In a typical cable-internet system, the coax cable goes into the modem and the ethernet output goes to your router. There may be some way to connect directly to the modem, bypassing the router, but that is not for typical routine usage. Most cable companies configure your modem remotely, so it would be very unusual for you to connect to it and modify the settings. Not impossible, just not normal.Does the router "internet" port connects to the laptop "ethernet" port only for entering the admin settings ???
The "internet" port on the router is the one facing the cable modem. The others are all for the local LAN, as is the wireless LAN. If you want to administer that router, connect to it through wifi or one of those LAN ports. The LAN ports can be more effective if you're making changes to the wifi settings, since you'll have to re-establish a connection every time you change the wifi. It's faster over a hard connection. But you can do (almost?) everything over wireless.The Dell 1184 Wifi router has no Lan ports used. Only Wifi for a surveillance camera.
The way I see it, the router is a distributor. It distributes internet service through the air if you use the pass word and it distributes internet service through its ethernet ports without a pass word.Does the router "internet" port connects to the laptop "ethernet" port only for entering the admin settings ???
It's quite possible your cable modem has a router built-in. In fact it appears that it must, just not a wireless one. That obviously works fine but I'd say your drawing in #8 is the more typical arrangement. My last two cable modems had only a single outlet port for ethernet, clearly meant for a router. But if you can hook directly into the modem, that's fine.The Wifi router is off (unpowered) until needed. The modem manual shows no instructions for using/connecting an external router.
Sorry, I screwed up the formatting when I added a sentence. Fixed now.And,
How is this possible? I did NOT post that last line in the insert below !
That is my case. Previously I had the usual cable modem (Motorola Surfboard) and now we have an Arris Cable Modem TG862 where the cable modem also serves as a gateway as well as a wireless and wired router and also the telephone. Sort of an all in one. So it really comes down to what you have. My Arris and the old Linksys are both available using a local IP address from any browser be it a wired or wireless system. The Linksys is in the loop for some accesible devices I have on there which are web accessible also for screwing around with devices like using an Arduino with the Ethernet shield.It's quite possible your cable modem has a router built-in.

To administer the wireless router, you must be downstream on its LAN. I don't think you can reach through from the WAN side and alter it. That would be a security problem, although as I said, cable companies can do that with your cable modem.
Ok.As in post #8, the modem/gateway/router/whatever is called has Wifi disabled, non-functional.
No external antenna. Only ethernet connectivity and works well.
DHCP is the method that each device gets an Internet Protocol (IP) address. Since you want your devices to find an available address from 0-255 in your sub domain by themselves without assigning one to each.Thank you. In reality, first problem I have is to understand the extensive vomitive letter soup. It drives me crazy forgetting what they meant and what they do two minutes later, finding multiple words for same meaning.
DHCP 'server' is in this case, the modem ? But the router does it also ? And it does on LAN or on wireless, or any ?
