My Acer Aspire F15 recently facing a WiFi connection problem.
I connected to my home WiFi, everything show in computer seem normal. Showed connected to internet, but when open browser (chrome, Firefox, Edge), all cannot access to Internet. Even Microsoft update also cannot.
Ethernet works normally. I brought my laptop to service center, they checked on my network adapter work normally, but still cannot access to Internet. They advice me do a full format, it probably software problem.
I had formated twice, the problem still there. Is it the problem come from between the windows 10 and the network adapter driver?

  • Hi,

    Go to Settings, Network and Internet, click WiFi in the left pane, click Manage Known networks in the right pane, click any unknown networks(neighbours') and slect Forget. Reboot and see whether it helps.

  • Hi,

    Download the driver version 12.0.0.191 from acer support site, extract it, go to Device manager and unistall the current driver, without rebooting install the downloaded driver and see whether it fixes the problem.

    No. It won't work.
  • Hi,

    Try removing the current WiFi connection from Network connections and create a new WiFi connection, go to Control panel, Network and internet, right click and disable WiFi, then delete it, remove the driver from Device Manager and create a fresh WiFi connection.

    Hi

     

    Your explanation is a little off, so it is difficult to ascertain the problem.

     

    IF you "connected to my home WiFi" and could not access the internet it suggests a firewall or gateway problem.  Discount firewall as ethernet leaves the machine.

     

    So the next step is to accept the WiFi card works, as it shows in Device manager and the Service Centre checked it over, and establish by how much does it work, if 0% then we goto square 1 and do all the things everyone else has done.

     

    CLI, Command Line Interface, DOS box or Command Prompt as administrator.  Type these...

    getmac just to list the 3 devices, Ethernet, BlueTooth and WiFi (with no ethernet cable in use)

     

    getmac just to list the 3 devices, Ethernet, BlueTooth and WiFi (with no ethernet cable in use)


    ping 127.0.0.1 NO ethernet cable connected, and the result should be similar to this....

    Ping statistics for 127.0.0.1:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
    Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms


    The ones above how there is a card in place and it does the basic test. If so...


    ipconfig -all and look at the part below and copy and paste in please.

    and from this point it should be possible to get an outside connection.
    The next part is very personal and you should note down the important parts
    BUT DONT PASTE them here.

    DO NOT GIVE YOUR KEY AWAY, JUST WRITE IT DOWN. DO NOT POST IT IN ANY FORUM.

    C:\WINDOWS\system32>netsh wlan show profiles

    Profiles on interface WiFi:

    Group policy profiles (read only)

    User profiles
    -------------
    All User Profile : WiFi2the World
    All User Profile : ThePubnextDoor
    All User Profile : StreetSmart
    All User Profile : MyOwnHouse


    Next you note the name of your home WiFi


    netsh wlan show profile name=MyOwnHouse key=clear


    Connectivity settings
    ---------------------
    Number of SSIDs : 1
    SSID name : "MyOwnHouse"

    Now we now my WiFi works and how to connect it.
    If you can get written down or printed out the above info then a solution is in sight.
    The RED print should be kept secret.

    Hi

     

    I can only see that the default gateway is 192.168.1.254 as is the DNS and DHCP servers.

     

    I would expect that the DNS would be an external number.

     

    ping to 8.8.8.8 and even temporarily set your DNS to 8.8.8.8 to try and get an external connection.

    I sent in service center for warranty. The technician said the WiFi intermittent and ping very high. They need to check on it.
    I will update here what is exactly the problem when take back from them.

    I already took back the laptop from service centre. It was network card problem. They replaced a new network card for me.
