Problems with Westell 7500 Gateway

[blackops1md]

Hi guys I have a problem with a westell 7500 series wireless gateway. Having recently upgraded to the gateway from an old 6100 series modem, I am having some issues keeping computers synced with the gateway. Every time I restart my computer connected to the ethernet portion of the gateway, I must re-enter my default gateway on my computer's ipv4 settings. I have dedicated ip's set up for every computer on the network and all of them have problems recognizing the gateway. Even setting the ipv4 to autodetect the settings, it locks me out of the internet saying it is a public network. I have verified all my settings in the gateway and it is set up for private connections only. Any help that someone could give would be appreciated. Thanks

When you are online, is an IP Address on computer the same IP Address that is on http://www.whatismyip.com/ ?
