I promised that I could set up a wifi hotspot for a meeting where there is no internet access. Pure hubris.
I ordered and received a cellular broadband modem in less than a week. It only talks to Windows, so I couldn't just mimic the configuration that I have with my home wifi configuration via Linux. I started by trying to figure out the right configuration for the hand-me-down Apple Airport that I would be using. That turns out to be a bad idea, since WinXP internet connection sharing demands that you have a pipe configured by your ISP at one end and the magic IP address of 192.168.0.1 at the other. There goes my preferred 10.0.0.0 network setup.
So here is the configuration that I found to work:
WinXP
- cell modem: CHAP as per ISP-defined configuration
- advanced network properties:
- Allow other network users to connect through this device
- Establish dial-up connection on demand
- Shared with network: wired LAN
- advanced network properties:
- wired ethernet: 192.168.0.1 as per connection sharing rules. This is set automatically and cannot be changed.
Airport
- ethernet uplink: DHCP
- dhcp server off (it is provided by WinXP connection sharing)
