"Can't connect to this network" = help please!

For the last few weeks I have been unable to connect to Wifi on my PC (my phone, tablet etc. are all connecting fine)

My PC is detecting my Wifi but when I attempt to connect, I enter the password and it says "cant connect to this network"

I have been using my mobile phone USB tethering to access the internet when on my PC but it is getting a little annoying having to do this each time I want to use the PC

Any ideas?

    Right click and use the troubleshooter. My laptop shipped with Win 7 and since I upgraded to Win 10, it has connection issues after updates. Troubleshooter reassociates everything and it works fine afterwards. I do not know the permanent fix to this, if you find it please share. I literally just ran a troubleshoot to get on the net this morning.

      Have tried previously but no luck, it just prompts me to connect to the network and then the same thing happens

      •  

        Maybe your network card fried. Run a malwarbytes check just in case its malware.

        •  

          If that were the case wouldn’t the network be undetected?

          •  

            @Heracles26: Maybe, you don't have airplane mode on do you? You can also try forgetting the network and letting the pc find it again. Updating the driver as mentioned below is a great idea too.

            •  

              @DisabledUser152521: Tried all that! Will update the driver when I get home!

              •  

                @Heracles26: I hope it all resolves itself, I am fresh out of ideas. The last thing I can think of is to check in device manager that it reports as working, and if you have Win 10 check under Device Performance and Health to see if it is reporting any issues.

      Has this ever worked even once in all of recorded history?

        Surprisingly yes. I've had it work for an incorrect IP configuration before and for printers. Only under Win10 though.

    Have you tried uninstalling the wireless network driver and reinstalling from the manufacturer's website?

    It's possible there is a dodgy driver or some settings have changed.

    •  

      Will try thanks

      •  

        Grab the latest manufacturer driver for your WiFi / Bluetooth card from Station-Drivers:

        https://station-drivers.com/index.php?option=com_remository&...

        Companies like Dell, HP, etx. can be a few revisions behind the latest manufacturer software.

          Or even better go to the manufacturer's website.

          •  

            @Clear: Chipset manufacturer sites don't always list the drivers in a way easily accessible to the public.

              @xuqi: But they're always up to date, correct and less likely to be tampered with.

    Does your PC connect to ANY wifi?

    •  

      My own Wi-Fi is the only network that is visible so I don't know

        So you don’t have friends or family with wifi? Or even a maccas near you ?

        Hotspot via wifi from your phone and test your wireless card, if that doesn’t work then uninstall and reinstall drivers as suggested.

        If that doesn’t fix it, buy a $50 USB adapter from officeworks should.

      •  

        Try hotspotting your phone and tethering your computer to it to see if it works.

    have you tried turning it off and then on again?

    •  

      Dammit I only opened this thread to say that!

    •  

      Genius! haha yea I have

    Can connect to by wifi to your phone? This will test your computers wireless card.

    •  

      Haven't tried that actually, will attempt when I am home

  •  

    When my laptop has problems connecting I do the following:

    Turn off the WiFi source
    Turn off WiFi on laptop
    Turn on WiFi source
    5 seconds after that turn on WiFi on laptop
    5 seconds later it appears in the list of connections and then connection is usually successful

    I don't know if these actions are just a placebo or not but it usually works again after doing this.

  •  

    Here is what I would do in order of complexity/effort:

    First I would try power cycling both the PC and wireless router. ie. turn them both off and on again.

    If that doesn't work then I would try the "Update Driver" option.

    If that doesn't work then I would "Uninstall Device" and reinstall drivers.

    If that doesn't work then I would find the manufacturer of the wifi card and install the drivers from the manufacturer's website.

    If that doesn't work, I would try getting a USB wireless card.

    If you don't like having an external USB card then, I would open up the laptop and reseat the wifi card in the slot.

    See how you go with these steps.

    Last time it happen to an iPad at home,all devices can connect except this particular devuce. Two days no wifi but can connect fine with sim card. Turn out a person in the house play around this dodgy android app that can disable wifi in any device.

    I would suggest at the mean time you connect your PC with lan cable.

    Go to your router settings and change the wifi channel manually to a lower one.

    Just happened to me yesterday after buying a new NIC had a ipconflic
    Router log DNSMSAG error or something DNS DHCP error
    Turns out I had the pc set to static the new nic was trying to logon with machine ID and new IP causing the conflict.
    Removed the static IP from the DHCP and worked again.

    •  

      How do I do that? haha

      •  

        look in routers log settings will tell you why it can't connect and post here.

    Sometimes the 'saved' settings are corrupted. So basically, it sees your network and then tries to connect with existing settings (which are wrong), and then can't connect.

    • Remove the saved SSID settings, then connect as a new connection and enter your SSID password in. Let me know what version of Windows you're running, and I can help further.
    • Test with your phone as a WAP.
    • Remove and install latest drivers.
    • Buy USB wireless (~$30).

    Had same issue with my brothers hp laptop is there any other buttons on your modem near the wifi button like a direct link and also a setting on your laptop for direct without using a password not sure what it's called maybe look it up. ?

    Temporarily set Wi-Fi security to none on the wireless router and try connecting again. If that does not connect then change to a new SSID and no security and try connecting to that.

    If your PC connects with no security, then the problem is likely to be a corrupt setting in Windows. If your PC does not connect then the problem is likely to be a bad driver or failed hardware.

    Sorry for the delayed reply all.

    I uninstalled and reinstalled the wifi card drivers and had no luck.

    I turned on my mobile hotspot and attempted to connect to the network and the same problem occurred; it's being detected but "cant connect to this network" appears

    So despite my wifi card being able to detect networks, im guessing its somehow faulty? not sure what to do next

    •  

      Sounds faulty now or Windows issue

      3 choices.

      1) Bring to a shop to properly diagnose & fix (will cost you)
      2) buy a usb Wifi dongle to see if this works (this costs $9)
      3) use a LAN cable

      Personally I'd buy the usb Wifi dongle to test, do a Windows repair job through Windows start up cd then buy a new NIC.

      Keep us posted

  •  

    I’d go into the driver properties and test out every frequency to see which one detects the router

    Some routers limit the numbers of devices that can be connected at the same time or there is some data limitation.
    As every suggest go and restart your router, test the wifi with your phone, that the Router is the issue use some key combo to reset it.

  •  

    press the wps button on your router

  •  

    What type of laptop is it?
    What model router
    For the sake of the exercise, log into your router and turn of the password for your wifi.
    see if you can connect then

  •  

    It's a Windows issue. Just reinstall windows and it should work.

  •  

    If you are using 2.4Ghz Wifi, try to disable Channel 13 in your router. Some older laptops could not connect to higher channel of 2.4Ghz.

  •  

    Windows 10 yeah? Try this one.

    Select the Start button, then select Settings > Network & Internet > Status > Network reset.

    On the Network reset screen, select Reset now > Yes to confirm.

  •  

    Go into Device Manager,
    Network Adapters,
    Find Network Wifi adapter,
    Uninstall,
    See if it refresh it self or download the current one just in case.

  •  

    Thanks for all the replies and help all.

    I will be purchasing a wifi USB dongle and seeing how I go with that

  •  

    UPDATE:

    I ended up buying a WIFI USB dongle, plugging it in, disabling my internal WIFI card, and perfect - connected to the WIFI immediately

    BUT

    The WIFI disconnects literally every 2 minutes (my room is not far from my modem and all other devices have perfect connection from the room) so no idea what to do now. Any tips??
