Hello all,

I have a newer (less than 1 year old) Dell Inspiron 1525 laptop w/ windows vista that has recently (over the last month or so) began disconnecting its wireless connection after about a hour of use. I have a Cisco Linksys Wireless G broadband router that is used by two Inspiron laptops (a 600m [using XP] and the 1525 with the problem) along with a wireless Dell printer. The 600m laptop has no issues with staying connected to the router and networked printer which leads me to think that the problem with the 1525 is with that computer and not the router.

What happens is that the computer connects just fine and stays connected for about an hour before it stops working. This occurs while using the internet. It just stops connecting to websites and needs to be restarted before it will connnect again. Additionally, the connection does not work well with the wireless printer. It either doesn't work at all or information is sent to the printer and a page or two is printed and stops without printing the whole "print job". Sometimes it will stop halfway through a page.

It seems to me that these two issues would be related to the wireless card/modem in some way. I have tried going to Dell Support and found an update for the wireless software which I installed but the disconnection and printer problems continued. I did locate the wireless card slot for this computer but it does not have a card in it. All there is, is a plastic slot filler type of thing in there. So I assume the actual device is internal.

I don't know if this is worth mentioning or not but I have the free versions of ZoneAlarm firewall and AVG AntiVirus installed on both computers. I'm not sure if there may be some access issue or setting that may be causing the problem for the 1525 computer or not. I may have missed placing something important on the "safe" list.

Well I hope that is enough information to get started with. Please let me know if you need any other information to figure things out.

This could be an incompatibility between your router/ISP and Windows Vista. Without the specific error message it's hard to tell tho'
This article explains a workaround for incompatibility issues in Vista networking: http://support.microsoft.com/default.aspx/kb/928233
