So my router has 4 ports. Gb Eth then port ethernet port 1-3. The only port that works is Gb Eth the other 3 wont connect to internet. So instead I had to hook up a second router and use a cable to plug Gb Eth to the other router so that I could plug in my other computers to that router but now all the computers get 300 ping. What do I do?
