I did nothing but add a 15, 20 and 35.00 dollar cable to my router, 15, 25 and 100ft long. The DL increased by 10 X and the upload by 3 X. I used flat Cat6. Best 100.00 investment in a long long time.. I didn't have errors before, I didn't after. But the quality of everything amazed me. The terminal connection quality, the heft of the ribbon cable and the DL/UL speed increase.. A C-note.. Happy Happy.
