we are giong from satelitte to comcast....with comcast there ip's start with
10.0.0.6 etc or something close to that

I have the satelitte box go into a 4 port router then to a switch then to the pc's.....all we are changing is the first box giong from satelitte to a cable box....my question is to i have to chnage the 4 port router ip?  I think I can leave it alone, even though the satelite to cable box conversion changes ip's?(you go from 192.168.0.1 to 10.0.0.1...will the 4 port router still work leaving it at 192.168.1.2? 

 or does the order have to be sequential....sat box 192.168.0.1 to 4 port router 192.168.1.2 to pc's   versus   cable box 10.0.0.1 to 4 port router 192.168.1.2 to pc's?

PLEASE HELP GUYS IM TRYING TO MINIMIZE DOWNTIME

As ong as COMCAST is setup to use DHCP you should not have to do anything other then reboot your router once attached to the new "modem".  The function of the router is to "route" from one network to another.  So it will continue to route from you Private network (192.x.x.x) to the 10.x.x.x... 

I've never worked with comcast so can't confirm the config for that part.

Comcast is 99.999% likely to be configured as DHCP also, they make you pay extra for static

I concur with Trident, from the info above it looks like it will just be a matter of unplugging the cat5 cable from the satellite and plugging in the one from the cable modem and then power-cycling the router. Should not need to change any of the 'inside' network settings (192.168.x.x).

Possibly Comcast may want to know your Router's MAC address, but it should be printed on a sticker on the router's belly. no biggie.
