Those values are completely bogus. In the official bcm43xx-mac80211 trees, the code gives more realistic values, but those patches are not in FC7. > [EMAIL PROTECTED] ~]# iwconfig > lo no wireless extensions. > > wmaster0 no wireless extensions. > > wlan0 IEEE 802.11g ESSID:"Guest Access" > Mode:Managed Frequency:2.462 GHz Access Point: XX:XX:XX:XX:XX:XX > Bit Rate=18 Mb/s > Retry min limit:7 RTS thr:off Fragment thr=2346 B > Encryption key:XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XX > Link Quality=193/146 Signal level=-238 dBm Noise level=-73 dBm > Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 > Tx excessive retries:0 Invalid misc:0 Missed beacon:0 > > eth0 no wireless extensions. > > vmnet8 no wireless extensions. > <<< > But wait, what the hell is wmaster0? In FC6 there was no wmaster0! Whatever. That is a feature of mac80211. It supports multiple devices, whereas bcm43xx-softmac (the old one) does not. > Now look again into ifconfig.

So where is a problem? I hope someone of you could help me. > Please! The problem is one of signal strength/maximum transmission rate with bcm43xx_mac80211. The current state in Michael Beusch's git tree is better than that of FC7, but only a little better. One change is that the driver initializes to 1 Mbs rather than 54 Mbs, which greatly aids the authentication/association process. > cu Floh > PS: With the newer version of bcm43xx there is no need to 'modprobe bcm43xx' > (I mean 'bcm43xx' not 'bcm43xx_mac80211'), am I right? Yes. > PS2: I've tried with Windows-Vista-driver for broadcom-chip, but > unfortunatelly it's too new for fwcutter. :( Your firmware is not the problem and should be OK.
