Acer laptop Win 10 Won't Turn On Wifi (used to work)

Question

I'm working on a laptop for a client. It's an old Acer 5253-bz692. WiFi was working until the client came to pick it up (of course). I updated to WIn 10 1703 and WiFi continued to work. The only thing I did that could be related is I upgraded the RAM, which is nearby the WiFi card.

Here's what I've done so far:

1. Settings > WiFi Settings > Turn On WiFi (it shows as off). That switches the toggle, but never turns on. If I reload the WiFi settings, it shows as off again.
2. It does have a keyboard shortcut to enable/disable WiFi (Fn + F3), but that does nothing at all. (the other F-key hotkeys work). This machine does not have a hardware switch for WiFi.
3. Reinstalled WiFi driver.
4. Replaced WiFi card, installed drivers.
5. Disabled power management (don't allow Windows to turn off wireless)
6. Found a couple posts that said with Intel cards to disable 40hz. Now explicit setting for that here, but found one similar and changing it did nothing.
7. I don't see anything in the BIOS for enabling/disabling it.
8. Restarted machine multiple times. Also pulled battery and cord and held power for 30 seconds.

Any suggestions?

Solution

It's now working after multiple restarts and continues to work after more. The WiFi hotkey (Fn+F3) does work, but only if held about 5 seconds. Doh.
