Devices in the same subnet cannot ping each other
I apologize for approaching you all in this manner but I have an
issue that I must resolve urgently. I am sure that it will be a very small
issue for you. I am at my wits end and that why I am posting here
I have installed a Cisco 1941w router and the router acts as
a DHCP server to all networks (including WiFi). Users can all browse the
internet and the users that are connected to the Cisco switches can all connect
to one another.
The issue is that devices that are connected wirelessly can browse the internet
but are unable to connect to one another (ping) or to other devices on the
other 4 networks. The default gateway that is set by the DHCP option is VLAN 1
(172.16.1.1) while the BVI1 interface has 172.16.1.31 (dhcp) IP address.
Lastly, I don't know if the issues are connected with the interface
Embedded-Service-Engine0/0 (I don't know what it does) which is in an up state
but protocol down state.
I will appreciate any comments.
