Just edit Wan interface configuration And you will be able to disable It.

And on the Address and VLAN's you can see the WAN interface at all 

 

 

What firmware version are you running?

Yes its disabled already for the VLAN

 

But the main issue is my WAN is getting V4 and V6 IP address at the same time using WAN1 only 

Maybe because its already disabled

But the WAN is getting v6 IP

So, there is one more option. Open a case with Meraki support. 😅

 I fixed slow internet disabling  ipv6 on the local vlans. Any chance you have that enabled?

Local VLAN's are disabled already 

its enabled on the WAN and getting both v4, and v6 but there is no option t disable V6

Your MX is receiving an IPv6 address on the WAN because the ISP is distributing one via DHCP6.

There is no way to disable the MX from receiving this address.

 

If you believe it's causing an issue, contact your ISP and ask that they disable IPv6 on the link. Or you could try contacting Meraki support and see if they can disable it on the MX from the backend (not sure if this is possible or not)
