Please see the screenshot attached.
Same issue happened again. GPS worked but Internet connection pop-up did not open and e-mail program keeps on closing.
What i did was disabled CSSU-Devel
ran apt-get update/ apt-get upgrade.
Issue was fixed
later installed CSSU-Stable.
The issue started with marble maps. It was showing wrong routes like for less than 30KM distance, it gave around 173KM route. Thought something wrong with GPS then i think most of my checks happened indoors which also was a bad idea.
Marble still got issues i'll have to check in its official thread. Modrana looking good now. I never use Nokia maps

Thank you all of you.
