We had a pretty serious power hit a couple of nights ago, and in the morning the Insignia Blu-Ray player and Netflix appliance was completely dead. Instead of the power button showing red when off it showed nothing at all. I tried different outlets; no dice.
So I decided to take it back to Best Buy in hopes that they might know of some cheap fuse replacement, and if worse came to worst, I would buy a replacement. But once there, they plugged it in and it had power. Apparently it just needed some time off to recover from its traumatic experience.
But it apparently suffered amnesia from the experience: it no longer new about its wireless interface. Then I remembered, that originally there was a firmware upgrade required to get that. So I ran some Ethernet to the house to plug this thing in, and tried to run the upgrade from the menu. Unlike the last time, it claimed that there was no upgrade available. My guess is that whatever address the box was looking to get the upgrade from no longer had it.
The next step was to look on the Insignia webpage, find the upgrade for the firmware, and load it onto a flash drive. Now I was able to put it in the USB slot on the back of the Insignia box, power it off, and power it spaceback on. Now the wireless interface was working again. I certainly could not find anything online explaining that I needed to do the firmware upgrade to get the wireless interface operational.
