Full Router Setup Guide WAN LAN WiFi and Security Settings

A new router is not configured just because the lights are on. The WAN type, the DHCP range, the WiFi security mode and the admin password all need your attention once - do it in the right order and the network simply works for years.

Most people plug in a router, connect to the default WiFi name printed on the sticker, and never open the settings page again. That leaves the internet type on whatever the router guessed, the admin password on admin, and the WiFi on an old security mode. This guide does the whole job properly, in order: WAN first, then LAN and DHCP, then WiFi, then security, then a final test. The menu names differ slightly between brands like TP-Link, D-Link, Netgear, Asus and the ISP routers from Jio or Airtel, but the options themselves are the same everywhere.

1

Connect the Hardware in the Right Order

Before any setting, the cables decide everything. The ISP line - fibre ONT, modem or LAN cable from your provider - goes into the router port labelled WAN or Internet, which is usually a different colour. Your PC connects to any LAN port for the setup, even if you plan to use WiFi later, because a cable connection never drops halfway through a setting change.

  1. Power off both the ISP device and the new router
  2. ISP line into the WAN port, PC into a LAN port
  3. Power on the ISP device first, wait two minutes, then power on the router
  4. Open the admin address from the sticker on the router, usually 192.168.0.1 or 192.168.1.1

Set the WAN Type - PPPoE, Dynamic IP or Static IP

The WAN type tells the router how your ISP expects it to log in. Choosing wrong here is the number one reason a new router shows no internet.

  1. Dynamic IP (DHCP) - the ISP assigns everything automatically. Common with cable and many fibre connections. Nothing to type.
  2. PPPoE - the ISP gave you a username and password, common on DSL and some fibre plans. Type them exactly; they are case sensitive.
  3. Static IP - only if your ISP gave you a written IP address, gateway and DNS. Rare for home plans.

If you are replacing an old router and do not know the type, look at the old router's WAN page or call the ISP - guessing costs more time than asking.

Set the LAN Address and DHCP Range

The LAN side is your private network. The router itself usually sits at 192.168.0.1 or 192.168.1.1, and its DHCP server hands out addresses to every phone and PC.

  1. Leave the LAN IP as it is unless it clashes with the ISP device using the same address
  2. Set a sensible DHCP pool, for example 192.168.0.100 to 192.168.0.199 - that leaves the low numbers free for printers and CCTV cameras you fix later
  3. Optional: set DNS servers such as 1.1.1.1 and 8.8.8.8 if your ISP DNS is slow or unreliable
4

Name the WiFi and Set a Strong Password

You get two bands: 2.4 GHz travels farther through walls, 5 GHz is faster at short range. Give both bands the same name and password and most routers will steer each device to the better band automatically.

  1. Pick a name that does not reveal your name, address or router model
  2. Use a password of at least 12 characters - a short sentence you remember beats random symbols you forget
  3. Set the security mode to WPA2-AES or WPA2/WPA3 mixed. Never use WEP or leave the network open
  4. Turn off WPS in the wireless settings - its PIN mode is a known weak point
5

Change the Admin Password and Check the ISP Router Question

The WiFi password protects your network; the admin password protects the router itself, and the default one is printed in every manual on the internet.

  1. Change the admin login from admin/admin to your own strong password and note it somewhere safe
  2. Make sure Remote Management from the internet is off - the admin page should only open from inside your home
  3. One honest decision: if your ISP already gave you a decent router and you only need better WiFi coverage, adding your own router behind it creates a double NAT problem. Either ask the ISP to put their device in bridge mode, or set your router to Access Point mode
🔴 The honest limit: no setup guide can fix a dead ISP line. If the WAN light stays red after the correct WAN type and a restart of the ISP device, the fault is on the provider side - test the ISP device directly with a cable before changing more settings.
6

Save, Reboot and Test Everything Once

  1. Save or Apply on every page - many routers forget unsaved changes on reboot
  2. Reboot the router once from the System or Maintenance menu
  3. Reconnect your phone to the new WiFi name and open a few websites and one video
  4. Check the Status page: WAN should show Connected with a public IP address
  5. Walk to the farthest room and confirm the signal is usable there - placement problems are easier to fix today than next month

❓ Frequently Asked Questions

I do not know whether my connection is PPPoE or Dynamic IP. How do I find out?

Open the old router's WAN or Internet settings page - the type is written there. If the old router is gone, check any paper or SMS from the ISP with a username and password; that means PPPoE. No credentials anywhere usually means Dynamic IP. When in doubt, the ISP helpline confirms it in one call.

Should the 2.4 GHz and 5 GHz networks have the same name?

Yes, for most homes. One name and one password lets your phone move between bands by itself. Split them only if a smart bulb, camera or other 2.4 GHz-only device refuses to set up, or if you want to force a fixed device like a TV onto 5 GHz permanently.

My ISP gave me a router already. Should I still use my own?

If the ISP router covers your home and you have no special needs, keep it simple and use theirs. Buy your own when WiFi coverage is poor, you need features like guest network or DHCP reservations, or the ISP box is locked down. Then run your router in Access Point mode or put the ISP device in bridge mode to avoid double NAT.
