Q: After I upgraded my HP Pavilion g7 laptop from Windows 8 to Windows 10, the Wi-Fi quit working.
When I pressed the F12 key that formerly toggled the Wi-Fi on and off, the on-screen menu showed only airplane mode was available, not Wi-Fi. In addition, Wi-Fi is no longer listed in my PC's Network and Sharing Center menu.
I made sure that the PC's Wi-Fi driver software was up to date, and tried some suggested fixes from online forums, but nothing worked. What can I do?

A: Losing Wi-Fi connectivity has been a frequent side effect of upgrading a PC to Windows 10.
The most likely cause is that neither HP nor Microsoft has provided you with the correct Windows 10 software driver for your PC's Wi-Fi device, called a network adapter.
To correct that, download a Windows 10 software driver from Realtek Semiconductor Corp., the manufacturer of the network adapter. Go to tinyurl.com/hmjdmug and scroll down to the headline "Drivers of HP Pavilion Which Are Not Supported Officially by HP for Windows 10." Below that is a list that contains your PC model. Underneath the list, click the word "download" next to "Realtek RTL8188CE 802.11b/g/n Wireless LAN Driver." Double-click the downloaded file to install the software for your Wi-Fi adapter.
HP suggests other solutions, such as resetting your wireless modem by unplugging it, or letting Windows "reinstall" the PC's Wi-Fi network adapter driver software. HP also offers troubleshooting software to identify your PC's problem. See tinyurl.com/oug36oa.
If none of those fixes work, your PC's internal Wi-Fi network adapter may have failed. If so, you can replace it with a $10 to $30 external adapter. These devices, which are often no bigger than a flash drive, fit into one of your PC's USB ports. For some examples, see tinyurl.com/jabufac.
Q: My wife and I own a small vacation rental business, and I send an email to each new guest who's interested in renting a particular property. Later, when another person wants to rent the same property, I call up the original email, make changes to personalize it, then forward it to the new customer.
My problem is that Outlook.com's "sent" mail doesn't show all these emails separately, as I'd prefer. Instead, it shows just one email, which I have to click on to see all the people that I've sent it to over time. How can I fix this?
_Dave Nielsen, Bedford, N.H.
A: The problem is that you've literally sent all of these people the same email file, even though you sent it at different times and with an altered message and recipient address. To the Outlook.com software, it looks as if you've sent a group email to all your prospective customers at once.
The solution is keep a "sent" email containing your standard rental message. Each time you contact a new client, copy and paste that standard message into a newly-created email, then customize the wording and recipient address for your latest client. Outlook.com's "sent" folder will then show that you sent a separate email to each client.
