I have Xperia neo MT15i

and is now working fine for the wireless on my laptop

Has anyone else had this problem and know how to fix it? 

Thanks  a lot...

I suggest you forget the connection and restart the handset and trying to reconnect the device, if this fails, simply restart the router and try connect from that point.

Let me know how you get on.
