Broadcom 4318 wireless again ...

[Klaus-Peter Schrage]

I have been struggling with my wireless since FC 5. Although on a 
comparatively rare hardware (Apple ibook - ppc), problems were similar 
to those reported by users with a different architecture. I have tried 
the old-style driver (bcm43xx) as well as the new-style one 
(bcm43xx_mac80211). After a lot of reading, some reports to bugzilla 
(which turned out to be quite responsive and helpful, btw), and long and 
sometimes frustrating experimentation, I got both drivers to associate 
somehow, but eventually I stuck with the old one which seemed to be more 
reliable and gave me a stable connection with WPA encryption.

Whenever a new kernel comes up (and when I have some spare time) I give 
the new driver another try. Now, today we have 2.6.22.4-65 (Sunday 
afternoon),  so I fired up the new driver again (won't give you the 
details now how I did the change) which is now called b43, but the name 
is aliased to bcm43xx_mac8021.

Now to my problem: I can activate the device with the new driver, run 
wpa_supplicant to associate to my access point, get an ip address with 
dhclient, and iwconfig tells me that there is a connection established 
with a speed of 54 Mbits/s, but - I can't get to the Internet. Pings are 
extremely slow, when trying to go to a web site the browser tells me 
that it is performing a look up but it ends up in an error (can't connect).
So what's going on there? There seems to be nothing wrong in the output 
of dmesg, ifconfig, iwconfig ...
