I got a new router, my Odroid N2 with Realtek RTL8192CU Wireless LAN 802.11n USB 2.0 Network Adapter, running CoreElec 9.2.7 connected just fine, then about a day later I had to factory reset my router, because a app got stuck installing, and would not finish, or uninstall. Now my media center seems to act funny with wifi. Some SSID’s will show up, then randomly disappear, when I try to connect, it usually sits at associating, and then eventually says failure. My router is open, and uses mac addresses for security, I have double checked that the mac address for the media center is allowed, I have rebooted the media center multiple times, and it keeps doing this. I have just ordered a new USB wifi specifically for Odroid, but I am doubting that, that is the problem. I am starting to think it might be software related, but since I can not SSH into the machine to check settings on console, I am lost as to what to do. Can someone point me in a direction to start to diagnose this problem?
EDIT: It would take me at least a week to get a UART cable also.
