Reposted from Comments for visibility. "Hi, Have you inserted the SIM card correctly? If so, have you tried your SIM in another network compatible mobile phone and see if it works? Have you tried another known working network compatible SIM card in your phone and see if it works?" ---------------------------------------------------------- My Thoughts: Your phone may be network locked perso locked or banned from the carrier your attempting to use. Call your carrier to check your IMEI. Also, You may want to try gently wiping down the sim card with alcohol. (Do not put it into the phone until it is dry. You have been warned.)
Replace the Digitizer. If you're still getting a picture then the problem lies within the Digitizer. I would recommend that you purchase the glass and digitizer already put together as its hard as a motherfu**er to adhere them.
I can't exactly tell you why. Sometimes 2 programs start crashing one another on android. Just do a factory reset and you should be fine.

If you achieve your normal speed using ethernet then you are most likely having a range problem. 2. Try manually forgetting the network from your computer. In your screenshot, it looks as if there is some type of error in the way your computer attempts to access the router. Forgetting the network and connecting again will force your computer to download those "settings" again. 3. Try running your computer directly into the modem (unplug the ethernet cable running into your router and connect your PC directly.) and see if you are achieving the speed you desire. If number 1 and 2 don't work and this does, You will need to purchase a new router. 4. Try using another device for the steps listed above. (If possible, use a friends PC to test it as the device has never connected to the network before.) If using another device fixes the problem you might be able to fix the problem by factory...
