Client can access the internet connected to switch, but not to WAP

[billydailey]

I have a 4351 connected to the Internet using a WLC 9800L. the 4351 is connected to a switch which is connected to the Waps, which are 9166s.  When i connect a laptop wirelessly to the WAP and login, it does pull an IPV6 address, but will not browse the internet.  If i plug the laptop into the same switchport the WAP is in, and configure the port for an access port vlan 301, it pulls an ipv6 address and browses, youtubes, etc.

What am I missing?

I am using vlan 100 for management and 301 for clients.  Here is a switchport configuration:

interface GigabitEthernet1/0/3
description WAP Connect
switchport access vlan 100
switchport trunk allowed vlan 100,301
load-interval 30

 - What device model is  the 4351 ? What is the network topology ? (and or  provide a screenshot) ,

Your switchport config is a bit of a mixed mess of access and trunk port config.  It's not configured as a trunk and you have access vlan 100 configured so I'll assume it's in access mode which means ONLY vlan 100 is being used.

Try this:
interface GigabitEthernet1/0/3
switchport mode trunk
switchport trunk native vlan 100
switchport trunk allowed vlan 100,301
! Only 1 of the portfast commands will work - depends on switch model and IOS version
spanning-tree portfast trunk
spanning-tree portfast edge trunk
spanning-tree bpdufilter enable
spanning-tree bpduguard disable
speed auto
duplex auto
cdp enable
end

This presumes you're using an SSID configured for flexconnect local switching on vlan 301.
If the AP is in local mode and the SSID is centrally switched then vlan 301 needs to be configured on the WLC and the WLC trunk port.
