Multi gig access RAX70

Not sure if this has been touched on, but I have Xfinity, with 1.2Gb plan.  I'm avging 400-650mb download, RAX70 router with V1.0.13.128 firmware, CM2000 modem, TP-Link TL-SG105-M2 5port multi gig switch, ASUS 10Gb network adapter, CAT8 cable.

 

I'm trying to get the multi gig port to work on the router, but everytime I try to use it, I lose internet access.  WiFi seems to work, but access via PC LAN is a no go.  I'm forced to factory reset the router.  Am I missing something in order to get the full potential of my router and setup?

The basic answer to your question is yes, you are missing something.  The multi gig output of your CM2000 is a single 2.5 Gb Ethernet connection.  The multi gig input of your RAX70 requires two 1 Gb ports aggregated together (LAG) using two Ethernet cables.  A screen snip from your RAX70 manual (available from the downloads section above) is attached.  The multi gig marketing description of your modem output does not match the multi gig (with port aggregation) marketing description of your router input.   The devil is in the real life details.  There are no adapters that I am aware of.

 

Be sure and heed the warning noted by @Retired_Member above relative to switches and aggregated ports.

Re: Multi gig access RAX70

It won't work with your current setup. reasons why

1. The RAX70 uses port aggregation to hit multigig speeds. 

2. the CM2000 doesn't have port aggregation. It only has one 2.5 gig port

3. the switch you have is a simple switch so it can't go cm2000--->switch---->router.   Some fancier managed switches have dhcp built in with port aggregation. Yours doesn't. So you have to go modem---->router---->switch/devices

 

But even with that said, you should still be able to hit 940mbps (ish) using that router/modem combination. The 450-600 that you're getting, is that wired or wireless? Have you tested your wired speeds directly from the modem?

It's a wired setup.

And what about question number 2?  Have you tested your wired speeds directly from the modem? 

 

What device are you using to test your throughput capacity?

 

What application are you using to test your throughput capacity?   Recommend the Ookla native operating system application available from the play store.
