    Extremely low network speed problem


    I'm using Windows 10 Pro. My Internet speed is very low. I've had a very reliable and knowledgeable COX cable senior technician to my home for almost two full days. The signal coming into my home is a little over 100 Mbps. However, only three feet from the router, it drops down to 20 Mbps or lower. The technician tried everything including five brand new routers - all with the same result. The modem was also changed five times - all brand new and of different brands. The signal coming into my modem is constant at a little over 100 Mbps. There is nothing more he can do. There are no obstacles between the router and my computer. I also have tried several other computers with the same poor results. So I present this serious problem to this forum for help.

    :)

    Network speeds drastically reduced overnight.


    Issue:Overnight my download speeds have dropped drastically on this PC. Other devices show typical speeds of 65 Mbps down and 10 Mbps up. This PC is showing roughly 5-7 Mbps down and 10 Mbps up on 5 GHz network and around 25 down and 10 up on my 2.4 GHz network. This is consistent over multiple tests and browsers of course.

    Info:

    • Windows 10-1511 Build 10586.164
    • No firewall/AV enabled (Windows Defender disabled in GPEdit.)
    • Linksys WMP600N Wireless adapter (802.11 b/g/n Dual band).
    • D-Link DIR-850L router (802.11b/g/n/ac Dual band).

    What I've tried/checked so far:
    • Malwarebytes turns up nothing on full system scan.
    • Task Manager / Resource Monitor shows nothing is using network out of the ordinary.
    • Tried 4 different WLAN driver versions with the same results no matter which is installed.
    • Ran TCP/IP stack reset (netsh i i r r).
    • Reset winsocks (netsh winsock reset).
    • Flushed DNS.
    • Restarted PC.
    • Powercycled router/modem.

    Attempting Ethernet would be extremely challenging and I'm 99% certain this is specific to the WLAN adapter. Any suggestions or ideas would be greatly appreciated.
