As more consumers tend to get their hands on an iPhone 5, more issues seem to be surfacing with the device. New reports are coming in of customers having a problem with the iPhone 5ís Wi-Fi connectivity. Many users are continually complaining about slow to no Wi-Fi connectivity while others are reporting simply slower-than-normal activity on the device. Users have been able to isolate their problem to when they connect to WPA2 encrypted Wi-Fi routers and found that moving to the much less secure WEP encryption or being unprotected can help resolve the issue for now.
Since most Apple stores have unprotected Wi-Fi, the issue may not show up at all in-store. While some users said getting a replacement from Apple fixed the issue, others are reporting no success after getting a replacement unit either. It should be noted that there may be multiple Wi-Fi related issues that could be affecting users. Threads on the Apple discussion forums reflect the same issues among many customers.
One Apple forum goer received confirmation from AppleCare that Apple seems to be aware of the issue but does not have a resolution available yet. He mentioned the following:
Just spoke with iPhone AppleCare and they are definitely aware of the problem and Apple engineers are working on it. I asked if it was hardware or software related and she said the WPA2 issue seems to be software based and the non-connecting issue may be hardware based, but that they are still trying to identify the cause.
Have any of you experienced any issues with your Wi-Fi connectivity on your iPhone 5?
