Over the last days, the battery of my Lumia 920 was empty much faster than i was used to. Usually it lasted y couple of days, but now it's empty after 1 day.

I found the right hints here: http://answers.microsoft.com/en-us/winphone/forum/wp8-wpupdate/lumia-920-battery-issues/94655503-118c-4dfe-b433-08c23b8140c6
I fixed it by disabled a couple of background tasks. I also found out, that some of those Background tasks were added by recently installed apps.
Go to Settings->Apps->Background Tasks to see the list of apps that work in the background and choose the ones the disable.

Windows Phone 8 Lumia 920 does not connect to company / university WLAN any more. Certificate issue.
I had my Lumia 920 WP8 phone connected to my company / university WLAN at KIT (wkit-802.1x) for months without issues. A few days ago, it started to refuse to connect to the WLAN. It kept asking my for username and passwort and then just told me "Anmeldung nicht möglich" (german). I think the error message in english could be something like "Cannot connect" or "Could not connect to WLAN".
How-i-fixed-it:
The Problem seems to be caused by an issue with the root certificate the Network uses (Deutsche Telekom Root CA 2). I downloaded the certificate again as described on my university WLAN help page, sent it to myself by email and opened it on my phone. WP8 asked me to install the certificate and i confirmed.
After that, i tried to connect to WLAN again and it works!

Windows 8 Crash / BlueScreen / BSOD using Internet Connection Sharing /Tethering with Nokia Lumia 920 WP8 smartphone
Today i used the Internet sharing function on my Nokia Lumia 920 WP8 phone to browse the web from my Windows 8 laptop computer (Dell M1330, Windows 8 64bit).
A few seconds after opening the Internet Explorer 10, my PC showed the Blue Screen Error BSOD (The error is Driver_IRQL_Not_Less_Or_Equal, caused by netwlv64.sys) and rebooted. This was repeatable, rebooting both devices did not help.

I found the right hint here:

I'm just citing this solution here:
Reboot, and before you connect to the Lumia 920 WLAN (or before it crashes), view the properties of the wireless connection. Click Advanced, and enable Federal Information Processing Standards (FIPS) for the connection. That worked for me and i did not see the BSOD again.
