Hi all!
Is there any way to setup a static IP on WLAN?
(I mean a way for a noob like me!) 
tnks!
You need to inform yourself in the internet and apply the changes in the webconf.
I would start with changes in the wpa_supplicant (editable through webconf)
iface <your_if_name> inet static
address 192.168.0.20
netmask 255.255.255.0
network 192.168.0.255
gateway 192.168.0.1
tnks! do you mean on browser via IP on the menu System/Wifi/advancedConfig?
exactly…yes
Ok perfect… so last (I hope!) question:
“our_if_name” is, for example, wlan0? or you mean my wifi SSID?
wlan0
the left column value of ifconfig
I also try to set the static ip via editing the wifi conf in System/Wifi/advancedConfig but not work…
with only the SSID information the wifi works fine in dhcp mode …when i put the
iface wlan0 inet static
address 192.168.1.222
netmask 255.255.255.0
network 192.168.0.255 ??? what means??
gateway 192.168.1.1
the wlan not work…
There are tons of tutorial and methods to set a static IP on the rPI, and each one of them works for just two people on the planet 
At the beginning of this tutorial there is the method I used on two rPIs that I installed at work.

At home, I always use reservations on my DHCP server. Way easier…
Thank you @Axeman …i also found some different metods…but needs to edit also other file not only the wpa_supplicant…and not working with the webconf…
ok Axeman… success! after your tutorial I have to… reinstall my .img from scratch! LOL!
Let’s try again (Want to evolve from noob to complete inexperienced…)
