What network cable does a belkin N600 use RJ11or RJ12
Look again. Those "RJ11/RJ12" are not 2-pair/3-pair small Telco jacks but rather the 4-pair lager size found in Telco data com circuits (ancient DS0/T1 technology) and commonly now for Ethernet often referred as Local Area Network, LAN, data communications at 10 up to 1000 Mbps.
An RJ45 is larger and can not fit into an RJ11/RJ12 jack. The smaller RJ11/RJ11 will insert and make contact with the inner pins but if the line is active the Belkin device now has/will have a blown port. Don't!
Your Belkin N600 expects one Ethernet cable from a cable or DSL modem into the WAN or Internet port on the Belkin N600 for link through your carrier to Internet.
A four port gang of Ethernet RJ45 plugs is also present and is where your in-house PCs and Ethernet peripherals plug in. On the OEM website usually there is a colored quick setup guide to help you.
Some OEMs designate a yellow Ethernet wire from cable/DSL/satellite modem to WAN port and blue for internal LAN devices to try to reinforce outside verses after the NAT firewall inside the router for your internal LAN. The signal doesn't care about color it's for you.
The internally generated WiFi or WLAN (wireless LAN) is part of the LAN side but allows WiFi radio connection to client devices.
The 4-pair Ethernet cables have 8 conductors wIth the wire end of the plug to you and the contacts held upwards you will note the four pairs and their colors blue, orange, green and brown each with one conductor of the pair white with the color and then the color solid or more correctly the color with white stripe. Signals are on pins (left to right) 1&2, 3&6. On standard cable both ends are the same - a straight through, for hub to client. A cross-over cable takes 1&2 to 3 &6 on the opposite end and vice versa. This was for client to client or hub to hub connections before auto-sensing ports showed up to make the signals swap if needed automatically found in most equipment today. Some cables from OEMs have the correct physical size and pinouts, but only use the 2 signaling pairs. It is best to use these short distances and preferably away from rf noise like in modem to WAN port connections.
The twists per inch in the cable and interweave determines frequency response which defines CAT 3, CAT5, CAT5e and CAT6 level of Ethernet cables. CAT5 is fine else CAT5e/CAT6. CAT3 is generally considered now for telco use only, but can be pressed into into service short haul. (Won't get the 328 ft rated reliably above 10baseT speeds).
You may run across Ethernet with PoE this means on unused pairs a device like a video camera is fed power as well as data connectivity over its Ethernet connection. Follow directions to put power to the correct location as needed and look for any recommended grounding requirements, especially with antennas.
Prices vary widely depending upon bubble packaging and the store overhead generally $6-$12 for about 6 ft or 2 m.
If you want to make your own then RTFM and understand millage may vary until you get the right tools and parts and practice while adhering to standards. I find it more cost effective to use pre-made & tested cables except if failure at an end then I repair followed by testing to re-qualify the cable to not degrade its use.
OBTW - Generally the USB was for single computer use at lower speeds of earlier service speeds below 3-6 Mbps - usually don't.
