CM1000 not connecting at gigabit speeds

I'm having problems with my gigabit connection, I'm just able to get  350 Mbps instead of 900+ I already reset the modem, did factory reset. Nothing works.

RCN in NYC.
Yep according to them I should be getting gigabit speeds. But the max I get is 500mbps.
Connecting direct the modem to my desktop computer using an ASUS XG-C100C 10G Network Adapter PCI-E x4 Card.

What FW are you on? 

 

this looks could probably be configfile/bootfile or a capacity issue. Have you tried any other RCN supplied modem and recieved close to 800-900 Mbps ?

      since you have tried 2 different retail modems from 2 different companies, I would err on it being RCN issue (boot file or capacity/signal issues)

      do not see anything wrong in status message. 

       

      Only thing remains is the bootfile/config file.
