Since I upgraded to 10.6.5, my MacBook Pro (Early 2006) cannot connect to my USR9110 (802.11 g) access point. 
From 10.6 on, there's been always troubles when resuming after sleep, but now even at startup the connection goes timeout.

All other devices (an iPhone,an iPad and a MacBook Pro (Late 2006) with 10.5) work perfectly.

I tried rebooting, changing  the wifi channel, updating the access point firmware, turning on and off airport, resetting the SMC, switching to WEP, switching to WPA, switching to unencrypted. Nothing changes, connection timeout.

    Try the steps in the blog How I fixed my dropping wireless Airport connection problem in Snow Leopard to see if any of these steps work.

    That's a helpful resource, but some items don't apply.

    I'm trying to connect to my university secure wireless network, so I can't exactly change channels on the router.

    This is definitely a 10.6.5 update problem. I was using the wireless network, even as I was downloading the 10.6.5 update. After restart from the update, that's when the wifi problems appeared.

    The non-geek way to try to reset your Airport card.

    1. Quit All Programs!
    2. Open System Preferences->Network and Highlight the Airport card. Then TURN OFF the Airport card!
    3. In the lefthand pane (while the Airport card is still highlighted) and click on the - button.
    4. Don't Panic!
    5. Reboot immediately (Don't skip this step)!
    6. Upon the restart open again System Preferences->Network and click the + button and re-add the Airport card.
    7. Then in the right hand of the Network pane click on the 'Apply' button.
    8. Now put in you wireless settings (from the Network pane) and try to rejoin the network. If this is successful hit the 'Apply' button (in the Network pane still).

    This is the non-geek way to reset the airport drivers in OS X. See if this helps, Good Luck.

    Thanks for info. It worked great. I did find however after I uninstalled airport and reinstalled it, the system tray was not reflecting the status the System Preferences reflected. I had to give an addition reboot after reinstalling Airport. After the second reboot the system tray correctly reflected the status and I was able to rejoin my network.

    Having the same problems here. Airport drops connection randomly. Tried reconfiguring connection settings, re-adding airport to network settings, resetting SMC, rebooting cable modem and wifi router, changing airport connection channel, security settings, network name, rebooting mac several times. Have tried two different routers. Router A: 1st gen Time Capsule 500gb (20ft away), started with a spotty connection almost immediately after updating to 10.6.5, and now when attempting to connect with TC network name will not even show under airport. Like it's gotten worse. Router B: super old Dlink (5 ft away), freshly reset, was spotty earlier today, and now seems to have held a connection for a record 22 minutes.
    So, I am really confused. Anyone having these problems try something I haven't? Please post. Iv'e run out of ideas aside from tethering my iphone or saying goodbye to my TC and security encryptions.

    I just helped another person with the tip of repairing permissions. Specially after an OS upgrade.

    Repair Permissions:
    * Open Disk Utility, located at /Applications/Utilities/Disk Utility
    * Select your startup disk on the left of the Disk Utility window
    * Select First Aid from the tabs
    * Click the "Repair Disk Permissions" button

    Post back if this or any tip works for you so we can help others.

    Thanks for that tip. That's something that I hadn't thought about. But it definitly helps after OS updates. Started repair. Says it'll take 9 minutes.

    Time capsule connection is a bit more stable after renaming it. Though not a smooth as before update. I'll post back after the permissions are fixed.

    Same here... I got a Mac Mini from late 2007. Since install of the 10.6.5 update yesterday, I have very high ping times (1-10s!) or even loss via WLAN...

    I've tried the repair permissions and reinstall AirPort tricks, but no luck. :-/

    Any further Hints?

    Is Apple aware of this 10.6.5 bug, yet? Are they already working on it? Is there some kind of status page?

    I have had a solid connection to the Time Capsule router all morning with expected speed, up and down. I don't wanna call this solved for me because I still had disconnects and airport wonkiness after repairing permissions last night. But, today is a different day, I guess. So far, so good. I have no idea what to suggest, as I have tried so many things. Will report back if things go south again. Thanks everyone for your help/suggestions!
