torchwood It's an old thread but there is a lot of useful info and I will try some of the fixes in due course.
Thankyou.

Download Asus K53E laptop drivers for Windows 7 x64 | DriverPack
make sure to click the arrow on the right and then download the zip at bottom left

Attachment 422818

It looks like DriverPack wants to download an exe that searches and downloads the missing drivers. I don't want it to do that with the desktop I'm using for my internet access. And if there was a way to get that software onto the laptop it wouldn't work anyway because it has no internet access at the moment because of the problem.
I did manage to find the ethernet controller driver direct from Asus and got it installed but even with an ethernet cable linking the laptop to my router nothing has changed. Still no internet or link. I assume the other three controllers need to have drivers as well.

I download the zip into a usb stick, transfer the stick to the laptop. Move the zip into an empty folder and unzip it. (no idea what unblocking is)
Then the unzipped file shows four or five indivindual things. None of them is accepted by the laptop as suitable drivers.

Since the laptop won't communicate even with an ethernet cable direct to the router nor does it find the router (not hidden) I think maybe this machine is either faulty or has not had wifi or network adapter installed. If that is the case I will just have to cannibalise it for parts to keep the other one running.

Thanks to all for helpful suggestions. This isn't the first time I have posed a problem that could not be solved. On the plus side, I have learned not to fear looking into places I don't understand.

First step is to look at BIOS as it can have a LAN and/ or WIFI enable / disable switch.
Second is to open Device Manager and see if LAN and/ or WIFI are listed under Network Adapters

I have searched the BIOS pages and there is no mention of an enable/disable switch. I do not find LAN or WIFI mentioned under Network Adapters, only things there are: Network Controller, PCI Simple Coms Controller, and SM BUS Controller. All three have the yello alert and say no drivers installed.

I received a message from the guy that sold the laptop to me and he says the WiFi and ethernet were working before he sold it. This leads me to believe something I did when I installed the W7 Pro over the W10 has caused the problem. I am now searching for a clearly explained method of how to wipe it clean and try again for a W7 installation. The laptop had W7 on it from new but was only changed to W10 before putting it up for sale.

HMMMMM

its likely that Ethernet/Wifi are under the Other devices in that case.... also with the yellow allert

Hi

going a bit further too Mega's Bios option check
The Wifi option will likely be a drop down sub menu within Integrated devices
As the device is not showing its either not enabled or 1 of the connectors has popped off

can you run/post msinfo32, or use the BSOD posting link(contains a weath of info-- including pci/ven info)

Blue Screen of Death (BSOD) Posting Instructions

can you look in the details tab for any of those with the yellow blob what is the error code, likely 10 or 42

No luck searching out Mega Bios options in the advanced search. Too many Megas. Not sure I would know what to do if I found it anyway.
msinfo turned up the same three suspects with missing drivers but the additional info in the right hand panel was huge. Lots of driver numbers mentioned for each one. I have been trying four or five driver scanners that have been suggested now that I've got the laptop accessing the internet. They all say there are issues but won't let me get any further without agreeing to pay for a year or two membership. Not going there.

Signing off now to rest the brain. Looking out the window there seems to be a world out there that is still functioning with or without drivers.

I have made great progress. I visited a site recommended on another forum and that site did a free scan for missing or outdated drivers. It listed over 60 and I selected one that mentioned wifi controller. It downloaded successfully and installed automatically. I now only show two more items on Yellow alert in the Device Manager but since everything seems to be working OK I'll leave it at that.
Thanks to all for helpful suggestions.
