:thanks: in advance!

I have a Windows XP related question that maybe someone can help with.

Any time I come back to my computer and unlock the screen saver my Mozilla Firefox does not work.

It acts like it either can't do DNS lookups or make connections to web sites. If I click any of the sites that had been open they do not respond. I do not get a connection timed out or other error, it just hangs there thinking.

The semi solution is File -> Work offline, followed by File -> Work online

That's enough to give Firefox a kick in the pants and make it start working again.

FYI to others having this problem - You do not need to reboot to fix this issue.

I see my instant messenger come back online when I login, so I think maybe my computer is turning off networking after some period of time in screen saver mode, but other applications on my computer are able to recover after seeing the network is back.

I do not have power saving on except for turning off my monitors. My hard drives stay active. I do not have any form of hibernation enabled.

I have done a bunch of Google reading. Others seem to have had this problem for a long time too.

Any troubleshooting suggestions?

Comments from one of my friends:

If the problem occurs in more than one browser, it could be several things. Power saving, a virus, a faulty or incorrectly configured network driver, etc. Try turning off all power saving features first. Also, make sure your computer has updated drivers and all of the patches and service packs from Microsoft.

My computer has been fixed for several days now.

The solution was to adjust the power settings on my network adapter.

Control Panel -> System, then:

network power settings.JPG

Hardware -> Right Click my Network Adapter and select Properties ->Uncheck the Power Saver options and OK

For whatever reason that response triggered me checking control panel -> power and the power saver options available from the screen saver settings screen. It took longer (and more problems) to get me to spend the time digging deeper and finding the related configuration for the network adapter driver.
