Greetings, I have a Cisco 871 wireless router and am having problems configuring it to act as a Wireless Access Point for my small internal network using Microsoft Small Business Server 2003. I am trying to set up one client access via wireless. Using Cisco’s SDM Express, when trying to change the LAN Interface IP from its default to I keep receiving an error: connection lost.

Is anyone familiar with the steps to accomplish this. Also, I’m a little uncertain under the Wireless section for Router which IP Protocol IP Address and Sub to use for Radio0-802.11G. And finally, what IP to use for WPA's RADIUS server setting. Thank you for any suggestions. Richard

    If this problem continues, you may want to consider flashing the firmware. Recently I was setting up a new WAP and I had similar problems as well as interference on networking switches (still confused about that one). I flashed the firmware and the problems went away.
