          Mode:Managed  Frequency:2.427 GHz  Access Point: D2:99:K2:54:DC:17 
          Bit Rate=65 Mb/s   Tx-Power=20 dBm 
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=49/70  Signal level=-61 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0

 current dbm showing 20 now we are going to increase to 30dbm . if it increased dbm 30 than your router signal also inceased to max..

USE these command to increase
