How do I fix iPhone Wi-Fi connection problems?
Some users have reported issues with slow speeds or trouble connecting to Wi-Fi networks with iPhone OS 3.0 and later firmware. iPhone owners who have jailbroken and/or unlocked their iPhones using blackra1n and blacksn0w have also reported problems.
These problems include the inability to connect to Wi-Fi, 3G and/or Edge, lack of push notifications and issues with the YouTube application. Fortunately there are several fixes you can try to correct these data issues on your iPhone:
1. Reset network settings. Touch Settings -> General -> Reset -> Reset Network Settings.
2. Still having problems? Touch Settings -> General -> Reset -> Reset All Settings. Warning: You will lose all of your preferences.3. For YouTube problems on jailbroken iPhones try installing youtubeFix from Cydia or another package installer.
4. Restore your iPhone as a new phone. This is a slow and tedious process but will reset your iPhone as if it was new from the factory. Although this should fix all of the above issues, you will have to reload your contacts and media onto the iPhone from the computer manually. To restore:

2. Router compatibility issues could mean that WPA2 Personal W-Fi security is causing the problem. Switching to WEP security or removing password security altogether can improve Wi-Fi speeds and connectivity.
