CM500 capped at 100Mbps

I replaced the xfinity cable modem with the CM500-1AZNAS modem. The download speed is stuck at 92Mbps.  my earlier xfinitiy cable modem was getting me 200+Mbps.

Called Xfinity and they could not solve this issue on their side.  I've seen one more thread on this forum on this same topic but no solution . 

 

Any idea how to resolve this issue.

 

Standard validations done so far below:

1. test performed with laptop connected via ethernet to the cable modem. ( no router)

2. Powercycled the cable modem

3. xfinity tried resetting the connection from their end. 

 

Thanks in advance.

    have you tried replacing the ethernet cable? make sure its cat5e or greater. 

    What computer is it? It sounds like you're connected at a fast 10/100mbps connection and not gigabit. 

    any other computers you can try testing with? 

    are you directly connected to the modem or is there a router connected? if so, what router is connected?
