Wireless network connection drops off every 15 minutes or so. dv7-1450 running Win7 64 RTM

HP Recommended

So I have another issue with this notebook (dv7-1450) and Windows 7 64. Every 10-15 minutes the wireless network just disconnects and displays as "No Internet Access" in the Network & Sharing center. This is obviously a driver issue. I can resolve by disabling and re-enabling the device, but I can't do this every 10 minutes.

 

After installing Windows 7, Windows installed the "Atheros AR5009 a/g/n Wireless LAN drivers" automatically, but this driver obviously doesn't work well. I searched for a Vista 64 driver on HP's website, and all I could find is a Broadcom Wireless LAN driver, but I don't think this is the right driver either. When I try to install it, I get a warning that the driver is not compatible, then when I continue to install the installations results in an error saying "The device cannot start".

 

So what gives? How can I get this wireless network card working on this notebook? I can't even find any working drivers. Physical network cable works but will NOT be available to use in working environment. Help.

Update (no resolution): After searching Google & HPs other forums, it appears that hundreds of other people are having the same issue with the AR5009 series adapters and 64 bit versions of Windows (Vista or 7). My question is, why would HP sell a computer with a 64 bit processor and 64 bit OS that doesn't fully support 64 bit drivers?

 

Anyway, ufortunately no one seems to have a clear answer/resolution to this issue. Not sure what to do other than take back...

UPDATE (POSSIBLE RESOLUTION): After spending a few hours troubleshooting the network, it appears that the wireless Atheros AR5009 wireless a/b/g/n card built in the notebook doesn't play well with my Linksys WRT300N router when configured in "Mixed [B/G/N] Mode". I changed the mode on the router to "Mixed B/G [Only]" and have maintained a solid wireless connection for over an hour now. Before it wouldn't hold a connection for more than 10 minutes, and was disconnecting from the wireless network every 2, 5 or 10 minutes.

 

Still holding my breath, but leaning towards that as the cause. I'll post update tomorrow...

Thank you. I'll try this if I start having problems again. So far since my last update (changing the settings to B/G only mode on my Linksys WRT300N), it's been working ok. I'm not even sure if I was getting true Wireless N speed to begin with.

Here's something you might check on.

Since you're using wireless, it might be a wireless security issue.  I see this all the time with 64 bit operating systems.

Check your security type, if you are using WEP, that's your problem.  64 bit operating system do not work well with WEP.

Change to WPA and you'll be fine.

Thank you. But I actually haven't used WEP in a long time. WPA Personal is the current method.

You should write a macro to re-install the driver every 9 minutes.

Daniel,

 

How is that driver installed in Win 7 Ultimate 64? I downloaded a utility to sign the driver but when I try to install it, I'm told my present driver is the most current.  I'm befuddled.
