Recently moved into a lennar home, setup att fiber. Theres connection through the wired connection and wireless connection but it is very slow. The speeds are showing upwards of 500+ but when browsing online, clicking on websites it never really load, sometimes it gives an error saying it (failure to load because it took too long). I setup  the two aps through the unleashed app, I noticed that the switch on there was red and it said (pending - No IP), so then I checked the browser UI and find  that the switch is disconnected and there's no IP address. to configure you have to enter an IP address. IS there a way where I can completely wipe everything and setup it up again as new because I also don't have log in information for the switch as the older owners did not leave it behind?
