Here is the problem. I have a Roku hardwired to the primary router and a computer hardwired to the secondary router. Both devices can access the internet, but the Roku can not find the computer and the computer can not ping the roku. It gets a Destination host unreachable.
I am missing something in the set up of my LAN. Any advice? BTW... this set up worked fine with the TPLink on stock firmware and only broke when I went to DD-WRT.
I did find a workaround, but not exactly a fix. When I connect the Roku to the TPLink wirelessly, it works fine and all computers on the network can see each other.
I wonder if it could be an issue with the physical cable? As I mentioned, the wired setup worked before the the DD-WRT upgrade.

There are a lot of bad cables. Especially those that is shipped with the equipment. For a Gigabit connection all 8 wires in the cable must be connected. Cheap cables have only four which is good for a 100base-t interface.
