This is in regards to a Samsung i5510

The problem is to do with WiFi networks, the first time the phone connects to a WiFi network it works perfectly but thereafter it just doesn't connect, just gets stuck obtaining an IP address then disables the network.

Didn't find anything searching here but Google searches show this is a common issue, for eg:

Search One

Search Two

I have updated the router firmware and tried setting a static IP for the phone but it still won't connect which is really annoying.

Next thing I will do is set the router to reserve a specific IP address for the phone's mac address then rename the WiFi access point to see if it'll let it connect back up.

Anyone else suffering this issue?
