^^ hello everyone. last time, I tested 3com pci card (atheros) and now testing zd1211b. the general product name is AG-760A.(usb dongle) (only for using 802.11a ad-hoc) I took a look at the source : zd_mac.c , zd_usb.c, etc... In these files, I could see the "/* FIXME for 802.11a*/ comment block. so, I changed 2GHZ to 5GHZ and 24GHZ to 52GHZ etc..(also with productid) the device was registered and zd1211rw_mac80211 drivers were loaded. but when doing iwlist [device] channel, I can only show me 2Ghz channels... how do I fix for 802.11a? thanks. P.S if you've guarantee stable operation for 802.11a(with ad-hoc), plz give me the product name ( i want to know the product models using 802.11a and being supported in current certified linux kernel driver) - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
