We're going to need more information on you pfSense install here to help you.
It's a vitual install? What hypervisor?
How is this USB device connected?In general though if you can connect to the webgui from LAN and the pfSense box itself can ping out on WAN then you have a missing or incorrect default route and/or no NAT.
Both those things can be caused by incorrectly putting a gateway on the LAN interface so check that first.

@stephenw10 thanks sir sorry If my question is very general hehe.. It is my first time to use this..
I have a computer then i just download pfsense software then create a virtual on oracle virtual machine.
WAN connection connected on the on-board lan on my computer then I purchase a usb lan plug on my computer..
I used USB lan for lan connection. then on usb lan i plug a utp cable going to my laptop.. -
Ok, so Virtual Box.
Lets, see screenshots from:
System > Routing > Gateways
Firewall > NAT > Outbound
Diag > RoutesSteve

I already access the GUI of pfsense sir.. I can ping out also on the wan its connected .. my worry sir is my laptop cant connected on the internet.

Hmm, OK that all looks fine.
So by default you would have a firewall rule allowing all traffic from the LAN subnet out. Is that still in place?
Are LAN side clients getting a DHCP lease from pfSense? If you've configured them statically (or there is another dhcp server in the subnet) the clients may not be using 192.168.14.1 as theirt default route.

@stephenw10 hmmm I already turn my computer sir and also my laptop I need to rest sir hehe but sir based on your question . the ip address of my laptop is already set from obtain and getting from the dhcp server. I already set from 192.168.14.2 - 192.168.14.254.
-
I can see my laptop on the DCHP lease pfsense (192.168.14.10 - laptop IP address)
-
Ok, go to Diag > Ping in the webgui and try to ping 8.8.8.8 but select the LAN as the source IP.
That should work and proves the NAT is working.
Can we see the LAN firewall rules?

Ok, great. Try that ping again but set the LAN interface as the source address.
-
is this correct sir?
-
that is my laptop sir, as you can see i cant ping 8.8.8.8 from the laptop
-
Hmm, OK that all looks good. Except it's not working.
Run the ping to 8.8.8.8 from your laptop continually and then check the states in Diag > States. Filter that by 8.8.8.8 to see what states are being opened.
