Perhaps the most widely reported problem after disappearing applications is one in which WiFi connectivity fails after the iPhone OS 2.2 update. Users continue to report these problems with frequency. A sampling of reports from iPhone Atlas readers:
- "Ever since this last update for the iPhone 3G, I've had a problem connecting to ALL WIFI hotspots, including my own secure router at home (linksys router). HELP!! My version is 2.2 (5G77) and modem firmware is 02.28.00 if this helps."
- "I have an iPhone 3g (unjailed) and after the release of firmware 2.2, my iPhone froze and after hard reboot, I just was unable to connect to wifi, whatever the wifi is: protected, open. I tried hard reboot, reinstall, "forget my settings" or what so ever, nothing worked."
- "My iPhone 3G will pickup the right IP address of my router, but I cannot connect to the internet."
- "My iPhone had no issues with finding WiFi networks until I upgraded to 2.2. Now I cannot find any WiFi networks."
In some cases, "forgetting" the currently configured network and then reconfiguring it can resolve the issue. Other potential fixes include:
- Navigate to Settings > Reset and choose "Reset Network Settings"
- Switch the router to WPA2-Personal/AES security settings
- Remove all spaces from the WPA pass phrase
- Remove all security from the router until a stable connection is attained then reconfigure the security
Some users have resorted to a downgrade to iPhone OS 2.1. Apple Discussions poster James DeRosa writes:
"And just another confirmation... I just downgraded to 2.1 on the same phone, same router, same everything.. WiFi is snappy again. Girlfriend's is still 2.2 and WiFi stutters and takes forever. EDGE is actually quicker. Not a bandwidth type of faster, but quicker and more reliable response time."
