Connect to airport 'invalid password'

[drtpdee]

I have a network set up in which the primary access is via a cable modem connect to an AIrport Extreme. I also have an Airport Express connected as part of this network for Airtunes purposes. I typically connect wirelessly via a new iMac, no problems. I want my Powerbook G4 to connect as well (via its Airport Card). However, when I attempt to access the network and enter the password that I just created, it gives me an error stating 'invalid password'. What's going on? Also, when I set up my Airport Express, it wouldn't update the firmware despite saying that update was successful. It's 6.0 and won't go to 6.3

Have you made sure the password you're inputting is in the right case? i.e. upper case or lower, or a combination of both, whichever you originally set it up with.

It is.

I've found that when there is a lot of interference from other wireless devices, especially other wireless routers, airport can't seem to connect well and when it does it asks for a password and then gives the "invalid password" response. I had that happen recently and the only thing that worked was changing the channel from 1 to 11 (everyone else around is on the default, 6). So I can only surmise that someone else who just moved in was interfering with my router because it happened all of a sudden (apartments suck for wireless connectivity, trust me).

I don't know if that's your problem but just remember that it could be a symptom of another problem.

how do you "change the channel from 1 to 11"?

Thanks for this thread. I had the exact same problem -- invalid password, when the computer was 4 physical feet and two thin sheets of drywall from a good router.

how do you "change the channel from 1 to 11"?

Kristopher (or presumably anyone else who finds this through Google) -- the channel change is not on your Mac -- it's within your router itself. The way to do it will vary with the router. Most routers will have a Web page interface for administration. Look for something like Wireless settings.

The "best" channel will depend on what your neighbors are using, but you might try 1, 6 or 11. My wife noticed her iBook connected faster than it had been, too, after we changed the channel -- interference will do that! =)

Possible solution to "invalid password" problem on airport

I had this exact same problem. After going through every suggestion here and elsewhere, and trying to reconfigure the network settings, nothing worked. Here is what did work for me:

I deleted all the network profiles in my network settings. Then I did a factory reset on my AirPort Express (google it for instructions), and set up the airport with a new network as if it were brand new. Voila!

Wait! A G4 PowerBook...?

What OS are you running?

Which security profile, WEP, WPA or what is set up on the AirPort?

You may only be able to use WEP depending on your PowerBook's OS.

Moving closer to Time Capsule solved "Invalid Password"

All of a sudden, my wife's MacBook Pro lost its Internet connection. When I tried to log back in to our usual WPA2 wi-fi router, I kept getting "Invalid password" errors even though the password was correct. I could log on to a neighbor's unprotected wi-fi without problem. So then I tried putting the laptop right next to the Time Capsule / Router and "Voila!" it logged in just fine. So there might be something to this "interference" idea. I was able to then bring the laptop elsewhere in the house and not have a problem. Strange. Maybe it's just because it's Halloween!

Wireless Interference Causing "Invalid Password" Error on Wifi

I have all Macs in my house and have never had a problem with my Internet connectivity until today. I'm a Technical Support Specialist and consider myself pretty computer savvy.. but I have to give props for this suggestion because the interference issue was exactly my problem although I still don't understand why this would give an "invalid password" error on the wifi connection.

All my Apple computers were connecting wirelessly without a problem except for my MacBook Pro. I could not figure out why it was telling me the wifi password was incorrect when it had been working fine and all my other devices were obviously connected without a problem. I stumbled across this solution while researching the issue, and it hit me.. I recently installed a wireless TV tuner in my living room (which is the room I was in) that sends a wireless infrared signal to a receiver in my kitchen. I unplugged the wireless tuner and my Wifi immediately connected with no error.

Thank you for the suggestion!
