WiFi Connection Issues Still Affecting iOS 4.2.1 for iPad

Early this month we reported that Apple delayed the release of iOS 4.2 due to the Wi-Fi connection issues. Apple even released a second GM build for iPad to address the Wi-Fi issues. Finally, the iOS 4.2.1 went public. But iPad users still report that they experience Wi-Fi problems after upgrading to iOS 4.2.1. Some iPads fail to join a known WiFi network, some connect but connection drops after 5-10 minutes, some don’t drop the connection but are incredibly slow at rendering web pages and, for example, Youtube videos. Though the iOS 4.2.1 offers its users some fixes, including router reboots, resetting the iPad’s network settings and full restore to iOS 4.2.1, they seem not to work. Nevertheless not every an iPad user experiences such problems.
