I have a dell inspiron 15r 5521. I am facing issues with the network driver. Currently my wifi is working properly, but after few hours it stops working. A small yellow sign comes on the wifi icon. When i dicsonnect the wifi and try to reconnect, I cannot find any wifi networks to connect with. I have to restart my laptop every time this happens. During the restart it shows a blue screen stating power_state_driver_failure. I have tried to uninstall the network driver and re install it. In the network panel my ethernet port shows disconnected. I have been facing this issue for last 1 month. Kindly help.
For the BSOD, download and install Resplendence Software - WhoCrashed then click on analyze. Post back the information.
Try these tweaks....
Start, control panel, device manager. Click on Network and then right click on your network adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.
Go to the power options, and changed the Wireless Adapter Setting, from Maximum Power Setting to Maximum Performance.
Thank your for the suggestion.
I tried to make the changes as suggested by you. But still there is no change. The wifi stops working and have to restart the laptop inorder to fix the problem.
I could not download the whOcrashed software. Can you suggest me some other link or some other software.
Go to Dell PC Diagnostics click on advanced, then click on symptoms. Click on the Blue Screen analyzer.
Here are the screen shots.
This is what happens.
When I disconnect the wifi then this sign comes and no network is available. I have to run troubleshoot.
When I run trouble shoot this is what I get.
These are the results of the troubleshoot then i have to restart my laptop and again run troubleshoot and my wifi starts working.
