Can't connect the ethernet port on an MR60 to a switch, it doesn't seem to recognize the switch.

I hope my troubleshooting procedure may help others. My configuration is below

Xfi Modem(comcast) >>> MR60 Router >>> TP-Link TL-SG108 Unmanaged 8-port switch

Problem: Unable access internet from the TP-Link switch.

Solution:

1. Establish direct LAN connection from your MR60 to PC and ping MR60's ip address. 

      a. Success: Your router and the cable is good.

      b: Failed: Try using different network cable.

2. Establish LAN connection to your pc from the switch and see if you can ping MR60's IP address.

      a. Success: Your switch is probably working fine. Check other ports on the switch.

      b. Failed: Follow these steps in order

                         i. Disconnect all the network cables on the switch including power.

                         ii. Reboot Modem first then Router(Wait until both established successful                                 connection)

                         iii. Connect Power cable to the switch.(Wait for 1 min)

                         iv. Connect LAN cable from your MR60 router (Wait for 2 min)

                         v. Now connect the network cable from switch(port 2) to your PC and ping

                             MR60's ip address. This should resolve the issue. Then connect rest of                               the network cables to the switch.

I hope this helps!
