    "you can reinstall the WiFi driver over the existing one by right-clicking on the netrtwlanu.inf file & selecting Install."

    I tried this and i got this.

    Then use Device manager to update the driver while you are connected to the internet [through your LAN cable] and go straight to the 2018/2019 version.

    Which driver do i update?

    Ignore the killer. I have uninstalled that.

    But now the ethernet won't connect. So I guess I need to have the killer network installed. Lol.

    Yeh I need to install the killer network back because there's no ethernet connection now.

    So give me a while and I will get that done.

    Dis- then re-connect the WiFi device then, in Device manager, click on Scan for hardware changes** if it has not already done that automatically and rediscovered the device.

    ** In Windows 10 that is an icon on the Device manager toolbar & an entry in its Action menu. I think Windows 7 only has it in one of those locations. It might be that icon on the right.

    I got the killer network back up and running and my ethernet is connected right now.
    I tried clicking on scan for hardware changes and i got this.

    I don't know why it cannot find the correct driver for this adapter. I searched while the ethernet cable was connected.

    I'm trying this WiFi adapter on the downstairs laptop now.

    Im installing the driver from the cd because I couldn't pick up the driver through the Internet.

    It's strange. I tried entering the 8 pin code but it don't recognise it lol.

    And this I'm trying on the laptop.

    Im thinking of going to the shop to buy a new WiFi adapter for my desktop before the shop closes.

    Is that a good idea? Lol.

    Try that link for Security key which I assume is password.

    Any chance you have MAC filtering enabled on router?

    If that does not allow you to get a working WiFi USB -
    Here is the v1030.38.712.2019 I used [Win10x64 but I'd bet it is the same for your Win7x64]. Extract the zip file contents somewhere convenient then right-click on netrtwlanu.inf and select Install.
    Realtek v1030.38.712.2019.zip

    I have just re-tested this procedure on my own computer and it works correctly. I thought Win7 responded to inf files in the same way but if you have any problems try updating from Device manager instead -
    - Right-click on that duff entry [Other devices, 802.11ac NIC] & select properties,
    - Driver tab, Update driver, Browse my computer, browse to the folder you extracted it all to, OK, Next.
    [I just re-tested this procedure to make sure I had remembered it correctly]

    Once again, there is an issue that needs to be dealt with before you can address the wifi card problem. My tuppence worth is in the next post.

    Once you have resolved whatever the problem is with your ethernet router connection, check your HardwareID in Device manager -

    Select the device then, instead of the Driver tab you looked at before, choose the Details tab and then select HardwareID from the dropdown list. You can then right-click & copy the entries. Mine is USB\VID_0BDA&PID_C811 [I used the shorter of the two IDs listed]. This procedure works even though the device is currently unrecognised & uninstalled.

    Optionally, run a Google search of that ID to see if you can get confirmation of the device name Realtek 8811CU. I am not suggesting that you accept any of the results as trustworthy sources for the driver.

    Then go to the MS update catalog & search for something like Realtek Semiconductor Corp. - Net windows 7

    Click on the top of the date column and page through the results until you see Windows 7 entries. For each one, click on its name [the left-hand column] then the Package details tab. Check for one with a matching HardwareID then download & install it. If you have a choice then choose the 64 bit one [x64], otherwise the 32 bit one [x86]. Not the AMD64 one unless you have that type of processor.

    About the router problem -

    Perhaps just turning the router off then on again might be enough but that is really grasping at straws.

    The fact that the PIN from the router's label does not work indicates that, at some stage, you deliberately changed the router's PIN [and presumably the full Security code] as a security measure. I have only ever used two routers but they both reset these to default if the router was 'reset'. I appreciate that doing this would involve further effort such as digging out a note of a Security key that the router might then need to connect to your ISP.
