hi.. i have 30-40 client and i want to change SSID,user password,NV2 preshared key,IP-services etc... with one click.Ddoes anyone know how to do this???

No you can't with one click..

I know this is possible. no need to enter all devices individually. must be a program or script for by entering the current parameters such as ip, port and password than by entering the changes we want new. and program should automatically send new data by ssh..api or telnet i dont know ...

You can try MobaXterm.
Log into all devices concurrently and then use Multi-Exec. Every character you type will be sent to all Sessions.

Or create a .rsc script which contains all the changes and then upload it to all devices by FTP and name it <yourscript>.auto.rsc - it'll thenm be executed automagically after upload.

thnks for MobaXterm
