Thanks to iOS 5, some users lose WiFi connectivity

Of all the enhancements to discover in Apple's iOS 5 upgrade, it seems that an unforeseen monster may have snuck its way into the release. We're now reading through a handful of user complaints about losing WiFi after taking the plunge, with most replies mentioning intermittent connectivity and / or a significant loss in signal strength. The issue remains unconfirmed by Apple, but it appears to span across a number of devices, including the iPhone 4S, 4 and 3GS, along with the iPad (and possibly, the iPod Touch). By troubleshooting, one user was able to resolve the problem by reverting to iOS 4.3, then cause it to manifest -- once again -- by upgrading to iOS 5. The recent iOS 5.0.1 update certainly hasn't fixed the matter, either. Could these reports be an unfortunate series of unrelated events, or is there something larger at play? Sound off about your experience with WiFi and iOS 5 in the comments below.
