I bought my Live Plus in Feb. of this year, along with a BUFFALO WLI-UC-GN for the wireless.
As of a couple days ago, the unit will no longer see the wireless adapter. When I go into network settings, I get no choice for wired or wireless.
Nothing has changed on the unit (no firmware updates, etc.), though I did notice that at some point the LED on the adapter stopped flashing on access and stays lit as soon as the power is turned on. I believe this coincided with the last firmware update, but I am not sure. Reguardless, it did not alter the functioning of the device. I continues to work fine until now.
