Guest Wifi with Limited Bandwidth

In many cases you would like to have a wifi network that can be used by guests to your place but not allow them to access your Network and to have limitations on the speed of their Internet connection.

This tutorial will show how to set up a guest wifi and, for thos routers that have it installed, use QOS to limit the speed of the Internet connection.

This tutorial is for routers not running the GoldenOrb version of ROOter. If you are using GoldenOrb then see here for an easier way to add a Guest Wifi.

Create a New Wireless Controller

Log onto the web GUI of your router and go to Network and then Wifi.

Click on the Add button for the wifi radio (2.4 or 5 Ghz) that you wish to use. A new Interface will be created.

Enter guest as the name (ESSID) of this interface. Check the create box under Network and enter guest as the name.

If you wish to password protect the Wifi then click on the Wireless Security tab and set up security.

Click on Save & Apply.

If you are not automatically taken there, go to Network and then Interfaces and click on the Edit button of the GUEST Interface.

Change the Protocol to Static Address and click on the Switch Protocol button.

Click on the Setup DHCP Server button. Leave all the settings alone.

Move up to the Common Configuration section.

Enter an IPv4 Address which is not in the same domain as the router. If your router IP Address is 192.168.1.1 (default) then select something like 192.168.3.1. Set the IPv4 Netmask as shown. Click on Save & Apply.

Next, click on the Firewall Settings tab.

Select the unspecified zone and enter guest as the name. Click on Save & Apply.

Now go to Network and then Firewall. Click on the Traffic Rules tab.

Scroll down until you reach the Open Ports section

Enter GuestDNS as the Name and 53 as the External Port. Click on the Add button.

Click on the Edit button for the GuestDNS Rule.

Set the Source Zone to guest and the Destination Zone to Device. Click on Save & Apply.

Go back to the Open Ports section again.

Enter GuestDHCP as the Name, set the Protocol to UDP and the External Port to 67-68. Click on the Add button.

Click on the Edit button of the GuestDHCP rule.

Set the Source Zone to guest and the Destination Zone to Device. Click on Save & Apply.

Click on the General Setting tab and scroll down to the Zones section.

Click on the Edit button of the guest zone. Scroll down to Inter-Zone Forwarding.

In the Destination zone section check the WAN zone. Click on Save & Apply.

The Guest Wifi is now set up and ready for use.

Limit Speed using QOS

If you wish to limit the speed of the Internet connection on the Guest Wifi it can be done using QOS. If your router has QOS installed on it then go to Network and then to QOS.

Enter guest into the Add Interface box and click on the Add button. A new QOS Interface will be created.

In the GUEST Interface section check the Enable box.

Contrary to what you would think, the Download speed is the speed of the connection to the Internet and the Upload speed is the speed of the connection from the Internet.

Enter the speeds you wish to limit the Guest Wifi Internet. Click on Save & Apply.

Next, go to System and then to Startup. Scroll down to the QOS entry.

Click on the QOS Restart button. After a few seconds the page will refresh and QOS will be active.

If you wish to change the speeds on the QOS page then you will have to restart QOS again.
