CM12 theme app crashes

Oneplus One Android 5 Lollipop
Go to setting -apps -all.
Scroll down until you find these 3 apps called Theme chooser, Themes and Themes provider.
Clear the data of each one of them.
Most importantly, please do clear other theme related data.
ALL of them,unless it wouldnt worked. 
Then reboot...

Repeater beállítása

Cél: jelenlegi vezeték nélküli hálózat hatósugarának kiterjesztése egy REPEATER eszközzel.
Példa a felépítésre:

ÚTVÁLASZTÓ (ROUTER) - Internetre kapcsolódó eszköz
STATIKUS CÍM
IP cím pl.: 192.168.1.100
DHCP BE
|
| WLAN ---)))
|
WiFi elosztó - REPEATER
STATIKUS CÍM - DHCP és tűzfal KIKAPCSOLVA

IP cím pl.: 192.168.1.101

GW+DNS is ROUTER IP (192.168.1.100)
|
| WLAN ---)))
|
PC/egyéb kliens
STATIKUS CÍM
IP cím pl.: 192.168.1.1
GW+DNS is ROUTER IP (192.168.1.100)
stb.

FONTOS!
Ugyanazon az alhálózaton kell lenni az eszközöknek, hogy kommunikálni tudjanak!
http://en.wikipedia.org/wiki/Subnetwork

"As it looks Johnny your two devices are on different Subnets, thats why they can't communicate!
You will need to change the IP of the Linksys to 192.168.0.2 for them to be able to communicate. You will also need to disable the DHCP (if it is turned on) on the Linksys.
You can find both of these settings on the Linksys configuration under LAN Settings.
Also if there is a firewall running on the Linksys turning it off will make things easier for you. The D-Link will handle the firewalling for your network!
Turn off the D-Link and set up the Linksys as I described above. When finished the setup save you settings and turn the D-Link back on and you should be fine!
Cheers!"
