Why does my computer disconnect from wifi each night?

We'd be happy to help you with your Wi-Fi concerns, WileECoyoteSr.

You can also try to restart your gateway via:

1. Unplug the power cord from the back of your gateway or modem. If you have: 
   
   • An internal battery backup, remove it
   • DSL, unplug the phone cord from your modem or gateway
2. Wait 20 seconds.
3. Put the internal battery back in if you have one. 
4. Plug the power cord back in. If you have DSL service, reconnect the phone cord.
5. Wait for the gateway or modem to restart and your Broadband light to turn solid green. This can take up to 10 minutes.

Does all your other devices connect properly on your Wi-Fi? By answering this it helps us narrow down what's causing your PC to disconnect from Wi-Fi.

Doesn't really help. It wasn't a cache or history issue. UPDATE: While trying to get my wifi to connect I typed my question above in the Yahoo Secure Search address bar (installed when I installed McAfee) and magically the VPN opened a Yahoo search. (During McAfee install I elected to turn on VPN) I didn't get the normal wifi icon on my bottom of screen, open program bar, but I got to go wherever I wanted on the internet??? No where in the AT&T information does it tell the new AT&T customer that the VPN actually replaces the generic wifi symbol that looks like a radiated radar signal (or drive-in theatre parking lot, as my wife called it) with the symbol of a computer monitor with a square in the top left corner. I can only conclude that my first month in trying to connect through the name of my wifi connection (and only consider it success if I got the generic wifi icon) was not required and may even have bypassed the benefits of VPN connection. I think I've read everything on the AT&T "internet" webpage and the way in which someone new to VPN like me connects and uses VPN is completely lacking. I just hope by clicking on the Chrome ball that gets my internet open and just typing my question or website address in the Yahoo Secure Search address bar is how I'm supposed to securely use a VPN. If there is a link to a Dummies Guide to AT&T VPN, please send it to me. And thanks for attempting to answer my question.

Thanks for that update, @WileECoyoteSr!

Just to confirm, are you able to connect to the Wi-Fi outside the VPN? This will help us to determine if the issue is with our equipment, or if there's something going on with the VPN you're using.

For any questions regarding the VPN that was provided by the McAfee Internet Security Suite, we recommend that you contact McAfee support, as they are best equipped to handle any concerns you may have regarding the VPN.

We look forward to hearing back from you!

Yes. I am able to connect with the AT&T wifi outside of VPN use. It just surprised me that since I installed the McAfee security suite provided by At&T that each morning my wifi connection on my home office computer was offline and I had to ask Windows Settings a number of times before it would connect to my wifi. BUT THEN, I somehow forgot to even check to see if my computer screen indicated a wifi connection, and typed an address into the Yahoo Secure Search that McAfee VPN used to replace my Google Chrome search bar, and my computer went online and found what I wanted. As I sit here, in that operating mode now, I have no wifi internet connection, but I have McAfee VPN internet access - which, I guess, is what is preferred since that would be more secure. 

I think I'll ask McAfee's Yahoo Secure Search for "VPN for DUMMIES"
