Hi, and thank you for your question.
First off, let's check if your Toshiba laptop comes built in with a working internal WIFI card. Please click on the Start button, and then type in device manager in the search field and press ENTER.
In the Device Manager, double-click on "Network Adapters" - do you see any WIFI device listed there?
Please reply at the box below, and then we will continue further.
PS: Please do not accept any remote assistance offer (simply "X" it out) if it shows up on this page; it's sent out automatically by our site, and not by me. We do not need to do a remote session for your issue; I'll reply back to you below now.
No issues; you may get back to this page anytime later on, through your emails received from JustAnswer. Thank you.
