I just bought am Inspiron 600M with the Intel Centrino  embedded wireless and WinXP.  I am using Comcast High Speed for Ethernet connection to internet.  I do not use any proxy settings or scripts.  This works fine.  I uninstalled embedded AOL and MSN browsers because they are no use to me.  When I use my wireless card, I authenticate fine, and connect to my Access Point without incident.  Howver, when I launch IE, it tries to detect proxy settings, and eventually fails to load my home page.  When I go to connections in Interent Options, under the LAN settings, the "Automatically detect settings" box is checked off.  I clear this and I am able to browse the interent through IE.  If I reboot or power down, and then go back to try and use IE, the "Automatically detect settings" box is checked off again?  This does not happen if I use the ethernet connection.  They are connecting to the same router/AP, but have different IP addresses assigned through DHCP.  I do not have any @home software installed.  This is a fresh Dell build.  I tried to go the workaround I found in previous postings to do the following from the run command:

regsvr32 /u ahiehelp.dll

The only problem is that this fails because this dll is not located on my laptop.  I have searched all hidden and system files, as well as the registry.  I was wondering if anyone had any ideas, or the registry key I need to modify to make this go away.  I am sure that it is probably some left behind file or registry key from AOL or MSN, or maybe a Dell setting.  With WinXP, you can have more than one internet connection by using the interface metrics and assigning priorities.  The same setup works flawlessly on my IBM Thinkpad T30.  Microsoft does not have any tech tips on this issue, and the Dell laptop keeps behaving like this whenever the wireless connection is turned on upon startup or restart..  Please help as this is very annoying.
