Older 1TB Time Capsule set to 50% radio power, then I upgraded firmware
I have a 1TB Time Capsule version (A1355), not the latest TC with 802.11ac, that I've run for about two years. I reduced the output power to 50% intially with OSX 10.6 and I assume Airport utility v5.6. I upgraded to 10.7 and 10.8, and the subsequent Airport Utilities, v7 or whatever. Noticed the ability to select output power disappeared awhile ago, but never really cared.
Recently, I have been having connection issues, and have noticed a lot of neighboring wi-fi signals blasting at huge RSSI values. There are five or six networks around me with RSSI -90, while my 2.4GHz and 5GHz networks hover between -50 and -70.
Is it possible my TC is stuck at 50% power still? That the firmware updates didn't default it back to 100%? If I do a factory reset, I assume that will restore it?
