Welcome to the weblog of an islander — published at Beachlevel.

After I’ve updated my iPhone to iOS4 last night my Wi-Fi con­nec­tion started to become very wonky. Sometimes I was able to join a network, sometimes not. And even when I was able to suc­cess­fully join one I was prompted to type in the password again, and again, and again.

There seem to be a lot of people out there with the same problem (according to Google and the Apple support forums) and the only sug­ges­tion — which only worked for a few folks — is to “Reset Network Settings” followed by several reboots. That didn’t work for me though.

Since I changed nothing inside of the fleet of WPA2/PSK2 access­points I admister at work this is clearly not a iPhone hardware problem nor a software problem on the accesspoint/router side but a iOS4 software problem. A very odd one I might add.

So here’s the fix (and probably the proof why it’s odd):

If you want to join a Wi-Fi network you usually open the “Settings” app and tap on “Wi-Fi”. Don’t do that, this isn’t helping much (at least not when you encountered Wi-Fi problems — which is probably why you are reading this anyway).

Again, don’t tap on “Wi-Fi” but swipe down a bit and tap on “General”, then tap on “Network”. Now swipe down to the bottom and tap on — yes — “Wi-Fi”.

Surprise surprise, the “long road” Wi-Fi page looks exactly the same as when you enter it via the “short road”, but at least to me, only the long road works for joining networks and storing their passwords.

Let me know if this works for you as well. And Apple, please fix that bug sometime over the next few months.
