iOS 6.1.3 seems to be plagued by numerous issues, including battery drainage and, most recently, Wi-Fi problems. A considerable number of customers on Apple Support Communities say their wireless connection is poor, or doesn’t work at all after installing the new update.
There are multiple threads discussing what appears to be a bug that affects wireless connections on devices with iOS 6.1.3 installed.
While Apple is yet to confirm that this is indeed an issue, here’s what a handful of customers are saying on one such forum thread.
“Hi! I just got a new Iphone 4s back from repair, a new replacment [sic] phone. So I updated the hardware to the new IOS 6.1.3 and after that I cant activate my WIFI, the WIFI button is greyed, so the WIFI is unavailable.”
Another user says, “I have the same problem that the creator of this [post] has.”
“The wifi and bluetooth has been greyed, its like I need to activate it in rectrictions [sic]. It happend [sic] right after updating to 6.1.3 and it have done this to two of my 4 iphones,” this person writes.
A KB article on Apple Support details similar symptoms.
“In rare instances, your iPhone, iPad, or iPod touch may be unable to enable Wi-Fi or Bluetooth in Settings. When this occurs, you will see the following symptoms:
- Unable to turn Wi-Fi or Bluetooth on or off because the setting is grayed out or dim.
- Missing Wi-Fi or Bluetooth MAC Address missing or displaying all zeros in Settings > General > About.”
A separate forum thread on Apple Support Communities may also provide indication that the issue isn’t, in fact, new.
Moreover, it may not be an actual problem inherent to any iOS software update, but rather a typical behavior on behalf of your iDevice whenever the wireless settings get messed up.
