Just bought this off ebay, going to give it a try, the seller of my ZT-180 was saying to hook up an wifi extender or wifi repeater in my home because the wifi on this tablet is very low power to save battery life, well I just bought my router a month ago, so I'm not replacing it or buying extenders / repeaters when everything else I have connects and stays connected just fine, will try this little wifi nub you speak of and see if it works for mine, mine is the ZT-180 with the 1030 FW (susposedly the newest model) other then the wifi, I think its a pretty good Ipad knock off. Will report back once I try the wifi adapter. fingers crossed.
