    Ethernet adapter big problem

    Hi guys, I have big problem for internet connection. I have cable internet (Tv and internet share same cable) but when I turn on my PC icon for connection is with yellow sign (identifying network) or with red sign (cable is unplugged). They periodically blinking (first yellow than red sign) and I don`t have connection. After 20 minutes after turn PC on, my connection is back and is stable as long as I do on my PC. When PC go to sleep mode same thing happening. I have build 11082. I check cable and it`s OK. Also I try to flush DNS but same things happening. What is wrong with windows 10 and ethernet adapter?

    Most times it is because of an issue of the adapter not getting the correct info from the Gateway, same as the Gateway not getting correct info from the computer network adapter.

    If it is only during sleep. The lease is most likely getting screwed up on the gateway.

    If you lease your gateway from your ISP. Try unplugging it and then plug it back in.

    You can also do what is called an "Edge Router" setup. It is taking another router/Gateway and set if for a different IP scheme.

    Say your current gateway is accessed at You would set your router up for Then have all of your gear connected through your personal router.

    Some of the ISP Gateways are pure junk and never work great to begin with.
