I've used iwlist iface peers and I've no idea what will be
Once they will replace it I'll decide to use scan - but for now I use peers

I've used for some tests /proc info because I feel it more independent from
other commands

I've never used athstats for any info so I don't know.

for hostap driver, that was the main driver used by wifimon, client
noise and signal levels were only in /proc/net/wireless
iwconfig shown some constant values that time

just from /proc/net/wireless
no other way is known to me (maybe there is some)

just from /proc/net/wireless
no other way is known to me (maybe there is some)

> 7. In w_pkts() what is $wl_pksize for?
wl_pksize is the "maximum number - 1" that can be shown in percentage of packets
when -ppkts param is used
it results in next cases
0 - no packet found at this bitrate
1..99 - one or more packet found (99 is the maximum)
as you can see there is no 100% value and the reason is in the fact 100% is three
digit number and it looks better aligned when only two digit numbers are used

wait a moment
you probably missed the meaning of bash formulas
"+" operator is used as the last one and it means there is no "$wl_nt + 1"

there is
wl_nt1n=$(($wl_pksize * $wl_nt1 / $wl_nt + 1))
that is handled like
wl_nt1n=$((($wl_pksize * $wl_nt1 / $wl_nt) + 1))

it results in a number 1..99 - one or more packet found (99 is the maximum)
