Android 4.0.4 Dynamic IP Issue

Trying to connect a A1CS Fusion5 Xtra Android tablet to my WiFi, I was finding it got stuck in a continuous loop: obtaining IP address->saved settings->obtaining IP address->saved settings, and so on.

It seems to be a problem afflicting a lot of Android 4.0.4 devices. I have not been able to find a way to upgrade this tablet yet, but one solution often given is to set a static IP on the tablet. Easier said than done: there is no access to the “advanced settings” for WiFi connections on this tablet; I just can’t see how to do it.

Next thing to try was to set a static IP for the MAC address of the tablet WiFI on my router (which is actually an SME Server, which makes this task very easy). Bingo – the tablet connected immediately with no issues. So the WiFi is not the problem; it is the dynamic IP negotiation (DHCP) that is a problem, and then only when dynamically allocating from a pool of IP addresses. Strangely, the tablet worked on my SME server version 7 a year ago, but is not working on my SME Server v8 (an upgrade) this year. Something in the DHCP protocol has changed, and Android 4.0.4 does not like it.

I just need to set up something similar for my mum on her router, so she can use the tablet at home. Ideally an Android update would be good, but support for older hardware (this tablet is 14 months old, so positively ancient now) from ANY manufacturer these days is non-existent. Moving on from Android 4.1.2 on my Samsung S2 is going to be another battle.

    My ASUS Memo 7 suddenly ceased to operate with Dynamic IPs. It appears to have started with an Android update to 4.2.2. ( Or at least the timing was coincidence.)
    Works fine with static IP’s but it’s mobile use is worthless. Paid a visit to Androids “customer service” site. What a waste…. Does anyone know of a patch, fix, configuration?
