Over the last few months I have noticed that in my room at home (Mosgiel, Dunedin) my phone will loose connectivity to 2D and never gain it back until the phone is rebooted. I work in central Dunedin and have no issues throughout the day and when I am connected to the network at home it is a 5 bar location.

Using a rooted Ideos X5 (running Android 2.3.7 - Miui-111250) which has just turned 2 years old.

Any ideas?
Thanks
