my FP2 with most recent software update (1.2.8) seems to have troubles connecting to my wifi-hotspot (which leads to a closed LAN instead of the internet).
At first I connected and it just worked. Then I moved around, lost connection and tried to reconnect as soon as the signal was strong enough again. But I didn't succeed (not even after a reboot - rebooting the accesspoint solved the problem until I loose wifi signal again; rebooting the AP isn't necessary with other smartphones).
Then I found out that the wifi-selection tool behaves strange in several ways. Sometimes it tells me that I'm connected but I am definitely not. When I open the advanced dialog I see that it's oscillating between "connection will be established..." and "connection saved" all the time.
Another minor problem is that the advanced wifi-dialog is hard to tap because the buttons are opened behind the main-UI-buttons (dunno what's their name), see this screenshot:
Another issue in this cause is that the FP2 tries to look up for system-updates continuously while I'm connected to the non-internet-hotspot and I can't find a way to stop it from trying.
Aaaand last but not least another network related issue: The mobile connection symbol on top of the screen tells me that my mobile connection is edge, 3g (btw the 3g-symbol is of a lower resolution than the other mode's symbols), hdspa, hdspa+, alternating in a ~2-3sec. interval all the time. It's changing really fast and I haven't experienced this with my former smartphones on this exact location. I have suspect this behaviour might be linked to the fact that the battery-performance of my FP2 is really poor (about half of the standby time I had with my previous phone - Z3 compact).
It'd be nice if someone could help me with these problems. Otherwise consider this posting as some kind of bugreport.
