I have access to a WiFi-network with SSID broadcast disabled and protected using WEP. It works great to connect to the WLAN-network manually using the iPhone, but I have to do it manually every time. The iPhone doesn't remember the network and password, why is that? I'm using iPhone OS 3.0.1 on my 3GS.

Just so you know: hiding a wireless network name does not help to improve security --… (and WEP is not secure either). – Arjan Oct 22 '09 at 16:32
Yes I'm aware of the security limitations. – salle Oct 22 '09 at 17:32

Try Resetting all Network Settings, it usually works. Alternatively, try using a $ before your password, i.e., enter $password.

Just out of curiosity, why the dollar sign? What does that mean? – Josh Hunt Apr 18 '11 at 17:01

It is not related to the iPhone only. It is not implemented by Apple in the Mac OS X as well. See: Automatically Connecting to Hidden SSID WiFi Network Not that it helps you, but at least you can see you are not the only one :)
