Hello Phoxx,
I do not suspect a problem with image 5308, it is operating fine for me. The steps you have followed seem reasonably correct as far as my memory serves me. However, I have found the AZBox to be a little finicky at times when setting up the WiFi connection. Obviously, the first item to address is to ensure that all the IP addressing parameters (numbers) are correct. You know this, but you should double check to be certain.
Beyond the obvious, I have occasionally found it necessary to toggle between WIRED and WiFi setups to get the WiFi operational. Setting up the WIRED network is more forgiving, so if you have an ethernet cable and can connect to your router or modem direct, that will get the connection to the internet established. Then you may switch the option over to WiFi and reset the connection from scratch. Once the connection parameters have been set up, instead of testing the connection, I do a FULL hard reboot (power down completely and then power back up). Then I go into the menus and check the connection speed and the time synchronization feature via internet. It always seems to work fine with a little persuasion this way.
I think I covered this in my sticky and I am sure that StarGaze quoted me on most of this in the A-Z Manual. The main thing that I have found is that sometimes the hard reboot is necessary to kick start the WiFi. The standard reboot doesn't always seem to get it going.
