On November 2, 2021 all of my wifi went out. I ran down to my data center and was confused. I first looked to see that my Verizon Fios router was online and it was. I had TV working. I then looked at my Ubiquiti Networks UniFI Security Gateway and I noticed on the left where it says Console, that green light was blinking and no other lights were on. I changed cat 6 cables and tested everything. The last thing I did before buying a new USG Security Gateway was to change the power supply. I noticed it was working somewhat but not entirely. I went throughout my house to find something that would work, plugged it in and watch the video! I replaced the USG power supply with a 12v 2a power supply . I went ahead and purchased this to replace the broken one
