Hello,I own an Acer Aspire 7720g notebook with Windows Vista Home Premium. I have encountered a problem with the networking side if things.After a few minutes of powering up the notebook the network side seems to disable. Ok now the strange thing is that the network connection icon that is in the system tray still shows as connected (as in the icon picture) but mousing over it brings up nothing. Also when I try to go into the 'Connect To' option or 'Network and Sharing Centre' it will hang and not actually load anything other than a blank screen.The wireless indicator light on my laptop goes off but is not disabled. Pressing my wireless switch will disable and enable the device (well at least it says on the screen that it is doing that) but still it will not connect. It takes a few system restarts before the network becomes stable enough to stay connected.The strange thing is that this happens with a wired setup as well. I have tried updating all the drivers of my laptop, not just the network related ones. It seems to have only started when I upgraded Vista with SP1, though I can not gaurantee this as I upgraded it a few days after I purchased the notebook.I have disabled the 'turn off to save power' option for both wired and wireless. It seems like the whole network part of vista crashes as I can not get into any part of it when this problem occurs.I would appreciate any help that anyone can give.ThanksDavid Whitfield.

Hi David, After you upgrade the system to SP1, the anti-virus, firewall or other security programs may not recognize the new system components and block some of the programs. I suggest that you temporary disable the programs, then check the result. If the issue does not occur, you need to adjust some settings of the security programs. However, if the issue persists after you disabling the programs, I suggest that you temporary uninstall SP1, and then check the result.
