My new Coby tablet model #MIC1125-4G does not connect to my wireless network which is secured with a WEP key. The tablet connects everywhere else (Starbucks, etc.) and all my computers work in my wireless network. My router is a model #WRVS4400N. So it seems there is nothing wrong with my tablet and there is nothing wrong with my router. Do you know if there is an incompatibility issue?
