Open Wireless

Both my brother and the local makerspace’s Brian Duggan shared the link to the EFF’s Why We Need An Open Wireless Movement. Steven, because he’s the only person he knows who actually does run an open access point for his home network, and Brian because the local meshing network access point project is already able to provide this part of the necessary functionality.

At the meeting last night with some of access point folks, we got a quick demo of how to configure an access point running OpenWrt so that it provided both a closed network with access to the LAN and an open network that only had access to the WAN (hence, no access to local servers, printers, etc.).

The demo didn’t go as far as to show how to configure the system with quality of service limitations on the open network (so that random strangers can use your network, but can’t suck down all your bandwidth). Figuring that out will be one of my next steps.

There’s some info on OpenWrt’s quality of service page, but it’d be really nice to have an example with some appropriate settings that would allow some basic email and web surfing while leaving most of the bandwidth of a typical cable or DSL connection available for the connection owner. I haven’t found that yet. (Actually, I think I understand why it doesn’t exist. The upload and download speeds are set in kBits/s, so the correct values depend on the speed of your underlying connection. Values that shared 10% of a fast cable-modem connection could consume a large fraction of a DSL connection. Still, it’d be nice if there were some suggested values for typical configurations.)
