I have a Cisco 871w which I am using as my router for internet access. It is connected to my cable modem. My outside local interface is Fast Ethernet 4. While my inside interfaces are Fast Ethernet 0 - 3. The subnet for that is 192.168.1.0 255.255.255.0. My wifi subnet is 192.168.2.0 255.255.255.0.
My goal is to have 1 subnet instead of 2. I am not sure how to approach this without bringing down my internet.
Any help would be appreciated!
Here is my config:

If I have not misread, but why dont you simply put the LAN ports on the same vlan 1? If that is possible, then have the end devices that belong to VLAN 2 rebooted/DHCP renewed.
No/yes?!
