I Just got an Arris 2 gig Cable Modem, I also just added a 2.5 gig unmanaged switch to which I have the modem connected to, one port goes to my pc which pc sees and good download and upload there, have another going to the 2.5 ethernet on the router and it stays red, when it was a 1 gig connection no problems, Im at wits end dont know what gives was hoping to have faster wifi, now i have none at all, if anyone has a solution, plese reply, thanks John
