I just purchased 2 COBY Kyros MID9042-8 and have a problem with the WiFi Range. I am not able to get further than 15 feet away from my router and still connect to the router. I get a message "not in range" however I show good signal strength. I am assuming it is the tablets capability since I have no issues with other computers connecting from anywhere in my home. Am I really stuck with having to be within a 15 foot radius of the router????
