Motorola SB5101U modem completely bricked

by salilsurendran / September 8, 2012 3:14 PM PDT

I recently moved to my new home and I asked Comcast to disconnect my service at my old place and transfer it to my new place. I connected my Motorola SB5101U modem and wireless router at my new home and it worked well for a week. I had to disconnect my modem and then reconnect it. After that my modem is completely bricked. All lights are solid green(none are blinking). If connected to wireless my computer will connect to the wireless but will not be able to access the internet. Wireless icon in task bar will display a yellow exclamation icon. I tried everything disconnecting the wireless router, plugging the network cable directly to a laptop, spent an hour and half with tech support. However there is no way to access the internet. I tried directly accessing the modem by entering the ip, after directly connecting my laptop to my modem via the ethernet cable and even that is unsuccessful. When I enter ipconfig on a command prompt on my system it shows no default gateway in the sense that it doesn't recognize my modem at all? What I believe happened is that when I reconnected my modem after first disconnecting comcast flashed my modem with firmware which then caused issues with the modem. Comcast is sending tech support of Tuesday who will most probably give me a new modem but I don't believe that this is needed. Is there a way to reset the modem to factory defaults. There is no reset button on the modem and the web page of the modem is not accessible.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
