I have the problem with the wireless connection from tablet ifive mini 3gs to mikrotik 951Ui-2HnD. The tablet is connected and a normal working some time - about 15 minutes. After that despite the established connection stops to transmit data. Off/on the wireless network on the tablet helps for some times. Other devices work fine.
Is it tablet based on mtk6592 http://www.ifive.com.cn/product/pc/3-1-13.html
Other devices not disconnected . With routers from another manufacturer, for example, tp-link, this tablet works fine. Perhaps some individual intolerance
