I've had this issue where the signal just cuts out ever since I started using the white wifi router several months ago. I want to be able to see the Wifi Portal but the website access just doesn't work for it.
Now my LTE has clearly been cut OFF.
Usually I would just unplug all the connections e.g. power supply and Ethernet cables wait for a minute then plug and turn it back on. That would do the trick sometimes but not this time.
