My roommate bought a new DELL laptop, operated by Windows 10. In the three weeks he's had it, it's online then goes offline (and this repeatedly): when he goes from one e-mail to another, when he engages in a financial transaction, when he opens a new webpage, etc. He does the basic rebooting, as prescribed in the article whose link is attached. His pc and my older DELL and Apple PowerBook are all on Wifi. My two NEVER go offline.
If you know of similar issues, are you aware that it's because Microsoft fixed one problem but created this new one I am describing?
Any information you might provide would be appreciated.
