Hey there - curious if anyone had LAN issues when setting up their Archer C2300.  Specifically, if using more than one LAN port caused the router to lose internet connectivity altogether.  When I first set it up, the wi-fi upgrade was immediately apparent.  So, I went ahead and plugged in the two ethernet cables I had been using on my old router and then I immediately saw the internet icon turn red on the C2300 and all connectivity was gone.  When I just use one of the two cables there are no issues, but once the second one is in there it all craps out.

The two ethernet cables are used for 1) my hard-wired home network (ehternet jacks in the house), and 2) my DirecTV connection.

Anyone happen to know if this router simply doesn't support concurrent port usage (if so, why bother putting four back there)?

Haven't heard jack from "support" so any insights at all from the group here are greatly appreciated before I just cut bait and return it.

Thanks!
