hello. I just got your #2 issue, when select Realtime Data - wireless. Loading animation and browser hangs. But I have disabled both wi-fi SSID.
After 10-15 sec I just deleted path in address bar, leaving only ip address of router and press enter. And GUI are back to normal. tried two times.
RUTXR1, FW 00.07, clean install via bootloader, no any services, one not working ipsec tunnel and 4G LTE SIM.
