Unable to connect to other wireless connections after sleep.

Jump to solution

I had a new problem crop up on my Dell Precision 5510 laptop a couple months ago.  I cannot identify anything that changed around the time the problem started but currently, anytime my laptop goes to sleep, when it comes back from sleep, it is not able to connect to any other/new wireless networks. 

What I mean is that it will connect to the network it was on before sleep but no other networks.  I put my laptop to sleep (and have for 2 years now) when I move from my home office to my work office and now when I wake up at the new location, I get the dreaded "Not Connected - Connections Available" notice on my WiFi.  However, I am not able to connect to any wireless networks till I restart the laptop and then it connects fine till it sleeps again.

I could not find similar posts that just started all of the sudden and that tied to sleep mode.  I connect fine anytime I boot up fresh or restart no matter what network I am at/on at the time but when I sleep and move networks, the WiFi seems to be lobotomized.

Running:

Windows 10 Pro

Vipre InternetSecurity 2016 with latest updates

Latest Dell WiFi, Bluetooth, and Gig-E drivers installed

 

I have my battery power saver set to "Maximum Performance" on battery and on plug for my WiFi adapter so it never sleeps just in case that was a problem.  Also, when the problem started, I had not made any manual changes to my system software or hardware.

I have tried to ipconfig /release ... /renew and have tried disabling and reenabling the wireless device but nothing seems to clear the problem till I restart the laptop and then everything is fine till I sleep again.

Thank you in advance for any suggestions or feedback,

Phil

Thank you again Jessie, I'm accepting the solution as a possible fix as I was able to connect to both my home and work networks without physically going through a restart on my laptop now.  I find it odd that prior to this change, after a sleep and wake-up event, my WiFi icon would still show up in my system tray as if nothing was wrong but if you moused over the icon, it would state "Not connected - connections available".  Though no red "X" ever showed up and if you clicked on the WiFi icon, the list of WiFi SSIDs would never show up. 

Now, after preventing my computer from turning off the network WiFi card, I have noticed a different problem.  I can connect between networks just fine but when I put the computer to sleep manually, the power LED stays on for 5-10 minutes before finally going off where it used to only be on for a few seconds.  I'm wondering if something is waiting for a time out before the power LED finally goes out.  I also noticed that in the 2 tests I ran when going between work and home today and both times selecting "Sleep" for the laptop, all my open programs (Outlook, PowerPoint, and a File Explorer window) were all closed when I fired the computer up again almost as if the computer shut down instead of sleep.  I'm still diagnosing this new issue but for now, my connecting to networks has been resolved.

 

Thank you again,

Phil
