Basically I need to reduce the RSSI strength. I want my access point to monitor traffic only for my office premises.

My futile attempts : I changed the wireless config /etc/wireless/config

config wifi-device 'radio0'
    option type 'mac80211'
    option channel '11'
    option macaddr '0xff:0xff:0xff:0xff:0xff:0xff'
    option hwmode '11ng'
    option htmode 'HT20'
    list ht_capab 'SHORT-GI-20'
    list ht_capab 'SHORT-GI-40'
    list ht_capab 'RX-STBC1'
    list ht_capab 'DSSS_CCK-40'
    #option txpower '10'
    #option distance '5'
    option country 'IN'
    option disabled '0'

The airodump-ng output. It shows me the same amount of requests before adding these options in the above configuration

option txpower '10'

option distance '5'

I also saw a link which says that these values do not change at the lower level, inspite of changing the configuration. Any help would be appreciated.

Tx power does not reduce your receive sensitivity. It only affects the packages you send. If you speak in a low voice you still hear everyone close to you speaking loudly.

There is probably a better solution, but you could calculate the distance to each transmitter and keep only packets of the one in your distance of interest.
