UNSOLVED
Intermittent wireless failure
I have an XPS L502X about 9 months old, running Win7Pro 64. Several times each day my wireless connection goes down, and needs to to have the wireless adapter (Intel Centrino Advanced N6230) reset, after which time the systems works fine again for several hours before going down again. I have cable internet and a DLink 645 wireless router. All the drivers are up to date for both the router and the laptop. The Intel Proset wireless tools diagnostic does not indicate any problems. The wireless signal (set at channel 11) seems quite strong. I see there have been some problems with McAfee Security Center reported in other forums and wonder if it might be that.
The Windows Nettwork Diagnostic report is attached.
I'd be grateful for any help.

Fred,
Go to Drivers & Downloads enter your service tag number, then select your operating system. Under Network, download and install the latest drivers.
Try these tweaks....
Start, control panel, device manager. Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.
Go to the power options, and changed the Wireless Adapter Setting, from Maximum Power Setting to Maximum Performance.

Hi Rick
I already have all the latest drivers for my laptop. I have however made the adjustment for the power and the wireless adapter. I should say that I almost always have the laptop on mains power.
I will let you know how I go with your changes.
Thanks
Fred

I have had two adapter failures since setting the new settings you gave me. Other suggestions?

Hi Rick
I am not sure what I am looking at. If you mean item labelled "4" then it appears to be a closed port with a "dot" of plastic on it. I don't have anything in it.

Fred,
Look at page 30 in the Dell L502x Manual and check to see that the antenna wires are on correctly.

Fred,
Channels 1, 6 or 11 should be the best channels to use. I use channel 11.

Fred,
If you recently installed/reinstalled the operating system, did you install the drivers in order? How to Download and Install Drivers in the Correct Order
Let's first try using these Recommended Wireless Router Settings and use channel 11.
You can go to Drivers & Downloads enter your service tag, then select your operating system. Download the drivers for your adapter and save it to your desktop.
Make a system restore point.
Start, control panel, device manager, network adapters, right click on your network adapter, left click uninstall. Tell it to remove the drivers and software.
Restart your computer. When you log in, the new hardware wizard will try to install the adapter but fail. Use the drivers saved to the desktop to install..
You can also try tilting the computer on the left side and see if your signal increases.

Fred,
In theory, the higher the frequency, the smaller the antenna
So the higher channels should work better with the antenna size. The lower channels need a larger antenna. Channels 1, 6 or 11 work for many wireless devices, like usb adapters, printers, game systems, etc.
The speed for now will be the slower speeds but trying to see if you keep connected. Once you keep connected, if you don't use wireless devices, like printers, cell phones, etc..., you can then try going to WPA2-PSK(TKIP) Security. If you stay connected, then try WPA-AES, then WPA2-AES, these are the fastest connections. But if you don't stay connected, then the faster speeds don't mean anything.
