Hi. My Sony Tablet S wifi has always worked perfectly, for several months now. Until today. All of the sudden it disconnects me from the network but leaves my wifi on. So I try to reconnect but it just going Connected...Obtaining IP address...Disconnected...Connected...Obtaining IP address...Disconnected... over and over again without ever establishing a successful connection. I next tried turning the wifi on/off as well as turning the tablet itself on/off but all without success. At this point my flight was taxiing to the runaway and I left it turned off, figuring maybe the local wifi had just gone buggy. But sure enough the next airport, one I am at every month, the same wifi issue appears. I powered up my laptop but it connected fine. Next I tried to connect my tablet to my laptop. However it never even appears as a drive under Computer as it always has before. It would appear that the USB connect has gone out at the same time as the wifi....huh?!? Third airport, my hometown. Still no results. And now, even here at home on my primary network the wifi just cycles endlessly without connecting -- plus the tablet still fails to connect to the desktop via USB. That's four reliable and working networks and two computers that have now verified these dual errors. And I have no idea what to do now. Once again, this tablet was fine and working one minute -- I was sending emails -- and then BOOM! it disconnected me and all these issues arose. I cannot even access the Play Store for any updates or upgrades or apps. However the SD card slot still appears to work. Have any thoughts or ideas? Has this ever happened to you? Thanks and best wishes for the new week!
