According to ReadWriteWeb, iPhone and iPad users are reporting Wi-Fi connectivity issues after upgrading iOS 4.3.3 that was released by Apple last week to fix the location tracking bug.
As RWW points out, when iPad 1 was launched last year, users had reported similar Wi-Fi connectivity issues but this time it looks like it is also affecting iPhone users.
After updating my iPad to iOS version 4.3.3, I discovered this problem had again resurfaced, but it was even worse than before. My connection wouldn't just drop after the iPad went to sleep, as it had in the past, it would lose the connection when I was actively using the device, even while surfing the Web.
She reports that users are reporting the following Wi-FI connectivity issues on Apple’s discussion forum:
iPhone 4 says it connects to the Wi-Fi network, but the Wi-Fi icon never appears
Wi-Fi keeps disconnecting and reconnecting on its own
Can no longer use Wi-Fi at all unless within close proximity to the router
Can't connect to Wi-Fi at all on device running 4.3.3, but devices running 4.3.1 have no trouble on same network
Wi-Fi won't work, and resetting network settings doesn't fix
Wi-Fi shows signal, but device can't connect to the Internet
If you’re facing any of these issues, you can follow these tips to see if one of them resolves the issue until Apple releases an iOS software update to fix the issue:
Basic Troubleshooting:
Launch Settings app
Tap Wi-Fi
Turn Wi-Fi toggle off and then on again
If this doesn't work then try to renew IP address, which may be required if you are using a larger wireless network.
Renew IP Address:
Launch Settings app
Tap on the Wi-Fi network that you connect to from the list
Scroll down and tap on the Renew Lease button
If this doesn’t resolve the issue, try establishing a fresh connection with the Wi-Fi network by using the Forget This Network option. Please note that this will clear your current Wi-Fi network settings, including saved Wi-Fi passwords.
Forget This Network:
Launch Settings app
Tap on the Wi-Fi network that you connect to from the list
Tap on the Forget This Network button
You will be prompted with a message that your iOS device will stop automatically joining this network. Tap on the Forget button.
Go back to the list of Wi-Fi networks, try to locate and join the Wi-Fi network again.
If this doesn’t help try restarting your iOS device.
Restart iOS Device:
Press and hold the Sleep/Wake button until "slide to power off" slider appears. Slide your finger across the slider and iOS device will turn off after a few moments.
Turn iOS device on by pressing and holding the Sleep/Wake button until the Apple logo appears.
If restarting your iOS device doesn’t resolve the problem then reset all network settings. Please note that this will clear your current cellular and Wi-Fi network settings, including saved networks, Wi-Fi passwords, and VPN settings.
Reset Network Settings:
Launch Settings app
Tap General
Scroll to the bottom of the screen and tap on Reset
Tap Reset Network Settings
When the device restarts, try to locate and join the Wi-Fi network again.
