Inspiron 15R SE 7520 - no wifi available when I switch to battery power
When I remove charger all wifi signals lost. I need to plug it back in and restart. Sometimes troubleshooting works and points to a fix in network adapter but only aftter mains power restored. Any suggestions? I tried to do Dell Diagnostics but after downloading program then installing Dell System Detect nothing happens (Windows 10).

Hi,
I've had a very helpful reply from a contributor (thanks Regedit32) to a Windows 10 forum. Early days yet but the suggested action appears to have resolved the problem. My laptop has been running on battery for nearly 2 hours and the wifi connection has not dropped out. Previously, wifi would have dropped within 10 secs of going from mains to battery.
Here's what worked for me:
— Wireless Adapter Settings
— Power Saving Mode
—Setting: A setting will be present here
In my case, the setting prior to change was Medium Power Saving. That appears to have been the culprit.
Good luck!

Hi,
Have you tried adjusting the power settings for the wireless adapter itself? If you search for Device Manager in Windows 10, then open up the Network Adapters category in Device Manager. Right click on the listing for the wireless adapter and select "Properties". You should see a tab for Power Management and, depending on the wireless card and driver installed, options to "Allow the computer to turn off this device to save power". Make sure that is unchecked.
You don't mention which wireless card you have in the system, or the driver version that is currently installed, so there may be other options you'll want to test to see if changing them will help.
To better help me troubleshoot this issue please tell me which wireless card you have in the system, the current driver version. Also, please right click on my Dell Todd username and send me a private message with the Dell Service Tag of your Inspiron 15R 7520. Please keep all troubleshooting discussions here on this public thread so that others, with the same questions, can see what is done to resolve the problem.
Thank you,
Todd

Hi Todd,
I also have a Dell Inspiron 7520 15R SE laptop which has the same problem as described by marieam.
The Service Tag is DPPC0X1.
The wireless adapter is an Intel Centrino Wireless-N 2230.
"Allow the computer to turn off this device ..... " is unchecked.
The laptop has been upgraded to Windows 10. I can't be certain but I think the problem has only existed since the upgrade.
Were you able to resolve the problem for marieam? If so, I'd be grateful if you'd let me know the answer.

Hi Mondeoman
Glad you have chimed in. I have heard nothing. We have 3 Dell laptops in our household and the two that have the 10.1 upgrade have misbehaved ever since the upgrade particularly when plugging unplugging from a power supply. We either have to troubleshoot network adapter or if that fails restart the computer. The laptop with Windows 7 has no issues whatsoever so it is not our internet connection. I have uninstalled/reinstalled downloaded drivers etc. etc. but remain convinced it is a Windows 10 issue.
Laptops with issues are
Inspiron 15R SE 7520- wireless adapter Intel(R) Centrino(R) Wireless-N 2230.
Inspiron 3537 - Dell Wireless-N 1705
Look forward to some assistance.

Hi Michael Shelton
Sorry for the delay but wanted to test it out at various locations over Easter and have to say THANK YOU. All is well. One Dell laptop that moves around quite a bit has had to do a couple of troubleshootings on Network adapter to repair but other than that all good.
Only information I can add is that we could not find 'Balanced' option first up, but at a closer look this was under 'Show Additional Plans'.
Your help is much appreciated.
