In Safe mode, very minimal drivers are loaded. It is only operational enough to allow you to dig yourself out of trouble.
If you need to connect to the Internet use the normal startup, of use the Safe mode that says you can also run with networking.
It might be a simple solution, but my computer can seem to access the internet. My cable modem works (i am typing this on a wireless connect on a tablet) and I have a secondary computer plugged in to the modem as well, and the computer was able to get online. is there something in the start-up in safe mode that I should be looking at? thanks
