I'm having the same problems, the tablet just goes round in a circle attempting to connect to my Sky Netgear router, authenticating then either fails, says not in range, or connects then immediately drops the connection again. No other devices having issues on my network, and the tablet connects fine to other wifi networks.
I emailed Storage Options support, not much help beyond suggesting a factory reset or returning the device to eBuyer. Unfortunately it's 3 months old now and I've lost the USB cable so that's probably not an option.
I'm running Android 4.0.3 so maybe worth trying an update to 4.0.4 although that sounds pretty painful judging by the forum guides.
Not particularly impressed with the problem, the support or the general performance of the tablet, wish I'd held on for other devices in the price range to come on the market
