Windows 7: Network disconnects when computer sleeps & wont reconnect

Network disconnects when computer sleeps & wont reconnect

Hello. My computer's internet disconnects when I put it to sleep, as if I hit the disconnect button. When I restart it, I have to manually reconnect to my network, and it takes quite a long time. It says "this is taking longer than usual." Before this happened, I had an issue where the internet would disconnect randomly every 20 or so minutes due to a gateway issue. I ran the troubleshooter and it fixed it every time, but it got frustrating. I finally installed some drivers, and the gateway issue was fixed, but this issue presented itself. Thanks in advance.

1. This is a wireless connection issue.

2. AT&T is my ISP.

3. I think I'm using DSL, it's through the phone box.

4. My router is a Netgear router.

5. I use Malwarebytes.


6. Here is my ipconfig.

Hi and Welcome to Seven Forums,

Thank you for all the detail info that you've provided, they are all quite helpful. Your Xirrus snip and ipconfig/all output looks good.
You might want to disable the Power Mode setting of your Wi-Fi adapter in Device Manager see if that helps, here's an image.

Can you also try a wired connection if possible and see if you can replicate the issue?

Thanks for the image. This seems to be the most common solution, although I have tried it on multiple occasions with no luck. I have a few network adapters, though. Should I try the solution you provided on some of the other ones? I only tried it on the first two. Also, would you recommend uninstalling any of them?

Can you please clarify this? You meant other Threads that I've subscribed in.

I'd like you try a wired connection please.

Also, it won't hurt to update your Wi-Fi adapter, you may go to Intel site.

Anybody in your household that's heavily utilizing the bandwidth that you're not aware of?

Can you also post your Speedtest?

What I meant by that was that should I try the Power Management solution on the other Wi-fi adapters?

You're saying that you'd like me to plug a wire to my computer and into the router and then try closing the computer and seeing if it continues it's behavior?

I'll check to see if I can update the drivers via the Intel website.

Nobody is heavily using the network.

Hopefully updating the Intel driver helps.

The Intel Driver Update Utility seems to be stuck on "Analyzing computer." I've tried it on multiple occasions. (I use Google Chrome.) Should I download this? Intel Drivers Download Utility - Free download and software reviews - CNET Download.com

I'd always suggest to best download the driver from the manufacturer site. You may do a manual download by selecting Find by Category, start here and it should be straight forward.

When it asks for a product family, do I say Wireless Networking? If so, do I select Wifi Networks or WiMax?

Edit: Might be easier if you click on Windows Updates, under Optional Updates choose the Intel wireless adapter that you have (if available).

or the hard way:
Please download and install Unknown Device Identifier, this freeware will give you a detail specs of your ethernet adapters. Take a snip of your Network Adapters and post it here. I'll find the correct driver for you.
