Solved Wifi adapter keeps turning off on Asus laptop

huffman142 · Jun 27, 2014

I have an Asus laptop with a Atheros AR9485 wireless network adapter. I've owned the laptop for a year and a half and never had a problem until the last 6-8 weeks.

The wireless adapter turns itself off randomly. I can be in the middle of something and my connection is gone. I click on troubleshooting and it tells me it is off, so I turn it back on and it will work for a while longer until it decides to do it again.

I have disabled all other network adapters. I have uninstalled the drivers and reinstalled them. I don't know what is causing this. It all started after I hooked up a router (via ethernet) to set it up about 2 months ago. It was only connected for 20 minutes while I set it up, but ever since then my wifi adapter will not stay on. Like I said, it happens when I'm using the computer...not just when it's idle.

Any ideas what I could try?

Thanks,
Scott

Hello,

Does your connection disappear at random times? You might want to take a look at my thread as we have possibly the same problem. If we do, we could help each other when finding the solution.

I have got win 7 64-bit on asus laptop as well.

huffman142 · Jun 27, 2014

Yes, completely random. There's no obvious thing causing it. Sometimes I can use my connection for an hour before it happens, then it can go out 3 or 4 times in a fifteen minute period. It's driving me crazy because I can fill out a form online and if it goes out when I hit send I lose everything! I should have noted that the wifi signal is fine because I have another computer and multiple phones, tablets, and TVs running and they NEVER lose signal.

And I've tried with two different wireless routers and it still happens. It's definitely something with this laptop causing the problem.

You can try going into Device Manager find the problematic wireless device via "Network Adaptors" right click to properties then to the Power Management tab, uncheck the option to allow Windows to turn off this device.

I can't imagine any other reason why it would turn itself off unless it's a hardware problem with the actual device.

huffman142 · Jun 27, 2014

Yes, that box was checked. I fixed it, so we'll see how it works the rest of the day. Thanks!

TheFlie · Jun 27, 2014

You might want to check for ipconfig at command prompt, like me.Check when your lease expires and see if you loose connection at that time. For me it does then..

Further on, i will just reply when i have the cause and solution to my/our problem. Good luck!

So far *crosses fingers* it hasn't happened again since I adjusted the power management option. I'll update again if anything changes.

That setting causes the same problem all the time, driver glitch I believe. :party:

Just one more update in case someone finds this forum in the future. That did fix my issue! It hasn't turned the adapter off since I changed that! Thanks.

Thank you starting this threat, got the same make adaptor and unclicking the power button seems to be working for me too. Was driving me crazy for the last few days with it connecting and disconnecting, just don't know why it started to do it in the first place. I'm also this helps my wireless printer connection as this had also stopped working!

I am having the same problem, tried the power management solution but it has not solved my problem. Any other tips?

MJSOKO · Dec 8, 2014

I'm having the same issue (for a few months now). Three things I have done:

I use the command prompt to "ipconfig/release" then "ipconfig/renew" and that works some of the time.
I have to continually use the wizard to fix my network adapter and that works some of the time.
Reboot the router and restart my computer.

I have tried changing the power management. Just had to redo it -- so not sure how the box got checked again.

What's confusing to me is my wifi seems to be find at home office (all other devices are connected and working fine), however I NEVER had this issue when I'm working at my small retail business office.

I purchased my computer less than a year ago, which makes this even more frustrating! Any other fixes out here?

solved wi-fi problem

had that problem with embedded Wi-fi not working on S300 asus laptop. I had to use USB wireless adapter from Trident and that worked OK. Today I had to open laptop to clear dust clogs in the fan (full-speed fan all the time) and found one of the two antenna cables badly pinched by the screen opening mechanism. I bet that was the original reason for not working, I tried million other options, drivers, updates, etc...
I couldn't repair tiny coax antenna cable, have to buy it somewhere and see if that is going to cure it completely.

Here's how I fixed the problem in Windows 10.

Right click Start Icon. (Lower left.)
Left click Device Manager.
Left click Network Adapters.
Right click the adapter and Properties will appear.
Left click Properties.
Left Click Power Management.
Uncheck this: “Allow the computer to turn off this device to save power.”
(More than 1 adapter – do them all.)

this can be fixed in few simple steps -
1. just check your wireless driver and make sure its updated
2. check the wireless switch and make sure the firewall is not blocking the internet connection for more help you can visit https://www.asus.com/in/support/ . thanks this may help

June 2016 Atheros AR9485

Used JHarpJ from 2010 solution above: Even though it's a six-year-old solution it worked! A few weeks after updating to WINDOWS 10 on my ALTEC laptop my Atheros adapter kept turning itself off every few seconds. I found this old post and turned off ability for Windows to turn off adapter to save power (exactly like it's posted above). It worked. Don't know why it started turning itself off after YEARS of use but the only thing that changed was installing Windows 10. There was no power issue - the laptop was plugged in!
I'm just glad it's fixed!

Hi all, I was fighting this one for last 2-3 weeks. I found the answer satisfying enough on:

Wireless capability keeps turning off - TechSpot Forums

Uninstalled Wireless Console 3 and.. problem gone

so are the fancy pop-up icons
