected to the bravo SSID. But when connected, it functions perfect.

The autoconnect feature will not work for this non-broadcasted network when checked int the settings tab for the SSID in Windows. (I've checked the Connect to this SSID eventhoug not broadcasting)

Any suggestions why this setup doesn't work as planned?

Id say The AP requires more power than a standard PoE injector, hence the more expensive adaptor
Cisco Website datasheet:
>This additional power may be as high as 2.45W, bringing the total system power draw (access point + >cabling) to 15.4W.

I would try removing any profile of the bravo SSID, show the SSID then try to connect to the network once it appears in the wireless utility. Once connected, go back and hide the SSID.

Turn PC off/on to see if you notice any change.

The PoE injector I get. But the price is like $100 for one. That is like very pricy!

I tried to reboot my pc, and when it booted up, it automaticly connected to the bravo SSID. (tried to disable/enable the NIC, but wasn't enough)
 When it did connect the power bars showed, and that is fine for me. Thanks for your help.

The solution was indirect.
