Wireless no longer working

[Ninja3Kin]

I just installed OS X 10.4.5. During the post-installation, my wireless card was detected and was working. Even after I had booted in to OS X, everything was fine and I was able to browse the web. However, when I rebooted for the first time, my wireless no longer worked. I tried to configure it somehow, but it said an Airport card could not be found everywhere I went.

 

So I ran 'ifconfig' in the terminal, and my device was there... As 'en0' I think - not sure if that was the exact. The only problem was that it's properties weren't set correctly, like essid.

 

Does anyone know what I need to do to get my wireless working again? Maybe I need to edit a configuration file somewhere?

I finally fixed it! Here's what I did:

 

I edited the file /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist.. I found the interface of my wireless adapter, which was "en0" for me, and I replaced "en0" with "en1" in the file. I also changed "0" to "1" further down.

 

Before:

		<dict>
		<key>BSD Name</key>
		<string>en0</string>
		<key>IOBuiltin</key>
		<false/>
		<key>IOInterfaceType</key>
		<integer>6</integer>
		<key>IOInterfaceUnit</key>
		<integer>0</integer>

 

After:

		<dict>
		<key>BSD Name</key>
		<string>en1</string>
		<key>IOBuiltin</key>
		<false/>
		<key>IOInterfaceType</key>
		<integer>6</integer>
		<key>IOInterfaceUnit</key>
		<integer>1</integer>

 

I only edited the first string value, and the second integer value.

 

After editing, I rebooted, and OS X detected I had an airport and I configured it normally in the network settings from there.

sadly...this didn't fix my problem. In fact when i did this, the little wireless meter that is next to the speaker no longer appeared when i changed it to en1

 

when i changed it back to en0 it came back, but it didn't matter because it still doesnt work
