| - | I will design an infrastructure for 802.11 cards to be used by Etherboot, and as many drivers for it as I have time for. Currently there is only one driver for any 802.11 device (prism2) and it's out-of-date and unsupported by any 802.11 infrastructure. My work will create that infrastructure, with the hopeful end result of a slim 802.11 layer that is versatile enough to support all common use cases and more driver development. I will implement at least one driver, probably two and maybe three, along with generic support for 802.11 features such as security (at least WEP and WPA Personal; WPA Enterprise is much more involved and probably out of this summer's scope) and scanning for available networks. | + | I will design an infrastructure for 802.11 cards to be used by gPXE, and as many drivers for it as I have time for.

| - | * Detailed regulatory code - it isn't worth the size the databases would take up; gPXE will take regulatory parameters from the access point's beacon frames, making it impossible to associate with a "hidden SSID" network on the 5GHz band (a real regulatory mess, 2.4GHz is fine) | + | * Detailed regulatory code - it isn't worth the size the databases would take up; gPXE will take regulatory parameters from the access point's beacon frames, making it impossible to associate with a "hidden SSID" network on the 5GHz band (a real regulatory mess; 2.4GHz is fine) |

| Weeks 6, 9-10: Useful WiFi features, which right now means support for encryption and a site survey (list all wireless networks around here). Encryption support is essential because of how many wireless networks use it, while a site survey is more "would be nice" for autoconfiguration or command-line convenience. | Weeks 6, 9-10: Useful WiFi features, which right now means support for encryption and a site survey (list all wireless networks around here).

| - | Weeks 7-8: probably physics olympiad | + | Weeks 7-8 (July 5-20) will be low-activity because I will be competing in the International Physics Olympiad. I have OK'ed this with the mentors and will do my best to accomplish at least the amount finished by the typical SoC student in an open summer. |
| Remaining time: If all's gone well so far, and I've got at least a couple of weeks left (depending on how hard it was for me to do the first one), implement another driver, for the ath5k Atheros chipset in fairly common use. If all's not gone well, fix the parts that aren't working. Clean up code, document, test, etc. | Remaining time: If all's gone well so far, and I've got at least a couple of weeks left (depending on how hard it was for me to do the first one), implement another driver, for the ath5k Atheros chipset in fairly common use.
