My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
Which version of windows is on the Toshiba Laptop? 10,8,7,etc...
okay, thank you.
First make sure that the fn key that enables wifi has not been turned off. It will be at the top of the keyboard and have a wifi icon on it, some have a light indicating on or off.
If it is on, then Right click on the Windows Start menu icon,
then click on device manager,
then click on the network adapters to expand the list,
then right click on the wireless adapter and choose uninstall, then reboot the computer.
The Toshiba will automatically reinstall the wireless adapter with fresh settings and drivers on the reboot,
when the computer powers back on check for wifi.
Let me know the results please.
do you see one that says wireless adapter?
okay, try uninstalling the realtek family controller, then reboot and check.
did that work?
okay, what is the Toshiba model number?
the Model and Serial number can be found on the bottom case of the Laptop as either a printed sticker or laser etched into the cover
okay, we will need to troubleshoot further and maybe install drivers for the wireless adapter.
Do you have an ethernet cable that you can connect tot he laptop and get it connected to internet?
okay, try this next please>
Wait for your PC to restart and see if that fixes the problem.
okay, the next option will be to install the wireless network adapter driver. We will need to get it connected to the internet for that.
then go to your email on that computer and follow the steps I send you please.
Click on the blue link below and allow the remote session to download then click on the elsinore remote session download and allow the program to run please>
enter the screen password ***** the Toshiba please.
let me know if the restore worked please.
it should be finishing soon.
okay, this sounds like you will need to do a restore of the operating system. There are some missing or glitched system files. If you have important documents you will need to back those up to a flash drive and then restore the operating system. You can try the first reset option which is >
Keep my files
To get started, go to Settings > Update & security > Reset this PC > Get started and choose an option
If the first option fails then you will need to back up any files that you want to save.
