Trouble with wireless connection after update

[Richard W Harper]

I installed Ubuntu 8.04 beta, which seems to work fine.  My wireless 
ethernet and 
my printer installed without a problem.  The problem arose when I 
installed the 
313 updates.  I think a kernel update (now 2.6.24-12; I think that is not 
what
was installed with the original distribution); and updated to DCHP.  My 
wireless
ethernet card is now nonfunctional.  The card is an Airlink 101 using the 
ralink
RT2561/RT61 chipset.
Data:
lshw:  shows the rt61 as wmaster0 (which I think it should since the 
Ubuntu uses
mac80211 (linux wireless standard).  The actual drivers (rt61 and rt2x00 - 
pci) 
are loaded and virtual interfaces created, such as wlan0 in my case.
iwconfig:  shows the interfaces wmaster0 and wlan0 as it should (did when 
it was 
working). 
ifconfig:  returns three interfaces wmaster0-00 (not just wmaster0 - I 
think 
this is why ifup and dhclient cannot find the right interfaces); wlan0; 
and 
wlan0:avahi (which was not there at all when the connection was working).
iwlist:  iwlist wlan0 scan - shows the router as it should.
dhclient:  dhclient wlan0 - says:  wmaster0 unknown hardware address type 
801.
SO:  It looks as though things became confused when the kernel update (and 

built-in driver update) occurred. 
Question:  What to do?
Is there a way to completely unload the drivers and have them all reload
correctly?  Is there erroneous configuration information being saved 
somewhere?
Help appreciated.  I continue to do research on the problem.  Anyone else 
had
it and solved it?
