Adding additional wireless router or access point to network
I want to add an additional wireless router or ap to our network to add more coverage to our wireless users. It will be like overlapping the coverage. Right now we have a domain with a wireless router acting as a pass through to our dhcp server on the network. Our wireless users get an ip from our dhcp on our server and access data on the domain. I want to know do I need to use an wireless AP to add another wireless device to our domain network and if so do I set it to use the same channel or different channel? Will I give the new wireless ap the exiting SSID and WEP key for this to work properly? Also will the wireless users keep the same ip or will the get another ip if they switch from one wireless device to another. I would like for it to be a smooth transition from one wireless router to another if possible eliminating downtime or a hickup in network connectivity. Thanks for your help in advance.
