DD-WRT hotspot setup procedure

Requirements

First, you need an internet connection. There is no restriction about the kind of internet connection, but you must have an ethernet plug to connect..

If you don't have a compatible router, you can buy one that is already flashed.

Disclaimer

Flashing DD-WRT into your router is an easy task. However, please note that incorrect flashing procedure can brick your router and might void its warranty.

WorldSpot.net cannot be held responsible to whatever occurs to your router.

If you don't want to take the risk of flashing your router, you can buy one that is already DD-WRT flashed.

Flashing DD-WRT

First you have to make sure that your router is supported and has at least 4mb of flash.

Supported routers with 2Mb flashes can't actually run chillispot, and can't be used for a hotspot. (It might change in the future)

Make sure you read the precautions for flashing.

Then you must follow the procedure that correspond to your router in the DD-WRT installation page.

If you have questions about flashing you can ask for help in the forum.

Configure DD-WRT

Once your router is flashed:

• Connect the internet (WAN) port to your modem or existing router.
• Connect your computer to one of the LAN ports. (disable your static ip and let dhcp automaticaly configure your ip)
• Should should be able to connect to your router web management (http://192.168.1.1) (login: root, password: admin)
• Check that you can connect to the internet from your computer. If not, setup your internet connection.
  • If your existing router address is at same address (192.168.1.x) you must change your router IP (like 192.168.2.1)

• Once your internet is working, setup your wireless lan. Disable Encryption for your hotspot users.
• Check that you can connect to the internet from your wireless device
• If everything works, then simply enable chillispot with the given settings in Administration/Hotspot/Chillispot
  • Enable chillispot
  • Enable "Separate wifi from the lan bridge": This enable your wired lan to connect directly to the internet without going through chillispot. Your LAN is also protected from your wifi users.
  • On DHCP interface, select WLAN.
  • Set Radius server 1 to be the ip address of a your primary radius server
  • Set Radius server 2 to be the ip address of a your secondary radius server (use the same as server 1 or leave the zeros if you only have one)
  • Set dns server to be the ip address of a dns server
  • In Shared Key, put your radius secret password
  • Radius NASID is the radius name of your hotspot
  • Redirect Url is the address of the Uam Server, the web authentication portal.
  • UAM Secret is a secret password between the Redirect Url and the hotspot.
  • UAM Allowed is a list of website that unauthenticated users are allowed to use.

• Save and reboot your router
• Your hotspot should work now. If you tested your wifi device before setting up chillispot, restart it to get the new chillispot IPs.

Notes

You must make sure that your external router and your ISP accepts to forward UDP ports 1812 and 1813 to the internet. Chillispot makes radius requests to worldspot.net and cannot work if no response is received.

All your computers connected on the LAN ports will be protected from your hotspot users.

Note: Theses instructions should also work with DD-WRT v24beta. This new release brings a new very cool feature.

The multiple SSID allows to have several virtual wifi networks. One unencrypted for your hotspot users, one encrypted for your private use, (maybe one more encrypted also for your hotspot users... this will be tested in the future). Note that v24 is still beta and not yet released!
