Inspiron 5482 Wifi keeps dropping
Hi, Just wondered if I could get some help - I've tried everything to work out why my WiFi keeps sporadically dropping out on my laptop. All other devices in my property that my friends own haven't found an issues. I own an Inspiron 5482 laptop with an Intel Wireless AC 9560. Have tried various online suggestions, installed the latest drivers, but nothing seems to work. I often get the dns_probe_finished_no_internet error so I've tried all the DNS solutions like pointing to a different DNS address renewing the IP etc. etc. but having little joy. Typically as I'm typing now the WiFi connection is fine but it comes and goes. Any tips appreciated - many thanks. Richard

Do not change any drivers. Those must come from Dell since they are customized for your computer. That means no Intel drivers or AMD or any other manufacturer. Get all the original drivers here-

Make sure Power Management is not allowed to turn off the network card to save power. Open Device Manager to check that setting.

Thanks - the WiFi dropping out has been a problem ever since I had the laptop, but I'm now wondering if it's simply a vagary of my WiFi at home as it only seems to happen on my laptop at home.

I have the same Dell laptop model. I have had it over a year no problem. Just recently both Chrome and Explorer lose their connection after 2 - 5 minutes after restarting. The laptop itself shows that it still has connection. All other items in the house are getting connection fine. The only way I can get it to work is to restart over and over again. I tried to check the Power Management fix described above and cannot find where or how to do this. Surely mine is the same as yours?? Please provide more detail so I can repair mine, or any other known fixes for this. Please, Thank you....
