They are reporting that after upgrading to iPhone OS 3.0, their iPhone either cannot maintain a Wi-Fi connection or it doesn't download data once it is connected.
User Gibbons was the first to report the issue back in June 18th, a day after iPhone OS 3.0 was released:
Just thought I'd see if anyone else is having the same strange problem with the WiFi on their iPhone after the 3.0 update.
Essentially, WiFi works fine after the phone has been freshly booted
(i.e. right after a restart) – however, once it has put itself into
standby mode it will no longer download data over a WiFi connection
after the phone is turned on again. It remains able to find the WiFi
network, but simply refuses to download data over it.
Have tried restarting my phone and changing the WiFi security from WPA to WEP, but to no avail…
iPhone users are still reporting issues with their Wi-Fi after upgrading to iPhone OS 3.0 even today, more than 2 months after iPhone OS 3.0 was released. User nhTroy reported of a similar problem:
I have been experiencing wifi trouble as well. Just installed 3.0.1 on my 3G iPhone with no luck.
Trouble started not long after 3.0 update. I watched as the signal from
my home wifi network got weaker. Soon I could not detect any networks
where I used to see 5 or 6.
I have tried nearly every suggestion on this board with no change. Next
step is to get an "expert" on the phone I guess, although sounds like
the only solution is to go and get a replacement.
The issue seems to be affecting many iPhone users as the Apple Discussion thread is currently on the 44th page.
Based on our past experience with Wi-Fi connectivity issues, you can try some of these potential fixes If you are facing this issue:
- Turn Wi-Fi "Off" then "On" in Settings.
- “Forget” the currently configured connection and allow it to reconfigure.
- Switch the router to WPA2.
- Remove all spaces from the WPA pass phrase.
- Remove all security from the router until a stable connection is attained then reconfigure the security.
If the above tips haven't helped in solving the problem then we would recommend you to visit the local Apple Store rather than waiting for Apple to fix it in the next version of iPhone OS.
