MacBook Pro can't see Airport network but three other macs in house can

Have you tried deleting the wireless network name (SSID) from Preferred Networks in your Network configuration, and then re-entering it again?

Also, have you tried adding a new user account for testing purposes in case there is some file or setting behind your user account that is causing the problem?

Since you've tried various locations in the house, I don't think that changing the wireless channel will help.

Quick update. I must admit to being quite confused now. Last night before I went to bed, I turned off my modem (which I do every night). The LED on the AEBS was flashing amber, which is what I expected. I didn't turn it back on until probably a couple of hours ago. For kicks, I tried Airport Utility and much to my surprise, Utility could see my AEBS. I really didn't do anything so I can't really pass along any tips to help anyone out!!! I did exit Airport Utility and launched the app again and sure enough, there is my AEBS!! I haven't updated any software or made any changes since my last post so I really don't understand what went wrong. If anything changes, I will repost.

Did you perchance purchase the MacBook Pro in the US or in a country that doesn't support wireless channels above 11?

If you did, and your home wireless router is configured or otherwise set for channel 12 or 13, then you would not be able to make a wireless connection.

My Airport Extreme has worked flawlessly with my MBP forever; or at least until the most recent update.

I seriously doubt that this is a matter of country of manufacture, or channel, or location in the dwelling. I say this because I'm now typing this using IE in XP via BootCamp, because I can't print to my wireless printer from OS X. And, because the Aiport Utility in XP still sees the Airport,...because I have yet to run the latest Airport updates for Windows?

And, it isn't that OS X doesn't see the Airport. I have great wireless access. It's just the Utility that doesn't see the Airport.

Why??

Add me to the list of those puzzled by this behavior.
Old PowerBook G4 connects to, can see and configure Airport Express with no problem. PowerBook sees AE speakers in iTunes when connected as AirTunes.
Brand new MacBook Pro can connect to AE with no problem but cannot see it in Airport Utility or see it when connected via iTunes.
I believe same problem preventing iPhone from syncing via WiFi on Remote and 1Password from App Store.
iPhone sees MBP but MBP cannot see iPhone.
Naturally, PowerBook can see iPhone as Remote in iTunes.
Strange indeed.

My previous response was directed to windyhousesjim. Your problem seems to be something entirely different.

My apologies. I misunderstood.

I have the same problem.
My macbook is happy.
My pc laptop is happy.
My imac can't see the airport network at all.
Help!

Update #2: Today my MBP sees the Airport, but will not connect; at all. Now it's not just an AU problem. But, the BootCamp XP partition connects just fine (ergo this post).

Thank God for Windows?! (Somebody please shoot me.)

Next Mac update?? Please.

My macbook only connects during the day, at night it can't connect, it doesn't see the airport network, and when it sees the network it gives connection time error... I know it sounds strange, but it's what happens...

Could it be the DHCP lease time? By default it's for 4 hours, I think think that my problem could be than after that period of time it can't connect... Now I have put 30 days to try if it works fine... I'll tell you what happens...

My wireless problem related to this topic is that my 2 MacBook Pros will just drop local network connections at random, but happening at least 2 or 3 times daily. When this happens, they both maintain wireless access to the Internet but loose wireless visibility to any server or device on my local network (i.e. Network Printer, Mac G5 Wired Desktop, Time-Capsule).

Like others who have posted to this topic, it seemed to start happening after the 7.3.2 firmware update (which I didn't initiate, just updated on its own). Access to my Time-Capsule from my G5 desktop shows no problems, as it is wired directly into it. I also have no wireless connectivity problems during these outage periods from the 2 iPhones I own.

Current remedies for my wireless MacBook Pros have been:

* Select different broadcast channel (automatic does this but not sure if it's helping)
* Reset the Time-Capsule from the wired G5 Mac
* Power cycle the Time-Capsule
* Turning Airport off and then on again to reconnect to Time-Capsule home network

All of these measures work for a few hours and then network/bonjour services drop again for the wireless devices. Any help would surely be appreciated...

The Automatic wireless channel selection only takes into account other Wi-Fi networks and not cordless phones and other types of potential wireless interference.

For this reason, I think it is best to experiment by selecting various wireless channels manually.

I had similar problems - network accessible but Airport Utility couldn't see the Extreme or the Express. The network disk was also unavailable. It turns out that the Apple firewall on my PowerBook was abnormally denying configd and mDNSResponder data from the basestations.

Look under System Preferences -> Security -> Firewall -> Advanced -> Open Log to see if yours is doing the same.

Turning off the firewall "fixes" the problem. Otherwise what worked for me was to reset the Power Management Unit, then to add /usr/sbin/mDNSResponder, /usr/sbin/configd, and /usr/sbin/nmbd to "Accept incoming services" in the firewall. (Beware - resetting the PMU will lose the date and time as well as the name and password of your wireless network)
