Wireless Network

The SSID is i3 , there is no encryption, this is considered a feature (for the moment).

You may occasionally see an SSID of 3302 or 1216, these are the FIRST Robot control WLANs. They are completely isolated networks and are probably not very interesting to you.

LAN Addresses

Internally, we are using the supernet. It should sidestep most VPN overlap problems, should we establish any connections to other locations. At present, we are only using one subnet of this:


Static Hosts

If you have something that needs to be attached to the network at i3Detroit, a static IP address can be assigned to it. This is useful in cases where something like a printer or a tool needs to be on the network with a known address that doesn't change.

Most member and guest laptops, however, do not need one of these.

If you have something that needs a fixed address but can't be configured for one (for some reason), something known as a DHCP reservation can be applied. Please contact Joe B or Nate W to help you out with this.

Static hosts use the following settings:

IP address Take an unused address from the table below. Document which address you used. When in doubt, ping first.
Subnet mask
Default Gateway
DNS Server
DNS domain name i3detroit.local
Time / NTP server or (The LAN switch is also an NTP server)

The default DNS domain handed out for DHCP clients is i3detroit.local. If you have statically assigned a IP to something, and you want its hostname to be in DNS as your_hostname.i3detroit.local, we can add it to the local server. Post a request on the mailing list to have that taken care of.


Q: Can we open a port in the firewall for my XYZ server?

A: Probably not. The upstream bandwidth at the space is rather poor. You are welcome to suggest it, but be prepared to meet with significant resistance from your fellow members. Alternately, many of the members have COLO space that they might be willing to share. Make a proposal on the mailing list and turn on the charm.

Q: Let's get some better bandwidth at the space!

A: We now have 15mbit down, 2 up from WideOpenWest. If that's not enough pipe for you, we don't know what to say.
