Ok hello.

So I just bought new laptop. Everything was fine, wireless was working fine until now. My wireless started disconnecting. Tried on old laptop - everything cool. On new laptop - it keeps disconnecting.

Where's the problem?

Hello and welcome to Tom's Hardware Forums.

Does it disconnect only when you aren't using it? If so, it could be the power saving settings for the wireless adapter. Check it in Control Panel>Device Manager, right click to expand network adapters, right click the wireless one and go to Properties then Power management.

If it's not that, it may be the channel it's set to receive on if that doesn't match the channel the router is broadcasting over.

Hey. It does disconnect exactly when I'm using it. And it pisses me off. I've called to Samsung and they offering me send it to warranty.. They're kidding me.

I also checked all system updates, only one was affecting my wireless card driver, so I tried restore laptop before this update - but still same ***.

And also what I noticed, when computer is just turned on, wireless works without interruption for like few hours at least. But if laptop is on for more than 2 hours, disconnects starting.

I wonder if you're only being given a short lease on the connection. Can you press your Windows key and R together then in the Open box, type

cmd /k ipconfig /all

including the spaces, then press Enter.

Under the Wireless connection, how long is the Lease?

It says:

Lease Obtained. . . . . . . . . . : 07 October 2012 12:48:35
Lease Expires . . . . . . . . . . : 08 October 2012 12:48:35

By the way, the card model is Atheros AR9485WB-EG Wireless Network adapter.

So I'm guessing it's not that then. I'll go back to the drawing board and hope someone else chips in with a better idea.

Well I just had windows update ( long one, took 50min to finish installation. ) and now it works pretty good. Will see later.

Still keeps disconnecting... If I use more internet and if my laptop is turned on for more than 2 hours it starts disconnecting. Any ideas? thanks.
