Windows 10: Wireless Antenna Stopped Working as Expected Solved

    Wireless Antenna Stopped Working as Expected

    I'm using Windows 10 in a custom built rig with a TP Link wireless antenna (PCI) for wireless access to our home wireless network.

    I've already eliminated a number of things.
    The modem-router is fine - all other devices use it without problems.
    The Ethernet connection in my PC is working fine.

    I have a gut-feeling this is a software issue. So before I rush out and buy a new antenna, I wanted to try and troubleshoot it here.

    A bit of history.
    All was fine. My wife went away for a couple of weeks, so I connected up an Ethernet cable (which I am not normally allowed to run through the house :) ).

    When I disconnected the Ethernet cable upon her return, the wireless seemed to be on the Fritz.

    It still reports a strong signal.
    But, it reports "No Internet, secured" underneath the SSID after connecting to it.

    Obviously, the browsers do not load any sites.

    I am not even able to load the modem-router's firmware interface via its IP address.
    I am not able to ping the IP address of the modem-router.

    As I said, the wireless card seems to be working, as it still detects my next-door neighbor's network (in addition to my own) and reports a plausible signal strength for it.

    Can anyone suggest how I can determine whether this is hardware or software. I think I've conclusively narrowed it down to either being:
    1. the wireless antenna; or
    2. Windows 10.

    And remember, all I did was stop using it for a couple of weeks.

    Hi onefootswill.

    Agree software. Before trying anything below I would create a Restore Point. If you don't have a Image then I would also look at Macrium Reflect. Nothing below is that drastic but Windows does have a mind of its own and having a Plan B is always a good idea. A data backup is always recommended.

    Backup and Restore with Macrium Reflect

    You could try a Network Reset. This will cause all Wireless passwords to be forgotten.

    Start => Settings => Network and Internet => Scroll to bottom of right hand side => Network Reset

    Run the following four bolded commands. Use a Command Prompt(admin)
    Do not key in info in brackets, there for your information.

    ipconfig /flushdns (Clear the dns cache)
    nbtstat -RR (release and refesh NetBIOS names)
    netsh int ip reset (reset ip settings)
    netsh winsock reset (Reset Winsock Catalog)
