Lost Network Connection

Live Hub is connected to router via ethernet cable. and to the TV with HDMI.  Not sure if this issue is impacting this problem but I recently had to reconfigure the network because of a power outage.  Now the live hub will play the media on the TV but I can not access the live hub from  my computer.  Any suggestions on how to get this resolved?

Ok, exactly what did you change when you reconfigured your network?
