Dell Inspiron with Windows 10 does not connect to WiFi but other devices will

Question

I have a Dell Inspiron Laptop, Windows 10 and it won't connect to the Wi-Fi in my home any more. All other devices (Phones, Blu-ray, Other Laptops) connect without issue. It was connected and working for months, but it just stopped last week for no apparent reason. It is showing the wireless networks but it won't connect to mine (others are blocked going to try a public one today). I have disabled and re-enabled the Network adapter, uninstalled and re-installed it and it still gives me the "Cannot Connect to Network." Can someone help me?

Solution

I also had this problem after I upgraded my wireless network. The answer turned out to be to update the wireless card driver in my PC.

Have you tried rebooting the machine? Not shutting it down and powering up later, an actual reboot...

Have you tried deleting the saved WiFi network profile and then reconnecting to it?

Yes to deleting and reconnecting. And by reboot, do you mean a factory reset or something along those lines?

No, the laptop has had Windows 10 the entire time. The router is pushing the IP address out just fine, as my daughter's blu-ray player, my phone, and her laptop all connect effortlessly to the signal. I had been connected as of last week, and it just stopped working. It sees all the networks, but I can't connect to mine anymore. I will try connecting to another signal. I have already tried powering down everything connected but I will try again.
