My Deco is much slower on wired and wireless network vs my previous router.  When my old router is connected (and using Deco as Access Point) to wired desktop, I get ~450 Mbps (ISP speed is 400 Mbps, cable internet).  Wireless is at ~400 Mbps.  If I skip my old router and use only Deco as router, the same wired connection to my desktop (Deco to desktop wired) only gets ~70 Mbps.  About the same on other wireless devices.  I'm using the same Cat 5E cable to the old router and to "main" Deco device using cable modem as I'm comparing the speed.  Deco is marked with v1.6, I think that's hardware version.  Can someone tell me what's wrong with Deco X5000?
