I spotted this over on HaikuNews, reported by Kian. Michael Lotz, who's involved in more projects than I can count (I suck at math), has checked in (and now released over @ BeBits) his Intel Pro Wireless 2100 (vendor ID 0x8086 and device ID 0x1043) wireless driver for Haiku. The driver supports WEP encryption, in 64 and 128-bit flavours, and works in ad-hoc, infra or monitoring mode.

As Kian wrote, after an e-mail from Michael, the driver works in R5 and was commited by Michael over a wifi connection, using it, yes you guessed it, his own driver. So if you have such a device on your laptop, head over to BeBits and download it, and don't forget to get the firmware the firmware is included (thanks Michael). As always, provide Michael with feedback, even if "just" to thank him.
