Router Not recognizing full ISP speeds

The ISP has fiber to the house. I have CAT8 from their box directly to the router (50').

 

when I went from 25mbps to 100mbps. The router did not reconize that change and I had to do a complete factory reset. The router holds a very stable 96 down and 98 up speed at that level. 

Now, I have upgraded to 250mbps up and down, but the router again will not reconize this change. I have reset the factory settings, but the router still will not utilize theISP speed on either LAN or Wireless.

 

Should I just scrap the Netgear and go get another router, or is there a reasonable fix to this issue?

 

thanks'

    Which router model?

    Which firmware version? (not "the latest")

    Do you have QoS on or off?

      Thank you for the great responses. They were very helpful.

       

      my model is R8000, the QoS is off. I connected a laptop to the wire feed at the router and got 98 in both directions. I then connect the laptop directly into the ISP fiber box and I got 230 mbps down and 200 mbps up. So, it is evidently the the cable, not the router. 

      I will remake the connectors for the cable and retry. If that does not correct the issue. I will run a new cable.

       

      Thanks' again for the input!

  • Unless you have QoS configured (which voluntarily limits your speed in favour of better latencies), the router is pretty much out of the loop with your WAN speed (aside from obviously a technical limit of the maximum routing throughput it can cope with). This is usually something your ISP's infrastructure and your modem/ ONT establish as part of the handshake, the router then just throws at it whatever it can (via its internal 1 GBit/s (or faster with highend gear) link ethernet between modem and router).

     

    If you do have QoS configured, you need to do a new speedtest in its configuration page to update the settings to the new line limits.
