Every new firmware release tends to have some bugs and teething issues and iOS 8 is no different. If you have just recently grabbed iOS 8 for your iPhone, iPad or iPod touch, you may have encountered some wi-fi related issues. In fact, it is clear from the Apple Support forums, that a lot of users have been affected by this and a number of other problems. Until Apple makes the necessary bug fixes there isn't that much that you can do.
The roll-out of iOS 8 has passed with very little incident and has been well received. It hasn't however completely avoided the headlines and iPhone 4s users have been strongly advised against updating. There have been several key functionality related bugs tarnishing the fluidity of iOS 8 on the iPhone 4s and now it seems that there are some wi-fi issues being reported by many users.
What is happening, is that wi-fi seems to struggle with basic connectivity and dropped connections are occurring on a wide range of iOS running products. A number of affected users have contacted Apple Support about this and the general message seems to be to do a restore. One user found that while restoring to new remedied the problems, they soon returned when a backup was applied, suggesting that the problem lies within iOS 8's compatibility with backups rather than the software itself.
Another issue that has been causing problems once again is the battery drain and it does appear that Apple's new iOS 8 has a few kinks that still need to be ironed out. Hopefully this will happen very quickly and if you haven't already updated to the latest software, you might want to hold off until all the little bugs have been resolved. If you have been experiencing any bugs in iOS 8, why not let us know about them in the comments.
