Hello Folks,
I am following this guide:
I have successfully configured a C3750X switch into a few Vlans, one of which is hosting an Aironet 1142. The C3750 provides IP addresses via DHCP through the Aironet to a client.
I have a router connected to port 48 of the switch
The client can ping the switch in the 192.168.110.x and 192.168.120.x subnets.
The client can ping the switch port connected to the router 192.168.101.250.
The client cannot ping the router interface. I do not know why. I have tried both a routeable and Vlan based interface between the switch and the router.
Neither of these options work - ping fails from client to router (but works to last hop on switch).
eg:
Tracing route to 192.168.101.250 over a maximum of 30 hops
1 2ms 2ms 3ms 192.168.101.250
If someone could suggest where I need to look to be able to route from the WiFi client to the router it would be appreciated.
Thank you.

Hello,
I only see a partial switch config ? Which IP address are you pinging from ?
Save the running config of the switch into a text (txt) file and attach them, this should work.
