Hi, everyone, this is my first post here. It would be great if you can solve this for me. I'm fixing an ancient Toshiba Equium P200-178 for someone who's lost his job because of the virus.
The laptop was shipped with 32 bit Vista. It was dog slow and the user reported BSODs so I just formatted the disk and installed W10. Device Manager said the Atheros wifi adapter 'cannot start. Code 10'. There were about 10 other yellow flags in Device Manager. Some of them said 'This device cannot find enough resources that it can use. Code 12.' The laptop has a wifi switch on the front - this was switched on.
I updated Windows with a dongle. The dongle kept disconnecting from my wifi for no apparent reason, but I eventually finished the updating. The laptop has only 1 GB RAM, so everything is terribly slow. I looked for the manufacturer's drivers, which are on a site provided by Dynabook. There are no W10 drivers there, but I was able to check that the BIOS is up to date.
I found this thread https://www.windows10forums.com/threads/atheros-wlan-chip-shuts-down.12910/. The user has the same driver version, so I installed the two other versions recommended in the thread. Nothing changed.
At some point I removed the wifi dongle and the Atheros started working normally. I have no idea why. After 5 minutes it reverted to the state it was in before, i.e. cannot start. Code 10. Also, the USB sockets became very erratic at autosensing things plugged into them. Sometimes I could not get them to function without a restart.
In the Network Adapters section of Device Manager there were about 10 devices, mostly WAN miniport something or other, plus a Realtek PCIe FE Family Controller. I disabled all the network adapters except the Atheros, in the hope that this would free up some resources. The Atheros started working and it's been fine for the last hour, doing yet more Windows updating. I'm reluctant to hand the laptop back to the user because I don't trust this apparent fix and really have no idea what's going on. Many devices in Device Manager have 2, 3 or 4 identical entries. About 15 of these entries have yellow flags,
