Hi all,

 

Firmware version:0.6.0 1.13 v0021.0 Build 160125 Rel.52064n

Hardware version:TD-W9980 v1 00000001

 

My problem is that 2 of 4 LAN ports of My TD-W9980 are not working. 

I switch the same cable into Port 2 -> Link starts to wave and everything works fine.

When I connect the same PC to Port 3 or 4 nothing happens: No link light starts to wave and

PC's connection status is "Cable disconnected"

 

Tried to Reset the modem and updated the Firmware... didn't help.

 

Anyone faced this issue too ?

 

P.S. It never worked from the moment of purchase, and since I was busy and didn't really needed additional ports, I 

didn't send the modem to lab.

 

Thank you.
