  1. If OS on Linksys is some prior version of DD-WRT, telnet or SSH to router.
  2. The following commands will erase the nvram. This means you must be able to connect to the router via the lan port of the WLAN port to do any further configuration .
  3. Connect to the router. The password is now admin
  4. Upload the version of DD-WRT that you plan to use.
  5. Repeat step 2.
  6. Set the IP address on the WAN port to a static IP Address or somehow be able to know the IP address
  7. Configure the router for remote management.
  8. Reconnect to the router and upload the firmware. See below.
  9. Reconnect to the router via the WAN port. This is required because you will now disable DHCP on the Main setting page.
  10. Disable DHCP on the Main setting page
  11. Reconnect to the router, set the output power to 250mw using the Wireless Advanced Settings page
  12. Reconnect to the router, disable Block Anonymous IMCP Requests and disable the Firewall
  13. Reconnect to the router
    1. enable SSH and telnet
    2. enable reboot at 3:00 AM
    3. configure Chillispot as follows
    4. set Radius server 1 to be the ip address of a your primary radius server
    5. set Radius server 2 to be the ip address of a your secondary radius server (use the same as server 1 if you only have one)
    6. set dns server to be the ip address of a dns server
    7. set radius secret to be your radius secret password
    8. set dhcp interface to be LAN and WLAN
    9. paste these entries into the additional Chillispot options:
      radiuslisten the ipaddress set in step 4
      radiusauthport 1812
      radiusacctport 1813
      macauth required if you want to use the mac address as the username
      macsuffix @some_name - This will be the realm used in RADIUS authentication
      macpasswd some value if you want to pass this parameter
      radiusnasid some_name_with_no_spaces
      net 10.186.179.0/24 any net of your choosing. This is the net assigned to Wireless Clients
      domain the domain name supplied by the Chillispot DHCP server
      uamallowed any web address allowed without RADIS authentication
      dns2 the ip address of a dns server - optional
    10. Make changes to radius listen port ip so that it matches the WAN port address set in step 4 above
    11. Change the entry for net if desired. This is the DHCP network clients are assigned to when they connect
  14. DO NOT enable Chillispot. Save setting and reboot router
  15. Now enable Chillispot and reboot router
  16. Go to Settings/Advanced Routing/Show Routing Tables. If Chillispot started, you should see the net specified in step 13(i).
  17. Chillispot will not start unless it can see the dns server specified in step 11(f).
  18. Other considerations
