my problem is, my device has the capabilities to launch the wifi hotspot/wifi tether...but during the authentication process, my android tells me that, ...' that the NETWORK is having problems 'authenticating the server' , 'try again later.'..pls. help me understand how and why a network carrier can influence the performance and capabilities of ANY device. i would like my phone to perform the same tasks and features as smoothly today, as it certainly Must-Have done last week.
