My power went out last night and when it came back on my wireless was out. I had settings saved (2wire) but when power came back on, the Wi-Fi network is no longer there. After resetting the gateway a couple times, I can see that the Wi-Fi network now starts with arris and not 2wire or even the network name on the actual box - starts with att5a...all the lights on the box are green but I cannot get on the internet even by plugging in an Ethernet directly into the computer from the box. Any advice? Tech isn't supposed to come out for another 3 days ugh.
