The Trinet network automatically provides basic network configurations via IPv4 DHCP, IPv6 Stateless Address Autoconfiguration (SLAAC) and DHCPv6. This means that the network typically "just works" after plugging in the computer to the wall socket, but in some cases network settings might be wrong due to previous use or other reasons. However, it's recommended to check the configurations at least once before using your computer for the first time on the Trinet network.
Users' own routers, firewalls and switches are permitted, but please take care of the following instructions:
- If a router/firewall has an Ethernet WAN port, use it to connect Trinet
- If a router/firewall does not have an Ethernet WAN port and you must use a LAN port to connect to Trinet:
- Disable all IPv4 DHCP services
- Disable all IPv6 Stateless Address Autoconfiguration (SLAAC) and DHCPv6 services
- Consider upgrading to a router with a dedicated Ethernet WAN port (see the hardware page)
- Disable Spanning-Tree Protocol from the device.
Trinet recommends regular switches if no wireless connection is needed. If wireless access is required, it's strongly recommended to use a router with a dedicated Ethernet WAN port. Interoperability of all router brands and models cannot be guaranteed. Please see more info about the devices and recommended hardware from here.
1. Turn on IPv4 DHCP and IPv6 autoconfiguration at your computer
macOS:
- Open "System Preferences"
- Select "Network"
- Select the network interface connected to Trinet
- Select "Advanced..."
- Select "TCP/IP" tab, and then change the following (if needed) to:
- "Configure IPv4": Using DHCP
- "Configure IPv6": Automatically
- Select "OK"
- Save changes by selecting "Apply"
Ubuntu Linux:
- Select "Edit Connections..." from NetworkManager
- Select the network interface connected to Trinet
- Select "Edit..."
- Select "IPv4 Settings" tab, and then change the following (if needed) to:
- "Method": Automatic (DHCP)
- Select "IPv6 Settings" tab, and then change the following (if needed) to:
- "Method": Automatic
- Save changes by selecting "Save..."
Windows 10:
- Select "Start" - "Settings"
- Open "Network & Internet"
- Select the network interface connected to Trinet, typically "Ethernet" or "WiFi"
- Select "Change adapter options" from the "Related settings" section on the right
- Right click a network interface which is connected to Trinet and select "Properties"
- Select "Networking" tab
- Select "Internet Protocol Version 4 (TCP/IPv4)" and then click "Properties"
- Change the following (if needed) to and then click "OK"
- "Obtain an IP address automatically"
- "Obtain DNS server address automatically"
- Select "Internet Protocol Version 6 (TCP/IPv6)" and then click "Properties"
- Change the following (if needed) to and then click "OK"
- "Obtain an IP address automatically"
- "Obtain DNS server address automatically"
- Save changes by selecting "OK"
2. Test your network connection by using ping
Tip for Windows users: the ping command works from the command prompt.
An example:
ping ns1.ayy.fi
If you get a reply, your connection is set up correctly. The reply looks something like this:
PING ns1.ayy.fi (82.130.0.1) 56(84) bytes of data. 64 bytes from ns1.ayy.fi (82.130.0.1): icmp_seq=1 ttl=63 time=0.140 ms 64 bytes from ns1.ayy.fi (82.130.0.1): icmp_seq=2 ttl=63 time=0.129 ms 64 bytes from ns1.ayy.fi (82.130.0.1): icmp_seq=3 ttl=63 time=0.136 ms 64 bytes from ns1.ayy.fi (82.130.0.1): icmp_seq=4 ttl=63 time=0.134 ms 64 bytes from ns1.ayy.fi (82.130.0.1): icmp_seq=5 ttl=63 time=0.135 ms
If you don't get a reply, try the following:
ping 82.130.0.1
If you get a reply now, your DNS (name server) settings are wrong.
If you still don't get a reply, check your IP and hardware settings. If they are correct, check that the network cable is connected properly. A light should light up in the network card, when you connect the cable.
If the light fails to appear, try changing the cable and, if possible, plugging into a different ethernet socket (e.g. flatmate's or other Trinet users's ethernet socket).
3. Other network info
All typically needed network settings will be assigned automatically via IPv4 DHCP or via IPv6 DHCPv6/Stateless Address Autoconfiguration (SLAAC). However, in some cases, the following network info might be beneficial to know:
