I have a raspberry Pi3B with a 2.5A powersupply, brand new out of the box. Have installed OSMC to a 8GIG SD card and added the wireless network while installing via my laptop to the SD card. I only have WiFi so no other ways to connect to the raspberry Pi. The problem I am facing is the following. After doing all steps to install is says there is no network. Then I go to the OSMC settings to network. Now it finds 2 of the 10 WiFi signals that are available in my house. I connect to one and it does not connect. Then the SSID just dissapears from the wireless connection page. I can now never get it back. I tried versions 2018.03-2 2018.02-1 and 2018.01-1. Every time the same problem. Tried a different power adapter but that gives problems with the bolt in the right hand corner (its a 2A so thats logic). Cannot create log for there is no connection to make to the Pi. Is my Pi broken or can you advise on a way to go forward?
