We just got comcast at work which replaced our verizon internet and phones. So far we love the system and it's way faster. Everything seems great.
I do need one thing though and I don't think customer support understood what I was asking.
We have about 15 computers in our offices give or take.
Here is how our office is "wired" right now.
We have the comcast "modem/router" which is the SMCD3G-CCR downstairs in room "A".
The SMCD3G connects to a Linksys wireless router via ethernet in room "A". That Linksys router connects upstairs into a 24 port DLINK switch in room "B". From that switch it goes into room "C" and connects to an 8 port netgear switch which has 3 computers and a big xerox plotter printer (print system 510dp) connected to it..
My Xerox plotter is connected to an 8 port netgear switch in room C. In order for everything to work right that plotter needs a fixed ip address (I assume an interal ip address assigned by the comcast modem/router unit).
Right now I have the xerox plotter set to 10.1.10.63
I want to ensure that no other computers can get that IP address assigned to them.
After loggin into the router and looking all the computers are below 10.1.10.35 but I would just like to be able to set it up in the comcast SMCD3G that the address 10.1.10.63 cannot be assigned by DHCP. I have manually assigned it to the printer which I did by physically changing the settings on the printer and set it up on that IP address when I installed the driver on the windows 7 machines that will print to the plotter.
Is there any way I can do that? I basically want to have the peice of mind that the comcast modem/router will not assign the printers address of 10.1.10.63 to any of the office computers.
If I can do this, that should be something that I only have to do on the comcast box. I shouldn't have to do that on the Linksys router or mess with the two switches?
