I'm using Raspbian.

Every time I turn RPi on, the network monitor icon in bottom right corner says, that wlan0 has no connection at all or the connection is limited. wpa_gui gives error Could not get status from wpa_suplicant.

These are the config files:

/etc/network/interfaces

auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet static
  address 192.168.1.111
  netmask 255.255.255.0
  network 192.168.0.0
  broadcast 192.168.1.255
  gateway 192.168.1.1
allow-hotplug wlan0
iface wlan0 inet manual
  wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
iface home inet static
  address 192.168.1.110
  netmask 255.255.255.0
  network 192.168.0.0
  broadcast 192.168.1.255
  gateway 192.168.1.1
iface stalk inet dhcp

/etc/wpa_suplicant/wpa_suplicant.conf (also /etc/wpa.config is a link to this one)

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="my_ssid"
    psk="my_pass"
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=TKIP
    auth_alg=OPEN
    id_str="home"
    priority=15
}

network={
    ssid=""
    psk=""
    key_mgmt=NONE
    auth_alg=OPEN
    priority=1
    disabled=1
    id_str="stalk"
}

FYI: my network is using only static IP and WPA2. The ethernet connection works without problems. The wifi adapter (Modecom mc-un11c) is connected to powered USB hub.

To configure the files I used this manual.

What is wrong, why does the wifi connection not work?

Have you tried only setting the SSID and PSK? I was also using a static IP and WPA 2. I had a similar problem to yours, but when I only configured the SSID and PSK it worked.

If you using hidden network you have to add:

wpa-scan-ssid 1

to /etc/network/interfaces

Based on ingo's answer, I thought of using dhcpcd.
I am Sharing my experience (Likely to be useful to newbee and irritating to masters)
I kept my old /etc/network/interface file as it is.
First, as soon as dhcpcd was started, my ssh connection hanged
After first reboot, it momentarily pinged to old( 192.168.1.2 , see question above) address. But in few seconds ping stopped.
After second reboot, I could ping and ssh 192.168.1.2.
To my surprise, Now had two ips for eth0 and wlan0

3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 02:81:79:1b:3c:09 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.3/24 brd 192.168.1.255 scope global eth0
   valid_lft forever preferred_lft forever
inet 192.168.1.13/24 brd 192.168.1.255 scope global secondary noprefixroute eth0
   valid_lft forever preferred_lft forever
inet6 fe80::81:79ff:fe1b:3c09/64 scope link 
   valid_lft forever preferred_lft forever
4: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 12:81:79:1b:3c:09 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.2/24 brd 192.168.1.255 scope global wlan0
   valid_lft forever preferred_lft forever
inet 192.168.1.13/24 brd 192.168.1.255 scope global secondary noprefixroute wlan0 valid_lft forever preferred_lft forever
inet6 fe80::1081:79ff:fe1b:3c09/64 scope link 
   valid_lft forever preferred_lft forever

I think ip address of both interfaces and dhcpcd are allotted.
All IP are pinging and connecting.
What is syntax for writing static wifi (and LAN) ip in dhcpcd?

With respect to my question at https://raspberrypi.stackexchange.com/a/117643/125839 I found that,editing /etc/dhcpcd.conf file (and do not confuse with /etc/dhcp/dhcclient.conf) can force dhcpdcd to give static ip of out choice.
example (add following in /etc/dhcpcd.conf):

interface eth0
static ip_address=192.168.1.3/24
static routers=192.168.1.1
static domain_name_servers=8.8.8.8

interface wlan0
static ip_address=192.168.1.2/24
static routers=192.168.1.1
static domain_name_servers=8.8.8.8

also edit /etc/wpa_supplicant/wpa_supplicant.conf for wifi

country=IN
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
    ssid="My_wifi"
    psk="My_Pass"
}

With dhcpcd installed and /etc/dhcpcd.conf and /etc/wpa_supplicant/wpa_supplicant.conf completes static IP allocation.
Now, /etc/network/interfaces file can only contain declaration of loopback only Now, my only eth0 starts, wlan0 is not working. Any idea for wrong configuration?

Read 100s of answers for How to setup static wifi on pi
I am summarizing my experience:
Relevant for oragepi / rasberrypi
Why: a pi attached to USB power supply with no 'strings' attached is the goal

  • Connect with LAN (Because Wifi is not set / may get broken during trial

  • systemctl disable NetworkManager (to disable nmtui)

  • content of /etc/network/interfaces

    allow-hotplug eth0
iface eth0 inet static
 address 192.168.1.3
 netmask 255.255.255.0
 gateway 192.168.1.1

    #auto wlan0
    allow-hotplug wlan0
    iface wlan0 inet static
     address 192.168.1.2
     netmask 255.255.255.0
     gateway 192.168.1.1
     wpa-ssid XYZ
     wpa-psk ABC

  • There will be many post saying that gateway line can not be duplicated. But you can

  • wpa-ssid and wpa-psk do not need inverted comma

  • wpa-psk need not be in Hex

  • There will be many post saying that

    • only one of the two is active.
    • eth0 dominating on wlan0.
    • eth0 disconnected disables wlan0.

  • But all that is due to auto eth0 instead use allow-hotplug eth0

  • auto activates by default.

  • allow-hotplug activates only if connected

No need for wpa-supplicant config files
This way both LAN and wifi works with static ip
