Since at least November, there has to be lingering problems with my Inspiron 3537's internet capability.
Some context: I inherited the laptop from someone else (that laptop is more than half a decade old), and I installed Windows 10. After a couple of days, I updated some drivers (particularly the BIOS, graphics, and the wireless drivers), and then the problems started.
Here is what I had done so far to get the internet in my laptop working correctly again:
Which leads me to this conclusion; there is something wrong with the internet driver(s). The driver's(s') getting a series of Code 12's and after that, when I restart my laptop, the driver(s) in question is/are nowhere to be found in the Device Manager; the driver(s) keep(s) disappearing. It could be either a potential driver software or hardware issue.
Try the following page. It is possible that another hardware device is conflicting with the wifi card. In a pinch you could try a USB wifi device. I had one on my old Latitude and it worked far better than the wifi card that was internal.
