The software used the wireless card and scans every x ms so if course this will vary. Signal will always change and even if you have two or 3 devices with the same tool, each will read differently. This is how it is.<BR /><BR />Sent from Cisco Technical Support iPhone App</P></BODY></HTML> Fri, 07 Mar 2014 11:26:39 GMT https://community.cisco.com/t5/wireless/ssid-tx-power-question/m-p/2476694#M76260 Scott Fella 2014-03-07T11:26:39Z SSID Tx POWER question https://community.cisco.com/t5/wireless/ssid-tx-power-question/m-p/2476695#M76261 <HTML><HEAD></HEAD><BODY><P>Hi Ulises,</P><P></P><P>As mentioned by <STRONG>Scott</STRONG> it varies as you can see in the below screenshot.</P><P></P><P>am using 4 different ssid's and u can see there is a deviation in the Tx power.</P><P></P><P></P><P><IMG src="https://community.cisco.com/legacyfs/online/legacy/6/4/4/183446-Test.png" alt="Test.png" class="jive-image-thumbnail jive-image" onclick="" width="450" /></P></BODY></HTML> Fri, 07 Mar 2014 17:34:30 GMT https://community.cisco.com/t5/wireless/ssid-tx-power-question/m-p/2476695#M76261 Ashish Chandra 2014-03-07T17:34:30Z
