Networking novice here, so please pardon the relative lack of knowledge in this matter.
I recently signed up with Comcast Business class, and have received an SMC modem/router without wireless built-in. I'm trying to set up an office network, so that I can have some devices wired into the modem/router, while others connect wireless to the same network through my own linksys WRT160N.
The SMC has 4 available ports in the back.
Here is the setup:
SMC Port 1 --> Main PC
SMC Port 2 --> Samsung printer/copier/fax
SMC Port 3 --> Internet Port of Linksys WRT160N --> various wireless devices
SMC Port 4 --> Obi202 --> Phone
PC can see the printer on the network. However, the wireless devices connected through Linksys WRT160N are not on the main network.
The SMC modem/router has an IP of 192.168.0.1 and I am able to access this through the PC browser. The range of assignable DHCP addresses is 50 through 199.
The PC, Printer and the Obi all have addresses within this range.
The Linksys WRT160N, however, has an IP of 192.168.1.1, and DHCP is enabled. Devices connecting through are presumably in the 192.168.1.xxx range. Haven't checked though.
1. Is it okay for the devices that are hardwired to the SMC modem/router to be within that assignable range, or should they be assigned outside that range? What is the difference? If they should be outside, how do I change that?
The DHCP assignable range between 50 and 199 means that the SMC router's DHCP function will assign devices an IP address some where between 192.168.0.50 and 192.168.0.199. So, for example, a device attached to the SMC router will NOT be assign a dynamic IP address of 192.168.0.45 since that in not in the range of IP address "set aside" for the DHCP server.
The purpose, generally, behind this feature to is to leave some IP addresses "unavailable" to the DHCP to assign as dynamic IP addresses so that those IP address could be used as a static IP address.
More than likely, in your case, you don't need static IP addresses for any thing. So, end result is that it is not something you likely have to worry about.
2. How do I get the Linksys wireless router to become a part of the same network as the main SMC modem/router? I read something about disabling the DHCP etc., but do need specifics so I don't go doing the wrong thing.
Basically, follow the instructions for the "LAN to LAN" in the link that czarboom
provided. That should keep everything in the 192.168.0.xxx range of the SMC router.
The other option is to do the "LAN to WAN" instructions and just have all your wired devices connect to the Linksys (I believe this is what czarboom
was suggesting). Then all the devices will be in the 192.168.1.xxx range assigned by the Linksys router. This method does put everything behind a "double NAT router". Generally speaking, that is not a huge deal, but it can potentially slow your Internet connection down (I have read reports from some people finding that removing the second router sped up their connection). The potential advantage of this approach is that you can allow guests to connect directly to the SMC, but they will not "see" your stuff that is "behind" the Linksys router.
3. Comcast business also has modem/router combos with wireless built-in. Would it be better for someone like me to simply ask them to exchange it to one of those devices, so I don't have to mess with the wireless router on my own?
Any help or advice I can get on these issues will be greatly appreciated.
I would say it all depends on your tolerance for dealing with tech. If you just hate dealing with computer/tech, then it might be better to just get a router/modem combo with WiFi from Comcast. If you are open to dealing with tech, but just lack experience, then I don't see a reason to get a combo router/modem from Comcast with WiFi…you should be able to get what you have to work with help as needed.
Personally, I don't like combo routers/modem. I like to have a dedicated modem and router that I pick myself. But that is just me.
