Lion Wifi Issues (2011 MBP) -- Anyone else seeing this?

hi all.

i've been having issues wifi connection ceasing work randomly. if turn off mbp's airport , turn on, things start working again (most of time).

seemed more prevalent 10.7, got better 10.7.1 , 10.7.2, , worse again since upgrading 10.7.3.

else experience sort of thing?

 

i experience time since switched lion. turn wifi off , on. it's annoying time fixes problem.
