The xfinity xb6 gateway only has 2 ethernet ports (eth1 and eth2). My desktop computer is plugged into eth1 and my laser printer is plugged into eth2. During the past month my printer went off-line for no apparent reason. There were no lights on eth2 so it was definitely dead. I plugged the printer's ethernet cable into eth1 and it indicated a good connection. I plugged it back into eht2 and there were no lights.
I called tech support and they remotely reset the gateway. After the reboot completed, both ethernet ports were active again.
Any ideas what may be happening? Comcast wants to charge me $40 to come out and replace the xb6.
1 ). The XB6 may somehow have gone in to bridge mode (which disables port number 2). When the device is reset, it defaults to going back in to router / gateway mode.
2 ). There may be a problem with the gateway firmware load / port number 2 which the reset cleared up.
If you want to try swapping it out, you can bring it in to your nearest Comcast store and avoid the tech charge.
