When I set up this computer I connected to my wifi router at the other end of the house, but due to the distance I got poor connectivity and performance. So I purchased a wifi repeater and positioned it nearer to this computer. I disconnected from the router and connected to the new repeater without issue, and get good performance. However, whenever I turn-off the computer and then later turn it back on, or restart the computer, it always connects to the router instead of the repeater. I can disconnect from the router, but it won't automatically connect to the repeater (despite having checked the "connect automatically" box), and despite showing the WPA2-Personal password in the wifi profile for the repeater it requires me to mannually enter it in order to connect the repeater. I've tried deleting the router profile in the "manage wifi connections" dialog box, but it seems to automatically come back by itself. Any suggestions on how to automatically connect to the repeater, preferentially over any other wifi connections, and not have to manually enter the password every time?
