My router isn't NVIDIA SHIELD ready

Review on Amazon for the SHIELD says streaming games only works with supported routers. My TP-LINK isn't on NVIDIA's list. They must have a pretty crappy router. I have a version 1 Archer C7. The GRID streaming was working on wifi, never tried it on ethernet, I use the streaming from my computer. They do have two buffalo routers on their list. Not really needed since ethernet works better.
