    "Just compile in the kernel "hostap" patches, and away you go!"

    you mean I'd have to compile my kernel??? I've managed to go 5 years now with Linux without ever having to compile a kernel...

    Hyperlinktech has a nice selection of wireless gear, amps, antennas, spliters, etc. They seem like there pricing is high but the quality of the product is good.

    Yah, we've been working on a couple of different ways to check that the AP has either moved, changed SSID, or has been taken out of service. The SSID name should have changed if any wardrivers found the unit with the new name, however. Same for WEP charachteristics.

  26. WiFi Defaults? by drewzhrodague · · Score: 2, Informative

    Actually, not. You'd think that consumers would read the snippets of documentation that come with the box, understand what they're doing when they turn this thing on, and pipe their computers into it. This is not the case. ~70% is unencrypted, and about 30% are totally default. What's the best way to get users to understand this?

    I figure, shipping the unit with the factory defaults as nothing working, and make the user read/configure the thing first.

    An access point serves as a bridge between your wired LAN and your wirelessed computers. A router will break that functionality as the network address will change. Useless for business.

  29. the cost-benefit analysis of doing it yourself... by deviator · · Score: 2, Informative

    you know, if you want to do it for a hobby so you can learn about WiFi, cool. Otherwise, the benefits of "rolling your own" access point on Linux are minimal. Dedicated hardware access points are really a miracle of engineering--they're full-featured yet cheaper than dirt (you can often pick them up for less than $30).

    Unless your time is worth *nothing* most people would be better served by simply purchasing a dedicated hardware access point (most are powered by Linux anyhow).
