    Let my laptop has a stable connection with my home wifi without any external device assisted.

    Device: Acer Aspire V5 573PG
    Wifi chip: Qualcomm Atheros AR5BWB222 Wireless Network Adapter
    Ethernet chip: Realtek PCIe GBE Family Controller

    All mobile devices (IPod touch 4 gen, IPad mini 2, a few one year old android phones and tablets) can connect to Wifi.
    The laptop is able to connect public wifi and tethering (coffee shop free wifi, government free wifi, daily timed free wifi by network company, Android portable hotspot. Android USB tethering etc.), but not my home Wifi.

    Laptop succeeds to connect to Wifi, the internet speed is either limited internet or no internet.
    Laptop always fails to connect to Wifi
    Laptop fails to use cable to access internet through my home wifi router (Ethernet).
    Run "Troubleshoots Problem", it says problem with Wireless Adapter or Access Point.

    -Succeeded Attempt:
    Use Portable Wifi USB Adapter
    Use my phone to connect to my home wifi and do Android USB tethering to share internet with my laptop.

    -Failed Attempt::
    restart wifi
    change cable(Ethernet)
    netsh wlan show wlanreport
    Roll back the network adapter driver
    update the network adapter driver
    downgrade the network adapter driver
    Type netsh winsock reset and press Enter
    Type netsh int ip reset and press Enter
    Type ipconfig /release and press Enter
    Type ipconfig /renew and press Enter
    Type ipconfig /flushdns and press Enter
    Temporarily turn off firewalls
    Temporarily turn off any antivirus or malware-prevention software
    Uninstal/disable the network adapter driver and restart
    Uninstal/disable Wifi mini port
    unchecked Internet TCP/IPv4 from WLAN Properties
    unchecked Internet TCP/IPv6 from WLAN Properties
    Set up default gateways with my ip address
    Not using Bit Defender Internet Security
    Not using Mac Free
    Change Wifi brand to 2.4Ghz
    Change Roaming Policy to "Very High" or "Normal"
    sfc /scannow, result: cbs.log error, that's all

    Please help my laptop connect to my home wifi again
