As i got to work this afternoon, several of our wi-fi computers were unable to connect to the network. I simply restarted them, and reconfigured the WPA-PSK and everything worked fine. When i asked a co-worker what had happened, she said she didnt know exactly, just that "that box thing was making a noise, like a screaming yak" as she pointed to the UPS.
Now, a screaming yak? I dont think i have ever heard a yak scream, or much less heard a noise come from a UPS that i would figure to be a screaming yak noise. Anyone have any idea what would cause this? We did loose the phones while the scream went on, but the building lights were all on, so i dont think we lost power at all.
WTF is going on with this UPS?
