madwifi - No Scan List - Atheros AR5001

[root@Kuba-Laptop ]# lspci | grep net
04:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02)
0c:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)

I compiled the madwifi drivers and tries to use them. Why? Because the "ath5k" have only 40% coverage where the Windows have 80%.

but ...

ath0   No scan results

from madwifi.org/Install-HOWTO/Commands.iwconfig.txt xD

#    iwlist scan
#        lo        Interface doesn't support scanning.
#        eth0      Interface doesn't support scanning.
#        ath0      No scan results
#            ( No scan results ---> is a bad thing )

Re: madwifi - No Scan List - Atheros AR5001

After you do "ifconfig ath0 up" you then need to get an IP address from the router with "dhcpcd". Then look at ifconfig again to make sure you then have an IP address. only then can you successfully run "iwlist ath0 scan".

You can make the process simpler and have the ifconfig and dhcpcd done automatically with "wicd" or some other wireless network manager.

That is incorrect. iwlist scan only deals with the wireless connection itself - the presence or absence of an ip address is irrelevant. Bringing the interface up is the only prerequisite for iwlist scan.
