I've had this problem for a little over a week with my laptop. My network adapters issue out a code 45 and i've tried the following methods to try to fix it with no avail:
Repairing PC registry - with no corrupted files found
Running a DISM scan
Uninstalling one of the wireless drivers
Running the troubleshooter but it detected nothing
Scanning for hardware changes did nothing
Multiple scans in the BIOS, more about that below
I have the latest windows 10 update but since i don't have access to the internet on the laptop i cant update my drivers or anything like that. I cannot pickup any networks and plugging an Ethernet cable in doesn't give me access to the internet either, i also ran an extensive system check and my wireless systems passed the test but the wired adapters failed it. I've also tried nearly every Youtube fix but none of them work. This is an integrated NIC and prior to it not working , it was working fine until i turned off my laptop for an hour or so to come back to no internet connection and no option to login using the pin, i had to use my password to login (i'm not sure if that's important i'm just throwing it out there). The only thing i haven't tried is doing a hard reset on the laptop to delete everything and start over but i can't do that since i have important information and applications which are not backed up and have no way to back them up at the moment.
The only odd thing that has happened prior to this was my volume being very quiet even on max sound settings and my microphone not working.

I understand your concerns.
In that case, I would suggets you perform the Wireless Module Test and check.
1. Power off the PC and make sure that it is completely powered off.
2. Press the power button and the moment you press the power button immediately start tapping F2 key, you should see the system diagnostics screen.
3. Look for the component test, under that all the hardware will be listed, please choose Wireless Module Test and initiate the quick test.
Note: If it fails it will generate a 24 digits alphanumeric failure id, please capture that.
Please let us know the result.
Have a nice day!!

Hello,
I've done the test before and did it again, it passes the test but fails the wired network check (without a provided 24 digit code)
I was thinking about getting a USB wireless adapter as a temporary fix but i can't install the driver of the adapter since it requires either an internet connection or a disk drive, neither of which i have and i can't install the driver elsewhere since i only have one laptop. If these fixes don't work, are there any USB wireless adapters which do not require driver installation or are supported by windows? If so please let me know.
So far i think it's a hardware problem (since no fix has worked so far) but i have no way of checking.
