The Router's Input

Depending on the Internet Service Provider (ISP) you currently use the services of, there are several types of connection inputs that can be tethered to your Router.

1 RJ11 Telephone Line

These connections use the typical Telephone line. To quickly understand what an RJ11 Telephone line looks like, simply walk up to your Landline handset and pull out the wire connecting it to telephone network.

Service providers who currently offer RJ11 Internet Connections include:

  • 1: Mahanagar Telephone Nigam Ltd.(MTNL)
  • 2: Bharat Sanchar Nigam Limited (BSNL)
  • 3: Airtel
2 RJ45 Ethernet Cable

These connections are not to be confused with the RJ11. To Keep things simpler, always remember that the RJ11 connector is smaller than the RJ45. If you can connect your connector to your laptop/desktop in the LAN port and get Internet access its a RJ45 Connector! Standardised as the IEC 60603-7-8P8C modular connector, the RJ45 has eight conductor present, as opposed to the RJ11s four conductor.

Service providers who currently offer RJ11 Internet Connections include:

  • 1: Airtel Fibernet
  • 2: Reliance
  • 3: Hathway
  • 4: Act
  • 5: You Broadband
  • 6: Spectranet

Routers with a USB port enable the connection of USB Internet Dongles and Data Cards. Some routers available today include USB ports that enable users to connect a Data Card/Dongles.

Service providers who currently offer RJ11 Internet connections include:

  • 1: Airtel
  • 2: Reliance
  • 3: Tata Photon
  • 4: MTS
  • 5: Vodafone
4 SIM Cards

To further boost Internet Connectivity, many Routers today support SIM Cards. This enables users to connect the router to a wireless 3G Network, offering faster Internet speeds. Besides this, routers sporting SIM Card slots also support 4G Connectivity and CDMA/EVDO SIM Cards. Routers with input connections like these are  particularly better for use in areas where Ethernet broadband network aren't available.

How does the Router connect to your Devices?

Routers may use either Ethernet, WI-FI or both to connect to your devices.

1 Ethernet/LAN (Wired)

Routers using Ethernet connectivity can connect to devices using RJ45 cables (commonly known as LAN cables). This type of connectivity is suitable for stationary devices such as Desktop PCs, Smart TVs, Network Drives, etc. The area that these devices can cover is limited to the length of the cable (although maximum distance without signal loss is 100 meters). The number of devices that can connect is equal to the number of Ethernet ports available on the Router. Typically Router will have either 1 or 4 Ethernet Ports.

2 WI-FI (Wireless)

WI-FI Routers can connect to any device that has WI-FI connectivity. It is suitable for devices that are mobile in nature, such as Cellphones, Laptops, Tablets, Game Consoles, etc. The area that can be covered depends on various factors such as the Frequency Band the routers operates at, the WI-FI channel, number of Antennas on the Router and various physical elements are the ones on which the router is operating in (such as walls and other barriers). The max. number of devices that can connect to a WI-FI Router is 255 (although this can be limited to a smaller number by changing the routers settings. Check the router’s manual to change these settings).
