Hello,

I purchased a single Deco X55 pro mesh unit for better internet coverage in my home. My new internet provider is Verizon and they sent an ASK-NCQ1338 5G home gateway/router.  I am getting between 270 & 350 Mbps consistently near the gateway but in other areas of our home it drops off to between 90 & 120 Mbps. We have a 3 level (with basement) ordinary constructed center-core floor plan home that is roughly 40'x30'. Since the 5G gateway. The best reception for the gateway necessitates its location at a 1st floor window about 15' from an adjoining exterior wall. I have 2 cat6A cables that were pre installed through the walls/floor to a central 1st floor location which is where the Deco unit now resides. I do not need blanket coverage for every corner of the house but the central placement should theoretically give me better strength to the areas where I will need it. 

I could not find a "one-stop-shopping" video or guide specifically for the marriage of an X55 Pro with an ASK1338 but did find several forums, blogs, and a couple videos that had partial helpful information. 

Initially I placed the Verizon ASK gateway in pass-through mode connecting the cat6A to the LAN-2 port on the ASK and the top 2.5G port on the Deco. The Verizon 5G WiFi network was gone and the new Deco network appeared but the max at the Deco unit was 80Mbps. I traded cables with the same result.  I also did a short run test with the Ethernet cable provided and got roughly the same result. I could not find a means to turn off the DHCP for the Deco as was suggested in fourms about other mesh units.

I reset the gateway to get it out of pass-through mode, left the short cable connected to the same ports, and restarted the Deco as was recommended in a fourm or two. Now I had both Verizon and Deco networks with 111Mbps at the Deco and 220Mbps at the Verizon gateway.

Obviously I want a single strong-signal network so I am asking the experts on here what I am doing wrong or what steps I have missed.

Thank you!
