Fixing Your Airport Woes

Ben at MacFixIt sent along these WiFi tips after I complained about poor WiFi performance after installing Mac OS 10.4.8 and AirPort Update 2006-001 (version 1.0). So far, removing Coconut WiFi seems to have fixed the problem.
– Try changing the wireless specification mode used by your router (or base station). Try switching from 802.11g to 802.11b, for instance.
– Disabling coconutWiFi — an application displays you a small aqua-bubble at the top of your screen which indicates whether you’re in range of a wireless network or not — may resolve an issue where AirPort connections toggle between normal speed and dismal speed.
– Delete all stored wireless networks from the Preferred networks list, then add back any used networks via the following process:
Open System Preferences
Go to the “Network’ pane
Select “AirPort” from the “Show:” menu
Click on the “AirPort” tab
Select “Preferred networks” from the “By default, join:” menu
Delete any networks from the list (using the “-” button) that you do not regularly use
Click the “Apply Now” button
– Reset the PMU.
– Turn off the Mac OS X Firewall (in the Sharing pane of System Preferences) resolved the issues in his case.
– In some cases, deleting the AirPort preferences can resolve the issue:
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
If any of these solutions work for you, post your results in the comments below.
