Hello
I am trying the setup a Cisco 2801 router behind my Comcast router. I do not want to put the Comcast device in bridge mode, I want to use the wireless from it. I am not sure what I am doing wrong. This setup worked fine when I was using an old Linksys router in place of the 2801 router.

PC info

Subnet Address 255.255.255.0
Default Gateway 192.168.1.1

This is for a lab environment, so when I mess up the wireless still works in the rest of the house. I have a webserver at 192.168.1.150 that worked without any issue using the old Linksys and double NAT
Thanks in advance
