I own a S2 since mid June 2011. Since Aug 1st, I strangely am unable to send data across any wireless router even though the S2 says it is connected to that wireless access point. I was able to do it till the end of July (last successful access was Jul 30). Even the wireless router at my home where I have used several times via this device is now unsuccessful. To check if the wireless router is at fault, I have connected couple of other devices such as laptop and ipod touch and all are able to transmit. Has anyone else faced a similar issue and has a resolution? Will an Android version upgrade (2.3.4) help? I run 2.3.3.Thanks.
