Thanks, John! But I think my situation might be different; I left out one 
critical piece of info that causes me to believe it's a problem with the 
Airport Extreme. The macbook pro works just fine (constant bars) everywhere 
else -- with  my Linksys router at home, in hotels, airports... I might just be 
at the edge of its range and there's some other variable at work causing the 
signal to come and go. But I was thinking it was better prior to the upgrades.

I also have an Airport Express on the shelf. Perhaps I should try using it to 
boost the signal a bit and see what happens.

Subject: Re: [MacGroup] wavering Airport Extreme signal

Milt,

I have two Airport Extremes and six Airport Expresses tied to the Extremes.  I 
also updated to the latest firmware and noticed no change in signal strength 
anywhere in fact it stopped a problem I was having with the DSL Extreme each 
night, the upgrade stopped the problem.

I also experienced what you are with my last MacBook.  I took it to the Apple 
store and had a new airport card installed and it did no good so on the next 
trip they realized there was something wrong with the machine and since it had 
previous trips for repair and as I had Apple Care they offered to trade up to a 
new one.  

I am sure this is only because of the machine being sent off on three different 
occasions and now the 4th problem but what put it over the top was exactly what 
you are describing.  It was close to Christmas and I have completely organized 
our Christmas decorations with photo's taken all over the home where the 
decorations are to be placed.  My wife was using the laptop in each room and it 
would go from full bars to nothing several times in a short period of time.  I 
was constantly having to get out of iPhoto and back in, turning Airport off and 
back on, often rebooting to find full strength and then shortly being 
disconnected.

The new machine has full bars everywhere so it was some type problem with the 
MacBook.

Last year, I set-up an Airport Extreme network in my parent's home -- where I 
use occasionally my MBP. I work on the other end of the house from the router, 
but nonetheless I used to get a great signal -- typically all of the bars on 
the cone. However, lately the signal has been erratic. Sometimes I have all 
bars, but then rapidly changing to the one little dot at the bottom of the cone 
(which can make for VERY slow going depending on what I'm doing). 

I'm thinking this change coincides the latest Airport software update AND the 
firmware update for the Airport Extreme. I reverted to the former firmware, and 
this seemed to help a bit.

Ideas?

Many thanks,
Milt
