    Hi huynhducloi,

     

    Welcome to NETGEAR Community!

     

    Thank you for reaching out. May we know what is the model of your Cable modem? Did you test another ethernet cable?  

     

    Please do not hesitate to let me know if you need further assistance. 

     

    Regards,

    If your handwired wire has a not completed pair it could be connecting at 10/100mbps connection and not gigabit. 

    This is what I see most often. 

    Try a good quality cat 6 cable and check the connection. If thats fine, then you'll need to check your cable ends. (usually where its bad).

    I've also seen people strip the protective cover off prior to crimping and nick the cable causing bad connections. It can be a little frustrating when you first start handwiring cables.

      hi, thanks a lot for following -up.

      The interesting thing is that i have tested my hand-made ethernet cable with RJ45 tester (etc. cable tester), and all the lights from 1 to 8 is light up correctly.

      I don't know if netgear needs special wiring instruction. I tried the netgear provided ethernet cable and it lights up green as expected, but i just dont know why my hand-made not working.

        Did you test different ethernet cable? CAT6 is recommended.
