Okay, took it out and it works just fine without it. I had this working before, but couldn't remember the settings. I knew it was something simple. I had other suggestions in private email from well meaning people, but they were a lot of work. I wasn't about to go through and change my entire network to a different range just for the 5 minutes it takes to log in to the router so I can change its address. Even though I had searched and not found the answer, I was sure it was only a minute or two of work if I knew what to do. > I also needed to configure devices that had distinct ip address > values by default.

I will be looking into that, but it'll be later in the week before I have time to try it. Thanks! Hal -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
