Lost WiFi: 2009-12-13
03:00 AM: On my way to bed, I turned on my Sangean Internet radio to listen to KYW News Radio in Philadelphia. However, getting the list of stations to choose from returned an obscure internal error. To recover from that, I had to unplug the radio from power, wait a minute, and plug it back in. Even then, I could not connect. Then, I used the “Scan for Networks” feature to see if the radio was “seeing” my wireless network. It was not, and said, “No networks found.”
So then, I pulled out a wireless laptop, and encountered the same problem. Now, I suspected the access point — it’s a Bountiful WiFi router.
Inspection of the router revealed that the lights on it looked dimmer than normal. So on a hunch, I replaced the power supply adapter; I have three spares around. That brightened up the lights again to normal levels, and restored wireless access.
Since I keep my computers and equipment up and running all the time, I guess things do wear out after a while. 
At least this time however, the router itself was okay.
