I have a Toshiba Satellite C55t-C5300. For the last two weeks, I have been unable to connect to any Wi-Fi network. I only have internet access when I connect my laptop to my phone via the mobile hotspot. When I press the Wi-Fi button it says "No Wi-Fi networks found" and when I run a diagnostic, the troubleshooter says there's a "Problem with the wireless adapter or access point". I have tried resetting, disabling, uninstalling, and re-installing the Broadcom 802.11n Network Adapter several times, but it still doesn't work. I have disabled my anti-virus software, I'm not using a VPN. I have run out of options and I have no money to have the computer looked at and "repaired". I am using Windows 10.

If anyone can offer any assistance, please do! I am desperate for answers!

Yes I've seen that page. No help. That's where I reinstalled the driver from. It's definitely Broadcom on my device, but I was thinking of maybe uninstalling and trying a different one? Not sure if that'll mess me up or not.

Save the driver you currently have on a USB stick. Then select "roll back driver" and see what version it loads.
Try it and see if it improves anything.

After reinstalling and enabling/disabling and it still not working, I would say your adapter has failed/died. "No networks found" likely indicates it has malfunctioned as well.

Your best bet is to simply install a USB wireless adapter, however you do have the option, if you're comfortable opening the laptop's rear panel of replacing the built-in wireless access card.
