Cannot ping local network (Wifi only)

[fulvio]

I have setup Wifi using a USB dongle.

I can SSH into my Pi now that's not connected via ethernet to prove that Wifi works.

Pinging Google works just fine and I can surf the web, check email, etc.

The problem is that I can't PING the IP address of devices connected to the same Wifi network.

The problem is that if I'm connected via Wifi I can't PING my iPhone that's connected to the same Wifi network.

iPhone (Wifi): 192.168.10.66 - Destination Host Unreachable.
Other Desktop (Ethernet): 192.168.10.94 - Working just fine.

This is my current /etc/network/interface:

Code: Select all

# The ethernet interface.
auto lo

iface lo inet loopback
iface eth0 inet dhcp

# The wireless interface.
allow-hotplug wlan0
auto wlan0

iface default inet dhcp
iface wlan0 inet dhcp

wpa-ssid "HOME-WACCESS"
wpa-psk "FOOBAR"

UPDATE:

This is my Wifi "ifconfig":

Code: Select all

I have the same problem, however it seems to be specific to my wireless router at home, if I connect to a Wifi hotspot created by my phone I can ping other devices connected to this WLAN and the PI responds to pings. If I'm connected to my Home WLAN I can only ping my router and my Ubuntu PC all other devices do not respond. The PI itself is un-pingable and will not respond to SSH, but can ping and http to devices on the Internet.

I have the same issue (everything works on ethernet, but cannot ping or ssh into the pi over wifi). The pi itself can ping out and browse the internet over wifi just fine. Any solutions?

Some access points do not allow things on the wifi to talk to each other. Its like an internet cafe setting to stop someone hacking your laptop from theirs. Have a look on your access point or ADSL router for its wireless settings.
