Hi all, just been given the task of setting up a Vigor 2860n in a small office environment and seemed to have fallen at the first jump the whole office, PCs/printers/nas boxes etc are configured with the 192.168.0.xxx range and the Vigor defaults to the 192.168.1.xxx range out of the box and I cannot find any way to change this, I don't want to reconfigure the whole office.
I have tried for hours and seem to mess it up or get various error messages resulting in having to reset defaults just to get internet back online, I'm sure its easy and hopefully someone will make me look daft

Thanks all

LAN >> General Setup >> LAN1 [Details Page] is where the setup resides!

You first need to connect the new router to a stand alone pc/notebook so the pc sets itself (or you manually set it) to be on 192.168.1.x and you can then access the router on its default address and thereby change it.

OK finally got round to having another go at this, I have found the page LAN>General Setup>LAN1 Details page, set the ip as required and get this message, no idea what to do now.

No message showing up in your post.

the subnet mask did you tried to change instead of the 255.255.255.0 to example 255.255.255.255 or 255.255.0.0 etc ... if will make difference?
