I do not mind that it is a useful suggestion in general and should be
followed, but I am curious if it has ever helped you in specific cases
of intel wifi cards.
My experience with it is far from being positive. Some days firmware
crashes are rare, some periods of time they happen every minute. I have
not identified reasons, so results of debugging attempts would be
unreliable. Sometimes restarting of the router helps. That is why I
suspect that access points around may affect my connection.
My impression is that version of driver in backports kernel is more
stable, however in addition I downloaded firmware newer than 72.
There are enough discussions, bugs, various suggestions concerning
parameters of kernel modules. Downgrading firmware did not helped me. I
have not noticed any improvements from disabling power save mode.
Some links:

The relevant line from
lspci -nn
output should help to identify wifi adapter model.
