Okay, this may be a few different things put together.
I am currently roaming, ie. not on my home mobile provider.
I try to keep mobile data disabled when I don't need it
I have access to WiFi in my room, but for some reason the connection is unstable & usually only last 30-60 seconds. Disabling & enabling again restores the connection for a similar amount of time.
I have access to a couple of other devices, and for these WiFi works fine, no question. They are not as useful as my Cosmo however
WiFi is 'N', seems to be a fairly aged LinkSys AP that I have no access to.
Any suggestions please?
