Regarding wscan: (see note1/note2 below), I felt that my 1st attempt at teaching if_wi.c to do the AP scan function was flakey and problematic, so I recently finished a 2nd pass. Basically I couldn't get wscan to work with it, therefore I started over and have replumbed how it works. The result is findable at ftp://ftp.cs.pdx.edu/pub/mobile/wscan2.0.tar.gz This is a 2nd and "experimental" release of wscan for freebsd ONLY, and wscan now has 3 "modes", including previous managed, ad hoc, and now "apscan" (wscan -A). wscan is an X-based signal strength meter for lucent/prism2 cards. (So far, prism2 cards lack a noise indication). Anyway, the tar blob includes the kernel patches needed for if_wi.c. These patches are findable in the ./wi subdirectory and have no functionality other than AP scanning. These is also a modified wicontrol so that one can do AP scanning at a lower level. E.g., temeraire# wicontrol -i wi0 -A start temeraire# wicontrol -i wi0 -A poll ap[0]: netname: binksys channel: 1 quality/signal/noise: 22 -77 -99 BSSID - 0:50:18:5:d0:f8 beacon interval: 90 capinfo: 0x1: ESS ap[1]: netname: binksys channel: 6 quality/signal/noise: 16 -83 -99 BSSID - 0:2:2d:2a:1f:d1 beacon interval: 100 capinfo: 0x1: ESS temeraire# wicontrol -i wi0 -A stop temeraire# wscan has some feature improvements too. The "log" button now prints out signal/noise/quality (should have done that in the 1st place), and the initial "directory" panel now scrolls. If it works for you please let me know. If it doesn't work for you, 1. I said it was experimental and 2. please tell me your firmware number/s and what release of BSD you are using. note1: wscan is intended as a visual signal strength meter. I am very fond of the fact that lucent cards can easily take another antennae. And give signal/noise/quality. note2: no slights intended in the direction of airtools. I wouldn't have been able to figure out how to do the apscan thing without hints from that direction and elsewhere. regards, Jim Binkley jrb@cs.pdx.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
